How to Price HVAC Jobs

Start with your cost per billable hour

Every price in an HVAC book, from a capacitor swap to a full system, rests on one number: what it costs you to put a tech in front of a customer for an hour. The wage is only the start. The Bureau of Labor Statistics reports a median wage of $29.33 an hour for heating, air conditioning, and refrigeration mechanics and installers in May 2025 ¹. On top of the wage you carry payroll taxes, workers' comp, the van, fuel, gauges and recovery equipment, dispatch, and the hours no customer pays for: drive time, supply house runs and callbacks.

Two HVAC realities to build in:

• Seasonality. If your calls drop off in spring and fall, divide your yearly costs by the hours you actually bill across the whole year, not by what a busy July week looks like.
• Truck stock. Capacitors, contactors and motors sitting on a van tie up cash, and some go missing. Your parts markup has to cover that.

The full method is in how to set your labor rate, and markup vs margin explains why the percentage you add to cost is never the percentage you keep.

Flat rate or time and materials for service work

Use flat rate for repairs you do over and over, and time and materials for work nobody can predict.

Many HVAC repairs are familiar tasks: replacing a capacitor, contactor, igniter, flame sensor or blower motor, or clearing a clogged condensate drain. Because you do them constantly, you know how long they take, which is what flat-rate pricing depends on. The customer approves a fixed price before you start, and an efficient tech earns the company more, not less.

Build each flat-rate task from three numbers:

1. Book time. Realistic time on site for that task, including setup, testing after the repair and cleanup. Use your average tech, not your fastest.
2. Your hourly billing rate. Your cost per billable hour plus profit.
3. Parts at cost plus your parts markup.

Example: Your book time for a task is 1 hour, your billing rate is $150 an hour, and the part costs you $50, which you mark up 100%. The task price is $150 for labor plus $100 for the part: $250, whether the repair takes 40 minutes or 80.

Add variants where the time genuinely differs: a blower motor on a basement furnace and one on an attic air handler in July are different jobs.

Time and materials fits work where the time can't be known up front: leak searches, intermittent faults, duct modifications and older equipment that needs parts hunted down. Quote an hourly rate with a not-to-exceed cap, and get approval before you go past it.

Diagnostic and service-call fees

Set the diagnostic fee to cover a complete visit, because some calls end without a repair to sell.

A no-cool call might be a failed compressor or a tripped breaker. When it's the breaker, the fee is all the revenue the visit produces, so it has to pay for the truck roll, the tech's time and the office work behind the dispatch.

Example: If an average service visit costs you $120 to run, a $50 diagnostic fee loses $70 every time the fix turns out to be a thermostat setting. A fee at or above your visit cost means those calls break even.

Rules that keep the fee from becoming an argument at the door:

• State it when the call is booked and again in the appointment confirmation, including whether it's credited toward an approved repair.
• Pick one credit policy. Crediting the fee helps close repairs, but then your flat-rate prices must carry the visit cost. Not crediting it lets repair prices stay lower. Either works if it's consistent.
• Give the repair price before you start. The fee buys a diagnosis and a firm price. The repair is a separate yes.

After-hours and emergency rates

Decide the after-hours premium in advance, define exactly when it applies, and tell the customer before the truck rolls.

The premium pays for real costs: on-call pay, a disrupted schedule the next morning, and overtime. Under the Fair Labor Standards Act, covered non-exempt employees must be paid at least one and one-half times their regular rate for hours over 40 in a workweek ². If a 10 p.m. no-heat call lands on a tech who already has 40 hours that week, every hour of it costs you half again in wages. Check your state's wage rules as well.

Choose one structure and put it in your booking script:

• A higher after-hours diagnostic fee, with repairs at standard book prices. Easy to explain on the phone.
• A multiplier on the flat-rate book after hours. Covers long repairs better, but harder to explain.

Then define the window precisely (weeknights after a set time, weekends, holidays) and give the caller a choice. Someone with no cooling on a mild evening may be glad to take the first slot tomorrow at standard rates; save the premium for true emergencies like no heat in freezing weather. And keep your rates steady through heat waves and cold snaps. Customers remember who answered at the posted price.

Size the system before you price it

Equipment is usually the biggest line on a replacement quote, and its size should come from a load calculation, not from the label on the old unit.

ACCA's Manual J is the ANSI-recognized procedure for calculating a home's heating and cooling loads, and Manual S covers choosing equipment to meet those loads using the manufacturer's performance data ³. The 2024 International Residential Code, section M1401.3, requires heating and cooling equipment to be sized under Manual S (or another approved method) based on loads calculated under Manual J (or another approved method) ⁴. Whether that applies to a given job depends on the code edition your state or city adopted and how it's enforced, so ask your building department what it expects with a permit application.

Why sizing is a pricing decision, not just an engineering one:

• Size sets your equipment cost. The old unit may have been oversized from the start, or the house may have new windows, insulation or an addition. If the Manual J load calculation shows a smaller system fits, your equipment cost drops and you can price competitively without cutting margin.
• Oversizing creates callbacks. DOE notes that oversized equipment means lower efficiency, more wear and, for air conditioners and heat pumps, higher indoor humidity in summer ⁵. Comfort complaints and service calls on a new install eat the margin you priced in.
• It finds hidden work early. If the right system needs more airflow than the existing ducts can deliver, the duct changes belong in today's price, not in a change order next month.

Budget the time a load calculation takes into every replacement price.

Build the replacement price

List every cost before you set a price:

• Equipment: outdoor unit, indoor coil, furnace or air handler, at your distributor cost.
• Installation materials: line set (or a flush if you reuse the old one), pad, disconnect and whip, thermostat, condensate parts, fittings and any refrigerant beyond the factory charge.
• Labor: crew hours at your loaded labor cost, including commissioning (charge, airflow and safety checks) and the customer walkthrough.
• Permit and inspection: where required (rules vary by state and city), the fee plus the time to pull it and meet the inspector.
• Removal: recovering refrigerant from the old system and hauling the equipment away.
• Site-specific extras: electrical work, duct transitions, a new return, a condensate pump, attic or rooftop access.
• Overhead and profit: the share of rent, office staff, marketing, vehicles and warranty callbacks this job has to carry, plus profit.

Then price to a target gross margin instead of adding a flat markup, because on an equipment-heavy job the gap between the two adds up fast.

Example: A straight-swap AC and coil replacement has $4,200 in equipment, $700 in materials, $800 in labor (two installers for 8 hours at $50 an hour loaded) and $300 for the permit and disposal: $6,000 of direct cost. To reach a 40% gross margin, divide by 0.60: $6,000 ÷ 0.60 = $10,000, which leaves $4,000 for overhead and profit. A 40% markup would give $8,400 instead, a 28.6% margin and $1,600 less for the same work.

Your own overhead decides the right target margin, so take it from your numbers, not from a rule of thumb.

Good, better, best: tiers built on efficiency

Offer options that differ in efficiency and features, never in size, and price each tier on its own costs.

Good-better-best pricing suits replacements because the equipment genuinely comes in tiers. The floor is set by DOE. Since January 1, 2023, split-system central air conditioners must meet 13.4 SEER2 in the North and 14.3 SEER2 in the Southeast and Southwest (13.8 SEER2 at 45,000 Btu/h and above), with added EER2 minimums in the Southwest, and split-system heat pumps must meet 14.3 SEER2 and 7.5 HSPF2 nationwide ⁶. Check which DOE region your state is in, because your entry tier can't go below its floor. The SEER2 entry explains the rating itself.

A practical way to build the three:

• Good: a reliable single-stage system at or modestly above the regional minimum, with your standard labor warranty.
• Better: a higher-SEER2 two-stage system, an upgraded thermostat, and a longer labor warranty or a first year of maintenance.
• Best: a variable-speed system near the top of the manufacturer's line, its matching controls and your longest labor coverage.

Rules that keep tiers honest and profitable:

• One load calculation for all three. Tiers change efficiency and features, not capacity.
• Same target margin on every tier. The bottom tier is a real option, not a loss leader you hope to upsell from.
• Price the labor differences. Variable-speed systems with communicating controls can take longer to set up and commission.
• Describe ratings, not promises. Show the efficiency ratings, and don't promise bill savings you can't guarantee. If you mention rebates or tax credits, confirm the program is open and the equipment qualifies, and present them as conditional.

Example: Using the $1,800 of non-equipment cost from the example above and the same 40% target margin:

• Good: $4,200 equipment, $6,000 total cost, priced at $10,000.
• Better: $5,400 equipment, $7,200 total cost, priced at $12,000.
• Best: $7,500 equipment plus $300 of extra setup labor, $9,600 total cost, priced at $16,000.

How to lay the options out on paper is covered in how to write an HVAC estimate.

Refrigerant: price it by the pound, at today's cost

Refrigerant prices can move quickly during the HFC phasedown, so keep refrigerant out of anything with a fixed price.

Under the AIM Act, EPA is stepping down U.S. production and consumption of HFCs: 40 percent below the historic baseline from 2024 through 2028, 70 percent from 2029 through 2033, 80 percent in 2034 and 2035, and 85 percent from 2036 on ⁷. EPA's own 2026 rulemaking describes the AIM Act as "inherently inflationary," because cutting HFC supply raises prices for goods and services that rely on HFCs ⁸. Newer refrigerants have had their own swings: EPA said supply chain problems in spring and summer 2025 caused shortages, price spikes and stockpiling of R-454B in the residential market ⁹.

The rules for new equipment moved too. New residential and light commercial AC and heat pump systems are held to a refrigerant global warming potential (GWP) limit of 700, but a final rule EPA issued on May 26, 2026 removed the installation deadline for systems above that limit that were made or imported before January 1, 2025, so that inventory can be installed until it runs out ^{8 10}. EPA proposed the change to let existing R-410A equipment sell through after the 2025 shortages ⁹. While that stock lasts, you may quote both kinds of system. Price each from its own current equipment and refrigerant cost rather than a blended number, and name the refrigerant on the quote.

For older systems, no new R-22 has been made or imported in the U.S. since January 1, 2020. Service depends on recovered, recycled or reclaimed supply, and EPA cautions that its price and availability may change ¹¹. When an R-22 system needs a major leak repair and a full charge, put a replacement option next to the repair price so the customer can compare.

Practical rules for your price book:

1. List refrigerant as its own line, priced per pound, separate from the flat-rate task that uses it.
2. Update the per-pound price whenever your supplier's price changes, not at the annual price book review.
3. Put a stated validity window on replacement quotes, so a quote accepted months later doesn't lock in old equipment and refrigerant costs.
4. Keep refrigerant out of maintenance agreement prices and charge for it when it's used.

Maintenance agreements: price the visits, then the promises

Price a service agreement from what it costs to deliver: the visits, the materials and every benefit you promise.

• Visits: on-site time plus drive time, per system rather than per house. A home with separate upstairs and downstairs systems is two systems' worth of work.
• Materials: filters if included (define the sizes and types, since their cost varies), plus any supplies you use on every visit.
• Benefits: priority scheduling in peak season, repair discounts, a waived diagnostic fee, a reduced after-hours fee. Each one costs money, so estimate it from your own job history.

Example: An agreement includes two visits a year at 1.5 hours each, drive time included, and a tech-plus-truck cost of $80 an hour: $240. Filters and supplies add $20. A 15% repair discount, if the average member buys $200 of repairs a year, costs $30. Billing and scheduling add $10. That's $300 of cost. Priced for a 25% margin, $300 ÷ 0.75 = $400 a year, or about $33 a month.

If that looks high next to other plans in your market, look at when the visits happen before you cut the price. If your spring and fall weeks are slow, visits booked then use tech hours you're already paying for, which is a fair reason to price them on a lower labor cost. Visits squeezed into peak weeks push out paying repair calls and should be priced at full cost. Re-price at each renewal.

Check your prices against finished jobs

A price book is a set of assumptions until finished jobs confirm it. After each replacement, compare estimated and actual crew hours, materials and callbacks. If installs keep running long, raise the book hours instead of absorbing the difference. Track callbacks by repair task too: a task that keeps coming back under your labor warranty is underpriced, under-diagnosed or both. Review labor rates and book times at least once a year, and whenever wages, insurance or overhead change.
