Is Hot Air Coming From Your AC? Here’s Why
Summer can pretty much guarantee that things are going to be hot and humid for the next few months.
It’s a welcome environment for people that are looking to enjoy some outdoor activities, but if you need to work efficiently or get a good night’s sleep, it can be a big problem.
This is where modern technology like centralized air conditioning becomes so useful. It’s supposed to maintain a comfortable temperature, but when it doesn’t, you need to address it quickly.
If you’re getting hot air from your HVAC system, there are a few common causes.
No Electricity to the Condenser
A typical HVAC system has a furnace in the home for heating integrated with a condenser outside that cools the air, and then sends it to the furnace.
Even if the furnace isn’t heating a home, the fan inside it is used to pump air throughout.
So if you’re getting hot air, this means your furnace fan is working fine, but your condenser outside isn’t.
In some cases, some may be surprised to see that their condenser covered in ice and icicles despite the hot summer day.
This isn’t as rare an occurrence as you might imagine.
If this happens, don’t take it to mean you have a “super air conditioner” compared to other homeowners. It’s the opposite.
The reason your condenser is covered in ice but blowing hot air into the home is because none of the air that it is cooling down is being sent to your home.
It’s all being used up right the condenser itself.
This may mean you’re getting a block to the air flow, it could mean there’s a mechanical defect in your ventilation system, or it could be a problem with your refrigerant.
Your Refrigerant Is Leaking
Without refrigerant, modern air conditioning couldn’t exist. This class of chemicals is what makes cooling technology so efficient.
When changing from liquid to gas, refrigerant draws in all the heat during this reaction, leaving only cool air behind.
Air conditioners simply take this phenomenon and repeat it endlessly, converting refrigerant from liquid to gas and back over and over again.
Normally, you don’t have to worry about running out of refrigerant. It’s not a fuel that’s burned up in the same way gasoline is in an engine. It simply changes states; it’s not consumed.
But if you get a break in your refrigerant storage or some other problem occurs that causes a leak, once your refrigerant is gone, so is your AC’s ability cool things down.
