When your air conditioner isn’t working properly, it won’t take long for your home to become unbearably warm. Thankfully, it’s easy to solve some of the most common AC repair issues on your own!
At the very least, you can troubleshoot the issue to provide more details to the repair technician so they can find a solution quickly.
Addressing the Most Common Air Conditioning Problems
Many of the most common AC repair issues stem from a lack of maintenance. Regular air filter replacement (usually every 60 to 90 days) and an annual professional service visit can prevent many of the following common AC repair issues.
With that in mind, here’s what to do about specific air conditioner concerns.
No Power
A tripped circuit breaker is the most likely reason an air conditioner won’t turn on. If there is a surge of electricity on that circuit, the breaker will trip and cut the power. If it happens repeatedly, something is wrong within the electrical system.
Thermostat problems and electrical faults within the air conditioner, including loose wires, worn contactors, and a faulty capacitor, can also keep the unit from turning on. These also require professional repairs.
Blowing Warm Air
If your air conditioner blows warm air, make sure the thermostat isn’t accidentally set to heat. If that’s not the problem, the issue could be a dirty air filter or obstruction in the ducts causing airflow issues that lead to uneven temperatures.
If you notice a hissing sound, a sweet smell coming from the unit, or bright-colored stains around the unit, a refrigerant leak is the culprit. Refrigerant leaks can eventually cause compressor failure, so addressing them immediately is critical to preventing a more expensive issue.
Strange Noises
If you hear anything unusual when the air conditioner is running, check the outdoor unit for sticks or other debris caught in the grill. Loose ductwork can also cause rattling noises.
Other noises, like squealing and grinding, indicate mechanical issues. Squealing usually means a problem with a belt, like excessive wear or misalignment, while grinding noises indicate trouble with motor bearings.
Frozen Coils
Ice on the air conditioner coils or copper lines is never a good sign, as it means your air conditioner is working too hard to cool your home. A dirty air filter or coils, an obstruction in the system, or mechanical failures within the blower and condenser can all cause excessive wear and tear that eventually lead to total failure.
If changing the filter doesn’t solve the problem, have an HVAC professional investigate.
Water Leaks
Water leaking from the air conditioner usually indicates a clog in the drain line or a problem with the condensate pump. You may be able to clear the blockage in the drain line using a wet-dry vacuum.
