Top 7 HVAC companies in Larimer, Colorado

Larimer County sits in northern Colorado with a population of 356,899. Heating loads dominate because of 5,900 heating degree days against only 800 cooling degree days. Winter design temperature reaches 3 °F while summer design reaches 92 °F under very dry conditions. Two cost sources appear in public data and differ by several thousand dollars. Local licensing and permitting are handled entirely by city and county departments with no state HVAC license board. State heat-pump incentives in 2026 require contractors to hold CEO registration and pass through a minimum discount.

Cost of HVAC work in Larimer County

A typical full-system install is shown at $10,350 with a published range of $9,300 to $11,400. A separate 2025 invoiced average stands at $17,151, and the upper quartile reaches $25,373. Labor is listed at $120 per hour. Permit fees range from $150 to $500. The two cost sources disagree on the central figure; one reflects advertised or modeled pricing while the other reflects actual billed amounts. Altitude derating and dual-fuel configurations common in zone 5B can move final pricing within either range. Homeowners comparing bids should request line-item breakdowns that separate equipment, labor, and permit costs.

The shortlist

This shortlist is built from public listing data, not a review of work performed. Companies are ranked by a Bayesian-adjusted rating that pulls each star rating toward the national mean of 4.764 until the firm has enough reviews to stand on its own. Small tie-breakers apply for a public website, HVAC-specialist listing category, and published 24/7 availability.

A Team HVAC

A Team HVAC operates from 514 Huntington Hills Dr, Fort Collins, CO 80525 and lists the phone number (970) 792-7154. Its raw rating of 5.0 sits above the national mean and is pulled down to an adjusted score of 4.944 after 44 reviews. The score before tie-breakers was 4.904; the public-website signal supplied the final lift. The general-contractor listing suggests the firm handles a broad range of residential work rather than HVAC-only projects. These numbers cannot reveal how the company schedules multi-day installations or handles warranty claims.

Master HVAC Fort Collins

Master HVAC Fort Collins operates from 2726 S College Ave, Fort Collins, CO 80525 and lists the phone number (970) 398-8782. Its raw rating of 5.0 is adjusted to 4.886 after 16 reviews. The score before tie-breakers was 4.846, with the public website providing the tie-breaker margin. The Services category points to focused HVAC work. The modest review count keeps the adjustment noticeable; the numbers say nothing about parts availability during peak winter calls.

Reliable Fort Collins HVAC Repair

The score before tie-breakers was 4.809; both the public website and published 24/7 availability contributed to the final placement. The general-contractor listing combined with 24/7 availability suggests readiness for emergency service. With so few reviews the adjustment remains sizable; the numbers cannot indicate average wait times once a call is placed.

Its raw rating of 4.8 sits above the national mean and is adjusted to 4.846 after 49 reviews. The score before tie-breakers was 4.786; the public website and 24/7 availability supplied the tie-breakers. The general-contractor listing indicates mixed plumbing and heating work. The larger review count narrows the gap between raw and adjusted scores; the numbers do not address how the firm coordinates permits across multiple Larimer County jurisdictions.

HVAC Services: Heating & Air Conditioning

HVAC Services: Heating & Air Conditioning operates from 203 W Mulberry St, Fort Collins, CO 80521 and lists the phone number (970) 512-9794.

Its raw rating of 4.0 sits below the national mean and is adjusted upward to 4.306 after 63 reviews. The score before tie-breakers was 4.246; the public website and 24/7 availability supplied the tie-breakers. The general-contractor listing combined with round-the-clock availability points to broad emergency coverage. The larger review count limits how far the score moves; the numbers cannot indicate how the firm performs on high-altitude equipment derating.

Licensing and permits in Larimer County

Colorado has no state HVAC contractor licensing board. Licensing and permitting are handled entirely by individual city and county building departments. The example given is Denver’s Community Planning and Development department, which issues Mechanical Contractor licenses and mechanical permits. No statewide HVAC insurance minimum exists because there is no statewide HVAC license. Colorado DORA licenses only electricians and plumbers at the state level. Homeowners must contact the specific city or county where work will occur to confirm current requirements. Permit rules vary by jurisdiction, and fees in the data set range from $150 to $500. Verification of any local license or registration should occur directly with the issuing department before signing a contract.

Climate demands on HVAC systems

Larimer County falls primarily in IECC zone 5B with a dry moisture regime. Heating degree days total 5,900 while cooling degree days total only 800, producing a heating-leaning mixed load profile. Winter design temperature is 3 °F and summer design temperature is 92 °F. Very dry conditions year-round make humidification common in winter. Natural gas remains the primary heating fuel, and heat-pump suitability is described as good with backup, either dual-fuel or cold-climate units. Altitude derating is required on equipment sizing because of large diurnal swings. Evaporative cooling remains viable in this climate. These conditions place the greatest demand on heating equipment reliability and proper sizing rather than on peak cooling capacity.

Available incentives in 2026

The Colorado Home Energy Rebates program through CEO remains limited. Maximum heat-pump rebates reach $8,000. A state heat-pump tax credit is available in 2026: $1,000 for air-source, $2,000 for ground- or water-source, and $250 for heat-pump water heaters. The credit must be claimed by a CEO-registered contractor who passes through at least 33 percent as a customer discount. Utility rebates from Xcel Energy, Black Hills Energy and others range from $700 to $2,500. The 25C and 25D federal tax credits expired at the end of 2025. Because the state credit is available only through registered contractors, homeowners must confirm registration status before proceeding with any heat-pump project.

How to choose an HVAC contractor

Confirm the contractor holds any required local license through the city or county building department. Verify CEO registration if pursuing state heat-pump incentives, because unregistered firms cannot deliver the tax credit. Request written confirmation of altitude derating on any gas furnace or heat-pump quote. Compare line-item pricing that separates equipment, labor at the listed $120 hourly rate, and permit fees. Ask for current references from recent Larimer County installations rather than relying solely on star ratings. Check that the listed phone number and address remain active before scheduling a site visit.
