What Brennan Heating & Cooling does
Brennan Heating & Cooling Inc. is a privately held, family-owned HVAC services company founded in June 1990 by Billy Brennan and joined by his brothers Dave and Pat in the early 1990s, tracing its sheet-metal trade roots to their father Bill Brennan Sr.'s B&B Heating business established in 1977. The company is headquartered at 815 21st St NW in Great Falls, Montana, and operates as a small local contractor (1-10 employees) serving Great Falls and surrounding Montana communities. It provides heating, cooling, ventilation, and indoor air quality solutions across both residential and commercial segments, with notable commercial projects including courthouses and hospitals.
The product and service portfolio spans Heil forced-air heating and cooling systems, Mitsubishi and Fujitsu mini-split ductless systems, Honeywell controls and thermostats (including programmable and Wi-Fi models), electrostatic air filters, air-to-air exchangers, humidification systems, and garage unit heaters. A key differentiator is in-house custom sheet metal fabrication using galvanized metal, copper, and other materials, which supports ductwork for both small residential and large commercial installations. The company is licensed for gas piping, fully insured and bondable, and offers a 1-year labor and parts warranty. Three owner-brothers hold mechanical engineering and HVAC design degrees from Northern Havre, Montana State University, and Dunwoody Institute, and personally lead design, estimating, and installation work.
The business model is a hybrid of one-time installation revenue (residential and commercial system replacements, upgrades, and new construction), project-based service and repair fees (including after-hours emergency calls and diagnostic charges), and recurring warranty/maintenance streams. Go-to-market is sales-led via direct field sales, phone-based intake at (406) 452-1133, free residential estimates in Great Falls, and a bid-based commercial sales process. Marketing is modest and organic, relying on SEO-optimized service pages, a blog of seasonal HVAC tips, and a Facebook page for customer engagement. Pricing is quote-based and not publicly disclosed.

Brennan Heating & Cooling competitors and assessment
Company assessmentRegional players
- Cool Today: Regional multi-location residential HVAC, plumbing, and electrical services company operating across the southeastern U.S. Comparable as a sales-led residential HVAC replacement and service provider with a similar local-brand, multi-truck operating model.
Broad incumbents
- Carrier Global: Global HVAC equipment manufacturer with a significant North American service and replacement network through Carrier dealers. Brennan installs Heil (a Carrier brand) systems, so Carrier is both a critical supply partner and a broader incumbent whose dealer network competes for the same replacement and service dollars.
- Lennox International: HVAC equipment manufacturer with a North American dealer network serving residential and light commercial customers. Comparable to Brennan as an upstream equipment brand whose local dealers compete for the same residential replacement and service contracts in Montana.
- Trane Technologies: Global HVAC manufacturer operating a dealer-driven residential and commercial service network. Directly comparable to Brennan as a competitor for commercial and residential replacement projects, particularly on larger bids where Trane-affiliated dealers may have brand and financing advantages.
- ARS / Rescue Rooter: Large national provider of HVAC, plumbing, and indoor air quality services for residential customers. Comparable to Brennan as a broad-services home-comfort operator offering installation, service, and repair, though at much greater scale and geographic reach.
- ServiceMaster: National provider of residential and commercial services including restoration and home-comfort-adjacent offerings. Comparable as a large, brand-driven services company that competes for local customer mindshare and trade-allied labor in Montana markets.
Direct peers
- One Hour Heating & Air Conditioning: National franchise network of residential HVAC service and replacement contractors. Directly comparable to Brennan in that both operate as local, owner-operated residential HVAC service businesses installing premium equipment, with a similar sales-led, free-estimate GTM motion.
Others
- R.E. Michel Company: Wholesale distributor of HVAC products, parts, and controls serving contractors across the U.S. Comparable to Brennan as an HVAC supply ecosystem participant whose product mix and pricing directly influence the company's installed-system economics and equipment sourcing.
- Johnstone Supply: Wholesale distributor of HVAC, refrigeration, and plumbing parts and equipment to contractors. Comparable as a supply-chain counterparty for Brennan, and a useful proxy for the cost structure and equipment availability that shape Brennan's installation economics.
- HomeServe: Provider of home repair plans and emergency HVAC/plumbing/electrical service contracts to homeowners. Adjacent to Brennan as a recurring-revenue, subscription-based player that can either complement (warranty partner) or compete with the company's own maintenance subscription stream.
