Contractor Quote Checklist
Heat Pump Installation Quote Checklist Before Signing
Short answer: a heat pump installation quote should explain the load calculation, equipment match, indoor and outdoor unit pairing, duct or distribution assumptions, electrical work, thermostat controls, cold-weather performance, permits, rebates, warranty terms, and exclusions before you sign.
This guide is for a homeowner replacing an aging air conditioner, furnace, or mixed HVAC setup with a heat pump. The quote may look simple: equipment, labor, thermostat, and a total. The real decision is not simple. A heat pump changes how heating and cooling are delivered, how the system performs in cold weather, and what supporting work may be needed.
Do not compare heat pump bids by equipment name alone. Compare the assumptions behind the bid. A lower quote can become expensive if it skips sizing, duct review, electrical changes, permit work, condensate details, or backup heat questions.
Start With The Home Load, Not The Old Equipment
Ask whether the contractor performed a room-by-room or whole-home load calculation. The old system size is not proof that the new heat pump should be the same size. Insulation, windows, air leakage, orientation, additions, finished basements, and comfort complaints can all change the design.
DOE heat pump guidance explains that heat pumps move heat rather than generate it directly, which is why correct sizing and installation matter. Oversizing can hurt comfort and humidity control. Undersizing can leave the home leaning on backup heat too often.
- What sizing method was used?
- Were insulation, windows, and room-by-room comfort issues considered?
- Is the quote replacing both heating and cooling, or cooling only?
- Does the system need backup heat, and when would it run?
Confirm The Outdoor And Indoor Equipment Match
A heat pump is not just an outdoor box. The quote should identify the outdoor unit, indoor air handler or coil, blower assumptions, refrigerant lines, filter cabinet, drain pan, condensate route, thermostat, and any backup heat kit.
Ask for model numbers and the performance match. If a contractor proposes keeping an existing indoor coil or air handler, ask whether that combination is approved, efficient, and covered by warranty. A mismatched system can create performance and warranty problems.
Ask How Cold Weather Performance Is Handled
In colder climates, the quote should explain how the system performs at lower outdoor temperatures. Ask for heating capacity at design temperature, balance point assumptions, defrost behavior, backup heat source, and control settings.
If the home will keep a furnace, ask whether the job is a dual-fuel setup and how the thermostat decides when to switch. If electric resistance backup is included, ask what electrical work and operating conditions are assumed.
Ducts, Returns, And Airflow Belong In The Quote
Heat pump comfort depends on airflow. The quote should say whether existing ducts, returns, registers, static pressure, filter size, and leakage were reviewed. A system can be correctly sized on paper but still perform poorly if the ductwork cannot move enough air.
Ask whether duct sealing, return enlargement, supply changes, balancing, or insulation are included. If they are excluded, ask what symptoms would make that work necessary later.
Electrical Scope Should Be Plain English
Heat pump installation may require a disconnect, breaker change, new circuit, service capacity review, control wiring, surge protection, or backup heat wiring. The quote should state what is included and who handles any panel work.
Do not assume “electrical included” covers everything. Ask whether permit, inspection, trenching, conduit, wall patching, thermostat cable, and panel labeling are included or separate.
Permits, Rebates, And Utility Paperwork Can Affect Timing
Ask which permits are required and whether the contractor files them. Some rebate programs require specific equipment ratings, contractor documentation, pre-approval, invoices, photos, or commissioning forms.
A rebate should not be treated like guaranteed cash unless the quote states who is responsible for eligibility, forms, deadlines, and supporting documents.
Heat Pump Quote Review Table
| Quote area | What to confirm | Why it matters |
|---|---|---|
| Sizing | Load calculation method and room assumptions | Prevents comfort problems from guesswork. |
| Equipment match | Outdoor unit, indoor coil or air handler, backup heat, thermostat | Protects performance and warranty coverage. |
| Airflow | Duct, return, filter, and static pressure review | Heat pumps need steady airflow to work well. |
| Electrical | Breaker, disconnect, wiring, panel capacity, inspection | A missing electrical scope can trigger change orders. |
| Paperwork | Permits, rebates, model numbers, commissioning checklist | Documentation affects approval, incentives, and resale records. |
Questions To Ask Before Approval
- What load calculation supports the proposed system size?
- What indoor and outdoor model numbers are included?
- Will the system heat the home at the local design temperature?
- What backup heat is included, and when will it run?
- Were ducts and return air checked?
- What electrical work is included or excluded?
- Who pulls permits and schedules inspection?
- What rebate paperwork is the contractor responsible for?
Red Flags In A Heat Pump Quote
Be careful with quotes that size from the old unit only, do not name model numbers, ignore ductwork, promise rebates without paperwork, include vague electrical language, or treat backup heat as an afterthought.
Also be careful when a contractor pushes the biggest unit as the safest choice. Capacity is not the same as comfort. The better quote explains the design.

FAQ
Should a heat pump quote include a load calculation?
Yes. Ask how the contractor sized the system and whether the calculation reflects the current home, not just the old equipment label.
Is backup heat always required?
Not always in the same way. The quote should explain local climate assumptions, low-temperature performance, and any backup heat source or dual-fuel control plan.
Can existing ducts be reused?
Sometimes, but the quote should say whether airflow, return size, duct leakage, and filter setup were reviewed. Reusing poor ducts can make a good heat pump feel bad.
Who handles permits and rebates?
The quote should name the responsible party for permits, inspections, rebate forms, equipment documentation, and submission deadlines.
What is the biggest approval risk?
The biggest risk is approving equipment without the supporting design details: load, airflow, electrical scope, backup heat, and warranty terms.
