Heating and cooling in Round Rock

The codes in force on Round Rock's building inspection pages are the 2024 IMC (International Mechanical Code), the 2024 IECC, the 2024 IRC, the 2024 IPC and the 2023 NEC, along with the Texas Accessibility Standards and the city's Code of Ordinances. Planning and Development Services is at 301 W. Bagdad Avenue, Suite 210, Round Rock, TX 78664, phone 512-218-5428. Inspection Services is at Suite 100, 512-218-5550, and inspections run from 8:00 a.m. until 3:00 p.m. on weekdays Permit applications are filed in the online Permit Portal.

Round Rock's fee pages print no mechanical row. Its Residential Single Family Remodel & Additions page prints "Permit Fee: $500.00," and the Planning & Development Fees Summary, headed "Updated August 2023," covers zoning, platting, site development and building permits, with a $50 structural moving permit and a $35 tenant change permit. The remodel page carries no date and doesn't say whether a unit replacement counts as a remodel, so that's the question for Suite 210.

Census figures (2020 to 2024) give Round Rock a 2002 median year built, with 9.8% of units put up in 1950 to 1979. The median value of an owner-occupied home is $418,600. Suite 210, at 512-218-5428, is the office that answers whether a replacement is priced as a remodel.

What heating and cooling work costs near Round Rock

Nobody's given us a quote for work in Round Rock yet, so this page can't show a city price. The Texas page lists the estimates with what technicians earn (the Texas mean in May 2025 BLS wage data is $28.43 an hour, which is their pay, not your price) and some city permit fees. How we estimate costs.

Permits for heating and cooling work in Round Rock

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.
