Air Conditioning Repair

Occasionally, experienced DIYers can perform some basic air conditioner repair tasks such as cleaning the condenser and evaporator coils or clearing the refrigerant line. Learn how to troubleshoot some common AC problems that can be repaired yourself and save yourself the cost of calling a professional.

An evaporator coil that becomes clogged or dirty prevents the AC from absorbing enough heat to cool the air. This can also cause the system to short cycle more often, meaning it turns on and off more than necessary. This wastes energy and accelerates wear and tear on the system’s major components.

The first step to diagnosing this problem is turning off the system and locating the coils. They will be housed inside the air handler and located near the blower fan. It may be helpful to consult the owner’s manual if you have difficulty locating them. Before attempting to clean the coils, make sure you have all your safety gear in place and are familiar with the process.

Once the coils are clogged, they will freeze over and halt airflow to the system. To avoid further damage, you will need to turn the unit off and wait until the ice thaws, which usually takes several hours. During this time, it’s a good idea to have some containers on hand to catch the water that will drip from the coil as it thaws.

When the ice melts, it will drip down the coil and into a drain line. Over time, the dirt in the dripping water will build up and create a clog that will cause the drain to overflow. This can lead to high humidity, moldy odors, and serious health hazards from toxic mold spores. To avoid this issue, homeowners should regularly clean the air filter and inspect the drain line for clogs. Air conditioning service experts can offer maintenance programs that guarantee cleaning of the coils to prevent this problem. They can also clean the aluminum fins to keep them from becoming bent, which reduces airflow and efficiency.

Dirty Compressor Coils

Dirty compressor coils also reduce the ability of your AC system to absorb and dump heat effectively, which makes it harder for your home to reach your preferred temperature. This causes your system to work longer and harder than it should, adding to the overall wear and tear on other components that can eventually lead to a costly air conditioning repair.

You’ll know when your air conditioner needs its coils cleaned if you’re paying close attention to your energy bills. Increasing utility bills are an obvious sign that your AC system is working longer and harder to meet your cooling demands.

In addition to higher energy bills, dirty coils can affect your home’s value and make it harder to sell if you decide to move. Moreover, a dirty coil will reduce your energy efficiency rating and may even prevent you from qualifying for certain tax reductions or benefits that depend on a high home energy efficiency rating.

Your dealer will shut off the power to your outdoor unit and remove the outer cover, allowing you to see the coils. They’ll start by blowing off loose dirt and debris with a shop vac or a soft brush, then using a noncaustic and nonfuming coil cleaner to thoroughly clean them. They’ll spray the cleaner on and rinse it off, making sure to follow the manufacturer’s instructions. They’ll also straighten bent fins if necessary.

If you’re concerned about the cleanliness of your air conditioner coils, it’s a good idea to have them cleaned twice each year. Your dealer can help you decide if this is a good option for your system and recommend the right cleaning method.

Low Coolant Levels

Engine coolant — a mixture of antifreeze and water — helps to pull heat away from the engine as it operates, helping to prevent overheating. Without enough coolant, temperatures under the hood can quickly rise, leading to damage including warped cylinder heads and a blown head gasket that requires expensive repairs.

While some loss of coolant from the reservoir is natural, constant evaporation or leaks from hoses and other components can reduce levels to unsafe levels. Insufficient coolant can also lead to the heater not working correctly, as it needs sufficient coolant to work. Other warning signs of low coolant include a rising temperature gauge, a sweet smell (due to the leaking antifreeze), and reduced fuel efficiency.

The main reason to avoid driving with low engine coolant is that overheating can cause severe and irreparable damage, requiring costly mechanical repairs or even a replacement engine. Coolant is designed to absorb and disperse heat from the engine, so if there isn’t enough of it in the cooling system, the temperature under the hood can rise quickly.

Aside from overheating, other issues that can occur with low engine coolant include a blown head gasket, warped cylinder heads and faulty valves. The cylinder heads are responsible for sealing the combustion chamber, so when they crack from excess heat, they can allow oil to enter the combustion process and cause damage. Additionally, if the coolant is not properly flowing through the system, the water pump can lose lubrication, increasing the risk of failure. The best way to protect against these problems is with regular inspections and maintenance by a professional service. These services can identify potential problems before they become serious and costly.

Failed Contactor

The contactor is an important electrical component that controls the flow of electricity to the compressor. If the contactor wears out, it can lead to a variety of issues. Identifying the issue can help you avoid expensive repairs. A constant clicking noise is a common sign that the contactor is not engaging properly. This can put unnecessary strain on the system, leading to premature wear and tear of other components.

A faulty contactor can also cause your AC unit to short-cycle. A short-cycle is a cycle that occurs when the air conditioner turns on and off repeatedly. This can be frustrating because it will not cool your home effectively.

If you suspect that your contactor is faulty, you should contact a professional HVAC technician for an inspection. They can replace the contactor and restore normal cooling.

Faulty contactors are usually caused by repeated voltage influxes. This can lead to pitting and arcing. If the contactor is not properly sealed, it can weld together and prevent the flow of electricity to the air conditioning system. Other signs of a faulty contactor include a humming sound and an inability to turn the AC off.

To test your AC contactor, shut off the power to your unit. Once the power is off, remove the side cover of the condenser. You will see a number of colorful wires connected to a black rectangle that is positioned vertically. The black rectangle is your air conditioning contactor. Take pictures of the wires and the contactor so you can easily reconnect them when replacing it. Next, use a multimeter to check for continuity between the volt terminals on each side of the contactor.

Failed Blower Motor

As time goes by, your blower motor may start to show signs of wear and tear. Eventually, it won’t be able to keep up with airflow requirements, leading to weak or no airflow through the vents. This is often the first sign of a failing blower motor and it will require an immediate replacement or repair.

Other signs of a failing blower motor include unusual noises such as screeching or squealing. This can indicate loose bearings or other mechanical problems, as well as a burning smell that points to overheating or electrical problems.

A failing blower motor can also lead to intermittent problems such as the fan only operating at certain speeds or the fan never turning on at all. These are more serious issues that should be checked out by a professional to rule out other problems such as a bad thermostat or relay.

Some blower motors use a resistor pack to control speed, while others are equipped with a control module that uses electronics to regulate speed based on sensor input. A resistor pack can fail due to overheating and corrosion, while a control module will need to be diagnosed using a scan tool or multimeter.

Loose or disconnected wiring can also cause blower motor failure, as well as overheating and electrical problems. Some can be fixed by simply reconnecting them or resoldering them, while others will require the use of a multimeter or a wire harness tester to check for power and voltage output. A visual inspection can also reveal any frayed or corroded cables or connectors that need to be replaced.

Roofing contractors have years of experience in handling the installation, repair, replacement, inspection, and maintenance of commercial and residential roofs. They can also handle other exterior projects, such as windows and sidings. Some roofing specialists may even specialize in particular kinds of roofing, such as flat or slate roofs.

It is important to find a roofing contractor who is licensed and insured. This protects you from liability if something goes wrong during the project. The best way to ensure this is by asking for proof of insurance before hiring a company. Make sure to ask for both workers’ compensation and general liability insurance. In addition, you should ask about their workmanship warranty. A standard workmanship warranty runs between five and ten years.

Moreover, a quality roofing expert will not try to cut corners by using cheaper materials. Instead, they will use high-quality products that last longer and improve the overall appearance of your home. Choosing the right roofing contractor will prevent future problems with your roof and save you money in the long run.

Experience

A roofing contractor’s experience plays a vital role in the quality of work they perform. It enables them to deliver exceptional projects, as they know how to tackle various aspects of a roof construction, repair and replacement project with ease. Their extensive knowledge translates to better choices of materials and installation techniques, resulting in structurally sound and durable roofs that last for years to come.

A good roofing contractor should be able to demonstrate their previous work through a portfolio of photographs, as well as provide references that can testify to the quality of their workmanship. If a contractor is reluctant to do so, it is a red flag and you should look elsewhere for a more trustworthy service provider.

Experienced contractors also understand the importance of observing safety protocols, and they ensure that their crews adhere to these guidelines at all times. This enhances the overall safety of the entire project, as it minimizes the risk of accidents or injuries.

Roofing is an intensely physical job, and it requires that contractors be able to stand on ladders or scaffolding for long periods of time while working with hand tools. Moreover, they must be comfortable working in extreme weather conditions and navigating debris on rooftops. Moreover, roofing contractors must be familiar with different types of roofing, including flat and pitched roofs, as they may need to do repairs on these surfaces in addition to installing new ones.

It is important for homeowners to ask potential roofing contractors for proof of their insurance accreditation and licensing – they should be willing to share copies of these documents in writing. It is also a good idea to check their references and review their reputation on sites like Reddit and Trustpilot before hiring them.

Licensing

As the construction industry continues to evolve into one of the most tightly regulated industries in the nation, it’s important that homeowners take the time to ensure that their roofing contractors are properly licensed for the work they perform. This is especially true given that many states have varying licensing requirements at the state, county, and municipal level.

To begin, find the local municipality responsible for contractor licensing in your area. Many maintain official websites with dedicated sections that offer detailed information on specific licensing regulations. Additionally, most will have an online search tool that allows you to simply type in the roofing contractor’s business name and provide you with any relevant information.

In Alaska, for example, anyone doing residential or commercial roofing contractor work must be licensed by each of the following entities: The Department of Commerce, Community and Economic Development; the Division of Corporations, Business and Professional Licensing; and the State Construction Industry Licensing Board. The process for obtaining a license includes pre-approval, passing a trade exam, and providing Proof of insurance and worker’s compensation insurance.

In New York City, for instance, any roofing contractor who wants to do work in the city must first be registered with the NYC Department of Consumer Affairs. In order to register, a roofing contractor must pass a general business and home improvement trade exam. They must also provide Proof of insurance, and post a $15,000 surety bond.

Insurance

When you are a roofing contractor, your insurance coverage is crucial. You must have workers’ compensation and general liability insurance. These policies protect you and your employees in case of an accident on the job or damage to a customer’s property. In addition, you may also want to get professional liability insurance. This policy covers your business in the event that you make a mistake during a roofing job or give bad advice to a client.

In addition, commercial umbrella insurance is often a good choice for roofers because it provides additional liability protection in the event that your standard insurance coverage isn’t sufficient. This type of insurance typically offers higher limits and more coverage than regular business policies. It is worth comparing quotes from multiple insurers to find the best deal.

Another essential insurance for roofing contractors is commercial auto insurance, which covers the vehicles that you and your employees use for work. This coverage will often exclude any personal vehicles, so you’ll need to get a separate policy for them. You should also consider getting a tool and equipment policy, which will provide protection for any specialized tools that you own or rent. You can also add a floater to your BOP, which will cover any equipment that is left in your cars or in storage spaces.

If you regularly work at different locations, it might be a good idea to get inland marine insurance. This type of policy will cover equipment and supplies that are in transit between jobs. It can be particularly helpful if you need to ship high-value equipment, such as large construction machinery or premium shingles. You can also get a builder’s risk insurance policy, which will protect buildings and structures while they are under construction.

Warranty

A solid warranty from a roofing contractor offers homeowners peace of mind. It mitigates risks that may result from poor workmanship or a defective product. It also helps with unforeseen expenses and other concerns that might arise from your roof, such as leaks caused by storm damage or a tree falling on the roof.

Most manufacturers offer a manufacturer warranty that covers material defects for up to 30 years, with some offering lifetime warranties. However, these are typically only applicable to shingles and other materials. Other components such as underlayment, ventilation products, and flashing won’t be covered by standard manufacturer warranties. Therefore, you will need to look for a contractor that offers a workmanship warranty.

This type of warranty guarantees that a roofing contractor will remedy any errors that occur during the installation process for up to one or two years. Moreover, it will cover labor costs and materials for any repairs that are needed to fix the issue. However, it is important to note that the workmanship warranty does not provide coverage against weather-related damages or other problems unrelated to the installation.

Additionally, some contractors stipulate that their warranty remains intact if the building owner hires them to carry out maintenance inspections on the roof during the duration of the warranty period. This is a practice that many consider to be extortion.

Choosing a roofing contractor with both a manufacture and a workmanship warranty will offer you the best protection for your investment. These types of warranties offer robust and lasting coverage that will give you a good return on your investment. In addition, they can help enhance your home’s resale value and ensure that you have peace of mind as you enjoy your new roof.
