Heating and cooling in Carrollton
Carrollton's Mechanical Work page says a permit is needed when any part of the indoor or outdoor unit is repaired or replaced, and that adding refrigerant needs none. Single-trade permits, mechanical included, are $4 per $1,000 of value with a $75 minimum. No effective date appears on the Building Inspection Fees page. A non-refundable application processing fee of $125 is on that page too, and it says that for permits under $125, the permit fee is the application fee.
The page doesn't explain how that line sits with the $75 minimum, so ask Building Inspection which one your permit falls under. The same fee page lists trade contractor registration for mechanical, plumbing, electrical and general contractors at $0. On HVAC work by a contractor, the Mechanical Work page says the contractor must hold a TDLR air conditioning and refrigeration license and be registered with the city. Carrollton's Codes & Ordinances table lists the 2024 IBC, IRC, IECC, IPC, IFGC and IMC with the 2023 NEC, each effective 09/01/25 (Ordinances 4265 and 4290), with combined local amendments.
The previous cycle is shown as the 2021 I-Codes and 2020 NEC. Building Inspection is at Carrollton City Hall, 1945 East Jackson Road, phone 972-466-3225. It keeps 7:30 a.m. to 5:30 p.m. hours from Monday to Thursday and closes at 11:30 a.m. on Friday. The CityServe portal takes permit applications and inspection requests. Carrollton housing was built, at the median, in 1988 (ACS, 2020 to 2024). A repair to part of a unit needs a permit; a refrigerant top-up alone doesn't.

Permits for heating and cooling work in Carrollton
Texas cities issue the permit for replacing a furnace, air conditioner or heat pump, and each city sets its own fee; the ones cited on our Texas page all require one. TDLR licenses the air conditioning and refrigeration contractor, so ask for that license number as well as what your city's permit office needs.
