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