Common AC Problems and How to Fix Them

Your AC unit is consuming more energy than usual, which might be an issue. First, check if you accidentally set the thermostat to "heat" instead of "cool."

Some things, including dirty air filters, incorrect mode selection, low refrigerant, and a faulty motor, can cause this problem.

Frozen Coils

Frozen coils are one of the most common AC issues and, if not corrected, can cause even larger problems. When the evaporator coil becomes frozen, the air conditioner can no longer absorb heat from the home and blow cold air. This mechanical problem requires a professional to repair and may require parts replacement.

To fix the problem, turn off the AC, turn on the fan (usually "auto"), and let the ice melt. Then, check the evaporator coil for any dirt or debris that needs to be cleaned and the ductwork for any obstructions or disconnections. If the problem persists, low refrigerant levels or a malfunctioning defrost cycle could be to blame. The best way to prevent this is to perform routine maintenance and implement a regular schedule of changing the air filter.

Dirty Air Filter

A dirty air filter impedes unrestricted airflow through your system, which makes it harder for the unit to remove heat from your home. Over time, this can lead to iced coils and frozen condensate.

If you turn on your AC and hear squealing, rattling, or grinding sounds, it's time to call in an Arvada AC Repair. These noises typically indicate a bigger problem that you should avoid trying to figure out yourself.

If your AC is blowing cold air but not as strong as it used to, you may have a thermostat issue, a refrigerant leak, or a compressor problem. A technician can check your thermostat settings and replace the air filter if necessary. They can also fix leaking ducts using foil tape or mastic air duct sealant (the latter is preferred because it lasts longer).

Thermostat Issues

If your AC is working fine, but it takes a while to cool down your home, you may have a problem with your thermostat. Dirt, lint, and dust can build up inside the thermostat and restrict airflow. Try removing the cover of your thermostat to wipe it clean. Consult an HVAC professional for a more technical solution if something else is needed.

If you hear strange sounds from your AC, like a whine or rattling noise, it could indicate a problem with the capacitor. This component needs a lot of power to start the AC, so it can easily overheat if there are power fluctuations.

Before fixing this, ensure the unit's circuit breaker is off. This can be dangerous, so it's best to leave this task to a trained professional.

Water Leaks

The AC cools the air by blowing warm indoor air over evaporator coils. As the refrigerant absorbs heat from the air, it turns into a liquid and slides down the evaporator coil into a drain pan. The drain pan is pumped away through the condensate drain line, a sealed tube that takes water outside your home.

If this pipe gets clogged or damaged, it can cause a flood and water damage. This problem usually requires professional AC repair, as the refrigerant should be handled only by trained professionals.

If you notice a water leak, shut down the AC system and remove the power cable from the electrical socket. Open the front panel of the indoor unit by removing screws and a plastic cover.

Electrical Issues

Nothing is more frustrating than turning on your air conditioning only to find it's not blowing cold air. Some issues, including dirty or clogged air filters, thermostat settings, leaking ducts, low refrigerant levels, and more, could cause this issue.

If you are experiencing this issue, check your breaker switch to ensure it hasn't flipped. You may also want to try lowering your thermostat a few degrees and see if that helps.

Electrical issues can also occur due to daily wear and tear or faulty wiring or fuses. It is important to have any electrical issues dealt with by a professional. Otherwise, they can lead to expensive repair costs or even a fire.
