Having issues with your air conditioning unit? If so, you’ll want to check out our guide for air conditioner troubleshooting. Depending on what’s wrong with your AC, you may be able to resolve the issue yourself without calling our HVAC contractors.
We understand that many of our customers have a budget and appreciate being able to save money when they can. This guide for air conditioner troubleshooting is just one of the many ways we look out for you.
When was the last time you changed your air conditioner filter? If you can’t remember, the filter is probably clogged with dirt, dust, pet hair, and other contaminants. When this happens, the air conditioner isn’t able to push air through the filter like it normally would, forcing it to work harder and use more energy. A dirty filter can also make the evaporator coil ice up until the leaking overflows the condensate drain pan.
While our HVAC contractors can change the filter during routine air conditioning service, it’s your responsibility as the homeowner to make sure it’s changed as needed. If you have pets or smokers living in the house, you may need to change the AC filter more regularly. You’ll know it’s time to change the filter when it’s gray in color and covered with dirt and dust.
As the weather warms, you’ll want to change the thermostat setting from “Heat” to “Cool.” When the thermostat is set to “Heat,” this means that it’s programmed to turn on the furnace once the temperature drops below what you set it to. Otherwise, thewon’t turn on even when the temperature rises above what’s considered comfortable.
Do you feel warm air coming from your vents? If so, check your thermostat for the fan setting. If the thermostat is set to “On,” this means that the fan will run continuously, regardless of whether or not your air conditioner is sending cool air. To fix the issue, simply set the fan to “Auto” so it’ll automatically kick on with the air conditioner to move cool air throughout your home.
If the evaporator coil is frozen, turning the fan setting to “On” is a temporary solution that’ll help prevent further damage to the compressor. We recommend schedulingas soon as possible and keeping the AC turned off. Otherwise, the evaporator coil will continue to freeze.
Is the AC tripping the circuit breaker? The circuit breaker is designed to prevent too much power from overwhelming your home’s electrical system and starting a fire. When the circuit breaker detects too much electricity for what’s considered safe, it shuts off the power to your home as a safety measure. Circuit breakers can also trip when they need to be replaced or their connecting wires are loose.
While you can easily reset the breaker, you’ll want to call an electrician if it’s a recurring problem. We can also make sure that the circuit breaker isn’t tripping because of a clogged filter or more serious issue.
The indoor AC unit will have a switch in a nearby closet, basement, or attic. Since this switch looks like a normal light switch, many homeowners accidently turn them off. However, doing this will turn off the blower and shut down your air conditioning unit. Once you turn on the switch, wait a few minutes for the air conditioner to start cooling your home. If nothing happens, you may need to call our HVAC contractors for air conditioning repair.
