Code adoption changes. We confirm the currently adopted cycle with the authority having jurisdiction on every permit we pull.
Verify our license
Art Electric & HVAC holds both a Texas mechanical contractor license (TACLA TACLA000000C) and a Texas electrical contractor license (TECL TECL00000). Verify either one yourself:
TDLR license searchPermit questions homeowners ask
Do I need a permit to replace my AC in Rockwall?
Yes. Every city in Rockwall County requires a mechanical permit for an equipment change-out, including a like-for-like replacement. We pull the permit under our TACLA license and meet the inspector — it is included in your quoted price, never billed separately.
Do I need a permit for an EV charger?
Yes. A Level 2 charger is a new dedicated 240V circuit and requires an electrical permit and inspection in every jurisdiction we serve. If the install also needs a panel upgrade, that is covered on the same permit.
Who pulls the permit — me or the contractor?
The licensed contractor. In Texas, a homeowner can pull a permit for their own primary residence, but doing so makes you responsible for code compliance and can void manufacturer warranties and affect your homeowner's insurance after a claim.
How can I verify a Texas HVAC or electrical license?
Search the contractor's name or license number on the Texas Department of Licensing and Regulation (TDLR) license search. HVAC contractors hold a TACLA or TACLB number; electrical contractors hold a TECL number. Ask for both — many companies hold only one.
What code cycle does Rockwall enforce?
Rockwall County jurisdictions currently enforce the 2020 National Electrical Code and the 2021 International Mechanical and Energy Conservation Codes, with local amendments. Code cycles change; we confirm the adopted cycle at permit time on every job.
How long does inspection take after the work is done?
Most Rockwall-area jurisdictions inspect within one to two business days of the request. We schedule the inspection, meet the inspector on site, and send you the closed permit for your records.
What happens if previous work was done without a permit?
Unpermitted mechanical or electrical work commonly surfaces during a home sale inspection. We can evaluate the existing work, correct anything that fails current code, and pull a retroactive permit where the jurisdiction allows it.
Does a permit affect my property taxes?
A mechanical or electrical permit for equipment replacement does not change your appraised value in Rockwall County. Permits for square-footage additions can.
