How this list was built
Every company here was checked by loading its own website on August 29, 2026. Only facts published on that company's own site are recorded — how they describe their service area, whether they list furnace installation, and what they say about ownership.
Three things this list deliberately does not do.
No rankings or ratings. Alphabetical order, nothing else. We haven't hired these companies and can't credibly score their work.
No phone numbers. Look each company up directly. That way you're reaching them through their own site rather than a number republished by someone with an interest in your call.
No independence claims we couldn't verify. Several sizable Denver-area HVAC names are owned by private-equity groups or out-of-state parent companies. That's not a knock — plenty of them do good work — but "locally owned" means something to homeowners, so companies we couldn't confirm as independent were left off rather than described loosely.

How to choose a heating contractor
A furnace is a $6,300 to $8,650 purchase in this market, and the contractor matters more than the brand on the box. A well-installed mid-range furnace outperforms a premium unit installed carelessly.
Get three estimates. They will disagree. The disagreement is informative once you can see why — usually equipment tier, whether venting work is included, and whether all three sized the furnace the same way.
Insist on an itemized quote. Equipment, labor, materials, and permit as separate lines. A single number at the bottom of a page tells you nothing you can compare.
Ask how they sized it. The answer should reference a load calculation and Denver's altitude. Gas furnaces lose roughly 4% of capacity per 1,000 feet, and the metro sits above 5,200 — a contractor working from sea-level tables will undersize your house.
Confirm the permit is included and they're pulling it. A mechanical permit runs $80 to $150 here and triggers the inspection. That inspection is the only independent verification that the gas and venting work was done correctly.
Ask about the ductwork. Especially in older Denver housing, where the median home dates to 1975. Returns sized for a 1970s furnace may not carry what a modern high-efficiency unit needs.
Questions worth asking before you hire
Five that separate a real contractor from a salesperson:
- What's your local mechanical contractor license number? Colorado has no statewide HVAC license — the state licenses electricians, plumbers, and radon professionals — so ask about city or county credentials specifically rather than accepting "licensed" as a general claim.
- Can I see your certificate of insurance?
- What capacity did you calculate, and how did you account for elevation?
- What's the labor warranty, and separately, the manufacturer's parts warranty?
- Is this current-production equipment or pre-2026 inventory? Colorado's low-NOx standard took effect January 1, 2026, but furnaces already in Colorado warehouses before that date are exempt and can still be sold. Either is legal — you just want to know which you're buying.

Questions
Frequently Asked Questions
Why does a referral site publish a list of other contractors?
Because it's useful and we'd rather be straight with you. We connect homeowners with one insured local heating professional — that's how we make money. But you may want to compare, and a list of real local companies is genuinely helpful. Everything here comes from each company's own website, with no rankings and no ratings.
Are these companies ranked or rated?
No. The list is alphabetical and carries no scores, stars, or 'best of' claims. We haven't hired these companies and we're not in a position to rate their work. Inclusion is not an endorsement and the order means nothing.
Why are some well-known Denver HVAC companies missing?
This list only includes companies that appear to be independently owned based on statements on their own websites. Several large Denver-area names are owned by private-equity groups or multi-market parent companies, and a few had ownership we couldn't verify either way. Those were left off rather than described inaccurately.
How do I know these listings are accurate?
Every entry was checked by loading the company's own website on August 29, 2026, and only facts published there are recorded. Websites change, companies get acquired, and service areas shift — verify anything that matters to your decision directly with the company before you hire.
Should I get more than one estimate?
Yes, three is the usual advice for a job this size. Expect the quotes to disagree, because equipment tier, whether venting work is included, and how each contractor sized the furnace all move the number. Line them up and the differences usually explain themselves.
