We had a great experience with Mike and Cloud9 HVAC. They replaced our old oil heating system with a heat pump system using our existing ducts, and installed a mini split in a hot, attic-like upstairs room. Mike was friendly, knowledgeable, and never felt pushy. What stood out was his honesty. We were planning to pay to have a vent and duct moved, but after starting the work, he realized it would actually be more ef…

Brent, Mike and their team did an excellent job coordinating and making all the necessary paper work needed to install our HVAC.They were very accommodating and patient. They took time to explain everything to us. The team kept the work area clean. I gladly recommend Clould 9 Heat and air.

Brent and his team at Cloud 9 Heating were understanding of what my home needed, and provided a great recommendation at a reasonable price. His team was able to get my whole system replaced the following week and took just two work days for install. I received a few bids, Brent stood out as somebody who communicated the most effectively and made me feel secure in purchasing a new unit. I would highly recommend him!

They went above and beyond to ensure the concrete pad was shored up with an extra wood slat and minimal sheet rock cuts to run …
