Why Is My AC Blowing Hot Air? A Homeowner’s Guide
Even the most repair-savvy homeowners can experience the stress and frustration of an AC unit that is only blowing hot air.
In most cases, this issue is aggravated by the heat and humidity that you are trying to escape.
Luckily, this is a fairly common problem that only has a certain amount of causes.
Before you get stressed out over an air conditioner blowing hot air, consider these common issues that could be the problem:
Tripped AC Breakers
Constantly tripping the AC breaker is frustrating and inconvenient. For many homeowners, it’s a sign that the air conditioner is using too much electricity and it is overloading the breaker panel.
Some of the reasons for this include:
- An inefficient AC unit that is working harder than usual due to dirty air filters, broken fans, overheating, or low refrigerant.
- An incorrectly installed AC unit that is not compatible with the breaker panel.
Regardless of the issue at hand, a professional should look at any electrical work involving your air conditioner, that way you won’t experience any accidentals or problems in the future.
Frozen AC Unit
Sometimes, the AC unit can get too cold and freeze on the inside, resulting in a snowball effect of problems throughout the unit.
The most common component to freeze is the evaporator coil.
This component handles cooling and condensing the returning air from the system.
If the coil becomes damaged, it will freeze and stop working.
A broken evaporator coil results in increased humidity in your home, a noise condenser unit, and hot air blowing out of the registers.
Depending on the severity of the problem, we may recommend cleaning the coil, repairing it, or completely replacing it.
Leaking or low refrigerant in the AC will cause hot air to blow from the registers since the unit is not exposed to the correct amount of cooling fluid.
When it comes to dealing with a refrigerant leak, you may feel tempted to simply add more fluid to the unit and call it a day.
However, without finding the underlying cause, you would simply experience the same issue repeatedly.
Some of the most common issues that cause refrigerant leaks include manufacturer’s defects, accidents that puncture the tubes, or incorrect installation.
These reasons are why it’s so important to work with a qualified AC specialist.
They will get you the correct warranty information, make sure the repair is carried out correctly, and add more fluid as it is needed once the problem is solved.
