Should I open or buy a One Hour Heating & Air Conditioning franchise in 2027?

The Real Numbers

One Hour Heating & Air Conditioning is owned by Authority Brands (alongside Benjamin Franklin Plumbing, Mister Sparky, Mosquito Squad). The brand reported 103 franchisees across 411 territories as of December 31, 2024 and ranked #159 on the Franchise Times Top 400 for 2025 systemwide sales.

The April 3, 2025 FDD is the controlling document for 2026–2027 awards. Here is the build.

Item 19 (2024 fiscal year reporting): average gross revenue per franchisee was $3,838,222, with the median around $2.4M and the top quartile north of $5.6M. Authority Brands' Item 19 covers all reporting franchisees who operated a full year — not territory-adjusted, so multi-territory operators inflate the average.

Margin reality from the operator side: a well-run residential HVAC service business runs 10–20% EBITDA, with 15–18% being the realistic target for a franchised location once royalty (6%), brand fund (2%), and tech fees flow through. High-performers in the One Hour system land 18–22% by leaning on the call center, dynamic pricing, and the StraightForward Pricing Guide (flat-rate book that lifts ticket average 12–20% versus T&M billing).

Payback math on a typical conversion:

• Year 1 gross: $1.4M (existing book) → EBITDA ~$210K → owner earnings ~$150K after debt service on a $150K SBA 7(a) at 11.25%.
• Year 2: $2.1M gross with call-center bookings layered in → EBITDA ~$340K.
• Investment payback in months 14–22 is typical for conversions; scratch builds payback in months 30–48.

Who Wins With This Business

You already own an HVAC company doing $800K–$2M and you want the lead engine, the call center, the Service America financing rails (consumer financing closes 28–34% of high-ticket sells), and the Success Academy training without rebuilding the back office. Conversions are the brand's winning archetype — the FDD discount on initial fees and the lower startup range exist precisely to recruit you.

You ran an HVAC service department at a regional player (think ARS, Service Experts, a Lennox dealer) and you have a General Manager who can be your service manager on Day 1. The system rewards operators who already know how to manage a 6–18 truck residential service fleet.

You have $250K–$400K liquid plus a home-equity backstop, can stomach the 12–18 month ramp, and your local market shows >250,000 owner-occupied single-family homes within a 30-minute drive radius with median home age >22 years (replacement window) and median household income >$78,000. These three demand variables drive >70% of territory-level variance in residential HVAC ticket volume per BLS Quarterly Census of Employment and Wages data.

You think in unit economics: average residential repair ticket is $385–$520, average system replacement ticket is $8,800–$14,500, and the operator who hits 38–44% gross margin on equipment with 8–12% labor productivity gains from dispatch optimization is the one who clears $5M+ in Year 3.

Who Loses With This Business

You have zero HVAC field experience and assume you can hire your way out of it. Residential HVAC has the highest technician turnover in the trades — 34.7% annual turnover per the Air Conditioning Contractors of America (ACCA) 2025 Workforce Study. Without an operator who reads P&Ls and walks ride-alongs, your top techs will leave for the open-shop competitor across town.

You are under-capitalized. The FDD's $143K–$286K does not include the $120K–$180K working-capital buffer you actually need to survive the first summer if your DSO blows out (consumer financing reduces this, but only after you onboard).

You overweight the brand and underweight the market. One Hour's call-center leads convert at 31–38% — strong, but if your Cost Per Lead (CPL) from local SEO and Google LSA tops $145, your customer acquisition cost (CAC) eats through the royalty's value. Markets that already have a One Hour, an Aire Serv, an ARS, and 3+ strong independents are brutal CAC environments.

You hate process discipline. One Hour mandates dispatch software (currently ServiceTitan integration), flat-rate pricing books, uniform-and-truck-wrap standards, and 15+ monthly KPIs reported to corporate. Operators who want to "run their own way" should buy an independent.

2027 Market Conditions

The federal Section 25C and 25D residential energy credits sunset for property placed in service after December 31, 2025. That pulled forward demand into late 2025 and created a soft Q1–Q2 2026 replacement market. By Q4 2026 and into 2027, the supply correction worked through and state-administered HOMES + HEAR rebate programs (funded under the IRA's $4.5B HEAR appropriation) become the primary heat-pump conversion subsidy — up to $8,000 per low-to-moderate-income household.

For franchise operators, that means three real shifts in 2027:

Lead intake is bifurcating. Emergency repair calls (the ~$385 ticket) are steady and recession-resilient — equipment breaks regardless of incentive policy. System replacements are incentive-sensitive and now require sales reps trained on state-specific rebate stacking, not federal tax-credit decks. Brands with a national call center and rapid sales-training cadence (One Hour ships updated pricing books quarterly) have a clear advantage.

Refrigerant transition pressure. The EPA AIM Act phasedown of HFCs raised R-410A system prices 18–24% in 2025, with R-454B becoming standard on new equipment. Service techs who weren't trained on R-454B handling lose callbacks and warranty work. Authority Brands rolled the training out across the One Hour network in Q2 2025; independents are scrambling.

Private-equity roll-ups continue. Service Experts (Enercare), ARS/Rescue Rooter, Wrench Group, Sila Services, and Apex Service Partners all aggressively bought independents through 2025–2026 at 6.5–8.5x EBITDA. That compressed the exit multiple gap between franchised and independent HVAC shops and made the franchise route more attractive at exit — One Hour conversions sold to PE roll-ups at 7.2–8.1x EBITDA in 2025 per industry M&A trackers.

Labor cost inflation continues. Median HVAC tech wage rose to $29.40/hour in May 2025 BLS data (OEWS code 49-9021), up 6.3% year-over-year. Operators who don't push ticket average up 8–12% lose ground every year.

The 90-Day Decision Tree

1. Days 1–10 — Run the territory check. Pull owner-occupied SFH count, median home age, and median household income for your candidate ZIP-cluster from Census ACS 5-year tables. Reject any territory with fewer than 250,000 SFH within 30 minutes unless you have a true low-competition argument.
2. Days 10–25 — Request the FDD and read Items 5, 6, 7, 11, 17, 19, 20, 21 in that order. Most candidates skim. Read Item 21 audited financials — Authority Brands is PE-owned by Apax Partners and the parent-level financial health matters because royalties get reinvested into your call center and tech stack.
3. Days 25–40 — Validate Item 19 with the franchisee disclosure list. Call 12 franchisees minimum, including 3 below the system average, 3 at the median, and 3 above the average. Ask: actual gross last year, EBITDA %, weeks to breakeven, how often corporate visits, leads per truck per week from the call center.
4. Days 40–55 — Get conditional SBA approval. Authority Brands is on the SBA Franchise Directory, so processing is faster. Target 70% SBA 7(a) + 30% cash/equity. Get quotes from at least three SBA preferred lenders (Live Oak, Newtek, Huntington).
5. Days 55–70 — Visit two existing One Hour operations. Spend a full day at each. Watch dispatch, ride one call, sit in on the morning huddle. If the franchisee refuses, that is your answer.
6. Days 70–85 — Decision gate with your spouse or business partner. Hard yes/no on: am I willing to work 55–65 hours/week for 18–24 months, can I fund $120K–$180K of working capital beyond FDD, do I trust the operator I am hiring (or am I the operator)?
7. Days 85–90 — Sign or walk. If you sign, send the Franchise Agreement to a franchise attorney first ($3,500–$6,500 review fee, non-negotiable). If you walk, the territory check work is still valuable for an independent build.

Alternative Plays

Buy an independent HVAC shop directly. Off-market deals trade at 3.5–5.5x SDE versus 6.5–8.5x EBITDA for franchised conversions on exit. If you have operator skill but want full equity upside, a $1.2M–$2.5M revenue independent with retiring ownership is the better math — no royalty, no brand fund, but no call center.

Convert an independent and then franchise. Run the independent for 18–24 months, fix the unit economics, then convert to One Hour or Aire Serv (Neighborly's competing brand, lower royalty of 5%, $40K franchise fee). You get the operating runway before paying the brand tax.

Join a PE roll-up as a regional GM. Apex Service Partners, Wrench Group, and Sila Services hire regional GMs at $180K–$280K base + 8–15% of acquisition equity. Lower risk, lower upside, no FDD.

Pick an adjacent Authority Brands concept. Benjamin Franklin Plumbing has lower startup ($110K–$240K), similar Item 19 ($1.9M average), and less head-to-head competition in many markets. Same parent, same call center, same playbook.

Buy a One Hour resale instead. Active franchisee resales post on the Authority Brands portal a few times per year. A 5-year-old unit doing $2.4M at 17% EBITDA sells for $1.4M–$1.7M, with the seller financing 20%. You skip the 18-month ramp and start cash-flowing month one.

FAQ

How much can I realistically earn in the first year? For a conversion of an existing HVAC shop, owner earnings typically range from $80,000 to $220,000 in Year 1. Scratch-built franchises often see lower or negative earnings in the first year, as they need time to build a customer base and cover startup costs.

What is the total investment range for a new franchise? A startup franchise from scratch costs between $143,273 and $286,702, while converting an existing HVAC business runs $84,570 to $204,824. These figures include the franchise fee, equipment, initial marketing, and working capital.

Do I need HVAC experience to succeed? Yes, HVAC operating experience or a strong service-business operator partner is strongly recommended. Without it, the learning curve is steep, and the risk of slower growth or financial struggle increases significantly.

How long does it take to break even? Conversions of existing HVAC companies typically break even in 14 to 28 months. Scratch-built franchises often take 30 to 48 months to reach breakeven, depending on local market conditions and lead generation speed.

What ongoing fees does the franchise charge? The royalty is 6% of gross revenue, with a minimum of $1,500 per month. There is also a brand fund fee, typically around 2% of gross revenue, which supports national advertising and marketing programs.

Can I start this franchise without an existing HVAC company? Yes, you can start from scratch, but it is riskier and slower to profitability. Most franchisees who hit the $3.8 million average revenue are conversions of established HVAC shops, not startups.

Bottom Line

Buy or open a One Hour Heating & Air Conditioning franchise if you are an HVAC operator (or have one as your full-time partner), you have $250K+ liquid plus home-equity backstop, your territory clears the SFH/age/income demand filter, and you are converting an existing book or buying a resale. The brand's average $3.8M revenue per franchisee is real, but it is earned through call-center leverage, dispatch discipline, and StraightForward Pricing, not handed out. Skip One Hour if you have no HVAC field experience, are under-capitalized, or want to run your own way without process discipline. Best play for most operators in 2027: buy an active resale doing $2M+, skip the 18-month ramp, and start compounding immediately.
