The Most Common Air Conditioner Issues: Causes, Signs, Prevention, and Fixes

Your air conditioner is one of the most critical appliances in your home. It keeps you cool and comfortable during the hot summer months. But what do you do if it starts to malfunction?

Aside from calling in Air Conditioning Installation Repair Hamilton, this blog post will discuss the most common air conditioner issues, their causes, how to prevent these issues from occurring, and possible fixes.

Dirty Air Filters

One of the most common air conditioner issues is dirty air filters. Dirty air filters can cause various problems, including decreased airflow and reduced efficiency. In fact, you'll probably notice that your air conditioner isn't working as well as it used to.

Causes:

A lack of regular maintenance usually causes dirty air filters. When filters aren't cleaned regularly, they can become clogged with dirt, dust, and other debris.

Signs:

If your air conditioner has dirty filters, you'll likely see decreased airflow and reduced efficiency. You may also hear a rattling noise coming from the unit.

Prevention:

The best way to prevent dirty air filters is to clean them regularly. Depending on the type of filter you have, this will typically need to be done every one to three months.

Fixes:

If your air conditioner has dirty filters, the first thing to do is clean them. If you're not comfortable doing this yourself, contact a technician. 

Clogged Condensate Drain

Another common air conditioner issue is a clogged condensate drain. Condensate drains are responsible for draining the water that accumulates on the coil during cooling operations.

If this drain becomes clogged, it can cause several problems, including water leakage and damage to your air conditioner.

Causes:

Clogged condensate drains are typically caused by a lack of regular maintenance or foreign objects blocking the drain.

A clogged condensate drain can cause water to leak inside the unit, damaging it and shortening its lifespan.

Signs:

If your air conditioner has a clogged condensate drain, you'll likely see water leaking from the unit or pooling on the ground around it. You may also hear a gurgling noise coming from the unit.

Prevention:

Cleaning your AC unit frequently is the best way to prevent this issue. Depending on your air conditioner, this will typically need to be done every one to three months.

Fixes:

If your air conditioner has a clogged condensate drain, the first thing to do is clear the blockage. To be safe rather than sorry, contact a technician to help you.

Refrigerant Leaks

A refrigerant leak is another common air conditioner issue. Refrigerant leaks can cause your AC unit to work less efficiently and may even lead to it breaking down completely.

Since the  1990s, the Environmental Protection Agency (EPA) has required all new air conditioners to be equipped with an evaporator coil device.

This device helps prevent refrigerant leaks by catching and storing any refrigerant that may leak from the unit.

Causes:

Refrigerant leaks are usually caused by a problem with the AC unit's coils. If there is a hole or crack in the coils, refrigerant can escape. This causes your air conditioner to work less efficiently and eventually leads to complete failure.

Signs:

If you have a refrigerant leak, you'll likely see one of two things: reduced efficiency or ice on the coils.

Prevention:

The soundest way to prevent a refrigerant leak is to regularly have your AC unit serviced. Depending on the type of unit you have, this will typically need to be done every one to three years.

Fixes:

Refrigerant leaks can be challenging to fix. If you believe your AC unit has a refrigerant leak, you should contact Air conditioner repair Burlington.  

Thermostat Issues

Air conditioners rely on thermostats to regulate the temperature. If your thermostat isn't working correctly, it can cause your AC unit to run constantly or not work at all.

Causes:

There are a few different things that can cause thermostat issues. Common causes include a faulty thermostat, incorrect settings, and wiring problems.

Signs:

If your thermostat isn't working properly, you'll likely see one or more of the following symptoms: air conditioner running constantly, air conditioner not turning on at all, inaccurate temperatures, and erratic behavior.

Prevention:

There are a few things you can do to prevent thermostat issues. First, make sure the thermostat is installed correctly. Second, check the batteries and replace them as needed. Third, always keep the thermostat clean and free of debris.

Fixes:

The good news is there are a few things you can try to fix this issue. First, check the batteries and replace them if necessary.

Second, check the settings to make sure they're correct. Third, clean the thermostat and remove any debris blocking it.

If these things don't work, you'll need to contact a trusted air conditioning repair service such as Canadian Heating and Air for assistance.

Frozen Coils

Coils are an essential part of an air conditioner, and they can freeze for various reasons. When coils freeze, it prevents the AC unit from working properly and can cause long-term damage.

Causes:

There are a few different things that can cause coils to freeze. One common cause is a lack of refrigerants. This can happen if there's a refrigerant leak or if the unit is low on refrigerant. Another common cause is dirty coils.

When coils are covered in dust and dirt, it prevents them from absorbing heat properly. This causes the temperature to drop, which can eventually lead to freezing.

Signs:

You'll know your coils are frozen if you see one or more of the following signs: reduced airflow, hissing or bubbling noises, ice on the coils, and high utility bills.

Prevention:

Keeping your unit clean and well-maintained is the best way to prevent frozen coils. This means regularly cleaning the coils and ensuring there's no dust or dirt build-up. You should also have your AC unit regularly serviced to ensure it has enough refrigerant.

Fixes:

If you have frozen coils, the first thing you need to do is turn off your AC unit. Then, you'll need to thaw the coils. This can be done by turning on the fan or using a hairdryer on low heat. Once the coils are thawed, you can turn your AC unit back on.

If you're unable to thaw the coils, don’t hesitate to call in a professional air conditioner technician. 

Bad Capacitor

A capacitor is an essential part of an AC unit; it helps the unit start and run. If the capacitor has gone bad, it can prevent the AC unit from starting or cause it to run inefficiently.

Causes:

One common cause of a bad capacitor is age. As capacitors get older, they tend to wear out and eventually fail. Another common cause is overloading. If the capacitor is overloaded with too much power, it can short-circuit and go bad.

Signs:

If your capacitor is going bad, you'll likely see one or more of the following signs:

  • air conditioner not turning on at all
  • reduced airflow
  • strange noises

Prevention:

Regrettably, there's not much you can do to prevent a capacitor from going bad. However, you can prolong its life by ensuring your AC unit is clean and well-maintained. This means regularly cleaning the coils and ensuring there's no dust or dirt build-up.

Fixes:

If you have a bad capacitor, you'll need to contact a technician immediately. They can diagnose the problem and replace the capacitor if necessary.
