Possible Why Your AC Blows Hot Air

Filters need change

Hence, when your AC unit starts to blow hot air, perhaps it’s now time to get your air filters replaced or at least cleaned. This is particularly true when you’ve never tried replacing or even washing the filters before or after your unit is used heavily. Even if this task can be done by anyone, it would still be best if you leave this to the experts’ hands.  

Dirty or clogged air ducts 

Determining whether your air ducts are either dirty or clogged might not be simple since they are located within your walls. However, when your air conditioning unit starts blowing hot air and there’s no problem with the unit itself, perhaps it is because of the air ducts. It’s crucial to clean your air ducts because having dirty ones can only result in several health issues, particularly when there is pooling water.  

If you want to get your air ducts washed, you can always contact an HVAC repair or maintenance provider who can professionally do it for you. Plus, they’ll have the right tools for efficiently cleaning your air ducts, which often leads to great results. It’s highly recommended to get them cleaned at least once every 3-5 yrs.  

Incorrect thermostat settings 

It might be shocking at first, but when a thermostat is incorrectly set, it can be a culprit of why your AC unit blows hot air. Hence, before you check anything else, make sure that your thermostat is not set on the heat setting but rather on the cool setting.  

Sometimes it can be due to the thermostat’s fault as well. If this is the case, an HVAC maintenance expert can help quickly fix the issue. When this isn’t the reason behind it. Then keep on reading the listed issues below.  

Leaking refrigerant  

When your air conditioner unit blows hot air, then it could be due to refrigerant issues because it’s in charge of eliminating heat from the air in your home. It’s simple to know whether the refrigerant of your air conditioner is leaking, while ice will start to develop all over your AC unit. Though there are several reasons why a refrigerant starts to leak, it’s mostly because of no maintenance and heavy use.  

It would be great to get a certified HVAC contractor who can replace your refrigerant since touching the liquid yourself can be damaging to your skin. Also, HVAC technicians are expected to have the right tools required for safely changing the refrigerant. Also, make sure to get your AC serviced at least 2 times per year to keep it from blowing hot air again.
