There’s nothing worse than your air conditioning unit malfunctioning on a hot summer day. Luckily, there are only a handful of possible problems, and you can easily learn to identify the root cause. By keeping an eye out for the following, you’ll be able to correctly identify problem areas and converse more technically with your AC Repair professionals.
1. The AC doesn’t turn on
There may be a few reasons why your AC unit isn’t turning on. One of the main causes is a broken or inappropriately placed thermostat. Evaluate whether the sensor is broken or if the thermostat is placed in a much hotter or colder place than the space you’re attempting to cool. Another reason why your AC won’t turn on could be a broken circuit, a tripped breaker, or a faulty relay switch. If resetting or flipping the breaker doesn’t fix the problem, call the professionals as soon as possible to address electrical issues.
2. The AC is on, but isn’t cooling
Again, there is a myriad of reasons why your AC may not be cooling effectively. If your condenser coil is stalling, then resetting a breaker may work. If that doesn’t work it could mean there is not enough refrigerant in your system. If your levels are low, the culprit is probably a leak. In that case, a professional is needed to locate and repair the leaks and recharge the system with new refrigerant.
3. Airflow is restricted
The culprit may be as simple as a dirty filter, but can be as complicated as blockages in your outdoor unit. Make sure your filters are changed every 30-60 days depending on the frequency of AC usage and how many people and pets are in the household. Outdoor units should be kept clear of any encroaching foliage and debris. Additionally, if you are having problems with airflow, your condensation drains may be blocked with dirt, insects or even mildew and debris. Identify the source of the problem immediately!
4. The AC Unit makes irregular noises
Check your air-handlers! If an old model is motor-driven, a belt connecting the motor to the blower may have slipped and you may hear some squealing. A dirty compressor may also be to blame for a louder than normal unit. If a unit is poorly maintained, debris and frequent use will wear down the compressor and fans and cause them to fail prematurely.
5. Utility bills are higher than normal
A combination of electrical control failure problems, sensor issues, refrigerant leakage, and improper maintenance can lead to your AC not functioning properly.
