How to Hire a Heat Pump Contractor
The right contractor makes the difference between a system that performs for 20 years and one that underperforms from day one. This guide covers the credentials to verify, the questions to ask, the red flags to watch for, and how to compare quotes so you can hire with confidence.
Credentials to Look For (US)
HVAC Contractor License
State-issued license verifying the contractor is qualified to install HVAC systems. Requirements vary by state.
Master Electrician
Required for panel upgrades or electrical work associated with heat pump installation.
EPA 608 Certification
Federally required for anyone handling refrigerants. No exceptions.
NATE Certification
North American Technician Excellence — voluntary but demonstrates verified competency in HVAC installation and service.
Liability Insurance + Bond
Protects you if something goes wrong during installation. Ask for a certificate of insurance.
Credentials to Look For (Canada)
Red Seal (Refrigeration Mechanic 313A)
National certification for refrigeration and air conditioning mechanics. The gold standard in Canada.
FSR (Field Safety Representative)
Required in BC for contractors working with gas appliances. Ensures compliance with gas safety regulations.
TSBC Licence (BC)
Technical Safety BC licence required for refrigeration and gas work in British Columbia.
Class B Gas Fitter
Provincial certification for installing and servicing gas-fired appliances, including hybrid/dual-fuel systems.
WorkSafeBC Coverage
Confirms the contractor carries workers' compensation coverage. Protects you from liability if a worker is injured on your property.
Questions to Ask Before Signing
How many heat pump installations have you completed this year?
Experience matters. A contractor who installs heat pumps regularly will be faster, more accurate, and better at troubleshooting.
Are you licensed for both refrigeration and electrical work?
Heat pump installs often require both. If they subcontract electrical, ask who the electrician is and verify their license.
Do you perform a Manual J load calculation?
Proper sizing prevents oversized or undersized systems. A Manual J (or CEC equivalent in Canada) is the industry standard.
What warranty do you offer on labor?
Equipment warranties come from the manufacturer. Labor warranties come from the contractor — and they vary widely (1 to 10 years).
Will you handle the permit application?
Most jurisdictions require a mechanical or building permit. A good contractor handles this as part of the job.
Can you provide 3 recent references?
References from the last 6 months are most relevant. Ask about communication, cleanup, and whether the system performs as quoted.
What happens if the system doesn't perform as quoted?
A confident contractor will have a clear answer — whether it's a callback policy, performance guarantee, or adjustment commitment.
Do you offer a written maintenance plan?
Annual maintenance extends system life and maintains efficiency. Some contractors include the first year; others offer ongoing plans.
Red Flags in a Quote
No line-item breakdown
A lump-sum quote hides what you're paying for. You should see separate costs for equipment, labor, electrical, permits, and materials.
Sizing based on "rule of thumb"
Statements like "1 ton per 500 sq ft" ignore insulation, windows, climate, and duct losses. Proper sizing requires a load calculation.
No mention of permits or inspections
Skipping permits means no third-party verification that the work meets code. It can also void your warranty and cause problems when selling.
Pressure to sign today or lose a discount
Legitimate contractors don't use high-pressure sales tactics. If a deal disappears overnight, it wasn't a real deal.
Equipment brand not specified
You should know exactly what's being installed — manufacturer, model number, and capacity. Vague descriptions like "high-efficiency unit" are a red flag.
No warranty terms in writing
Verbal promises mean nothing. Equipment and labor warranty terms, durations, and exclusions should be in the contract.
What a Fair Contract Should Include
- ✓Equipment make, model, and size (BTU/tons)
- ✓Total price with line items (equipment, labor, electrical, permits)
- ✓Start and completion dates
- ✓Warranty terms (equipment + labor)
- ✓Payment schedule (never 100% upfront)
- ✓Permit responsibility
- ✓Change order process
How to Compare 3 Quotes
Get at least 3 quotes from licensed contractors. The cheapest quote is rarely the best — look for value, completeness, and professionalism. Ask each contractor to explain their quote relative to what others have proposed.
Equipment brand/model
Are all three quoting the same tier of equipment? A low quote with a budget brand is not the same value as a higher quote with a premium unit.
Total installed price
Compare apples to apples — the total should include equipment, labor, electrical, permits, and any ductwork modifications.
Warranty length
A 1-year labor warranty vs. a 5-year labor warranty represents real financial risk to you if something goes wrong.
Included work
Does the quote include electrical upgrades, permits, ductwork sealing, thermostat, and commissioning? Exclusions add up fast.
Timeline
A contractor who can start in 2 weeks vs. 3 months may reflect demand — but also capacity and crew size.
