HVAC businesses make money in three different ways — replacements, service repairs and maintenance plans — and each one needs its own pricing approach. This guide covers all three, plus how to size equipment properly and where steady local work comes from.
1. Start with your true cost per hour
HVAC trucks are expensive to run: stocked parts, recovery equipment, gauges, licences, insurance and training add up. Count it all.
Your billable hours in HVAC are often low because of drive time, call-backs and seasonal swings — busy in the first heat wave and cold snap, quiet in spring and fall. Maintenance plans are how you fill the quiet weeks (see section 4).
2. Replacements: size it right, then price the whole system
Never size a furnace or air conditioner from the old unit or a "square feet per ton" rule of thumb. Oversized equipment short-cycles, wastes energy, and leaves rooms clammy; undersized equipment can't keep up. Do a proper room-by-room heat-loss / heat-gain load calculation (in North America, the ACCA Manual J method is the common standard, and many jurisdictions require one for permits). Then check that the ducts can actually move the airflow the new equipment needs.
Then quote the whole system, not just the box:
| Item | Qty | Rate | Amount |
|---|---|---|---|
| High-efficiency gas furnace, supplied & installed | 1 unit | $4,850.00 | $4,850.00 |
| Central A/C, 2.5 ton — sized by load calculation | 1 unit | $4,200.00 | $4,200.00 |
| New line set, pad & disconnect | 1 job | $690.00 | $690.00 |
| Venting, gas connection & condensate drain | 1 job | $520.00 | $520.00 |
| Smart thermostat, installed & set up | 1 unit | $285.00 | $285.00 |
| Permit & inspection | 1 job | $220.00 | $220.00 |
| Remove & recycle old equipment | 1 job | $175.00 | $175.00 |
| Subtotal | $10,940.00 | ||
| Tax (13% — use your own local rate) | $1,422.20 | ||
| Total | $12,362.20 | ||
Equipment size comes from a room-by-room load calculation — not from the old unit or the square footage.
Example numbers only — prices vary a lot by area, season and job. Use your own costs.
Give options with clear differences
Offer two or three packages — for example a standard-efficiency system, a high-efficiency system and a premium variable-speed or heat-pump option — and explain the difference in comfort, running cost and warranty in plain language. If government or utility rebates apply in your area, list them, but don't promise amounts you can't confirm.
3. Service calls: flat-rate beats hourly
Homeowners hate open-ended hourly bills. A flat-rate price book — a set price per repair that already includes your labour, the part and your margin — lets the customer approve the price before you start and protects you when a job takes longer than expected.
| Item | Qty | Rate | Amount |
|---|---|---|---|
| Diagnostic visit | 1 visit | $129.00 | $129.00 |
| Replace flame sensor (flat rate, parts & labour) | 1 repair | $189.00 | $189.00 |
| Subtotal | $318.00 | ||
| Tax (13% — use your own local rate) | $41.34 | ||
| Total | $359.34 | ||
Example numbers only — prices vary a lot by area, season and job. Use your own costs.
Build each flat rate from: average time for the repair × your hourly rate, plus the part cost with your parts margin, plus a small allowance for the truck stock you carry. Review the book every season as part prices change. On Genie on-demand jobs you can send an itemized on-site repair quote that the client approves and signs on their phone before you start the repair.
4. Maintenance plans: recurring revenue
A maintenance plan — for example a spring A/C tune-up and a fall furnace check for a yearly or monthly fee — gives you predictable income, fills slow seasons and puts you first in line when the system needs replacing. Price it so each visit covers your time at your hourly rate, then add perks that cost you little: priority booking, no diagnostic fee, a small discount on repairs.
5. Where local HVAC jobs come from
- Seasonal reminders. Remind past customers before heating and cooling season. A short message with a booking link fills your calendar before the rush.
- Ageing equipment. Systems past 15 years are replacement candidates. Note the age on every service call and follow up kindly — no scare tactics.
- Real-estate and property managers. Home sales and tenant turnovers need quick furnace checks and repairs.
- Reviews. A five-minute "how did we do?" message after each visit builds the reviews that win the next job.
- Genie. Take on-demand service jobs and claim local install projects you want — clients see your profile, reviews and itemized quote.
