7 Questions to Ask a Heat Pump Installer Before You Sign Anything
Quick answer
Before signing, ask every heat pump bidder: (1) Will you do a Manual J load calculation? (2) Are you enrolled in my state's rebate program? (3) What's the unit's capacity and COP at 5°F? (4) What exactly does the quote include? (5) Who handles permits and commissioning? (6) What are the labor and equipment warranties? (7) Can you show references for similar installs? A contractor who answers all seven confidently is worth a premium.
1. Will you perform a Manual J load calculation?
This is the industry-standard room-by-room heating/cooling load analysis. Contractors who size by square-footage rules of thumb routinely oversize by 30–50%, which raises your price and causes short-cycling. If the answer is anything other than yes, keep shopping.
2. Are you enrolled in my state and utility rebate programs?
In 2026, most major rebates (state Home Energy Rebates, utility incentives) are applied at point of sale by enrolled contractors. A non-enrolled contractor can cost you thousands in unclaimable incentives regardless of their bid price.
3. What is this unit's capacity and COP at 5°F?
Anyone selling in a cold climate should know these numbers without looking them up. Capacity retention of 70%+ at 5°F and COP around 2 is the modern bar. If they answer with SEER only, they're quoting you a cooling appliance.
4. What exactly is included — and what isn't?
- Electrical work and any panel changes
- Duct modifications, sealing, or new returns
- Condensate management and outdoor mounting/stand
- Thermostat/controls and configuration
- Removal and disposal of old equipment
- Permit fees
5. Who pulls the permit and commissions the system?
Permits protect you at resale and insurance time. Commissioning (verifying refrigerant charge, airflow, and controls against spec) is the difference between rated performance and a system that quietly underperforms for 15 years. Both should be in the contract.
6. What are the warranties — separately for equipment and labor?
Typical: 10–12 years on the compressor/parts (manufacturer, often registration-dependent) and 1–3 years on labor (contractor). Ask who handles a warranty claim in year 6 and whether the labor warranty survives if the company changes hands.
7. Can you show me similar local installs?
Two or three references with the same equipment family in your climate is a fair ask for a five-figure project. Verified reviews on a directory profile serve the same purpose — it's exactly why we require documentation from every contractor listed here.

Frequently asked questions
- How many heat pump quotes should I get?
- Three is the practical minimum. Pricing spread between qualified bidders is routinely 20–40%, and comparing quotes surfaces scope differences you'd otherwise miss.
- What's a red flag in a heat pump quote?
- Sizing without a load calculation, refusal to itemize, no permit included, pressure to sign same-day, and quotes that still assume the expired federal 25C tax credit.
- Should I choose the cheapest bid?
- Only if scope, equipment tier, and rebate enrollment genuinely match the other bids. Installation quality determines real-world efficiency more than the equipment brand does.
- Do online reviews matter for HVAC contractors?
- Yes, but verify the fundamentals too: license, insurance, and business registration. That's the baseline we document for every contractor before they appear in this directory.
