How Do You Fix Your AC Blowing Warm Air?

Summer is here in full force. While pool parties and barbecues are fun ways to spend the summer, we all rely on the coziness of our homes to provide a welcome break from the heat. This is when we most rely on our air conditioners. This is also HVAC technicians’ busiest season. Every day during the summer, we receive calls about air conditioners that are blowing warm air. Fortunately, it’s a common HVAC issue that may be fixed by the homeowner in some cases. We would like to help you fix these problems on your own. But if it does not work out or you are short on time, look for air conditioning in Fort Worth.

How to Troubleshoot a Warm-Air-Blowing Air Conditioner


  • Thermostat

It is the first thing to check if something like this happens.
Fix: Check that the thermostat is set to “cool” and that the temperature is appropriate. Replace the batteries if they’re worn out. We recommend setting the thermostat at around 78 degrees Fahrenheit during the cooling season, and 7-10 degrees higher while away from home. You can save 10% on your annual heating and cooling bills if the setback time is 8 hours long.

  • Circuit Breaker

If thermostat settings are alright then the next thing to check is the circuit breaker.
Fix: Look for a tripped breaker or a blown fuse in your electrical panel. Flip the breaker completely off (opposite way of all other breakers) and then back to the “on” position to re-energize the unit. If a fuse has blown, you’ll have to replace it. You should also label your circuits.

  • Evaporator coils and AC Filter

A clogged air cleaner can obstruct airflow and cause your home to overheat. It can even force the system to pack up completely in extreme circumstances. So, get your ac filters cleaned. An evaporator coil is a component of the indoor component of your central air-con system. Because reaching the evaporator coil is hard, it’s preferable to go away repairing difficulties with a frozen evaporator coil to an HVAC professional. So, look for AC repair in Fort Worth.

  • Condenser Coils

It’s time to evaluate the outside unit now that you’ve checked the thermostat, breaker box, air filter, and indoor coils. Fix: Turn off your outside unit at the source if it’s clogged. Then, using gloved hands, remove the larger things while rinsing the smaller trash with your garden hose. Consider calling a pro if you think work is a bit hectic.

  • Refrigerant Leak

If you notice ice formation or something like that, then it might be a refrigerant leak. A refrigerant leak can cause your AC system to prevent blowing cold air, run prolonged periods of your time without sufficiently cooling your home, or cause a damaged or failing compressor and complete system shutdown, counting on its severity. Fix: Immediately call a pro and get the leak to be repaired. So, look for AC repair in Fort Worth.
