Same work, lower price. This is the cleanest savings signal when material scope and verification conditions remain comparable.
Phoenix HVAC quote comparison
Compare HVAC quotes without letting the scope move.
Two prices become useful only after the equipment, included work, warranties, exclusions, and final-price conditions are visible on the same page. Use this worksheet to separate a real price difference from a scope difference.

Normalize before you rank
A quote can be lower for three very different reasons.
Different work, lower price. The option may still be good, but the homeowner must decide whether the omitted or changed scope is acceptable.
Unclear work, lower price. Treat the apparent savings as unverified until the missing equipment, labor, exclusion, or adjustment field is resolved.
Lock the cash totals.
Write down each all-in cash price before considering monthly payments. Keep rebates, financing terms, dealer fees, and tax assumptions on separate lines.
Mark every field same, different, or unknown.
Never convert an empty cell into “included.” An unknown field is a clarification request, not permission to assume the best case.
Price the difference only when evidence supports it.
Some differences affect cost; others affect comfort, efficiency, warranty, timing, or risk. Record the tradeoff instead of inventing a dollar adjustment.
Choose the best comparable value.
Rank only the options that are decision-ready. The cheapest incomplete proposal should not outrank a complete proposal by default.
Side-by-side worksheet
Put both written proposals on one decision surface.
Fill in what each contractor actually wrote. The worksheet is a private scratchpad on this page: entries are not submitted or saved. Use “unknown” when the proposal does not answer the field.
| Decision field | What to record | Quote A | Quote B |
|---|---|---|---|
| All-in cash price | Price before financing; note rebates separately | ||
| System type | Split AC, heat pump, packaged unit, or another configuration | ||
| Outdoor equipment | Manufacturer and complete model number | ||
| Indoor equipment | Coil, air handler, and furnace when included | ||
| Capacity and efficiency | Nominal capacity, SEER2, EER2, and HSPF2 when relevant | ||
| Removal and disposal | Existing equipment, refrigerant handling, and cleanup | ||
| Installation scope | Electrical, drain, line set, pad or roof work, thermostat, ducts | ||
| Permits and inspections | Who decides, obtains, pays, and closes them | ||
| Warranty coverage | Manufacturer parts, labor, workmanship, and registration duties | ||
| Timing | Earliest installation, expected duration, and quote expiration | ||
| Exclusions and allowances | Work or materials not included in the headline price | ||
| Price-change conditions | Site findings that can change the written amount |
Decision gate: if a material row remains unknown, the proposals are not ready for a final price ranking.
Use my quote as the market barRead the result
End with a comparability decision, not a prettier spreadsheet.
The material fields match or have documented acceptable differences.
Price can now carry more weight because the scope, equipment, coverage, and adjustment conditions are visible.
The options differ, but the homeowner can value the differences.
Keep the tradeoffs explicit. A lower price may still win, but not because a material difference disappeared from the analysis.
A missing or moving field can still change the outcome.
Request written clarification before ranking. Do not manufacture precision with a generic cost allowance or an unsupported assumption.
Verification sources
Use the proposal for commitments and authoritative records for checks.
Permit assumptions
The City of Phoenix lists like-for-like air-conditioner replacement as permit-exempt when size, capacity, and location do not change. If a proposal changes those conditions or includes related work, record who determines and handles the applicable requirements.
City of Phoenix residential guidance ↗Contractor record
Use the Arizona Registrar of Contractors search to verify the current public license record. Record the exact contractor identity on each proposal instead of assuming a brand name or salesperson identifies the licensed entity.
Arizona Registrar of Contractors ↗Matched-system performance
ENERGY STAR defines SEER2, EER2, and HSPF2 as system performance measures. The AHRI directory can help verify certified combinations; a single outdoor-unit model or efficiency number is not the entire installed-system comparison.

Common questions
Keep the comparison honest.
What is the first number to compare on two HVAC quotes?+
Start with each proposal's all-in cash price, not the monthly payment. Then hold equipment and installation scope constant. Financing terms, rebates, exclusions, and allowed price adjustments belong in separate lines so they do not hide a scope difference.
Can two quotes be comparable when the brands are different?+
Potentially. Brand is only one field. Compare system type, capacity, matched indoor and outdoor components, efficiency, model tier, controls, installation scope, warranties, timing, exclusions, and verification conditions before deciding whether the options are materially comparable.
How should I handle an item that appears on only one quote?+
Do not automatically delete it or assume the other contractor included it. Mark the item as different or unknown, ask both contractors to clarify it in writing, and decide whether it changes price, performance, risk, or homeowner effort.
Should I compare HVAC financing by monthly payment?+
A payment is not enough. Record the cash price, financed amount, term, interest rate, total of payments, dealer fees or discounts, and rebate assumptions separately. This keeps the equipment and installation comparison from being distorted by financing structure.
