Key facts for hiring an HVAC contractor in Denver

How to get written quotes on one scope

Start with the building type, existing fuel, equipment location and whether the project is replacement alone or part of a renovation. Denver names Repair/Replace and Alteration/Tenant Finish in its application instructions. Ask each quote to spell out equipment, duct changes, electrical work, permit handling and inspection tasks so omissions are visible. Source; read 2026-10-30.

Do you need a permit for a heating or air-conditioning job in Denver?

Denver's permit document “2025 Denver Building & Fire Code” (read 17 October 2026): “For work performed on an emergency basis outside of normal business hours (8:00 AM – 5:00 PM, Monday - Friday, except City holidays), and to maintain an existing service or equipment when the maintenance is necessary to protect health, life or safety, the application for a permit shall be made within 3 normal working days after commencement of the emergency work.” Open Denver's source document

Furnace repair Denver

For a Denver furnace repair request, describe the fault, existing fuel and whether replacement is an option you want priced separately. The city heating-fuel estimates distinguish utility gas from electricity; they do not identify the system in your home. Ask the written diagnosis to separate the proposed repair from any replacement scope. Census heating-fuel data; read 2026-10-17.

Denver-Stapleton has 5,764.9 annual heating degree days in the 1991–2020 normals, base 65°F. That climate context is a reason to ask about heating performance, backup heat and sizing assumptions if replacement is proposed. A station normal is not a load calculation for your house. NOAA station data; read 2026-10-17.

Ask which heat source the quoted equipment will use.

NOAA explains: “The degree day is one measure of the weather related energy demand.” Ask for equipment sized to that climate.

Median hourly wage for Heating, Air Conditioning, and Refrigeration Mechanics and Installers in the Denver-Aurora-Centennial, CO area, May 2025: $34.41 (U.S. Bureau of Labor Statistics, Occupational Employment and Wage Statistics).

This is what workers in this occupation are paid per hour. It is not what a contractor charges for a job.

How does InstaBids work?

InstaBids does not hold payment for the work; you pay the contractor directly on the terms of the bid you accepted.

How is InstaBids different?

Each bidder appears under a stable label such as Contractor A, so you judge the work, not the brand.

Contact details stay hidden until the homeowner picks a contractor and they confirm the connection.

The contact-detail filter can miss disguised contact details.
