Mike Cohen
I was told by another company that my compressor was dead. Thankfully Eric did some due diligence and had my system online in 20 minutes or so. An honest competent technician is refreshing. I wish I called McCullough first.

My AC stopped working on Saturday. Called McCullough, and they had a tech to our home first thing Sunday morning..The tech, Sean, was professional and prompt. He checked our outside and inside unit, and had the issue diagnosed within minutes. He explained the cost and set our mind at ease. He worked swiftly and fixed the capacitor, what seemed like minutes. I highly recommend McCullough and have nothing but high praise for their tech Sean.
