Getting through the warm spring and summer months means you need an air conditioner to blow cold air reliably. If your AC is blowing warm air, what can you do?
Plenty of things can go wrong with your HVAC system. Warm air could be a small issue, or it could indicate a larger problem that requires a professional fix.
If your air conditioner isn’t cooling as well as it should, check out these five tips to learn how to fix an AC that isn’t cold.
-
Check the Thermostat
The temperature setting could be the culprit if you wonder, “why isn’t my AC cold.” Even if you’re sure you set it cold enough to blow cool air, double-check that setting if you feel warm air through the vents.
After you confirm the thermostat setting reads “cool”, and the temperature is low enough, experiencing warm air can indicate other issues.
-
Replace the Air Filter
A clogged air filter restricts airflow through your AC unit. When your system has to work too hard to circulate air, it can struggle to cool the air blowing through your vents.
If you can’t remember the last time you replaced the filter, it’s time to do it now. Check the filter and replace it with the correct size for your system. If a new filter doesn’t resolve the warm air issue, you might need to consult a professional HVAC service for maintenance or repairs.
-
Check the Power
When your HVAC system loses power or trips a breaker, it can blow warm air after regaining power. Check the circuit breaker box to make sure the system has power. If you still notice warm air after the system restarts, a professional technician can investigate potential issues to get the air blowing cold again.
-
Clean the Outside Unit
Before taking the outside unit apart, call an air-conditioning expert. They can safely remove pieces to gain access to the inner workings of your AC unit.
An HVAC specialist knows how to clean dirt and debris from inside the unit and around the exterior. They’ll also check the outside drainage to ensure the area is free of clogs. A clean outdoor unit runs more efficiently to circulate cool air into your home.
-
Replace Refrigerant
You’ll need an HVAC technician for this task, too. While inspecting your system, a technician will check coolant levels and replace refrigerant, if needed.
They’ll also inspect hoses and connectors to find the source of a leak that depleting the unit’s refrigerant levels.
Don’t Suffer If Your AC Is Blowing Warm Air
There’s no need to suffer if your AC is blowing warm air! Start with the simple solutions by checking the thermostat and replacing the filter. If those things don’t result in cold air, it’s time to call an HVAC service professional.
