Client Testimonials

Our furnace stopped working on a cold day and Ryan came out within 1 hour of calling. He was extremely professional and helpful, able to diagnose what was going on and temporarily fix our system at a very fair cost as well as consult on future updates we should make. We would definitely work with them again and recommend them for anyone with HVAC needs

Rachel S.

I was that person who had their furnace go out on Christmas eve. I messaged Thin Air on Christmas day hoping to get a response the day after. Donald messaged me back within an hour and had a tech out first thing the next day! It was time for a new furnace and they were able to get the job done that same week. Super happy with the service and professionalism of this team!

These professionals do the best work and I had five different people I’ve worked with in the past, and they are by far the best. They always find the most creative and most cost-effective solution while still having the units perform at their best I’m blown away by how good these guys are!

Caleb K.

My furnace blower went out on a 40+ year old unit. Thin Air responded rapidly and professionally on a Sunday. They tried repairing the motor first and then we determined that a new unit was most effective. They completely replaced and installed a new Rheem HVAC unit the next day. I am pleased with their communication and quality of work. I’d use them again and recommend them.
