Start with licensing and insurance
Every HVAC contractor doing heating and cooling work in Charlotte should hold a current license from the North Carolina State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors.
Use the Board's free Verify License Search tool to confirm the license is active and matches the business name on your quote before any money changes hands.
Confirm they pull the right permits
A full system changeout or new install requires a mechanical permit through Mecklenburg County Code Enforcement. Ask upfront whether the permit fee is included in the quote.
Reputable contractors are comfortable telling you their permit history and won't discourage you from checking permit status on the county's AccelaMeck portal.
Compare quotes the right way
Get at least three quotes and make sure each one specifies the equipment brand, model, tonnage, and SEER2 rating so you're comparing like for like.
Ask each contractor whether they're quoting R-410A or R-454B equipment, since that affects both upfront cost and long-term parts availability.
Red flags to avoid
Be cautious of any contractor who asks for full payment upfront, refuses to provide a license number, or pressures you to skip the county permit to save time.
Avoid vague quotes that don't list equipment specs or don't include a written warranty on labor and parts.

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.
