5 Most Common AC Unit Problems

February 13, 2019


During spring and summer in Murrieta, you’ll be using your AC unit a lot more to avoid those blistering hot days or keep warm during the cold nights. There are a variety of common AC unit problems that occur during the spring and summer months because of the wear and tear your AC unit goes through. At ProFlo, we offer services for all types of AC repair needs, so we’ve seen our fair share of air conditioning problems. Here are some of the most common AC unit problems that your unit might have.

Leaking Due to Dirty Air Filter

It’s common for homeowners to forget to switch their AC unit’s air filters; however, it’s one of the most important steps to maintaining the longevity of your air conditioning system. A dirty air filter restricts efficient airflow over the evaporator coils, causing them to freeze over. As the frozen coils melt, the excess moisture trickles into the condensate pan and leads to an overflow of water and cause leaks in your AC unit.

AC Capacitor is Faulty

An AC capacitor is a part that sends energy to the AC unit motor that powers up your air conditioning system. This small cylindrical mechanism allows your AC unit to run continuously and function properly. To check if you have a faulty AC capacitor or not, the first thing you would need to rule out is a dirty air filter. If your air filter looks dirty and is not letting airflow through, you’ll need to replace it before you can check your capacitor. Some symptoms of a faulty AC capacitor include: your AC blowing hot air, humming sounds from the AC unit, and a delayed response to turning on. If you’re experiencing any of these symptoms, it’s more than likely that the capacitor has gone bad and you should give us a call here at ProFlo so we can diagnose and change out the capacitor.

Low Refrigerant

Refrigerant, also known as Freon/coolant, is the cooling agent that creates the cold air within your air conditioning system. Low refrigerant levels could imply some type of leak or problem within your AC refrigerant system, which can eventually lead to complications and temperature fluctuations. These reduced levels result in a low amount of pressure in your AC unit, which causes your evaporator coils to freeze over and eventually create a leak. Make sure to check for leaks before adding in more refrigerant to your air conditioning unit as it can cause further issues.

AC Unit Blowing Hot Air

If you notice that your air conditioner is blowing hot air, the most likely reason is your AC unit has a dirty air filter or debris restricting air flow – causing inefficient flow problems through your system. Be sure to check your air filters and AC unit for any blockage or debris surrounding them. Any obstruction can block your air flow and cause hot air to come out of your AC unit instead of cool. If you’ve checked your air filter and unit, but can’t figure out what the issue is, give ProFlo a call, and we’ll diagnose your problem right away.

Compressor Won’t Run

Your compressor plays a vital role in your HVAC system, as a compressor condenses the refrigerant in order to move it through your AC system. If you’re experiencing issues with your compressor, it could indicate that there is a burned wire, defective thermostat, broken valves, or a faulty capacitor. Since your HVAC compressor has many parts, it may be difficult to check to see if all the surrounding parts are functioning correctly. Be sure to contact ProFlo, your local Murrieta HVAC technician, for further inspection.
