One of the rare few that can be trusted to do the job right for a fair price
We've gone through multiple HVAC companies over the years and Adam/Brittany have been one of the best
Work/Knowledge is superior
Willingness to ACTUALLY tackle a problem is better than most
Within a few hours, he was able to resolve problems at several of our properties that other contractors weren't able to for years

We had a whole new heating system put in our house. He did a great job with everything. And he's available to answer questions when we have them. Highly recommend!

Highly recommend Coltella/Adam. Have used him for 2 jobs at my previous house and he did an amazing job. I got several quotes and he did the job for a lot less money.

Adam/Coltella Heating & Cooling replaced our outside air conditioning unit and inside coil after our 21 year old system failed - We were very happy with the process from start to finish - The quote was VERY competitive and the install timeline very favorable - Brittany (Adam's wife) was great at responding to all of my emails/questions in a very pleasant and prompt manner - The actual install was seamless - Highly recommend.

Adam and Brittany are awesome! Adam re-did our entire house with a new HVAC several years ago and we continue to be so happy with his work! He comes annually to clean the furnace, and comes quickly when we have anything funky happen with our rather old furnace. When we needed a propane heater installed in the barn to keep us warm this winter, he was our first call. We love Coltella - excellent work, fair pricing, great response and scheduling!

Adam really knows his stuff. He’s accommodating, even in emergencies, and always thorough for every job. He always looks out for his clients’ best interests. I’d recommend him to anyone with HVAC needs.

Highly recommend Coltella Heating and Cooling. Great company to work with, the communication throughout the project was excellent. The systems they recommended for my home have been fantastic. Over a year after the system was installed a random flickering of the power in my home caused an unusual error code, turned my heat off in the middle of the coldest part of the year, this all happening on aSaturday night. I called the owner, Adam, and he was at my house in under an hour and had my system back up and running.

My dad’s furnace broke down in the middle of the 20 degree cold snap and Brittany was able schedule us an emergency appointment in spite of Adam’s already busy schedule. Adam quickly diagnosed the problem and got the heat back on in short order. We are so grateful and impressed with Adam’s expertise and down to earth attitude and cannot say enough great things about our experience. If you’re looking for a smart, honest, compassionate company to service your home heating or cooling needs, Coltella Heating and Cooling is THE one to call! Thank you Adam and Brittany for your truly outstanding service!!
