Free HVAC Estimate Template (Good, Better, Best)

A homeowner whose AC just quit isn't comparing efficiency charts. They want to know three things: what are my options, what does each one cost, and which one should I pick?

This HVAC estimate template answers all three on one page. It shows good, better and best options side by side, each with its equipment, efficiency, warranty and its own total, calculated for you in the Excel and Google Sheets versions. The customer circles one and signs.

No email required. In the Excel file, everything in blue is yours to fill in. Everything in black calculates on its own.

What's in this HVAC estimate template

• Three options side by side: Good, Better and Best columns.
• What the customer actually compares: system, efficiency (SEER2 and AFUE), thermostat and warranty for each option.
• Price lines per option: equipment, installation labor, materials, permit and disposal, ductwork. Each column totals on its own.
• Discount or rebate per option, one tax rate for all, and an option total.
• An optional maintenance plan price, and an "option chosen" line the customer circles.
• Notes for what's included, rebates and exclusions, plus a signature line.

Only quoting one system or a repair? Fill in the Good column and delete the other two.

Why good, better, best works

When you give one price, the customer's only choice is yes or no, and "no" often means calling another contractor. With three options, the question becomes which one. Customers feel in control, and many choose the middle option because it feels like the sensible balance between price and quality.

How to build the three:

• Good: a reliable, standard-efficiency system that solves the problem at the lowest sensible price.
• Better: higher efficiency, a smart thermostat and a longer warranty. Usually the one you'd recommend.
• Best: top efficiency and comfort features, like variable-speed equipment and the longest labor warranty.

Keep the differences easy to see. If the customer can't tell why Better costs more, they'll pick Good.

How to estimate an HVAC replacement (step by step)

1. Size the system properly. Don't just copy the old unit's size. A load calculation (for example, Manual J in the US) gives you the right capacity for the house.
2. Check what the install needs: ductwork condition, electrical, the line set, the pad, venting for the furnace.
3. Price the equipment for each option. Use your real supplier prices plus your margin.
4. Add labor, materials, permit and disposal. These are the lines most often left out of a quick quote.
5. Note rebates and credits carefully. High-efficiency systems may qualify for utility rebates or tax credits. Programs change often, so say "may qualify" and help the customer check rather than promising an amount.
6. Offer a maintenance plan. Two tune-ups a year keeps the new system running and keeps you in touch with the customer.

HVAC estimate example

Replacing a central AC and gas furnace (example prices only, since costs vary a lot by region and equipment):

Optional maintenance plan: $189 a year.

Repair or replace?

Not every call is a replacement. When the customer is deciding between repairing and replacing, put both on the estimate: the repair in one column, a replacement option or two next to it. Mention the age of the system, how often it has needed repairs and what a new one would save in energy, and let them decide.

What to say to customers

When you send it:

Hi [name], here are your three options for the new system. Most of my customers choose [Better]: it [main benefit] and comes with [warranty]. All three include removal of the old equipment, permit and a start-up test. Happy to talk through it on the phone.

Follow-up the next day:

Hi [name], just checking in on the system options. I can install as soon as [day]. If it would help, I can also check which rebates you might qualify for.

Write it faster with AI

After the visit, record a voice note: house size, current system, problems, what you'd recommend. Turn it into text and paste it into an AI assistant (ChatGPT, Claude, Gemini or Copilot) with this prompt:

Turn my notes into an HVAC estimate for [customer name] with three options (good, better, best). For each: the system, efficiency, thermostat, warranty and one sentence on who it's best for. Then what's included, what's not and when I can install. Plain English, friendly tone. My notes: [paste]

Copy the options into the template so the totals calculate. AI drafts, you decide.

Frequently asked questions

What should an HVAC estimate include?

The equipment (brand, model, size and efficiency), installation labor, materials, permit, disposal of the old unit, warranty, what's not included and how long the price is valid. Showing two or three options makes it easier for the customer to choose.

Should I show the customer three options?

For replacements, it usually helps. Three clear options turn "yes or no" into "which one," and let the customer pick the level of comfort and efficiency they want.

How long should an HVAC estimate be valid?

30 days is common. Equipment prices and availability change, so an expiry date protects you.

Should HVAC estimates be free?

Most contractors give free estimates for system replacements. Diagnostic visits for repairs are often charged and credited toward the repair if the customer books.

Can I use this HVAC estimate template in Google Sheets?

Yes. Use the Google Sheets link above to make your own copy, or upload the Excel file to Google Drive and open it with Google Sheets. The formulas work in both.
