The AC Emergency Breakdown Checklist

Is your air conditioning suddenly not working correctly? Before you call for AC service, here are a few things you can check on your own that could get your cooling system back up and running!

1. Check Your Thermostat

Sometimes you think you’re dealing with an AC breakdown, but really it’s a problem with your thermostat and your air conditioner is fine. Did the batteries in the thermostat die? Did the settings get accidentally changed? Is your thermostat on the “Cool” setting?

2. Check Your Air Filters

Air filters help reduce air pollutants from circulating through your ductwork and into your breathing air, but they need to be changed regularly! If your air filter is very, very dirty, it can cause your AC to turn off or the evaporator coils to freeze. A good rule of thumb is to change your air filters at least every three months, but it is best to check the manufacturer specifications of your heating and cooling system.

3. Check Your Power Switch

Many HVAC systems have a power switch next to the furnace or indoor AC blower unit in your basement or attic. It looks like a regular light switch—is it possible that someone accidentally flipped it off?

4. Check Your Breakers

Head over to the electrical panel and check to see if there are any tripped breakers. If there are, flip them on and see if the AC turns back on. If it just tripped once, it’s probably okay, but if the breaker connected to your air conditioning system keeps tripping, you’ll want to call a professional for AC repair.

5. Check the Outside Unit for Obstructions

Are weeds, plants, leaves, or branches piled up around the outside AC unit? If your condenser can’t get proper airflow, it could be affecting or preventing operation. Make sure that the area around the outside unit is clean and cleared away.

6. Check Your Vents

If your AC sounds like it’s running, but it doesn’t feel any cooler inside and the temperature’s not going down, take a look around the house at the different vents. Is furniture partially or completely blocking them? Did your kid take their sweatshirt off and accidentally throw it down on top of a vent? Are the dampers closed for some reason?

7. Check Your AC Unit’s Age!

It can be easy to lose track of just how old your AC is! If your unit is more than 10 years old, it could be time for AC replacement!
