Check registration before anything else
Every legitimate HVAC company in Spokane must be registered as a construction contractor with the Washington State Department of Labor & Industries, with an active bond and liability insurance. Ask for their UBI number and verify it on the L&I site yourself rather than taking their word for it.
A company that's unregistered or has a lapsed bond isn't just a red flag, it also means you have far less recourse if the job goes badly.
Ask about permit history
A company that regularly does mechanical work in Spokane should be comfortable talking through the City of Spokane Development Services Center permit process without hesitation. If a company suggests you don't need a permit for a full system replacement, that's a warning sign.
You can also ask for a couple of recent local addresses or job references where they pulled permits, especially if you're getting a larger install like a ductless multi-zone system.
Look for Spokane-specific experience
Ask how many ductless mini-split installs they've done in older neighborhoods like Browne's Addition or Peaceful Valley, since retrofit work in homes without existing ducts requires different skills than straightforward duct-based replacements.
Ask whether they're an Avista trade ally or familiar with current Avista rebate paperwork, since a company that regularly helps customers claim utility rebates usually has its administrative and technical processes dialed in.
Red flags that should end the conversation
Be wary of companies that pressure same-day signing, only accept large upfront cash payments, or can't provide a written, itemized quote. Also watch for companies quoting prices dramatically below the ranges typical for this metro, since that often means corners get cut on materials or licensing.
A trustworthy Spokane HVAC company will happily let you verify their L&I registration, explain the permit process, and give you time to compare quotes.
Typical cost ranges
| Diagnostic/service call | $95 - $175 |
| Furnace replacement | $3,800 - $8,500 |
| Central AC replacement | $4,500 - $9,500 |
| Ductless mini-split (multi-zone) | $9,000 - $16,000 |
Ranges are general estimates gathered from homeowner-reported quotes, not an offer or a quote for your project.
Common questions
How do I verify an HVAC company's license in Spokane?
Look up their registration, bond, and insurance status through the Washington State Department of Labor & Industries contractor lookup using their UBI number.
What permit office handles HVAC permits in Spokane?
The City of Spokane's Development Services Center issues mechanical permits for furnace, AC, and ductless mini-split installations.
Should I be worried about a very low quote?
Yes, unusually low quotes compared to typical Spokane metro pricing often mean unlicensed labor, skipped permits, or lower-grade equipment.
Are Avista rebates a good way to judge a company?
A company familiar with Avista's rebate process for high-efficiency equipment often signals more administrative and technical experience, though it's not the only factor to check.

The Henry Standard
Every HVAC contractor in our network agrees to three things.
Show up
Call back. Keep appointments. And if something changes, communicate it.
Quote honestly
Equipment, scope, permit, and price in writing — so you know what you're agreeing to.
Finish the work
See the job through, pull the permit, and pass inspection before calling it finished.
Nothing revolutionary. Just the way we believe doing business should still be done.
