AC Not Blowing Cold Air

Updated: Feb 10, 2023

What’s worse than an air conditioner that doesn’t work at all? An air conditioner that isn’t blowing cold air…in Florida.

Unfortunately, this is a problem that plagues homeowners at the most inconvenient times. But don’t worry, there’s no need to panic just yet. We’re here to help.

Read on to learn six commons reasons your air conditioning system isn’t blowing cold air and how to troubleshoot them.

Girl Enjoying Air Conditioning

1. Wrong Thermostat Settings

If your air conditioner isn’t blowing cold air, the answer could be as simple as your thermostat being on the wrong setting.

Setting your fan to “AUTO” will not only save you money, but it will also ensure that your fan is only running when your air conditioner is cooling the air.

When your fan is set to “ON,” your air conditioner is running 24/7, regardless of whether it’s cooling the air or not.

2. Dirty Air Filter

Before you do anything else, check the air filter first. Excess debris can impede airflow, which can make your home feel warmer.

If the air filter is dirty, swap it for a fresh one and get in the habit of changing it each month.

A longer lasting filter is another one of the pros of keeping your fan setting on auto. While many people like to change their AC filters once a month, there are those who wait for their air filter to look the same as their lint trap after a few weeks.

A dirty air filter prevents air from flowing back into the air conditioner which inhibits the AC from cooling correctly.

3. Refrigerant Leak

Refrigerant is necessary to cool your home, but if there isn’t enough refrigerant in your air conditioning system due to a refrigerant leak, your home is going to feel warmer than usual.

Refrigerant is dangerous to handle so schedule an inspection with your local HVAC technician.

4. Air Duct Leak

Air travels through a series of air ducts before reaching the rooms in your home. Over time, air ducts can become poorly sealed, lose insulation, and cause air to leak.

This can cause excess cool air to escape instead of going into the rooms of your home like you want it to. When cool air escapes, it’s difficult for your home to reach the temperature you want.

If the air ducts in your home are older, schedule an inspection with your local HVAC technician.

5. Dirty Evaporator Coils

Over time, the evaporator coils get dirty, which can affect the overall performance of your air conditioning system and make it harder to remove warm air.

This can ultimately lead to the air conditioner overheating and shutting off. Evaporator coils should be cleaned by an experienced technician, so we recommend scheduling an appointment.

6. Check Your Circuit Breaker

Breakers trip all the time but when your AC isn’t blowing cold air, your mind probably presumes the worst.

Your air conditioning connects to two circuit breakers; one for the outside unit and another for the inside.

If the outside breaker trips and the inside breaker is still functioning, the air can’t be cooled.

Reset the breaker, but if it happens again don’t be too fast to reset it as it could cause damage to your AC.
