12 Questions to Ask Before or During Heat Pump Quote Visits
Use these questions before requesting quotes or while contractors are evaluating the home. Their job is to make the eventual proposals more concrete.
This is not the Bid Decoder and it is not the final Installer Checklist. It prepares the questions; the later tools inspect the written quote and the final signing scope.
The three quote stages
1. Before and during visitsUse this page to ask for the right calculations, specifications, and explanations.
2. After quotes arriveUse the Bid Decoder to check what the written proposals contain or omit.
3. Before signingUse the Installer Checklist for qualifications, responsibilities, scope, and handoff.
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 source, and is controlled this way.” |
| Rebates | “You should qualify.” | “This exact equipment appears to match the program, but eligibility must be verified with the administrator.” |
What to Take Into the Quote Stage
Ask each contractor for a written answer or document covering Manual J, design temperature, exact matched equipment, low-temperature capacity, balance point, backup heat, defrost, duct or airflow findings, commissioning, and paperwork responsibilities.
