AC and Heat Pump Troubleshooting
Troubleshooting Tips for Your Air Conditioner or Heat Pump IssuesWhen your AC starts blowing heat or stops altogether, your instinct might be to call your local HVAC repairman ASAP. Before you reach for the phone, see if you can troubleshoot your AC System or Heat Pump issues the problem first. This will save you costly callout fees and may be a quick fix. We have pulled together a list of things you can safely troubleshoot on your air conditioner before you call.
Things To Check If Your AC System Isn’t Cooling
- Check the thermostat batteries: Sometimes, when your AC stops blowing cool air, it isn’t a problem with the HVAC unit at all. Before you panic, replace the thermostat batteries and check your system again.
- Inspect the Filter: Over time dust builds up on an HVAC filter. This blocks the airflow, reduces efficiency, and can even cause your HVAC system to stop. Most Carrier and Bryant HVAC systems need their air filters changed every couple of months.
- Examine the Air Vents: Go room by room in your home and double-check that air vents (both return and supply) are open and aren’t blocked. Sometimes vents are shut during winter and we forget to reopen them. Also, long drapes can cover floor vents.
- Survey the Outdoor Unit: Dirt and leaves can build up around your AC unit outside which can cause inadequate cooling. Gently hose off any small amounts of dirt and sweep away the leaves. Also, make sure that there are no large objects within 2 to 3 feet of your unit.
Things To Check If Your Heat Pump System Stops Running
- Check the Thermostat Setting: If your system isn’t running, look to see if the thermostat is set to COOL, not HEAT. Also double-check that your thermostat isn’t in direct sunlight. This can cause your system to read the wrong temperature.
- Analyze the Circuit Breaker: Locate the electrical panel in your home and make sure all switches are in the ON position. If the circuit breaker to your AC is tripped, firmly push it into the ON position and check to see if your AC starts running. If the breaker immediately trips again, have a professional look at it.
- Try the Master Power Box: Your HVAC system has a main power switch outside. It is usually located a few feet from the HVAC unit and is mounted on the outside wall. Check that the power is ON.
