My AC Isn’t Blowing Cold Air: What Do I Do?

Monday, June 24th, 2024

Is your AC unit not keeping you comfortable? While there are many reasons why air conditioning systems can fail to do their job, it’s not always complicated. In some cases, the fix may be quite simple, depending on the source of the problem. If your air conditioner no longer provides you with the cool air you need, follow these five steps.

Check the Circuit Breaker

When your air conditioner is not blowing cold air, the first thing you should do is check the power source. It’s obvious, but a bad circuit breaker can prevent the air conditioning system from receiving the power needed to operate effectively. 

Similarly, issues like a tripped circuit breaker or faulty electrical outlet can disrupt power to the unit. Before scheduling repairs for more complex mechanical failures, make sure that your air conditioning unit is powered correctly.

Look at the Thermostat

Another key area to inspect when your air conditioner fails is the thermostat settings. Incorrect thermostat settings can lead to the air conditioner blowing warm air or not starting the cooling process at all.

As such, ensure that the thermostat is set to “cool” rather than “heat” and that the temperature setting is lower than the current indoor air temperature. This simple check makes sure that the system commands the air conditioner to blow cold air as expected.

Clean the Filters

Regularly cleaning the air filters is vital to the performance of your air conditioning system. Dirty air filters restrict airflow and significantly reduce the efficiency of the system by preventing the circulation of conditioned air.

When the air filter is clogged, the evaporator coil can freeze and block the flow of cool air into your home. As such, cleaning or replacing dirty filters will restore optimal airflow and improve the overall air quality in your space, which allows the air conditioning to function at its best.

Brush Off the Outdoor Unit

If your air conditioner still struggles with blowing cool air, try looking at the outdoor unit. Leaves, dirt, and debris can accumulate around the condenser coil and impede the heat exchange process necessary for cooling the air.

Regularly brushing off debris from the outdoor unit makes sure that your air conditioning system maintains its efficiency and effectiveness. This not only enhances the cooling performance but also extends the lifespan of the unit by preventing overheating.

Reach Out to an HVAC Technician

Should these measures fail, your best bet is to call an HVAC professional. An experienced technician can diagnose and address more complex problems such as a refrigerant leak, issues with the condenser unit, or mechanical failures in the HVAC system. Professional intervention guarantees that your air conditioning system receives the repairs it needs to continue functioning properly.
