About Us

Your Local Castle Rock HVAC Experts

Castle Rock sits outside Xcel's territory. Black Hills Energy supplies the gas and CORE Electric Cooperative supplies the power, so the Xcel rebates you see advertised around Denver don't apply here. Two programs still do. Power Ahead Colorado pays $1,500 toward a cold-climate heat pump with no income limit, and the $1,000 Colorado heat pump credit comes off your invoice. We file both. The Town requires a permit for HVAC replacements. We pull it, schedule the inspection and size every system with a load calculation for your house. We install Bosch, Carrier and Mitsubishi.

What's Different in Castle Rock

6,202 ft elevation
  • No Xcel rebate: Castle Rock isn't Xcel territory for gas or power. You still get Power Ahead Colorado ($1,500 on a cold-climate heat pump) and the $1,000 Colorado credit.

  • Permits are required: The Town of Castle Rock requires a permit for furnace, AC and heat pump replacements, pulled by a registered contractor. We pull it and book the inspection.

  • Higher elevation: At about 6,200 feet, gas furnaces have to be set up for altitude. We size and set up every furnace for the home's actual elevation.

Afshin and Aydin were great to work with! The whole process from solution design through installation went smoothly, all at a fair price. They were always responsive and the job finished on time. Couldn't recommend more.
