Reasons Your Home’s Air Conditioner Isn’t Turning On
Over time, your air conditioner can develop common problems, such as a malfunctioning fan, uneven cooling of rooms and failure to blow cold air. The last thing you want on a sweltering summer afternoon is to find out your cooling system isn’t working, making you endure uncomfortable conditions without refuge. So, what’s making the unit not to turn on, and what can you do about it? Here are a few troubleshooting options:
Why Your A/C Unit Won’t Turn On
- Clogged Filter: A dirty filter causes your air conditioning unit to freeze up. As a result, the unit may stop turning on.
- Tripped Circuit Breaker: This will prevent electrical current from powering your system.
- Wrongly Set Thermostat: Your air conditioner won’t come on if your thermostat is set to “heat” mode.
- Batteries: Your A/C may not be turning on because of the low batteries in your thermostat.
- Refrigerant: Your A/C unit relies on refrigerant to cool your home. If there’s a leak, the unit won’t function properly.
- Broken Motor: Your unit won’t turn on once your motor suffers damage.
There’s no need to panic when your air conditioning system stops turning on. There are some simple fixes you can do before calling an HVAC specialist.
- Check your thermostat and ensure it’s set to “cool.”
- Gently remove your thermostat batteries and replace them with new ones.
- Inspect your air filter. If it’s dirty, replace it.
- Check your electrical wiring for a blown fuse or a tripped circuit breaker. Reset your home’s power.
If these solutions don’t fix your cooling system, a bigger problem such as a refrigerant leak or bad motor may be to blame. You’ll need to contact a professional.
