I never knew how crummy my old system was until Randy and the Comfort Zone team replaced it with an Amanda heating and AC unit. They did a fantastic job that looked as neat as could be. They got it done quickly with no hassle and cleaned up after themselves. I highly recommend Comfort Zone! I could not be happier!

Randy is very courteous and knowledgeable. He and his staff designed a great system for our rental duplex, worked around our tenants schedule, completed the work in the timeframe promised, and cleaned up when they left. I have used their services for many years, will continue to do so and recommend them to you without any reservations.

Excellent service, good work, no surprises. Randy, Chris and Davy were all great to deal with. Invoiced exactly what I was quoted. Good communication before and during the work. Upsized gas line from the meter and ran new line to kitchen and garage. Highly recommended.

I would NOT recommend this company. They were over double their estimate and the mileage was outrageous. It took a week for them to come back and finish a day job. Even the material cost wasn't accurate and it was only a couple of fittings to hook up the in-floor heat. I also had to UPS Next day air a new manifold in because they overtightened and cracked it. Luckily a local guy came and finished the installation correctly and fixed Comfort Zones shoddy work.

Randy and his team do a great job. Chris walked me through a house I recently purchased, familiarized me with my water, garage heat, and Hvac systems, and told what I needed to know, which was very helpful. I will reccomend this company to friends and family.

Randy M. responded very quickly to our call and was answered all our questions. We learned that our A/C unit was ok, but just needed some TLC. Randy provide great recommendations and when the time comes for our heating and air to be replaced/updated he will most definitely have our business. I would highly recommend him to anyone without hesitation.
