Why is Your AC Blowing Warm Air? Ask the Experts


You turn the air condition on, and it feels like this is the first time you’ve experienced hot air coming out of an ac unit. You start to wonder if there’s something wrong with your system. But what could be causing your cooling system to act up differently?

When an air conditioner blows hot air, there is almost always a straightforward explanation that can be fixed by a 24 hour ac repair specialist. Here are common reasons why your ac unit may be blowing hot air.

Your AC is Dirty

Your ac doesn’t need to look dirty to start having issues. To see on the outside is just as important as what you do. The evaporator and condenser coils collect dust and other things over time. Eventually, they can get so dirty that airflow is compromised, and the compressor could start to shut off.

Cleaning your ac regularly not only helps it operate at maximum efficiency but also helps prevent potential repairs or replacements down the road.

You have a Dirty Air Filter

A dirty air filter reduces airflow and can cause your unit to have issues keeping up with cooling. When you have a dirty filter, the evaporator coil will get hotter than it should because it cannot do its job correctly. You also run the risk of moisture building up in the system when airflow is restricted and can end up with a moldy air conditioner unit.

Your AC has been Tampered with

A common problem with air conditioners is that people try to fix or adjust their own units without knowing what they’re doing. If someone has tinkered with your system, you may run into problems blowing hot air. A qualified technician should only work on your ac unit.

Your Air Conditioning Unit is Old or Showing Signs of Wear

With an older air conditioner, it won’t be able to keep up with the ever-increasing demands of today’s homes. If your ac units are ten years old or more, be sure to get them inspected and serviced every year. If you see that your ac is struggling or making weird noises, there’s a good chance that you’re going to need an air conditioning repair service soon.

You’ve had Shut Offs in Your Home

If your air conditioner has been shut off for long periods without the home being vacant, then there’s a good chance that you’re going to need to replace your air conditioner unit.

When an ac sits idle for an extended period, it can cause problems in the long run, and your warranty does not cover this type of wear and tear. A 24-hour ac repair expert can help you decide if your ac unit is too old and needs to be replaced.

Your Home has a Low Coolant Level

When the refrigerant levels in your ac get low, or a leak forms in a pipe or a coil, it can cause it to blow hot air. Many homes have their air conditioning units filled once a year, and this is an excellent time to examine your unit for wear and tear. If you have an older ac system, experts recommend being inspected before the summer begins every year.

If you have noticed at any time that your ac unit is blowing hot air, it may be time to get help from a 24-hour ac repair service.
