A homeowner in Mineola, TX called us with a frustrating problem — the house simply would not cool down in the afternoon, no matter how long the air conditioner ran. Our technician headed out to investigate and quickly found the culprit.
Up in the attic, there were large gaps and holes on the return side of the duct system. Instead of pulling in conditioned air, the system was drawing in scorching hot attic air. Attic temperatures in East Texas summers can easily climb to 130°F or higher in the afternoon. When your system is pulling in air that hot, no air conditioner can keep up.
We sealed all of the return air leaks thoroughly and then ran a full system test to confirm everything was working as it should. The unit is now performing the way it was designed to — cooling the home efficiently, even during the hottest part of the day.
If your home in Mineola, TX struggles to stay cool in the afternoon, duct leaks on the return side are a common cause that often goes overlooked. It is worth having a technician check your ductwork before assuming the air conditioner itself is the problem.
