It’s coming! That first hot stretch of summer when open windows and ceiling fans just can’t cut it anymore. That’s when you need the power and performance of your air conditioner to provide much-needed relief. But nothing is more dreadful than turning on your system only to find it blowing warm air, making funny noises, or simply not starting at all. You can avoid this situation by being aware of potential AC issues. Here are six common AC problems and what to do about them:
1. Your air conditioner does not turn on.
Turning your unit on during a heat wave and getting no response can leave you panic-stricken. The cause could stem from a thermostat issue or a tripped circuit breaker. Check your thermostat batteries and replace if needed, and confirm the settings are in cooling mode with your preferred temperature. If your unit still does not turn on, try flipping the circuit breaker switch to reset it.
2. Your air conditioner is not blowing cold air.
This could be caused by a dirty air filter, an obstruction in the ducts, or the presence of debris blocking the air flow and causing the compressor to overheat. Air filters should be replaced every month or two to prevent obstructions—especially if you have pets.
3. Your AC refrigerant is leaking.
When the coolant in your air conditioner starts leaking, the temperature will vary, and the unit will not perform accurately. Refrigerant leaks can result in:
High power consumption
Regular maintenance checks from our highly trained technicians can detect issues. If there is a problem, we can repair the leak and recharge your air conditioning system so it’s working properly once again.
4. There are unusual noises coming from your air conditioner.
Your AC system should operate quietly. So when it starts making strange sounds, there could be a problem that needs to be addressed. There are different reasons why your air conditioner is producing a variety of sounds:
A refrigerant leak can produce a hissing sound.
If you hear clicking sounds when you turn your AC on and off, you might have a relay problem.
Thumping, rattling, or banging noises mean there is a problem with a blower or motor assembly.
The compressor or fan motor produces a screeching noise.
Faulty electrical components produce a buzzing sound.
If you hear unusual sounds, we recommend taking immediate action to avoid costly repair.
5. Your outside air conditioner unit is freezing up.
It can be surprising to see ice on your outdoor condenser and line set, especially in the middle of summer, but it frequently happens. Your air conditioner can freeze up due to:
Low outside temperature
Low coolant levels
Blower motor problems
It is important not to run your AC unit when it is frozen because it could cause additional damage to your unit.
6. There are water leaks.
Dust, algae, and other debris can block your AC’s drainage pipe, prohibiting the condensate from flowing out via the drainage system. When this happens, the water does not flow outwards, instead it overflows, causing your AC to leak water. Improper drainage can cause mold, fungus, and mildew to grow, and a foul odor to infiltrate into your home. You can avoid drainage issues by regularly maintaining, cleaning, and inspecting your unit.
