How to read an HVAC quote.

You're about to spend $15,000–$30,000 on a home comfort system, and the contractor is handing you a single sheet of paper with a number at the bottom and a signature line. Let's make sure you actually know what you're buying.

1. Model numbers: if it's not on the quote, walk

A quote should list the exact outdoor condenser model, exact air handler or coil model, and the AHRI match certificate number that proves they're rated together. “16 SEER heat pump” is not a model number. If the contractor won't give you the specific model, they're reserving the right to substitute cheaper equipment later. Red flag.

2. Tonnage should match a Manual J

Ask: “How did you calculate the tonnage?” The answer should mention Manual J or a load calculation that considers insulation, windows, and air infiltration. “It replaces your old 4-ton” is not a calculation. Neither is “1 ton per 500 sqft.” Both mean the contractor didn't size your system for your home — they sized it for their spreadsheet.

3. Labor scope: permits, haul-away, commissioning

Every legitimate Florida HVAC install requires a permit pulled from the local building department. If the quote doesn't list a permit line item, the contractor is planning to skip it — which voids manufacturer warranties and can haunt you at resale. Same for haul-away (removal of your old equipment) and commissioning (verifying charge, airflow, and system performance after install).

4. Warranty terms in specific years

“Manufacturer warranty included” is meaningless. You need: equipment warranty (usually 10 years parts from the manufacturer), labor warranty (usually 1–2 years standard, or 10 years premium), and whether either is transferable if you sell the home. Our 10-year parts + labor warranty is transferable — most competitors' aren't.

5. Final price: rebates in, financing not yet applied

The number that matters is final price after rebates, before any financing. Contractors love to show a “$180/mo” headline and bury the total. Multiply the monthly by the term to see the real number. If the contractor also reports a “rebate” that's actually a financing promotion (“save $2,000 when you finance”), it's not a rebate — it's a discount that only exists if you take the loan.

6. Cancellation and refund policy

Florida law gives consumers 3 days to cancel any door-to-door sale, but a quote signed in an office doesn't automatically qualify. Ask explicitly: “What happens if I cancel tomorrow? What if equipment is already ordered? What if I cancel on install day?” A contractor who hesitates on any of these answers is not the one. A contractor who won't put the answer in writing is absolutely not the one.

The 3 biggest red flags

1. “Limited-time discount” pressure.If the quote expires in 24 hours, it's not a real quote. HVAC equipment costs don't change in a day.
2. No permit line item. This means the work will be unpermitted, which voids warranties and risks a buildings-department red tag on your home.
3. No written cancellation terms.Everything you agreed to verbally is worthless if it's not on the paper you're signing.
