Confirm state licensing first
Every legitimate HVAC company operating in Raleigh must be licensed through the NC State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors. Search the company name or license number on the Board's public database before requesting a quote.
Check for the license classification too - mechanical contracting licenses have tiers based on project size and scope.
Check insurance and EPA certification
Ask for proof of general liability insurance and workers' comp coverage, especially for larger install jobs. A company that hesitates to provide this is a red flag.
Technicians handling refrigerant must hold EPA Section 608 certification - a legitimate company will have this documented for its crew without pushback.
Look for local reputation and rebate program participation
Companies that have served Raleigh neighborhoods for years, from North Hills to Garner, tend to know local code quirks and inspection timelines better than out-of-market franchises passing through.
Being a Duke Energy Smart $aver participating contractor is a good signal - it means the company has been through the utility's vetting process and can help streamline rebate paperwork for qualifying upgrades.
Compare quotes apples-to-apples
Get written quotes from at least three companies covering the same scope: equipment model, SEER2 rating, labor warranty, and permit handling. A significantly lower bid often means a corner is being cut somewhere.
Ask each company directly whether they'll pull the required City of Raleigh or Wake County mechanical permit - reputable companies always do.

Common questions
How do I know if an HVAC company is licensed in NC?
Search the company or contractor's name on the NC State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors' public license search to confirm active status.
What questions should I ask before hiring an HVAC company?
Ask about license number, insurance coverage, EPA 608 certification for technicians, permit handling, and whether they participate in Duke Energy Smart $aver rebate programs.
Are bigger national HVAC brands better than local Raleigh companies?
Not necessarily - local companies often have deeper familiarity with Raleigh permitting, inspection timelines, and neighborhood-specific ductwork issues. What matters most is licensing, insurance, and reviews, not brand size.

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.
