HVAC quote comparison

Put HVAC equipment, duct work, controls and commissioning beside each quoted price.

Start with the questions below. Written quotes are required to compare totals; this page does not estimate a market price.

Check what each quote includes

Leave anything unclear as “Ask.” Choose “Extra” to add a separately priced item to that quote’s budget. Do not also put it in the general left-out costs below.

Equipment and design

Record the matched equipment, capacity and design documentation offered with the quote. Compare the same intended rooms and service.

Ducts and distribution

Separate existing-duct reuse, new ducts, line sets, registers, insulation and balancing.

Electrical and controls

Identify circuit, disconnect, controls and thermostat work and who completes each part.

Removal and access

Include old equipment removal, access, lifting, disposal and any roof or wall opening repair.

Commissioning and handover

Ask what installation checks, commissioning records, manuals and operating instruction are included.

Permits, warranty and exclusions

Keep inspections, labor coverage, maintenance conditions and excluded repairs in writing.

Put your quotes side by side

Add only costs left out of each written quote.

Quote A
Costs outside the quote & your reserve

This is money you set aside. It is not a contractor charge or a recommended percentage.

Quote B
Costs outside the quote & your reserve

This is money you set aside. It is not a contractor charge or a recommended percentage.

Enter a quoted price

A price difference helps only after the work matches.

Nothing is sent to a contractor. Saving keeps these entries in this browser; downloading makes a text file.

Before asking for a price

Keep the contractor’s sizing/design basis, equipment model numbers, indoor and outdoor locations and duct or pipe scope together. This worksheet does not size equipment.

What the total can tell you

An employee wage is not an installed HVAC rate. Equipment, design, access, distribution and business costs vary; compare your written scopes and prices.

The budget adds the quoted price, separately priced Extra items, other costs left out and any tax not already included. Your chosen reserve is added to that subtotal. Treat every “Ask” row as work that is not yet confirmed as included. Get the answer in writing before comparing totals.
