Charlotte rows from ConsumerAffairs; the national row is labeled.

Do this now: no heat or no cooling in Charlotte

1. Gas smell or a carbon monoxide alarm: get everyone out and call 911 or Piedmont Natural Gas from outside (CPSC).
2. Check the thermostat mode and setting, and replace a clogged filter.
3. Check the breakers for the outdoor unit and the furnace or air handler; leave off any that trip again right away.
4. No cooling with someone elderly or ill at home: move to the coolest room or a cooler place while you wait.
5. Note any error lights, noises or ice on the lines.

Is it an emergency? Charlotte's heat and freezing nights

Charlotte Douglas averages 49.2 days a year at or above 90 F, 1.0 day at or above 100 F and 58.3 nights at or below 32 F in NOAA's 1991 to 2020 normals. No cooling in a heat wave or no heat on a freezing night is urgent, especially with infants, older adults or anyone ill in the house. A gas smell or a CO alarm is a 911 call first. A system that still runs but sounds wrong can wait for a weekday visit, when diagnostic fees are lower.

Permits and licenses for HVAC work in Charlotte

North Carolina requires a heating contractor license, class H1, H2 or H3, which you can verify on the State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors' public search. State law G.S. 160D-1110(c)(3) takes heating and air conditioning replacements out of the no-permit exemption for small jobs, so a new furnace, heat pump or AC needs a permit. In Charlotte that permit comes from Mecklenburg County Code Enforcement, 980-314-CODE (2633), and the contractor pulls it.

ConsumerAffairs warns that ads for a $29 service call are often a bait and switch. The real diagnostic fee in Charlotte runs $75 to $145, per the same report, so ask what is included before anyone is sent.
