Boerne, in Kendall County, grew from 17,865 residents in April 2020 to an estimated 24,047 in July 2025 (Census Bureau), a 34.6% jump. Kendall County’s Community Wildfire Protection Plan points to the area’s “hill country topography” and to a Texas A&M Forest Service finding that “94 percent of Kendall County’s growth is happening in the wildland urban interface,” where new homes meet open land.

Boerne’s median home value is higher than in New Braunfels, Schertz, Cibolo or Converse. Whether the project is zoning a two-story house, a mini split for a casita or workshop, or a higher-efficiency system, ask for a load calculation (Manual J) before you compare equipment prices.
Heat, freezes and fuel choices
The Kendall County plan notes “numerous days with temperatures that exceeded 100 degrees.” At San Antonio International Airport, NOAA’s 1991–2020 normals count about 18 days a year at 100 °F or more, and 2023 had a record 75.
Winter can still bite. During the February 2021 storm the San Antonio airport fell to 9 °F during a 9-day freeze run, and heat pumps work hardest in rare hard freezes like that. Homes with a gas or propane furnace need a fall check-up and working CO alarms.

Boerne HVAC questions
Does an HVAC contractor need to register with the City of Boerne?
Yes. The city says contractors must be registered with the City of Boerne to work inside city limits and to submit the permit applications a project needs. Registration has run through the My Government Online portal since July 14, 2025. Ask any contractor quoting your job to confirm its registration, and call Boerne permitting at (830) 248-1529 with questions.
What if my home is outside Boerne city limits?
City registration and permits apply inside Boerne city limits. In unincorporated Kendall County, ask the contractor which permit or inspection rules cover your address; where no local code is adopted, Texas HVAC rules point to the International Residential Code. The contractor needs a TDLR license either way. This is general information, not legal advice.
Is there a carbon monoxide risk with a gas or propane furnace?
Yes. Carbon monoxide is colorless and odorless, so CPSC recommends a CO alarm on every level of the home outside sleeping areas and a yearly inspection of fuel-burning appliances. If a CO alarm sounds, leave the house and call 911. A contractor can then inspect the furnace before it runs again.
