It always seems like your AC unit will breakdown on the hottest day of the year, exactly when you need it most. This is no coincidence. Your air conditioning unit will be most susceptible to failure when it is most used.
The trouble is we don’t often think about it until it has already broken down. Here are four common reasons your AC is failing this season.
1. The Thermostat Isn’t Working Properly
If your AC unit cannot detect the correct temperature it likely won’t turn on or off at the right comfort level. If your air conditioner is cycling on and off at seemingly odd times and temperatures it is a good sign your unit’s thermostat needs to be replaced.
To resolve this try replacing the batteries on the thermostat. This is a simple step that can quickly solve this issue.
You should also try and clean it. Dust and dirt can build up quickly and impact your thermostat’s performance. Use a clean paintbrush or similar tool to gently brush the inside of the thermostat.
2. Check Your Circuit Breaker or Fuse
If your air conditioning unit stops working, one of the first things you should check is the circuit breaker and fuse. There is an important trick to this though. Your AC unit will likely need 15 minutes to cool down after resetting the power.
If the unit will not restart after a full 15 minutes you may have triggered a high limit switch and you will now need to call a technician.
3. Your Evaporator Coil is Frozen
A frozen evaporator coil is a common issue that may be causing your AC unit to fail. This is caused by built-up dust and dirt in your ductwork. This leads to airflow backups in your cooling unit.
If your unit is dripping water this is an indication that the evaporator coil is frozen. Check for frost and ice around the coil.
To remedy this make sure to keep your ducts and air filters clean. You will need to replace the ducts and filters if this problem persists.
4. You’re AC Unit is Low on Refrigerant
If your AC unit is not producing cold air or is not operating correctly you will need to check your unit’s refrigerant. The refrigerant is the cooling agent inside your AC unit. If your unit is low or leaking refrigerant it will not cool the air properly.
Refrigerant is harmful to the environment and needs to be handled with care. If you have a leak or another issue with your refrigerant you need to contact a licensed technician for immediate repairs.
