Why is My A/C Blowing Hot Air?

Summer is not the time you want to have an issue with your air conditioner. If your Portland home isn’t cooling down but the A/C is running, or worse – it’s blowing hot air, there are a few troubleshooting tricks you can try. Let Heat Relief Heating & Cooling help identify and fix your A/C issues this summer!

Thermostat trouble

The first place to look when your unit is blowing hot air is the thermostat. It may sound silly, but just double-check to make sure that the system is set to “Cool.” You’ll also want the fan set to “Auto,” rather than “On.” If the fan is on continuously, it may blow warmer air when the air conditioner is not actively running.

Regular filter checks/replacement and cleaning

Your HVAC system must be clean to work properly, so there are a few places to check that you can clean yourself. First, check your filter—and replace it if needed. You should try to check your filter every month, especially when your HVAC is getting a lot of use, like during the hottest months of summer.

Next, you can check your outdoor unit. If there is a lot of dust or debris on it, be sure to turn off the unit and then give it a good scrub. If the unit is still blowing hot air, it may need professional cleaning. Our 19-point Precision AC Tune-up is a great way to get the machinery in your air conditioning system up and running smoothly again.

Power problems

Your outdoor unit may have a loss of power that could be causing hot air to blow inside your home. Check your circuit breaker and look for blown fuses. If your air conditioner has blown a fuse or is consistently tripping the breaker, contact an expert technician at Heat Relief as soon as possible to check on this electrical issue.

Reduced refrigerant

Refrigerant is an important element for your air conditioner, as it is necessary to cool the air that it is sending into your home. Low or leaking refrigerant is a relatively simple fix but needs to be serviced by a professional. Our Heat Relief techs can also check for any additional A/C issues, like if any ductwork in your home is leaking.
