Common air conditioner problems

There are a quite few common air conditioner problems that you may experience from time to time. These include the air conditioning unit freezing up, the compressor shutting off, and water leaking from the unit.

We will go over the most common air conditioner problems that you might face, and when you do, call Crisp Climate Control for your Cleburne, Texas HVAC repair needs.

Refrigerant leaks

Here is a common one that is typically gradual. The air conditioning unit will gradually lose its ability to cool the room, likely because of refrigerant leaks. If this is the problem, you may need to recharge the system and have the refrigerant leak located in your air conditioner system.

Compressor issues

Another problem that happens is the air conditioning compressor going out. You may notice a rattling or clicking sound coming from the unit. This is usually a bearing going out in the compressor motor, and it can happen suddenly, so if you hear this noise, call right away! A constantly running compressor with no refrigerant charge could also signify a bad compressor.

Frozen Evaporator coil

Another problem is the evaporator coils (the inside part of the air conditioner) freezing up. This can be due to issues such as a low refrigerant charge, a dirty filter, a blower motor going out, or a thermostat set too low. If the evaporator coil is frozen, turn the system off and call for service.

Frozen condenser coils

This is when the condenser coils (the outside part of air conditioners) in your HVAC become frozen, usually due to a unit constantly running with a low refrigerant charge from refrigerant leaks. It could also be a condenser fan motor problem. If you notice this, turn off the system and call for service.

Sensor problem

Here is another common air conditioner problem, and it can be a little difficult to diagnose. The air conditioner unit may not turn on automatically due to a sensor issue. It could be that the sensing switch has gone bad, or there is an issue with the thermostat wires.

The air conditioner doesn’t turn on

This could be a multitude of problems. There may be no power getting to the unit, the breaker has been tripped, or there is a bad switch. Check these things before calling for service.

Water leaks

Another common air conditioner problem is a water leak. If you notice puddles or a pool of water under the air conditioner unit, it may have a refrigerant leak and need to be recharged, or it could have a water leak from the drain pan. It is also possible that you have a clogged drain line.

Dirty air filter

Dirty air filters have many possible consequences, including increased electricity usage and declining air conditioning performance. A dirty air filter can also cause your indoor coil to become dirty, which will decrease the efficiency of the air conditioner unit. This also reduces its ability to filter the air, causing a low indoor air quality. If you have a dirty air filter, replace it as soon as possible!

Drainage problem

Drainpipes from the air conditioner can be contaminated with sediment, bacteria, or dirt. If your drainage system is clogged, this can cause water leakage and other problems. Inspect your drainage regularly and clean it out as needed to prevent these issues.

Electric control failure

This is another problem that can be difficult to diagnose. The AC unit may stop working altogether or turn on and off repeatedly. If this is the problem, the best thing to do is call for service.

Air conditioner not blowing cold air

If the air conditioner is not blowing cold air, it could be a problem with the compressor, the fan, or the thermostatic control. Shut it off; there is no reason to have it blowing hot air, then call for service.

Thermostat problems

If the thermostat is not working correctly, it can cause the air conditioning system cannot turn on or blow warm air. The best way to fix this problem is to replace the thermostat.

Air conditioner making noises

There are a few different noises that your air conditioner can make, and knowing the cause of each noise can help you troubleshoot the problem. Some of the most common AC noises are: rattling, clicking, humming, and whining. If you are experiencing any of these noises, call for service!

Inadequate maintenance

This is probably the most significant cause of problems in Air Conditioners. If the AC unit is not correctly maintained, it will not run efficiently and may break down. Make sure to change the air filters regularly, clean the drainage system, and inspect all AC unit parts for damage or wear. In addition, you should have a licensed air conditioning repair expert look over your unit and perform HVAC preventative maintenance at least once a year to ensure it keeps running correctly.
