Heat pump troubleshooting skills are handy to have when you’ve got a heat pump on the blink. It can be a hassle to get someone to fix it, and until they come, you’re left out in the cold. So before you call an HVAC technician, it’s wise to be sure the problem isn’t a minor one that you can fix yourself. Here are some tips for troubleshooting heat pumps before you call for repairs.
- Unit doesn’t run. Check the power. Be sure the power is turned on, also checking to see if the circuit breaker has been tripped. Turn that back on as well. If you have power, check the thermostat. Be sure it’s on the proper setting, and try turning it up a few degrees to see if anything happens. If not, you may have the wrong model, or it may be wired incorrectly.
- Unit won’t heat or cool properly. One problem that homeowners who are heat pump troubleshooting sometimes ignore is making sure nothing is blocking airflow from the registers. A register is the vent in the ceiling in the wall that serves as the supply air or return air for your heat pump unit. Then check the air filter to see if it’s clogged. Replace it if necessary. If that doesn’t work, call a technician to check the blower, coils and other components.
- No air is coming out of the vents. Check the fan switch on the thermostat. If it’s on, turn it off. Many heat pumps are designed to shut off automatically if they get too hot. In that case, your problem may be the unit’s limit switch. If the motor is running, but no air is coming out, then there may be a broken belt. Call an HVAC technician to fix it.
- Strange noises. Some mechanical noise for heat pumps is natural, if annoying of too loud then you should have it checked. An HVAC contractor can offset ordinary heat pump noises with some flexible, insulated ductwork. If you’re hearing a rattling sound, try tightening the cover panels, then check to see if there’s a loose component. If you hear a squealing or grinding noise from the motor, shut the unit off and call an HVAC technician.
