See how we've made a difference for our clients.

I called them because my heat when out and they were able to come same day to fix the problem! They had fantastic service, were friendly and very reasonably priced! They did excellent work and we will use them for any future heating needs we have!

These great gentlemen are very knowledgeable, polite, and excellent at what they do. They came out on a Wednesday for initial inspection of the issue I had needed addressed. They figured out the real problem which was not far off from what I told them when I scheduled (that morning). They figured it out in left than an hour. They were able to schedule me and got the repair done in a very precise time frame and came back the following Wednesday. They didn't let the flooding stop them from coming. They repiped my air vent and made it better than before to prevent the problem from happening again. They are the ONLY. People I will trust with my home! Thank you again Justuce and Dylan.

Team was great. From the recommendations, knowledge, timeliness and transparency, everything was easy and quick. Would definitely recommend and will be using the team for any future work we have.

Great experience with Altitude Heating and Cooling replacing my electric furnace with a heat pump. Great communication, quick installation and amazing quality of work. They went above and beyond replacing damaged ducting and related components to ensure the system met expectations. Incredibly happy with the installation. Overall a really positive experience. Would highly recommend this team.

Always responsive, personable, and professional. I’ve had multiple projects completed, from running gas lines to installing the tankless water heater and they care about quality and take pride in their work. I called when my water heater was leaking and they installed the tankless that same day, lifesaver! They’ve built trust which is a hard thing to find.
