I noticed that my air conditioner wasn’t functioning properly after heavy rainfall the previous weekend. I checked the thermostat, which seemed to be working just fine. I also checked the sensor in the thermostat, and it was adjusted perfectly. I then checked the air filters in the air conditioning unit. Unfortunately, that was not the cause of my air conditioning issues either. I recently had replaced the air filter a couple of weeks ago and went through several other steps to check on the status of my air conditioner. I could not find the problem until I called a professional HVAC specialist to come take a look at it. She told us that because of the heavy rainfall last week, the humidity in the air was off the charts. Apparently excess humidity can cause your air conditioners condensate drain to clog and not drain properly. When the air conditioner can’t drain properly, it can’t function correctly. The clog had to be removed by the air conditioning specialist. Another issue that could have caused drainage complications could be the mounting level. If a window air conditioner is not mounted on a level surface, such as if it were to be on a decline, it could disrupt the drainage of the unit. Luckily I just had to deal with humidity issue. Once the HVAC specialist removed the clog, our air conditioner was back up and running again. I mainly have to keep an eye on the humidity levels, and keep our HVAC specialist’s number handy in case our units drainage gets clogged again.
