Matthew S. was very thorough, patient, professional and knowledgeable. And a pleasant person to have in our home. My HVAC unit was recently installed by McCullough, so there was no charge.

I just had a free plumbing inspection at our house as part of being a Comfort Club member with McCullough. James Farr was the plumber who did the inspection and his visit was very informative and pleasant, as well. He was very thorough and assessed our plumbing in ways I wouldn't have thought of, checking the usual areas but also water quality and hardness. I recommend this service to anyone, especially if you live in an older home, like we do.

When my AC went out, McCullough was recommended to me.
I am glad they were.
From the man who came out to check it, Raul, the man who came to explain my options, Evan, to the two that came out and to install it, Miguel and co-worker (sadly I didn't catch his name), it was a quick and smooth experience.
I will be recommending McCullough to any and everyone with HVAC issues.

Jaiden was very helpful and thorough. Instead of just identifying the obvious issue he took the time to try to look into the cause, and was willing to work around my schedule for the follow up repairs.
