Hiring a contractor for heat pump installation is a high-trust decision and the consumer protections are weak — most state license boards are reactive, most carriers won't get involved unless something physically breaks. That puts the burden of vetting squarely on you. Here's how we'd do it if we were the homeowner.

Most states regulate this work at the contractor level. Ask any contractor you're considering for the license number on the call. Cross-check it against the state's public lookup. Confirm it's active, in the right classification for this trade, and has no open complaints.
If a contractor hedges or refuses to share the number, that's a strong signal to keep looking.
Get the scope in writing — including the actual model number
Vague proposals are how change orders happen. Insist on a written scope that includes:
- Manual J load calculation with the proposal (not a rule-of-thumb size)
- AHRI certified matched system number on the contract
- HSPF2 / SEER2 ratings, not the older HSPF / SEER
- Cold-climate rating if you live anywhere with sustained sub-20°F temps
- Refrigerant lineset length and warranty terms in writing
6 questions to ask before you sign
Anyone who's done heat pump installation for years should answer all of these without hesitation. If they hedge, you're talking to the wrong company:
- Will this work below zero?
- Do I need backup heat?
- Will my electric bill go up or down?
- Can I keep my existing ductwork?
- How loud is the outdoor unit?
- What is the warranty if a compressor fails in year 8?

Red flags that should end the conversation
Any of these are reason to politely walk away:
- "I don't pull permits — saves you money."
- Aggressive same-day discount pressure ("only if you sign tonight")
- Refusal to provide a written scope before deposit
- No physical local address — only a cell number and a Google Voice line
- "Free roof / free upgrade" pitches that involve filing your insurance claim for them
- Refusing to name the equipment manufacturer or model on the proposal
