Heating and cooling in Plano
Building permits in Plano go through Building Inspections at 1520 K Ave, Suite 140, Plano, TX 75074. You can call 972-941-7140, send a fax to 972-941-7187 or write to buildingpermits@plano.gov. Ask that office what a furnace or condensing-unit swap costs before the work is booked, because Plano's permit pages don't list what a mechanical permit costs. Texas requires anyone who installs, repairs or maintains air conditioning or heating systems to hold a TDLR license, and TDLR's license search has a list for Air Conditioning Contractors and one for A/C Technicians.
Plano's housing stock dates to a median year built of 1993 (ACS, 2020 to 2024), with 17.9% of units built in 1950 through 1979 and a $465,900 median value for owner-occupied homes. Check the license number a company gives you on TDLR's license search.

Permits for heating and cooling work in Plano
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.
