Customer Testimonials


Ductless Mini-Split Repair in Frederick, ST 80530

“My builder installed two mini split systems on my house and I have had ongoing issues with one of them, which the builder chose to not make right. Carbon Valley HVAC came highly recommended from a neighbor and I can see why. My entire interaction with them has been topnotch – professional and caring. Dale came and fixed my split system and I couldn't be happier. They have all of my future HVAC business as well as I will share the news with everybody I know.” – Michelle J.

Very Prompt, Courteous, Knowledgeable, and Efficient in Longmont, CO

This was my first time as a customer of Carbon Valley Heating & Air. My furnace wasn’t working. I called Carbon Valley Heating & Air, and they came out on a Sunday and fixed my furnace. The technician had the part on the truck and he put it in and the furnace has been running ever since. The charge for the Sunday service was minimal and worth it. The technician was polite and friendly. He didn’t waste time. He came in, got the job done, and was gone. I liked that they were so efficient. I was very satisfied.
