    Tom is a great service provider in the hvac field. Had high electric bills and my unit just seemed to be running too hard and my house not cooling down quickly and he realized… well I forgot what it was but the coils on the unit were clogged and on top of that checked my unit out completely to make sure it was running perfect. Bills have dropped dramatically since then. Highly recommend.

    Tom and Steve came out on a Sunday because our air conditioner had quit on a Saturday, which was a 100 degree day. Tom was fast, efficient and had our house cooling in no time. We were so happy with their great customer service and knowledge of AC units. Tom explained everything to us and then quickly replaced the part and charged us a very reasonable price for the job.. Thanks guys!!

    AC was leaking Freon, causing high bills. Tom came out and correctly diagnosed problem. He also researched my warranty and got me new parts for free, saving me over 1K in bills. Tom installed the new parts, and on a separate note also put in a new water heater that I needed. He is very responsive whenever I call. This is the only company we call from here on out! Very honest and quick to show up at house.
