For a long time I was just residing with inferior AC conditions; My air was hot, stuffy, & slightly stinky! What was going on with it? I then realized that I needed to prioritize my cooling istation, and living in Plano, Texas means that I deal with high heat & brutal humidity basically all year, going without an optimal AC component just isn’t possible, and i blamed my main indoor air handler for the stuffy air. I had a Plano AC tech come to my apartment to inspect the innertoilings; He checked over the fan blades, motor belt, condensate drain, & all moving parts. He cleaned the air filter, added more coolant, & said it was great to go. I tried the AC again & still there was sizzling air around my house… The AC serviceman then did some inspecting. Turns out the problem was not with the unit, but with the fastened ductwork. There was a crack along the seam of the duct. That crack was allowing the Texas, stuffy air to leak inside the house. The apartment felt warmer & the AC had to work harder, and no wonder my energy bills were so high. The AC serviceman was able to patch the seam with sealant particles that he shot up in there. It took him less than an hour. There was no odor, residue, or venice of the job. I did notice that my house felt so much colder after he did the ductwork sealing appointment. It shows you that you need to have your AC situation assessed on a yearly basis in Plano, TX.
