Top 8 Most Common Air Conditioner Problems

Top 8 Most Common Air Conditioner Problems

It always seems to be in the most inconvenient of times that you notice air conditioner problems. Whether it be from faulty equipment or poor maintenance when your air conditioner is struggling to provide cool air in the Florida heat you want to find out what’s causing it as soon as possible. Here are some common reasons why your air conditioner is having issues.

Dirty Air Filter

Changing the air filter is a simple task to maintain your air conditioner, but is one of the most common causes of AC problems. Changing the air filter on a monthly basis will ensure that the air is being cooled effectively and will keep your system running efficiently.

Refrigerant Leak

Refrigerant leaks are often overlooked if you are not familiar with air conditioners. If your air conditioner is low on refrigerant it was either undercharged at installation or there is a leak. Replacing the refrigerant if there is a leak will only cause your system to freeze and stop working. If there isn’t a leak then the manufacturer’s recommended amount of refrigerant should be followed to recharge the refrigerant. A trained technician should be called to fix either of these problems to ensure that the system is fixed correctly otherwise other problems will surface.

Disconnected Air Ducts

If the air ducts are not connected properly or are disconnected then air could be escaping under the house or into the walls. Rusty air ducts could also be causing air to escape. Air duct cleaning should be performed to make sure that the air ducts in your AC system are connected and functioning efficiently. Old or leaking air ducts can easily be replaced by a trained professional as well.

Clogged AC Drain Line

With all the rain here in Florida, blocked drains happen quite frequently. When drains are blocked air isn’t able to flow in our out of the system which causes it to stop working. When it is humid outside you can check the condensate drain to make sure it is draining properly. Learn how to unclog a clogged drain line yourself.

Worn-Out AC Compressor

When the compressor is worn, the refrigerant isn’t being pumped through the unit to produce cool air. If your A/C is blowing warm air, replacing the compressor could fix the problem. Schedule a consultation and a technician can analyze whether your compressor is working efficiently or not.

Blocked AC Sensor

Behind the control panel of most units, there is a thermostat sensor that measures the temperature of air entering the evaporator coil. Sometimes this sensor gets knocked out of place or stops working which causes your A/C to run constantly or uncontrollably. You can check the position of the sensor by the coil to see if it is being blocked. It should be near the coil but not touching the coil.

Wrong Thermostat Setting

If you don’t have a window unit your thermostat is most likely programmable so that you can raise the air when you leave and have it lower when you are home. Make sure to keep your thermostat on ‘auto’ not ‘on’ so that only cool air gets circulated around the house. Keep in mind that for every degree you raise your thermostat, you save 3 percent on utilities!

Dirty Evaporator Coils

Condenser coils play an important role in your air conditioner. Coils remove the heat that’s being extracted from your home and move it outside. Since they are located outside, it is easy for dirt and debris to collect over time. Dirty coils could cause your home to not cool effectively, warm air to come out of your air vents, and spike your utility bill. Annual maintenance on your air conditioner will ensure that the coils get cleaned properly and regularly.
