Frequently Asked Questions

What is the average cost of a new HVAC system in Colorado?

Are there state-specific rebates available for Colorado residents?

Yes, Colorado offers a $1,500 state tax credit for Energy Star heat pumps. Additionally, Xcel Energy customers can often access rebates between $6,000 and $9,000 for qualifying cold-climate heat pump installations.

Do I need a permit for HVAC installation in Colorado?

Yes. Most Colorado jurisdictions (Denver, Aurora, Colorado Springs, etc.) require a mechanical permit. Installations must comply with the 2021 International Energy Conservation Code (IECC) as mandated by state law HB22-1362.

While gas furnaces are traditional, modern 'dual-fuel' systems (heat pump + gas backup) are becoming the Colorado standard. They maximize efficiency during cool days while providing reliable gas heat during extreme mountain freezes.
