Dennis' Heating & Air Conditioning, Inc.

I have used Dennis’ for over 30 years at my house and at dozens of locations in my work in Shasta, Trinity and Siskiyou counties. I would not use any other company. They are truthful, friendly, very professional. They do outstanding work at a reasonable price.

Had a routine AC service by Dean from Dennis's Heating and Air. Dean was courteous, professional, knowledgeable and informative. He's a great representative of/for the company.

We were notified as to approximate time of arrival and work was performed professionally and expeditiously. We've used Dennis' Heating and A/C for years and continue to recommend their services.

I have used several other HVAC companies in Redding but when a friend recommended Dennis’ HVAC 6+ years ago I have used them exclusively. Excellent staff and they always do a professional job. I have them check my HVAC system at least twice a year and every service call has been great!

Our furnace went out and Clay found time to come out in between jobs and quickly Identified

and fixed the problem. He was knowledgeable, helpful and friendly. Our system never worked as it should and now it is efficient and heats our home quickly!! Thank you Clay and Dennis Heating and Air

Clay came out for a tune up and dis a great job getting my system ready for summer. He was on time, professional and informative. I will definitely be using Dennis Heating and Air again.

Clay is the very best!!! He spent his valuable time totally explaining and reassuring me that all was ok! I recommend clay and this business and I won’t use anyone else from here on out!!! Thank you Clay!!!! You are the best!!!

This my 2nd experience with Dennis HVAC for a/c repairs, both times very positive experiences;their work was thorough & professional.
Both times the work was explained to me and I feel very confident that the issue were resolved.
I highly recommend Dennis HVAC. Tks, Clay, for all of hard work today!

We had a problem with our aux on our hvac coming on more than normal. I called them and they were out in 1 hour same day. They rewired our thermostat correctly and tuned up the system. We had also used them a year before when we were told to replace our system by another provider. They were able to repair the system with very little cost and uts been running perfectly for 2 years since. (This time it was our thermostat). Highly recommend.

The people in the office were awesome with scheduling and information and the Tech was on time, professional, and knowledgeable. He made sure I saw and understood the issue and what repairs were made. Very reasonable cost as well.
