My Air Conditioner Won’t Turn Off

My Air Conditioner Won't Shut Off - Air Conditioner and HVAC repair in Vancouver WAIt’s hot out and you’ve realized your air conditioner never stops running. This is one of the most common air conditioner problems during the summer. Below are some general reasons your AC won’t turn off. If you are experiencing any of these, contact the professional HVAC technicians of Vanport Mechanical in Vancouver WA! We can provide residential HVAC service & repair no matter the issue.

Check Your Thermostat

Although it may sound simple, your thermostat is one of the first things that should be checked. Look at the fan settings on your thermostat. If the fan is set to “On” instead of “Auto” the fan will run continuously until you turn it off or back to auto.

You can also test your thermostat by placing a thermometer near it. If after an hour the temperatures aren’t close to one another, your thermostat likely needs replacing.

Fan Limit Switch

Check the “Fan Limit” switch. It’s located near or on the blower. If it’s on “manual,” the fan will continue running despite the settings on the thermostat. Changing this setting to “auto” will ensure the fan only runs when it’s directed by the thermostat settings. If you’re having trouble locating the switch, you can contact Vanport Mechanical and one of our certified technicians will help.

Airflow Restricted

Your air conditioning system requires a certain amount of airflow to cool your home. If the airflow is restricted or blocked, your system will work harder and longer. Check for dirty air filters and open the air vents in every room, making sure they aren’t blocked by furniture or drapes. Also, consider hiring an HVAC professional to look for any leaky or disconnected ducts in your home. At Vanport Mechanical, we can check your home for any improperly sealed ductwork.

Undersized AC Unit

If a heat load was not performed when your AC was installed, or you have added on or installed larger windows without having your HVAC system assessed, it could be that your AC is undersized. An undersized system will run non stop as it struggles to cool your home. Most homes in the Pacific NW are designed for a cooling load of 85°. If your system is only running continuously when we reach 100° temperatures, it’s likely working just fine.

Your HVAC system is a mechanical device and failures do happen. It’s possible a limit, or control has failed.

Maintenance Required

Many of these issues can be taken care of with regular maintenance. At Vanport Mechanical, we recommend your air conditioning system be serviced by a professional at least once a year to make sure everything is working properly and efficiently. If you rely on the Vanport team for annual or seasonal HVAC maintenance, you’ll enjoy several exclusive benefits. Regular maintenance customers receive a discount on parts, as well as priority scheduling in the event of a breakdown.
