How to Stop Your AC from Blowing Hot Air
An air conditioner is one of the most important pieces of hardware we can have in our home to help us survive the summer heat. So when you realize that your AC is blowing hot air instead of the cold air you were expecting, there’s a big problem.
There are a few reasons that this might be happening to you, and we’re going to go over the most common causes.
Check Your Breaker or Fuses
If your home has an integrated HVAC system built into a furnace, you may notice that the fan in your furnace is blowing air throughout your home, which it is supposed to do.
But that air isn’t cold, and when you check your condenser outside, you find the fan isn’t spinning.
Sometimes, the reason this can happen is that there may have been a power surge.
If your AC is connected to the circuit breaker system of your home, check your board to see whether or not the switch has tripped and reset it.
Just flip it back to the on position and your problem will be fixed.
But in some cases, an AC’s condenser unit will have its own separate fuses which have blown.
This means you’ll need to replace them before your AC starts working again.
Your Refrigerant Is Leaking
Refrigerant is the term used for different chemicals that have a very special property. When they are converted from a liquid into a gas, they absorb all the heat in the area, leaving only cold air.
Air conditioners operate by exploiting this property, constantly taking refrigerant built into the unit and converting it repeatedly from liquid to gas and back again.
Under normal circumstances, refrigerant in your AC should be almost “self-contained,” never needing to be replenished.
However, mechanical defects, punctures or damage to your condenser, and other issues can cause it to leak. Once that happens, you lose cooling efficiency, then you lose cool air entirely.
Your Condenser Is Freezing
It’s hard to keep anything icy during a hot summer in Texas, but under the wrong circumstances, your condenser can do it.
You may examine your condenser and see that it’s acting like it’s in the middle of raging blizzard, covered in ice and icicles, despite the heat of the season.
This means, unfortunately, that none of that cool air is getting pumped into your house, it’s getting wasted cooling down your condenser.
Mechanical defects, a blockage in air flow from your condenser into your home, or even refrigerant problems could all be causes for a condenser icing up in this way.
You are going to need to turn off your AC unit for a while in order for it to thaw.
