Michael came out next day after he got our part and fixed our blower fan motor fast and for a fair price. He was great to chat with and answered all my questions. I will definitely refer him and use him when we need him again. Family owned and local is who we like to support.

Michael from Flatirons Heating and Air is awesome. Incredibly prompt to reply, easy to work with, and super trustworthy. Unlike a lot of other servicing companies. I never felt like he was trying to upsell us on anything that we didn't need. I'd highly recommend using them.

Excellent service from Flatirons Heating and Air! They scheduled us quickly and got our A/C and furnace repaired fast during a stretch of 90-degree weather. They even brought portable cooling units to keep our home comfortable while we waited, which really went above and beyond. Their team was professional, honest, and trustworthy—they recommended only what we actually needed and never made us feel pressured into unnecessary repairs or extra costs. I highly recommend Flatirons Heating and Air and will be using them for any HVAC needs in the future.
