Common Air Conditioning Problems
The most common problem with the simplest solution usually doesn’t require any AC repair at all. It’s not uncommon for us to get a call about a broken air conditioning unit and, upon inspection, we discover that the filter hasn’t been changed out in a long time and is completely blocking airflow because of all the dust and dirt buildup. Regular filter changes are necessary to keep your AC system running efficiently.
The sensor on the thermostat control sends a signal to the air conditioner with the registered temperature. If the sensor goes bad or has been dislodged from its space, it may not be able to correctly register the inside temperature. This discrepancy can cause the AC to run too much or not enough.
Sometimes, the problem with your AC is that there are not adequate electrical supplies to support the power needed to run the unit and all the other machines or devices in the house. If your AC won’t turn on, or turns off unexpectedly, it could be that you’ve tripped your breaker.
Your air conditioner runs on refrigerant. It’s the liquid chemical that helps cool the air to the desired temperature. If the refrigerant levels get too low, then your AC will not be able to keep up with the cooling demand. Also, low levels indicate that there is likely a leak in the system. Simply adding more chemical won’t fix the problem. The leak needs to be found before the AC repair can take place.
The contactor is responsible for sending electrical power to the air conditioner from the thermostat. It is much like the old-time operators that a person would call to then be connected with a party on the other end of the phone line. The contactor starts to wear out and causes pitting when it’s been exposed to too much heat or incorrect voltage due to loose wires. If left this way, the contactor will eventually be unable to make contact with the terminals to get them the voltage needed to power the system.
Along the same lines with not having enough amps to support the air conditioner, it could be that the electrical wires servicing the unit are loose, damaged, or incorrectly installed. Our service technicians will be able to let you know if the wiring is faulty.
