Why Is My AC Blowing Warm Air?

With the return of the summer season, we depend on our air conditioner to get us through the intense temperatures on the rise. Your air conditioner can make or break your comfort during the season. Since we rely on our cooling system, it can be a headache when your AC starts blowing warm air. Fortunately, it’s a common HVAC issue that you may be able to troubleshoot.

If you’re unsure why your system is blowing warm air, Baldwin Heating & Cooling is here to help. If troubleshooting an issue becomes more than a DIY fix, we are here to address all of your HVAC needs and concerns. Read on to see how you can fix this error at home.

Troubleshooting Tips For Your AC Unit

A warm cooling system is an oxymoron that nobody wants to experience. When your air conditioner isn’t blowing cool air, there are a few steps you can take to combat the problem.

Inspect Your Thermostat

The thermostat should be checked first, even though it may seem obvious. It’s possible that the thermostat was mistakenly set to heat if your air conditioner is blowing hot air. If so, reset the thermostat to cool and check if the air conditioner starts to generate cool air again.

Check that the temperature is not set too high and the batteries are working. The “auto” setting only uses the fan while the air is heated or cooled. Your system will automatically shut off when the desired temperature has been reached. We recommend keeping your settings on “auto” to reduce your cooling costs.

Locate Your Breaker

Check the electrical panel to see if the HVAC system is powered. Your unit needs a lot of power to operate. As a safety measure, the circuit breaker may automatically turn off electricity when there is an excessive demand for power. To inspect your breaker, follow these steps:

• Find your electrical panel and check for a blown fuse or a tripped breaker.
• Switch the breaker off (in the opposite direction from how all the other breakers are turned on), then flip it on to restore power to the unit.
• Have a professional repair any blown fuses.

You should contact a qualified HVAC expert or electrician if your breaker keeps tripping in order to prevent possible air conditioner repairs in the future.

Check Your Coils

A dirty air filter can result in a dirty evaporator coil. It’s possible that the evaporator coil won’t have enough open airflow to allow for active cooling functioning when it’s blocked with dirt and debris. A dirty air filter may cause a frozen evaporator coil, creating a deeper issue.

Depending on the home, environment and filter type, a homeowner should change the air filter every two to three months. We advise setting a regular reminder to replace your air filter at the beginning of each month.

Have A Professional Repair Refrigerant Leaks

Low refrigerant is one of the key reasons why an air conditioner isn’t blowing cool air. You can have undercharged or overcharged refrigerant if your service valve is worn out, your joints are loose or your assembly is subpar.

Refrigerant, also known as coolant, can be extremely dangerous. Never attempt to repair refrigerant issues by yourself. To avoid refrigerant leaks, make an appointment for a yearly air conditioning tune-up. Act fast if you detect warm air blowing from your air conditioner, hissing or gurgling sounds or ice on your refrigerant line.
