Broomfield is the only place in Colorado besides Denver that is a consolidated city and county, a structure it adopted in 2001 after spending decades split across four separate counties. That constitutional quirk has an ordinary consequence for anyone replacing a furnace: the HVAC companies in Broomfield pull the mechanical permit from Broomfield's own building division, and a Broomfield inspector, not a county one, signs the work off. The paperwork never leaves the jurisdiction, and the contractor either knows that counter or does not.
The second thing worth understanding before you call anyone is what Colorado does and does not certify. The state licenses plumbers and electricians through the Department of Regulatory Agencies, and those records are public. It does not issue a state HVAC or mechanical contractor licence at all. Mechanical work is governed locally, which in Broomfield means a city contractor licence and the 2024 International Mechanical Code, adopted along with the rest of the 2024 code family and the Colorado Low Energy and Carbon Code under Ordinance 2295. At the technician level the credentials that mean something are NATE certification and EPA Section 608, the federal certification required of anyone who opens a refrigerant circuit.
So we set the entry requirement at a Broomfield operating address rather than a Broomfield service-area page. Firms headquartered in Westminster, Louisville and Lafayette that list the city among two dozen others were set aside, however good their work may be. Every surviving candidate was then run against Colorado's open licensee file for any plumbing or electrical credential it holds and for disciplinary history. Five companies cleared both tests. None paid for a place, and none knew they were being evaluated.
How We Evaluated Broomfield HVAC Companies
The Top 5 HVAC Companies in Broomfield
2026 Rankings · City and County of Broomfield
Kappler Mechanical
Kappler carries the densest verifiable credential stack of any HVAC company operating from a Broomfield address. Its own site states NATE certification and EPA certification for its technicians and Mitsubishi Premier Diamond Contractor standing, the tier that determines how ductless and heat pump warranty claims are handled. The Better Business Bureau records the firm as accredited with an A rating since 9 August 2004, which is twenty-two years of continuous accreditation rather than a badge collected last quarter.
The Colorado open licensee file confirms Kappler Mechanical & Electrical, Inc. of Broomfield holds an active electrical contractor registration, number 102206, with no disciplinary action recorded. That matters more than it sounds: a mechanical company that can also pull electrical work in-house is not subcontracting the circuit when a heat pump or a whole-house electrification project needs one. The company publishes an aggregate of 4.99 out of 5 across 507 customer reviews on its own reviews page.
Its service map is the tightest fit for this page. Kappler works Broomfield, Boulder, Louisville, Lafayette, Superior, Erie, Arvada, Westminster, Thornton and Brighton, which is a genuine north-metro radius rather than a Denver operation reaching north on a good day.
Cooper Heating & Cooling
Cooper is the largest company on this list and the oldest, headquartered on Colmans Way in Broomfield since 1978. Its own history page names founder Gary Cooper and states that his son Luke took over as owner and president in 2023 after four years in the US Army. The company reports an A rating with the Better Business Bureau held annually since 1990, Bosch Home Comfort Pro Platinum contractor status, repeat Dave Lennox Award recognition, and a place among Xcel Energy's top high-efficiency rebate providers since 2010 — which is the credential most likely to save you paperwork, because rebate processing is where homeowners usually get stranded.
Colorado's open licensee file returns two active registrations for Cooper Heating & Cooling, Inc. of Broomfield: plumbing contractor 1639 and electrical contractor 8267, both current and neither carrying a disciplinary entry. Yelp lists 344 reviews against the Broomfield address.
The trade-off is scale. Cooper's published service area runs from Castle Rock to Longmont, so a Broomfield homeowner is one call among thousands rather than a neighbour. For a straightforward replacement backed by the deepest paperwork and rebate machinery in the city, that is a fair exchange; for a fussy diagnostic job, the firms below may give you more of the owner's attention.
Kraemer Mechanical
Kraemer publishes its Broomfield address, 7249 W 116th Ave, Unit 16, directly on its own contact page rather than leaving it to directories, and the Better Business Bureau records the firm as accredited with an A rating since 28 June 2021. The BBB profile lists Kyle Kraemer as owner and operator and dates the LLC to February 2020; the company's own site describes more than twenty-five years of trade experience behind it. We are reporting both figures because they measure different things, and a reader comparing bids should know which one is the entity's age.
The distinguishing capability here is commercial refrigeration alongside residential heating and cooling. Very few Broomfield-based firms of this size carry it, and it is the reason Kraemer turns up on small commercial jobs — restaurant and retail equipment — as well as house calls. The company states it services York, Rheem, Lennox, Bosch and Trane equipment and keeps emergency availability outside its posted weekday hours.
Kraemer holds no state contractor registration in the Colorado licensee file, which is unremarkable for a mechanical firm because Colorado does not issue one. If you are hiring it for anything that touches plumbing or electrical, ask which licensed trade partner is doing that portion and get the licence number before work starts.
Tico HVAC
Tico is the smallest operation on this list and the one whose Broomfield address is confirmed by the most useful third party: Bryant's own dealer locator lists the company at 4855 W 127th Pl, Broomfield, CO 80020. A manufacturer's dealer directory is a considerably harder thing to get a fictitious address into than a review aggregator, which is why it carries weight here. The Better Business Bureau separately records the firm as accredited with an A rating since 28 September 2022 at the same address, and lists Jeison Ricardo Miranda Salas as owner.
The published scope is narrower than the larger firms above but points in a useful direction for Broomfield's newer housing stock: heat pumps, boilers, and energy recovery ventilators alongside conventional furnace and air conditioning work. ERV capability in particular is worth knowing about, because tightly built homes in the newer north Broomfield subdivisions frequently need mechanical ventilation that older stock does not.
The company's site states more than seventeen years of industry experience and describes itself as a small family business; the BBB dates the LLC itself to February 2021. As with any owner-operator, confirm EPA Section 608 certification for whoever is actually on your roof or in your mechanical room before refrigerant lines are opened.
Kerwin Plumbing & Heating
Kerwin is on this list for one specific reason and is ranked fifth for another, and both are worth stating plainly. The reason it is here is that it is the most thoroughly licence-verified heating business in Broomfield. Colorado's open licensee file returns Kerwin Plumbing & Heating Inc of Broomfield holding an active plumbing contractor registration, number 818, current to February 2027 with no disciplinary entry, and William Kenneth Kerwin holding master plumber licence 179668, active and first issued in August 1990. The file also still carries the expired 1971 journeyman and 1975 master licences of William D. Kerwin, the founder, which is an unusually literal paper record of a family trade passing between generations.
The reason it is fifth is scope. Kerwin's published services centre on boilers, water heaters, backflow prevention and plumbing, and the Better Business Bureau dates the business to 13 April 1978 with accreditation and an A rating since 18 September 2007. If your Broomfield home runs on hydronic heat — and a good deal of the older stock in Broomfield Heights and the Original Broomfield neighbourhoods does — this is the strongest credential set in the city. If you need cooling, look higher up the list.
The company also states EPA lead certification for its plumbers, which is the credential that applies when work disturbs painted surfaces in a pre-1978 home. Given the age of the housing stock this firm has served since the year that rule's cutoff was set, that is not an incidental detail.
Frequently Asked Questions: HVAC in Broomfield
Do I need a permit to replace a furnace in Broomfield?
Yes. Because Broomfield is a consolidated city and county, its own building division issues the mechanical permit and its own inspectors close it out — the work is never referred to a surrounding county. The city advises allowing one to two business days' turnaround on emailed permits for air conditioner and furnace replacements where no modifications are needed, and states that the inspection must be scheduled by the property owner or the contractor before a permit can be finalised. Inspectors run assigned routes and generally arrive between 8:30 a.m. and 4 p.m. Ask any contractor you hire, in writing, who is pulling the permit and whose name it is issued in.
Does Colorado license HVAC contractors?
Not at state level. The Colorado Department of Regulatory Agencies licenses plumbers and electricians and publishes those records, but the state issues no HVAC or mechanical contractor licence. Mechanical licensing is handled by local jurisdictions, and in Broomfield that means a contractor licence issued by the city and county itself, with proof of general liability insurance; applicants in the plumbing and electrical trades must additionally supply their current state and master licences. When a company tells you it is "state licensed" for HVAC, ask which licence and look it up. Every state registration cited on this page was checked against Colorado's public licensee data, including for disciplinary action.
Which building code does Broomfield enforce for HVAC work?
Broomfield adopted the 2024 edition of the International Building, Mechanical, Plumbing, Fuel Gas, Existing Building and Fire codes, together with the 2023 National Electrical Code, under Ordinance 2295, effective 15 April 2026. The adoption also brings in the Colorado Low Energy and Carbon Code. The practical upshot for a homeowner is that equipment installed in Broomfield from that date forward is inspected against the 2024 International Mechanical Code and the state energy code, so a contractor working off an older edition may specify combustion air, venting or condensate details that will not pass. Confirm your contractor is quoting to the current adopted code.
What certifications should a Broomfield HVAC technician hold?
Two matter above the rest. EPA Section 608 certification is a federal requirement under the Clean Air Act for anyone who maintains, services, repairs or disposes of equipment containing regulated refrigerants — it is not optional and not a marketing badge, and technicians must hold the type that matches the equipment. NATE certification, issued by North American Technician Excellence, is voluntary and knowledge-based, and is the closest thing the trade has to a national competency standard. Beyond those, membership of the Air Conditioning Contractors of America signals adherence to that body's design and installation standards, and manufacturer designations such as Mitsubishi Diamond or Bosch Platinum change how warranty claims on that brand are processed.
Can I hire an HVAC company based outside Broomfield?
You can, and plenty of competent firms in Westminster, Louisville, Lafayette and Arvada work in the city regularly. The thing to establish first is administrative rather than technical: the company must hold a City and County of Broomfield contractor licence to pull your permit, and the inspection will be scheduled through Broomfield's building division regardless of where the truck is garaged. Firms that work the city weekly have that licence and know the counter; firms that reach Broomfield once a season sometimes do not, and the delay lands on you. This ranking is restricted to companies with a genuine Broomfield operating address precisely because that question stops being a question.

How to Use This List
These five are not interchangeable, and the ranking is not a verdict on workmanship. Kappler holds the deepest credential stack and the tightest north-metro service radius. Cooper brings the longest tenure, two active state registrations and the rebate machinery that comes with volume. Kraemer is the one to call when the job involves commercial refrigeration. Tico is the small-shop option with real heat pump and ventilation scope. Kerwin is a heating specialist with the best licence paper trail in the city and no cooling side at all.
Whichever you call, ask three questions before work starts: who pulls the Broomfield mechanical permit and in whose name, which technician's EPA Section 608 certification covers the refrigerant work, and whether the quote is written to the 2024 code Broomfield now enforces. Get two written estimates. A contractor who answers all three without hesitating has told you most of what the reviews cannot.
