When your air conditioner fails during extreme heat, it is more than just uncomfortable. It can quickly become an emergency. Knowing the most common air conditioner problems homeowners face can help you act fast, minimize damage, and restore comfort to your home as quickly as possible. North Country Aire will share the top emergency air conditioner problems and what you should do if they happen.

Complete System Failure

One of the most urgent issues is when your air conditioner won’t turn on at all. When your air conditioner will not turn on, it could be caused by an electrical issue or blown fuse, a faulty thermostat or a failed capacitor or compressor. Check your thermostat and circuit breaker first. If everything appears normal, call an HVAC professional immediately.

Air Conditioner Blowing Warm Air

If your system is running but not cooling, it can feel just as bad as no air conditioner at all. When you have warm air blowing through the vents this might be due to low refrigerant, dirty coils or a malfunctioning compressor problem. Warm air during extreme heat can quickly raise indoor temperatures to unsafe levels.

Refrigerant Leaks

Refrigerant is essential for cooling. A leak can prevent your system from working properly and may damage the compressor. If you have a refrigerant leak, you may hear a hissing or bubbling noise. There may also be ice building up on refrigerant lines or even a reduced cooling performance from your air conditioner. Turn off your system and contact a professional. Refrigerant issues require specialized handling.

Frozen Evaporator Coils

Ice buildup on your indoor unit can stop your system from cooling entirely. Some common causes of frozen coils include restricted airflow, dirty filters or low refrigerant due to a leak. Turn off your air conditioner to allow the ice to melt and avoid further damage. Then schedule a service call.

Electrical Failures

Electrical problems can prevent your system from starting or cause it to shut down unexpectedly. Common start up failure may be due to a tripped breaker, bad wiring or a burnt out capacitor. When there is an electrical issue, contact an HVAC service as they should always be handled by a licensed technician.

Short Cycling

If your air conditioner is turning on and off frequently, it’s not completing proper cooling cycles. You may have a problem with your thermostat, have dirty air filters or a refrigerant issue. Short cycling increases energy use and puts excessive strain on your system.
