What an HVAC estimate should include
A new system is one of the bigger bills a household pays, and the client will probably compare your estimate with someone else's. Your lines should make that comparison easy and fair to you.
- The equipment, named and sized. "3-ton 16 SEER2 heat pump system, matched air handler" lets the client compare like with like. When one quote gives tonnage and efficiency and another just says "new system", the vague one is harder to trust.
- Line set and disconnect on their own line. Some installers reuse the old line set. The example replaces it for $680, and listing it explains part of any price gap between quotes.
- The thermostat, installed and set up. It's the part of the system the client touches every day. A separate line also lets them remove it if they already own one they like.
- Removing the old equipment. Haul-away and recycling is $175 in the example. Leave it off and you'll have the "you're taking that with you, right?" talk on install day.
- The permit as a line. The example includes a mechanical permit. Whether one is needed and what it costs is set locally, so check with your city or county.
- Exclusions that match the usual surprises. Ductwork replacement, electrical panel upgrades and drywall repair are all out of scope here. If the install turns up leaky ducts or a full panel, it becomes a separate price instead of an argument.
- A short validity and a deposit. Equipment prices move, so the example holds the price for 15 days and asks for 25% to order the system.
The notes say manufacturer rebates, if any, are the customer's to claim. Rebate and tax credit programs change and have their own rules, so point the client to the program itself rather than promising an amount on your estimate.
How to write an HVAC estimate
- Size the system before you price it. Do a load calculation or a careful walk-through, and write the size on the estimate. A photo of the old unit's data plate helps when you build the quote later.
- Offer two options if the client is shopping around. A standard system and a higher-efficiency one, with every other line the same, let the client choose without calling a third company.
- Describe install day. Say how long the house will be without heating or cooling, whether you need attic access, and where the new disconnect will go.
- Say what happens if you find more work. A line like "duct sealing, if needed, quoted separately after inspection" sets up a change order before it's needed.
- Match the validity to your supplier. If your distributor's prices change often, a 15-day estimate keeps you from installing at last month's cost.
- Collect the signature and the deposit together. The client signs on your phone in TapBill, and after the install one tap turns that estimate into the invoice.
Use this hvac estimate template
For service calls, the HVAC invoice template shows a capacitor and contactor repair billed line by line. Big installs often touch other trades: see how the electrical estimate prices a panel upgrade and how the roofing estimate handles damage nobody can see yet, or build your own in the estimate generator.
Frequently asked questions
What should an HVAC estimate template include?
Your business details, the client and the service address, an estimate number and date, then equipment, materials, labor and fees as separate lines. Below them go the exclusions, how long the price is good for and the deposit. The example on this page has all of these.
How long should an HVAC quote be valid?
Short enough that a supplier price change doesn't eat your margin. The example uses 15 days. If the client signs after it expires, check your equipment cost again before you confirm the date.
Should I put the equipment brand on the estimate?
If you know what you'll install, yes. A brand and model let the client look up the unit and compare quotes fairly. If supply is uncertain, write "or equivalent" and say what that means, such as the same tonnage and efficiency.
What if I find a ductwork problem during the install?
Stop and show the client before you do extra work. Write a change order with the new lines and price, and get it approved the same way the original estimate was approved.
