HVAC Services Built for Centennial Homes

Most of Centennial’s housing stock was built before modern high-efficiency HVAC systems were standard, and the systems that were installed have now been running for 25 to 40 years. Bi-level and tri-level floor plans with finished basements create zoning and airflow challenges that single-zone systems were not designed to handle well. And the combination of Arapahoe County’s dry climate, temperature swings between seasons, and aging ductwork means HVAC problems in Centennial homes are rarely simple.

WireNut covers the full range of residential HVAC services in Centennial, from routine AC and furnace tune-ups to full system replacements, duct cleaning, heat pump installation, and indoor air quality improvements. Whether your system is struggling to keep up or has stopped working entirely, WireNut has licensed technicians available the same day with honest diagnostics and upfront pricing on every repair and replacement.

Good reliable service and knowledgeable technicians. I was apprehensive at first as I thought they would charge a lot more for certain things, but I’ve used them twice already and I think their prices are fair and reasonable.
Thank you Wire Nut

So far so good! Really looking forward to working with them for new AC unit and furnace and tankless hot water heater..I'll add more to my review when the job is done..ps they caught that my house under from 16 years ago isn't up to code, so they are fixing that too. Tankless hot water heater went in today and it's great..they were VERY qualified and knowledgeable about all aspects of the job. The entire crew were pleasant and courteous. I really appreciate the work so far! I'm looking forward to having the AC, furnace combo up n running on Wednesday of next week. And I will review it then. I would have them in my house any time.

He vacuumed up afterward, always used shoe covers which we appreciate, and even moved furniture back to its place. He's a huge credit to himself and WireNut, well done Sir and thank you!

I am on the process of closing the sale of my home and experienced the A/C tripping a breaker. The house inside temp climbed to 85 degrees quickly. I called Wirenut and they scheduled an electrician for the next morning. The technician called me in the morning and because he knew we are closing on the house he decided to take an HVAC technician with him. Together they were able to identify a capacitor went bad in the compressor. Over the years I have always been impressed with the technicians with Wirenut. They are always professional knowledgeable, and courteous. I highly recommend Wirenut!
