Four Reasons Your AC Is Blowing Out Hot Air

Tower Heating and Air on March 15, 2023

North Carolina has just entered its “third winter,” aka one of the state’s 12 actual seasons—following fool’s spring, second winter, and spring of deception (Google it, it’s a thing). Nevertheless, warm weather is coming! Which naturally means that you’ll be switching on your AC soon. Just like your furnace can blow out cold air when you turn it on for the winter, your AC unit may blow out hot air when you switch it on at the first sign of warm weather. Here are a few reasons why that might happen, and how we can help fix the problem.

Low Refrigerant Levels

If your refrigerant levels are low, your air conditioning system may have a leak, which usually causes it to blow out warm air. If you encounter this problem, call us! We can fix the leak, restore your refrigerant levels, and have your AC unit blowing out cold air in no time.

Dirty Evaporator Coils

A crucial component of your AC unit, evaporator coils help your system function correctly and efficiently, so it’s important to keep them clean. Throughout the year, the coils can collect dust, dirt, and debris, which can inhibit your system from working properly. Make sure to schedule regular tune-ups so we can ensure everything is clean and good to go.

Lost Power

If your AC unit doesn’t have power, it could mean that your circuit breaker tripped or you blew a fuse. We can check both of these systems to make sure they’re providing power to your indoor unit.

Incorrect Thermostat Setting

The problem could be as simple as your thermostat setting. We’ve all been there! Double-check to make sure your thermostat is set to “cool,” and the fan settings are set to “auto,” not “on.” If your fan is set to “on,” it could be the reason your unit is blowing warm air throughout your home.

Ensure a Cool Spring/Summer

Cool air in NC is crucial, especially as we head into those super hot summer months! Make sure when you switch on your AC for the season everything is running smoothly, and if it’s not, give us a call at 919-646-2940 to see how we can help.
