Top 10 Air Conditioner Maintenance Issues (and How to Fix Them!)

Any time your air conditioner breaks, it can be very stressful – AC repair can be expensive, and they always seem to break down at the worst possible time. Fortunately, many air conditioner problems are very common and, with a little elbow grease, can be solved pretty easily. For all the rest, there’s All Seasons Heating & Cooling!

What is your air conditioner problem?

My compressor (outdoor unit) doesn’t even come on

This is a common problem that many people face at the beginning of every cooling season. The first thing to do is check if there is power going to the unit. First, check the disconnect switch to make sure it is in the ON position. If it is, and there is still no power, make sure the breaker is working and the wire is not burned at the disconnect switch. If these are not the problems, you may have a defective contactor, thermostat or transformer. An electrician or HVAC technician will be able to diagnose these symptoms and tell you what the best course of action would be.

My circuit breaker trips when the unit turns on

If your circuit breaker trips every time your compressor cycles on, you may just have a weak circuit breaker. If not, the problem probably lies with the air conditioner itself – you either have a grounded compressor, a shorted condenser fan or a defective contactor.

My air conditioner runs much more loudly than usual

If your air conditioner makes a lot of noise when it runs, there may be a problem with your fan belt. Usually this problem is simple – the belt has become dislodged from its track and it just needs to be popped back on. While a loose fan belt seems like a minor issue at first (and, indeed, it is), if you ignore the problem for too long it can lead to extremely loud noises coming from your fan and can potentially cause severe damage to the fan belt.

My AC fan runs but the compressor does not

If the fan runs but the compressor doesn’t, your problem may be a burned wire at the compressor. If not, you may have a defective start or run capacitor. If all else fails, check your refrigerant charge and clean your condenser coil – these might be the source of your problem.

My air conditioner coil is frozen

Frozen AC coils can seriously hamper the operation of your air conditioner. Fortunately, it’s pretty easy to prevent your AC from freezing – in fact, 9 times out of 10 the problem can be avoided simply by changing your air filters every month! If this isn’t enough to solve the issue, your problem may be caused by a dirty evaporator, or you might just be low on refrigerant.

My AC is Leaking Inside My House

An air conditioner that leaks into your house can potentially lead to serious problems, including mold growth and water damage. If your air conditioner is leaky, check the drain pan and make sure it is not rusted over. Then, make sure there are no blockages in the drain itself that are keeping all the water from finding its way into said drain pan. If the drain is clear, see above – your air conditioner may be leaking as a result of a frozen compressor.

My thermostat is not holding the proper temperature

If your thermostat is not holding the temperature the way it should be, it could simply be the result of defective calibration with your thermostat. Try to recalibrate the device and see if that fixes the problem – if not, you may need to replace your programmable thermostat (fortunately, they’re not expensive).

My outdoor unit runs but the fan doesn’t

If your compressor runs, but the fan doesn’t, there could be a variety of things happening. It could be that you have a defective blower motor, capacitor or fan center. Otherwise, the problem could lie with a dirty evaporator coil or filter. If none of these are the problem, check the fan connections – they could be burned or damaged.

If your air conditioner is not providing even heating throughout your home, check to see if your AC dampers or vents are open. If not, your AC might be too small.

My air conditioner cycles on and off constantly

If your air conditioner cycles on and off constantly, there could be a number of factors at play. First, you might be low on refrigerant, which would cause your AC to cycle more frequently. If not, your AC unit might just be too big – this would cause it to cool in short spurts rather than evenly.
