4 Common Air Conditioning Repairs

If your air-conditioning just quit and it’s hot outside, you need help! In most cases, you need a repair professional like Five Star Home Services. However, below, we can help you narrow down the cause and, in some cases, fix it yourself.


If your thermostat is working properly and you have air blowing through your vents, but it’s not cold, we suggest finding your outside condenser to see if it’s working. There are two components there. They include the compressor and the fan motor. With a trained ear, you should be able to hear both of them. The fan should make a whirring noise. The compressor should make a deep buzzing noise like a refrigerator. If you hold a hand above the fan, it should feel warmer than the outside air. If there’s a humming or buzzing coming from the outside of the unit and nothing is turning or blowing, you probably have a bad capacitor. Capacitors are what help the electric motor in your air-conditioner start up and run.


While your home is being cooled, your AC is also dehumidifying it. The process of cooling the air removes moisture at the same time. That moisture is drained to the outside of your house by a PVC drain line. Over time algae and other things can restrict and clog that drain line until it no longer drains like you need it to. If this happens, it can start to back up inside your unit and eventually fill up a secondary drain pan. These secondary drain pans have a safety switch to shut down the system when they are filled. Additionally, the current code requires an “SS2” safety switch which is designed to shut off before any water overflows into the safety pan. Once this safety switch is triggered, several things can happen, depending on how your air conditioner is wired.


The refrigerant you’re using in your air-conditioners is usually R22 (Freon) or 410A (Puron). This is what transfers heat to make your home cool. If the refrigerant levels are too low, the system will struggle to keep up. It can also freeze and ultimately fail to provide cool air to cool your house efficiently, if at all. Most of the time, low refrigerant levels are caused by leaks in the line. Because of this, symptoms are more obvious if you know what to look for. You might also notice your air-conditioner running longer and longer while the temperature becomes harder and harder to achieve. Restoring refrigerant levels to bring your system back to working properly is easy. The hard part is finding the reason your unit is low on refrigerant to begin with. Even though it might be a slow leak, there is refrigerant escaping somehow. Typically, this occurs in the evaporator coil. If the leak is significant, it may be advisable to either replace the entire system (if it’s older) or replace the evaporator coil. If it’s a leak in the refrigerant line, you’re in luck because we can replace these lines without it costing too much.


Both of these parts are located in the outside “condensing unit” of your system. With your A/C system, you should hear both running. If you don’t hear both, or if you have a tripped breaker, or if you hear screeching or grinding, it is possible that either your condenser fan motor or compressor is bad. These motors can fail in three ways typically. In any case, you should give us a call for expert repairs.
