Highly recommend!Posted on Google E.J MartinTrustindex verifies that the original source of the review is Google. We highly recommend Altitude Heating and Cooling for HVAC systems. Justuce and Dylan replaced our 26 year old, 2 HVAC systems in March, 2026 . It was a wonderful experience that we had with them. They were dedicated, attention to details and especially, they care for their customers. Here’s an example. We had a clothes dryer vent that directly blew out to heat pumps and had to clean up occasionally for years. They bought a vent and flex hose for the new location and its perfect location. They didn’t charge for the materials and labor, and it was a surprise gift for us. It was an example of how they care about their customers and take pride in their work. The HVAC systems are expensive. They gave us 3 options to work within our budget to find the right fit for us. I hope this review helps you decide to hire this company to install your house systems. We’re lucky to have Justuce and Dylan. Nice work Gentlemen!Posted on Google linda boysenTrustindex verifies that the original source of the review is Google. Great service!
