Crawford Family
Another company told me I had to replace my entire unit because they couldn’t figure out why my drain pan was holding water constantly…obviously it’s the main line…the other company cleared the lines (but didn’t) and said that the only solution was replacement of entire system quoting changes in refrigerant.
McCullough came in and saw that the drain line was blocked from inside unit because of faulty installation leaving materials in unit. So the cleaned the line correctly and opened the plenum to see the issue. They redid the lines and added floats that were faulty and ‘snaked’ the lines rather than some CO2 cartridge cleaning….completely comprehensive. They fixed it and saved me money…A LOT OF MONEY - didn’t need a replacement just someone who can diagnosis a problem. They charge a fair price and instantly earned a customer for life.
If you are looking for honesty….and a fair price - this is your people. Oh, and they took pictures and videos and explained everything as well as share it with me…professional, knowledgeable, and fair pricing. Highly recommend with absolutely no doubt….

Thomas saved the (100 degree) day! A minor issue with major consequences (drip pan drain pipe). He was quick and professional.
