The Importance of Color in Landscaping

Jerry Palmer

Landscaping involves making a landscape attractive and functional by using hardscapes and softscapes. Hardscapes include pavers, patios, walkways, and walls, while softscapes include plants, trees, and flowers. Click https://www.landscapersharrisburgpa.com/ to learn more.

A well-designed landscape provides interest and beauty year-round. For visual interest, use a mix of plants with different textures and heights.

Landscapes can also become mini-ecosystems by attracting pollinators and reducing environmental pollutants. Spending time in a beautiful outdoor space can lower stress and promote wellness.

Color

Color is a powerful element of landscape design that can elevate your outdoor spaces. It has the ability to create focal points, enhance space and perspective, establish harmony, embrace seasonal transitions, promote relaxation, and much more. It’s important to understand the principles of color in landscaping and how to use them strategically for the best results.

The first principle is unity, which is establishing oneness among the chosen elements of the landscape. This could be using plants of the same size, color and kind of leaf, or colors that look similar. The second principle is contrast, which means choosing elements that are either contrasting or balancing each other. Using complementary colors, such as red and orange or blue and green, creates a vibrant and visually striking contrast. Similarly, using tertiary colors (colors that are created by mixing primary and secondary colors) provides balance and adds dimension to the landscape.

Lastly, we should consider the personality of the colors used. For example, warm colors (reds and yellows) tend to be more energizing, while cool colors (blues and purples) are more calming. Whether using them in flowers or in the hardscapes of your landscape, it’s also important to keep in mind the different shades of each color, which can be tints or shades. Tints are lighter versions of the color, while shades are darker variations of it. Choosing the right shade of a flower or plant can make a world of difference in your landscape.

Form

The shape of plants and hardscape features is referred to as form. Form gives a landscape a distinct character, whether it’s formal or informal, structured or wild. Form also plays a role in determining how the space feels and influences how light is used within the garden or landscape.

For example, straight lines can give an area a very formal feel while curved lines tend to create a more casual appearance. Plants can have different forms, too – pyramidal, rounded, vased, flat or spreading – and each has its own unique impact on the space. Using different forms within the design helps establish unity and contrast that keeps the design from becoming monotonous.

Hardscapes include man-made materials like paving stones, walkways and walls while softscapes are living organic elements like trees, shrubs and flowers. The combination of both of these elements along with the addition of water features and lighting, creates a well-rounded landscape design.

Structures like arbors and gazebos provide a transition point between softscape and hardscape. Or they can be a focal point in themselves, as in the case of a pergola adorned with vines like English ivy or clematis. The scale of all the design elements – their size, proportion and placement on the property – must be carefully considered to achieve balance and harmony in the landscape.

Contrast

Contrast highlights differences and adds interest to the landscape, making it more vibrant. It can be achieved through a variety of factors, including color, texture and size. Contrast can also be used to delineate functional spaces in the landscape, for example, a smooth water feature paired with a rugged rock garden or rounded flower beds contrasting with angular walkways.

Color contrast is one of the most noticeable aspects of a landscape and can be achieved by using complementary colors, such as red and green or blue and orange. It can also be used with different types of foliage or textures. For instance, the dark purple star-patterned leaves of Superbells(r) Morning Star(tm) calibrachoa can be paired with solid, bright green phlox.

Color contrast can even be used to create the illusion of depth and perspective. For instance, warm colors, such as reds and oranges, can be used to make objects appear closer than they are, while cool colors, like blues and greens, can make them seem farther away. Contrast can also be used to draw attention to specific focal points in the landscape by creating a dramatic backdrop for them, such as a red maple tree against a lush green lawn. Contrast can be further enhanced with the use of light, sound, and scent to evoke emotion or create a sense of tranquility. For example, soft background music or calming fountains can relax and calm visitors, while the pleasant scent of a blooming rose can soothe them.

Variety

When designing a landscape, it is important to incorporate variety. This will make the space more interesting and appealing. It will also help to keep the plants healthy. Variety is essential in landscaping because different plants require varying conditions to thrive. For example, some plants may prefer shade while others like full sun. By using a variety of plants, you can ensure that the right conditions are met for all the different species.

The use of contrasting shapes, colors, and textures is another way to add variety to a landscape. This creates a sense of transition and draws the eye throughout the landscape. It is important to keep in mind that this technique should be used sparingly, as excess repetition can detract from the overall look of a design.

Lines are another important aspect of landscaping. They create natural pathways for the eye to follow. Whether it is a perceived line, such as a row of trees or a walkway, or a physical path, lines can add interest to the garden.

Landscaping is an art and science that has many practical applications. It can enhance the beauty of your home and increase its value. It can also improve your quality of life by providing a place for recreation and relaxation. In addition, landscaping can reduce pollution and erosion and provide habitat for wildlife. It is important to choose a reliable contractor when planning your landscape.

Movement

Landscaping involves making changes to the overall appearance of an area of land. It can be done by adding or removing plants, changing the terrain and constructing structures like ponds, walkways, garden walls and more. It can also include the use of decorative elements like rocks and sculptures. Landscape can be used as an art form, and it can help improve the quality of life for those who live in a particular environment.

One example of movement in landscaping is incorporating curves into the design, which can create a sense of natural harmony. Another is using different types of lines to create interest. Upward lines, for example, can emphasize features and create a sense of energy or activity. Horizontal lines, meanwhile, can create feelings of repose and work to divide or tie spaces together.

Lastly, native plants can be an effective way to add movement to a yard. These plants are well-adapted to the local climate and soil conditions, which means they require less maintenance than non-native species. Additionally, they won’t interfere with the ecosystem if they spread beyond the property line.

Homeowners can increase the resale value of their homes with the addition of landscaping, but it’s also an excellent way to reduce energy costs and promote environmental sustainability. With the right plant selections, mounding, terracing and hardscaping, homeowners can achieve their dream landscape while remaining within their budget.

Focalization

Focalization is an essential design principle that involves the use of a feature to draw the eyes from one part of a landscape to another. This can be accomplished in a number of ways from utilizing contrasting colors to creating a visual hierarchy with a primary and secondary focal point.

Focal points can be nearly anything in the landscape including inanimate objects like boulders, benches and containers as well as living plants, trellises and arbors. Focal points often utilize a combination of different colors, shapes, and textures to create interest. They can also incorporate line to create a sense of movement, direction or distance. This may be achieved by utilizing straight lines to direct the eye or using curved lines to present a flowing effect.

The focal point is also important in creating a sense of destination as it allows you to guide people through your landscape creating a journey with an endpoint. It can also serve as a transition point between indoor and outdoor spaces making your home feel more like an extension of your yard.

Focal points can also be used to highlight key features of your landscape such as an entrance gate, a unique seating area or captivating garden bed. It is important to note, however, that you do not want your focal point to compete with other features in the landscape for attention. Adding too many focal points can overwhelm the space, confuse or distract viewers, and detract from their overall experience of the landscape.

Mold Testing – How to Identify Hidden Mold Growth

Jerry Palmer

Unlike home DIY kits, professional mold sampling includes a thorough visual inspection. This is the most accurate way to track down hidden mold growth that spore testing can’t catch.

Testing can identify a portion of the live (viable) molds in a sampled environment, but this misses and undercounts nonliving or dead molds. The health effects of these organisms depend on a person’s susceptibility to the mycotoxins they produce. Contact Mold Testing NYC now!

Mold growth and the spores it releases are airborne and can cause various symptoms, including nasal and sinus, throat, skin, and eye irritation. For some people with severe mold allergies, symptoms can be more serious, such as a dry hacking cough, wheezing, shortness of breath and persistently watery eyes. Identifying and correcting the mold problem is essential to preventing health problems and protecting building materials, household goods and furnishings from damage.

Mold can grow indoors in any climate, year-round, and is capable of consuming organic material, which can cause structural damage to buildings and furniture. It can also affect occupants in the spaces it invades, potentially leading to respiratory issues and other health problems. Early detection of mold helps prevent these problems, and is an important part of any property inspection.

The best way to detect mold is through careful detailed visual assessment and recognizing the odor of mold. Many molds produce a musty odor as they break down the organic material they are eating, and this odor is noticeable in most properties. Mold is often spotted as staining or fuzzy growth on building materials, such as walls, ceilings, and wood furniture. Water stains on surfaces and signs of condensation indicate high humidity levels, which are ideal for mold growth.

It is common to find moisture problems in homes, especially Florida, and these can be a significant contributing factor to the growth of mold. Routinely checking the areas around air conditioning and furnaces for standing water, drips on evaporator coils or on liner surfaces, as well as examining damp or cold walls and floors, can help spot potential problem spots before they lead to mold. The same goes for the area around any windows, where condensation can occur and may be indicative of a leak.

Air Samples

Air sampling is a method of collecting airborne mold spores to determine their number and type in a specific area. This is accomplished by pulling a metered amount of air through a special filter that traps any particulate including mold spores. This sample is then analyzed to determine the number and types of mold spores present in the air at that time and location. This sample is often compared to an outdoor control or baseline sample to help determine the extent of an indoor mold contamination.

One problem with this approach is that it only provides a snapshot of what is occurring at that moment. If the air sample is collected before or after a large disruption, such as someone opening a door, walking across the carpet, or moving an object in a room, the number of spores will greatly increase and may skew the results. This also misses any spores that are clinging to the walls, ceiling, or HVAC system where they may remain undetected.

An alternative to this method is Envirobiomics, which uses a DNA-based analysis called MSqPCR to identify the molds and their toxins in the air. This method is more accurate than an ambient air test because it does not depend on spores. It will identify the toxins produced by molds such as satosporium, stachybotrys chartarum, and other toxic fungal metabolites that are emitted into the air. It will also report the levels of endotoxins, which are a group of bacteria toxins from Gram-Negative bacteria that can contribute to Chronic Inflammatory Response Syndrome (CIRS).

In many scenarios, an ambient air test is still recommended because it does provide important information. However, a more comprehensive testing regimen is typically required to address a serious contamination. This will usually include surface samples, a clearance sample, and an independent air test. The clearance sample is used to prove that the mold spore count in the contained/remediation zone has returned to normal. Occasionally, an air test outside the remediation zone will also be conducted to ensure that the contamination is not being carried into unaffected areas of the home or building.

Swab Samples

Mold sampling involves taking a small sample of suspect materials and sending them to a laboratory for testing. The most common samples are surface swabs, air samples and bulk samples (cutting up small amounts of carpet, drywall or other porous materials). Surface swabs use what is essentially a sanitary Q-Tip with a cotton-like media rolled against the suspected material to collect spores and growth structures. The swab is then placed in a tube containing specialized fluid to preserve the sample for analysis.

The advantages of surface swab testing are that it is relatively quick and non-destructive. It can also be used to test wet or heavily soiled surfaces that may not respond well to other methods. It is important to note, however, that surface swabs aren’t able to identify the concentration of spores in the air, which is an important factor in determining if there is a mold issue.

Tape sampling is a more precise method than surface swabs and can be performed on most surfaces without causing damage. It can provide valuable information, including the species of mold present and the likelihood that it is producing spores. It can also help to pinpoint the source of a mold problem by identifying areas of higher spore counts.

ERMI and DNA-type tests are other more specialized forms of testing that can determine the specific genus of the mold. These tests are more expensive than a Bulk sample, but they can offer more accurate results.

Mycotoxins are toxic compounds produced by some types of mold and can have serious health effects in people if they are exposed to them. They are most commonly produced by Aspergillus and Penicillium molds, but can be created by other types of mold as well.

A mycotoxin test is a blood test that can detect the presence of these neurotoxins/poisons in a person’s body. These tests are usually only ordered by individuals who are concerned that they may be displaying symptoms of exposure to mycotoxins or have been diagnosed with certain medical conditions that are associated with mycotoxins. The CDC recommends only having these tests done by a licensed physician.

Bulk Samples

The best test method for determining the type of mold growth in a home is to collect a bulk sample. This is done by physically removing a small piece of the impacted material (such as drywall or baseboards) and sending it to the lab for testing. The lab can determine the genus and species of the mold growth, which is useful in deciding appropriate remediation strategies. Bulk sampling is also useful for identifying if mycotoxins (a type of neurotoxin/poison gas that can have negative health effects in humans) are present in the home. The mycotoxins can be ingested when occupants are exposed to dust particulates containing the mold spores, so it is important to have an accurate determination of what type of mold is in the home.

This type of testing is usually performed as a follow-up to other tests, such as a swab or tape lift sample, and to an Environmental Relative Moldiness Index (ERMI) sample. The ERMI test is not recommended for homes with visible mold growth because it does not provide enough information on what types of mold are in the air to properly inform remediation strategy.

In addition, a swab or tape-lift sample can only be collected from the surface of a substrate; it cannot determine what types of mold are in the dead air spaces behind walls, above ceilings, and underneath floors. That is why it is often necessary to use both a bulk sample and an air sample in conjunction with each other.

When using a bulk sample, take care not to disturb the suspected mold growth. It is important to wear gloves and not touch the suspect material, as contaminating the sample can alter the result of the laboratory analysis. It is also important to press the tape or swab on the surface in one location rather than pressing over a large area. Doing so may over-load the sample and ruin the microscopic mold structures in the adhesive areas of the tape or swab. It is also important to use a freezer bag, as these are stronger and make it easier for the lab to remove the samples for analysis.

Benefits of Metal Roofing

Jerry Palmer

Whether you live in a high-rise or suburban home, there’s no reason to settle for traditional tiles or shingles. A metal roof provides superior protection while adding modern appeal to your property.

Avoid the cheapest felt underlayment, which will soak into attics, insulation, and framing. Instead, invest in a moisture-resistant synthetic underlayment. Contact Metal Roofing Erie PA now!

Metal roofing costs more than shingles upfront but lasts for decades, saving homeowners money on home maintenance and repair expenses and homeowner’s insurance premiums. Metal roofs typically have a reflective solar coating, which reduces heat buildup and lowers air conditioning costs. They’re also much quieter than shingle roofs, helping to reduce noise in the house. In addition, they are usually easier to install and can be placed on top of existing shingles.

The longevity of metal roofing depends on several factors, including the material used and local climate conditions. Copper, zinc, and aluminum roofs last the longest and require very little maintenance. They’re highly durable and can withstand high winds, snow, and corrosive environments. They’re also environmentally friendly and fully recyclable. However, they may be more expensive than other metal roof types and are prone to denting. They can also be susceptible to oil canning, a wavy or rippling appearance that occurs in flat areas of the roof panels due to thermal expansion.

Steel roofs can last up to 60 years and are less costly than some other metal roofing options. They’re durable and resistant to corrosion, but they’re also more prone to dents than other metal roofs and can be difficult to match in color. Like other metal roofs, they can suffer from damage caused by fallen tree branches or hailstorms and need to be inspected regularly for any signs of wear. They’re also susceptible to thermal expansion and contraction, which can cause a wavy or rippling effect known as oil canning.

The pitch, or slope, of the roof also influences longevity. A steeper roof’s surface sheds water more effectively, reducing the risk of pooling and other moisture-related issues. Regular inspections and cleaning can help extend a metal roof’s lifespan, and using protective coatings can make it more resistant to moisture, corrosion, and harmful UV rays. Choosing a metal roof with a Class A fire rating also helps to ensure safety during lightning strikes.

Durability

The upfront cost of metal roofing may be more than traditional shingle options, but these roofs last for decades and reduce the need for frequent repairs or replacement. They also save homeowners money in the long run on energy costs.

Many types of metal roofing can withstand harsh weather conditions, including high winds, heavy snowfall, and hailstorms. However, specific factors like climate and installation techniques determine a metal roof’s longevity. If you live in a location with harsh weather, consider using a thicker gauge metal or opting for a standing seam roof that offers greater durability.

Corrugated and sheet metal roofing can rust if not properly maintained, but coatings that resist corrosion, like Kynar, significantly lengthen the life of the roof. Additionally, regular inspections of the roof and removal of debris can prevent moisture damage and help maintain a clean appearance.

Most experts agree that you should have your roof inspected at least once a year, and this is particularly important with metal roofing. In fact, a professional inspector can spot potential problems that you might not be able to see yourself and recommend the best course of action to avoid serious issues.

One of the most common causes of premature failure in metal roofs is loose fasteners, which can allow water to penetrate the roof and lead to structural damage, leaks, mold or mildew growth, and other interior problems. During an inspection, your roofer will check all fasteners and sealants to ensure they’re intact.

A premium metal roof, such as copper or stainless steel, can last for 75 years or more. These metals are naturally ductile and durable, and their beauty adds to the curb appeal of any home. They’re also highly regarded for their fire-resistant properties and are often used to accent other roofing materials.

For example, a copper roof adds visual interest to a shingle or tile roof and can be used for flashing, gutters, chimney caps, bay windows, and cupolas. Stainless steel is also used as a metal roofing material due to its durability and corrosion resistance, which makes it an excellent choice for residential homes that require a long-lasting and attractive roof.

Energy Efficiency

While metal roofs aren’t new, they are continuing to grow in popularity as more homeowners realize the many energy-related benefits they offer. The ability to reflect the sun’s UV and infrared rays, cool the surface quickly, and provide more efficient temperature regulation inside the home all help lower cooling costs and the overall energy used by the house.

Unlike traditional shingle roofs, metal roofs are able to reflect up to 70% of the sun’s heat and sunlight. They can significantly cut the average homeowner’s energy bills, especially in warm climates. A well-ventilated metal roof can also save money on cooling energy by allowing hot air to escape and promoting the flow of cooler air.

This thermal performance is largely due to a combination of the roof’s reflectance and emissivity characteristics. Both measures of a roofing material’s ability to radiate heat are important for improving a roof’s energy efficiency, and can be evaluated using a solar reflectance index (SRI) test. A roofing system’s SRI rating is based on its ability to reflect the sun’s rays and absorb infrared rays, with a higher score indicating a more reflective roof.

SRI tests can also reveal a metal roof’s ability to emissively release the absorbed heat, or its thermal emittance. A roof’s thermal emittance is based on the percentage of the reflected and emissive characteristics of the roofing materials, along with any additional layers that are added to the structure. A roof’s thermal emittance can be improved by adding insulation and increasing the thickness of the metal roofing.

Another important factor in a metal roof’s energy efficiency is the type of steel it is made from. While there are a number of steel options that can be used in roofing, stainless steel is preferred for its corrosion resistance and durability. A high-quality stainless steel product is designed to last 50 years or more, and requires no maintenance beyond occasional washing with water and a mild detergent.

Although metal roofs require much less maintenance than shingle roofs, they still need regular inspection and care. The best way to protect the investment is to hire a reputable contractor, perform routine maintenance tasks and address any issues as soon as they arise.

Low Maintenance

Metal roofing can last 50 years or more with minimal maintenance or repairs. It also has a wide range of colors and finishes to suit any style, and it is fire resistant and energy efficient. In addition, it can withstand most weather conditions, including hail and heavy winds. However, it is important to select a quality installer and ensure that your roof is properly maintained.

The lifespan of a metal roof depends on the type and thickness of the material, as well as environmental factors. Copper, steel, and zinc are all excellent choices for a long-lasting roof. They are available in a variety of styles and colors, and they can be installed with or without a protective surface coating.

Regular cleaning and inspection can keep metal roofing in top condition. In addition, it is important to use non-cracking sealants on any joints or seams in the roof to prevent water from seeping in. These products are typically inexpensive, and they can be applied easily. Inspecting for rust or corrosion is another important part of regular roof maintenance, and these areas can be repaired quickly to keep the metal in good shape.

A metal roof is more durable than shingles and can withstand damage from falling debris. However, it is still possible for the roof to develop dents or lose its paint finish due to extreme weather conditions. A good roof contractor can advise homeowners on how to protect the metal roof and minimize damage from debris.

Metal roofs are often built to withstand wind gusts of up to 140 miles per hour. While this can result in a slight reduction of the roof’s lifespan, it can help to reduce the amount of maintenance needed.

In addition, a metal roof is not as noisy as a shingle roof when it rains. However, noise can be a problem for some people. An experienced roofer can add proper underlayment and insulation to reduce noise levels.

Although metal roofs require less maintenance than other roofing materials, they should be inspected annually to ensure that all flashing and seams are secure. Failing to do this can lead to roof leaks, so it is crucial to hire a professional roofing contractor to perform this maintenance.

Air Conditioning Repair – Why You Should Service Your AC System Once a Year

Jerry Palmer

While air conditioners last up to 20 years, the first key to their longevity is routine maintenance. Getting your system serviced twice a year will greatly reduce the chance of an unexpected breakdown.

Air Conditioning

During AC servicing, technicians make sure all parts are clean and lubricated. They also repair and replace worn components as needed. Contact Air Conditioning Repair Henderson NV for professional help.

The evaporator coil is the part of the air conditioner that actually cools your home. The job of the evaporator coil is to absorb heat from your home’s air and transfer it outside, but if your evaporator coil is dirty, it might not be able to do its job. A dirty evaporator coil can cause your air conditioning system to overwork, which will wear it out prematurely and lead to more expensive repairs down the road.

One of the most common signs that your evaporator coil is dirty is reduced cooling performance. A dust-coated coil is less effective at absorbing heat from the air, which will make your AC work harder to reach your thermostat setting. In extreme cases, a heavily-clogged coil can freeze over, completely blocking airflow and forcing your air conditioner to turn off.

Another common sign of a dirty evaporator coil is unpleasant odors. Dirty evaporator coils can trap volatile organic compounds, or VOCs, that can be emitted from cleaning products, paints, and furnishings. The blower fan of the AC can then circulate these contaminants throughout your home, causing respiratory problems for allergy sufferers.

In addition to a noticeable decrease in cooling power, a dirty evaporator coil can also reduce your energy efficiency. When the coil is dirty, it can take longer for the air to cool down and for the evaporator coil to return to its normal operating temperature. This will require your AC to run for longer periods of time, resulting in higher energy consumption.

A professional air conditioning technician can safely remove your evaporator coil for cleaning. This process requires the removal of the access panel and use of a shop vac to remove loose debris. Then, your dealer can use a commercial AC cleaner or a mixture of water and detergent to rinse off any remaining dirt from the coil’s fins. They will then return the access panel and wipe down the drain pan to finish up. Your technician should also check and clean the condensate drain to prevent a clogged evaporator coil. Clogged drains can also result in frozen evaporator coils, which will lead to more expensive repair needs in the future.

Dirty Compressor Coil

A dirty condenser coil is a problem that affects your entire air conditioner. The condenser coil, located in the outdoor unit, is responsible for absorbing and releasing heat that your system takes in and circulates to the inside of your home. When the coil becomes dirty, the refrigerant is unable to release the heat it has absorbed. This prevents your air conditioning from achieving the desired temperature set on your thermostat.

The dirt that builds up on the coil serves as a form of insulation and blocks the airflow the coils need to perform their function. This makes the process of absorbing or releasing heat more difficult and cuts down on overall energy efficiency, which can lead to higher power bills. It also puts a strain on the compressor and other components, which can cause premature wear and tear.

Another sign that your air conditioner’s condenser coil is dirty is that it will take longer for the system to cool your home or office. When the coil is clogged, it restricts airflow and can also lead to rattling or buzzing sounds from the unit.

Dirty coils can also cause poor indoor air quality, which could be a major health concern for people suffering from allergies or asthma. The lack of airflow can result in mildew and mold spores circulating inside the HVAC system. The contaminants can then be dispersed throughout your living or working space, making them dangerous for anyone to breathe.

If your AC’s dirty condenser coil is not cleaned quickly, it can cause the compressor to overheat and eventually shut down. When this happens, it will be necessary to repair or replace the entire compressor and possibly the entire system if the damage is severe enough.

Some steps can be taken by the average person to clean the coils, but the most effective way to do so is to hire a professional service technician. These technicians have the knowledge and equipment needed to ensure the coil is properly cleaned and can identify underlying issues that need to be addressed. They can also offer helpful advice regarding preventative maintenance and help you to develop a plan for the future of your air conditioning system.

Damaged Coolant Lines

A damaged or missing coolant line can lead to a refrigerant leak. These lines connect the condenser with the evaporator coil, and they should be intact, tight, and properly sealed. When they aren’t, the air conditioning will struggle to cool the system and your energy bill may soar.

A leaking or damaged cooling line can be due to a variety of factors. A damaged hose, loose hose clamps, or a corroded connection can all cause a loss of refrigerant. Fortunately, you can sometimes fix these issues yourself. However, it’s best to hire a certified HVAC professional to do the work because handling refrigerant is dangerous and requires an EPA-approved Section 608 license.

If your car’s “Low Coolant” light comes on or you find yourself constantly adding coolant, this could indicate a leak in the upper radiator hose. This hose cools the engine and if it fails, your vehicle will overheat.

To check for this, take a look under your car while the engine is running and see if you can spot any coolant dripping out. If you find a puddle, turn off your vehicle and carefully trace the source to the hose or hose connections that need replacing.

In addition to checking the hoses and hose clamps, it’s also a good idea to have your cooling system flushed every 30,000 miles to reduce internal damage. Coolant deteriorates with age and exposure to high temperatures, and the use of abrasive additives can accelerate this process.

Another way to help prevent a coolant leak is by using a quality replacement hose that features electrochemical degradation (ECD) resistance, which decreases the rate at which the hose loses internal pressure. You can test for this by squeezing the hose ends near the connections and if the ends feel softer than the middle or have gaps or channels, your hose is at risk of ECD.

You may be tempted to repair or replace the coolant line yourself, but this isn’t an easy task. Not only will you need to get a Section 608 license, but you’ll need the proper tools to handle refrigerant safely. Your certified AC specialist can provide this service as well as perform the replacement and flushing required to remedy the problem.

Failed Contactor

A failed contactor is one of the most serious AC problems homeowners can face. This is because it affects all the other components of your air conditioning system. Therefore, identifying and resolving contactor issues should be a priority so that minor woes wouldn’t progress to bigger problems in the long run.

A contactor is a mechanical device that opens and closes the power supply lines running through your air conditioner. It is made up of a pair of latching electrical contacts that separate to let in electricity and cut off current to stop the appliance from operating. When it fails, all the components connected to the contactor will be starved of electricity.

The causes of contactor failure can be numerous. They can range from electrical overloading to general wear and tear. Over time, the contacts may develop weld marks that prevent them from opening or closing. In addition, electrical pitting and corrosion can cause the coils to heat up and burn out. High voltage surges can also damage the contactor. Other causes of contactor failure include age and improper maintenance. Dirt, insects, and rodents can chew on the wires, hindering proper functioning.

Common symptoms of a failing contactor include humming or buzzing noises, inability to turn the AC on and off, and ineffective cooling. The buzzing sound is caused by the metal coils and plunger of the contactor rubbing against each other as they move. This wear can cause the metal strips of the contactor to weld together, making them unable to separate.

Another sign of a faulty contactor is frequent circuit breaker trips. This is because the contactor fails to open and close the circuit when necessary, leading to an overflow of electric current. A failed contactor can also produce arcs, which can melt the contacts and other parts of your air conditioning unit. You can identify this problem by the presence of a burnt smell and charring on the contactor’s plastic box. An HVAC technician can replace the contactor to restore its normal function.
