Who We Are
We started Delta T Heating and Cooling for one reason;
to provide fair and reliable system service and replacement to our clients at a reasonable cost.

By hiring Delta T you will rest assured that you were treated fairly and not overcharged for the work performed. In addition, we are licensed professional engineers so when we say we understand how HVAC systems work, we mean it. We also perform all the work. What you see is what you get.
Our name means everything to us and we will do everything possible to make sure you are satisfied with the services we provide.

We were very pleased with Adam and the crew. We found them knowledgeable, professional and competitive in price and we’re happy to recommend them.
Good experience with Delta T Heating & Cooling. Service Tech Garrett was on time, professional, and personable.
After getting several estimates and talking with 3 other companies, it was clear Delta T was the right company to replace our aging furnace and AC unit. They offered a very competitive price but what really impressed me was Adam’s knowledge, attention to detail and desire to make sure the installation was perfect. I highly recommend these guys, you won’t be disappointed.
They were great! Garrett the technician was very nice and thorough. I was able to make an appointment quickly, and their prices were reasonable!
I was so impressed With Delta T Heating & Cooling. They were a phenomenal company to work with and I will continue to use them! Thank you so much to Adam for taking care of our AC!

Delta T is my “go-to” HVAC service company. Always very prompt and extremely reasonable on price. You will be glad you called Delta T.
Every interaction with Delta T has been very positive and helpful! Mike went goes and beyond to help explain things & the maintenance plan has been very beneficial for us! Highly recommend!
Delta T has provided service for my HVAC system and water heaters at multiple properties for the last 4 years. Quick service, good communication, fair prices. I trust them implicitly.
The tech came and checked our heating system, got it all ready for winter, and explained everything I needed to know, for a reasonable price. Bonus, he also explained 2 or 3 ways why upgrades wouldn’t be necessary, and how to prolong the life of the system. Will definitely continue to use them.
They fit me in their schedule pretty late at night. Theres a storm coming and they were understanding and fixed my issue quickly. I purchased their program to have them come out annually now. Thank you guys!
Mike Jeanneret was our repairman and he thoroughly explained everything he was doing and why he was doing it. He didn’t charge us for anything we didn’t need and I feel confident that he was honest with his work. Would recommend to anyone!
I’ve used Delta for several years both at both my personal residence and my work building. They have always responded quickly and efficiently. I’ve been so happy with their service and never trust anyone else
