Duct Sealing
The average Colorado home loses 20-30% of conditioned air through leaky ducts. That's money disappearing into your attic. Our aeroseal and mastic duct sealing stops the leaks and delivers comfort to every room — evenly.
  • Blower door and duct blaster testing
  • Aeroseal pressurized sealing technology
  • Typical energy savings of 20-30%
  • Before/after performance report included

About Granite Peak

Built for
Colorado
homes.

Boulder's climate is unlike anywhere else — a mile high, four distinct seasons, and temperature swings that can swing 40 degrees in a single day. We built Granite Peak HVAC specifically to serve homes and businesses on the Front Range, with technicians who live here, know the altitude's effects on equipment performance, and give you straight answers without the upsell pressure.

We believe your HVAC system should be a set-it-and-forget-it part of your home — not a source of anxiety every time temperatures shift. That's why every estimate includes a full explanation of what we're doing and why.

"

"We had a furnace failure the night before Thanksgiving — dropping into the teens outside. Granite Peak had a technician at our door within two hours. He diagnosed a cracked heat exchanger, had the part on his van, and our heat was back on before midnight. These guys are the real deal for Boulder families."

"We replaced our 20-year-old AC with a new heat pump system. Ryan's team walked us through every option without pressure. Installation was clean and finished in one day. Our electric bill dropped $80/month."

Mark T.

★★★★★

"Finally found an HVAC company that gives you straight answers. They told me my furnace had two more good years and exactly what to watch for — no scare tactics to replace it early. I'll be calling them when it's time."

Jennifer L.

★★★★★

"Had them install a mini-split in our converted garage studio. Perfect solution for a space with no ductwork. Quiet, efficient, and the install was done in half a day. Would 100% recommend to any Boulder homeowner with an older home."
