12 Questions to Ask Before Signing a Heat Pump Quote

Use these questions to make a cold-climate heat pump quote more concrete. The goal is proof, not sales language.

This checklist does not recommend a provider. It helps homeowners verify sizing, low-temperature performance, backup heat, controls, and paperwork before choosing local HVAC options.

The Questions

  1. Will you provide a Manual J heating and cooling load calculation?
  2. What is my local winter design temperature, and how did you use it?
  3. What is the exact outdoor unit and indoor unit model combination?
  4. Can you show the AHRI certificate or manufacturer submittal for this exact match?
  5. How much heating capacity does the system provide at 17°F, 5°F, and near my design temperature?
  6. What COP or efficiency should I expect at low outdoor temperatures?
  7. What is the estimated balance point for my home?
  8. When does backup heat activate, and what type of backup is included?
  9. If this is dual-fuel, what switch temperature or lockout setting will you use?
  10. How will defrost behavior affect comfort during cold, damp weather?
  11. Do my ducts, returns, static pressure, and airflow support the proposed system?
  12. Who handles permits, commissioning, rebate paperwork, warranty registration, and post-installation settings?

What Good Answers Usually Include

TopicWeak answerStronger answer
Sizing"This size is normal for your square footage.""Here is the Manual J load and how the selected equipment matches it."
Cold capacity"It is a cold-climate model.""Here is the published capacity and COP at 5°F and your design temperature."
Backup heat"It has backup if needed.""Backup activates around this temperature, uses this fuel/source, and is controlled this way."
Rebates"You should qualify.""This exact equipment and paperwork match the current program rules, but you should verify with the program administrator."

Quick Reference

For cold-climate heat pump quotes, ask for Manual J sizing, AHRI/submittal proof, 5°F capacity, balance point, backup heat controls, defrost explanation, duct/airflow checks, and rebate documentation.
