What Causes an AC to Blow Hot Air?

You rely on your air conditioning to fill your home with cool air on the hottest days of summer. So feeling hot air or lukewarm air blowing out of your vents can be an immediate cause for concern and a clear indication that there is a problem somewhere in your air conditioning system.

Identifying the problem and making the fix usually requires an HVAC professional who will be able to have your AC back to full functionality and producing cool air quickly.

There are a range of issues that could occur when a furnace malfunctions. Cold air, not enough air, weird noises, and strange sounds are all common occurrences that homeowners experience in Nashville with their gas furnaces.

Many of these issues require professional furnace repair for a safe and reliable service, but understanding what the initial cause was may help you prevent similar issues in the future and get a better understanding of how your appliances work.

Diagnosing the Cause of an AC Blowing Warm Air

When you first notice hot air coming out of your vents, the best first check is usually the thermostat to be sure the settings are correct. If a thermostat is set to cool with the correct temperature, you will next want to diagnose any issues:

If refrigerant has evaporated or leaked, there may not be enough in the coils to sufficiently cool the air as it passes through your AC unit. Depending on the cause of low refrigerant, the refrigerant may only need to be topped up, but if there is a recurring issue, more in depth repairs will be necessary.

Your air filter may have become clogged and is restricting air flow. This problem generally only requires replacing the air filter.

If your air ducts are disconnected from your AC or have a significant leak anywhere, the cool air your AC is creating could be escaping before it can reach your living spaces.

Likewise, if there is debris blocking your air ducts, cool air cannot make it from your AC to your living space.

While it’s important not to compromise on quality, make sure that the pricing is reasonable and transparent with no hidden charges.

The condenser controls the transfer of cold air. If there is a large amount of dirt on it, the reduction in surface area causes the entire system to take in less cool air.
