Common AC Repairs You Can Do Yourself

Your air conditioning system has several parts essential to keeping your home cool. If any of these components break down, the machine will not be able to produce cool air.

AC Repairs

During maintenance visits, technicians check the condition of these components and repair or replace them as needed. Some of these repairs can be done in under an hour. Contact AC Repair Encino for professional help.

It’s the hottest part of summer, and your AC compressor has suddenly stopped working. Your home is heating up, the kids are cranky and you’re handing out glasses of cold lemonade as fast as you can. There are some common causes of this problem that you may be able to address yourself:

Check the power cord and ensure it is properly connected and turned on. Inspect the unit for dirt and debris that may be blocking the fan. If there is a blockage, you should be able to clear it. It’s also a good idea to ensure the air cabin filter is clean, as this can affect air flow and cooling.

If you’ve gone through all the troubleshooting steps and your AC compressor is still not starting, there may be a problem with the clutch or bearings within the unit. If this is the case it is usually best to replace the compressor rather than attempt a repair.

Another possibility is a refrigerant leak. A leak can cause the system to overwork and lead to premature failure. This can be caused by poor maintenance or overuse. A professional can help determine the severity of a leak and recommend an appropriate repair.

It’s also important to keep in mind that some older motors simply cannot be repaired and will need to be replaced. It’s not always easy to decide between repair and replacement, but a professional can provide valuable data that helps bring the costs into focus.

To start your compressor, first make sure it’s unplugged and any capacitors are discharged. Next, find the electrical connector on the compressor and carefully disconnect it. It’s a good idea to mark where each wire leads so you can reconnect them easily. Finally, disconnect the refrigerant lines from the compressor. These are usually located in the engine compartment near the firewall. After you’ve removed the line, you should be able to see the compressor and its components more clearly. It’s also a good idea at this point to disconnect the compressor’s pulley so it doesn’t get damaged during the repair process.

Repairing the Blower Motor

The blower motor is a vital part of the air heating and cooling system. However, many people don’t pay attention to it until something goes wrong. Fortunately, it’s not difficult for an AC repair shop to determine and fix the problem.

The first thing to look for is a lack of airflow from the vents in your home. While the problem may be rooted in a variety of reasons, like clogged filters or ductwork, it is often caused by problems with your blower motor. A faulty fan can cause the system to work overtime, straining the system’s motor and leading to overheating. In addition, a broken blower motor will not blow conditioned air into your home, leaving you with cold and uncomfortable rooms.

You may also notice other signs that your blower motor is having problems. These include odd noises such as clanking and rattling. These sounds can indicate that a part is loose or that debris is trapped in the motor. Additionally, sudden spikes in energy bills are another sign that something is wrong with your system.

If you do decide that your blower motor is having issues, there are several things that can be done to correct the problem. A professional can clean the moving parts in your unit to help remove any clogs. Alternatively, they can replace the blower motor altogether. However, replacing the blower motor is generally more expensive and will require additional labor charges.

Another option is to buy a new blower resistor. This is a small component that controls the speed of the blower motor. It’s easy for an experienced technician to replace it by simply turning off the power to the unit, draining its capacitors and then removing the old resistor and installing a new one. This is a simple repair that shouldn’t take more than an hour, meaning you won’t be without your air conditioning for too long. It is important to only purchase genuine blower motors from reputable suppliers and never try to save money by purchasing a knockoff model. These models may not fit your vehicle correctly and can cause damage to other parts of the system.

Repairing the Coils and Fins

One of the most common AC repair issues is a failing capacitor. Capacitors get a lot of abuse as they switch on and off to power different parts of your air conditioner. They can also wear out over time, which makes them less effective at doing their job. A trained HVAC technician will be able to diagnose this issue and replace the capacitor, which should only take about an hour in most cases.

Another common problem is a frozen evaporator coil. This can occur for a variety of reasons, including dirty air filters and blocked return air ducts. A frozen coil can also be caused by low refrigerant levels, which is why it’s important to have the system checked for proper refrigerant levels when you notice any cooling problems.

Damaged AC coils can be a major problem for any home or business, resulting in high energy bills and reduced air flow through vents. In addition to causing discomfort, these issues can also lead to costly repairs and replacements of other system components. Preventive maintenance tips include regularly cleaning or replacing the air filter, scheduling regular professional tune-ups and checking refrigerant levels frequently.

Corrosion and hail-damaged condenser fins can also be a big issue for your AC. These thin metal fins are easily bent by weather or debris, reducing the efficiency of your unit and making it difficult for air to pass through the coil. These problems are usually easy to fix at home, however, as all you need to do is use a fin comb and a blower to straighten the coils and clean them.

It’s always best to have a qualified technician handle the more serious issues when your AC isn’t working properly, but these simple repairs can give you peace of mind until you can have a pro look at the problem. They’ll be able to help you select the right part for your particular unit and get it installed quickly and correctly, giving you years of cooling comfort.

Repairing the Contactor

One of the most common AC repairs is replacing the contactor. This is a type of electrical component switch that sends energy to the fan and compressor of the outer condensing unit by sending a signal to a magnetic coil. Over time, the metal contacts of this circuit wear out from frequent use. When this happens, your AC may start to emit a humming or chattering noise. The repair itself is fairly simple and doesn’t require any complex machinery.

Often, all your technician needs to do is open the access panel that covers this part of the AC unit, turn off the power to the thermostat and disconnects, and then replace the contactor. This is another easy fix that shouldn’t take more than an hour.

While your service technician is doing this, you can ask him to check your air vents for obstructions. Furniture, toys, and drapes can block airflow through return air vents in your home, so make sure all of them are clear. It’s also a good idea to check the unit for signs of wildlife. Sometimes birds or small critters build homes inside the unit, and they can cause damage if left unattended.

When it comes to choosing an AC repair shop, you want to look for a company that offers a variety of services. Whether you need a basic repair or something more involved, such as replacing the capacitors or fan motor, you should choose a company that has experienced technicians who know what they are doing. They will be able to diagnose problems quickly and accurately, and will be able to complete the repairs efficiently.

You should also pay attention to how convenient the company is. For example, do they offer emergency service? Do they have a number that you can call 24 hours a day, or do they only offer normal business hours? Finally, you should also consider the pricing options. Some companies may have lower prices than others, but they should all be transparent about their fees and should provide a detailed breakdown of the costs involved in each repair.
