AC Repair & HVAC Contractors in Cibolo

Heating and Cooling in Cibolo, TX

Cibolo is a fast-growing city in Guadalupe and Bexar counties. It incorporated in 1965 and grew from 15,349 residents in 2010 to 32,276 in 2020, so most homes are recent subdivision builds. Those houses usually have the air handler and ducts in the attic, and many builder-installed systems from that boom are now reaching repair-or-replace age.

The city says GVEC is Cibolo’s primary electric provider, which affects which rebate you can use (see below). The contractor list above is a directory, not an endorsement.

Heat, Attics and Sizing in Cibolo

Cooling is the main job for any system here. At the San Antonio airport weather station, the 1991–2020 normals average about 122 days a year at 90°F or hotter, with a normal August high of 96°F. The same record shows roughly 3,148 cooling degree days against 1,438 heating degree days, so an air conditioner works more than twice as hard over a year as a furnace or heat pump does in heating mode. Winter still matters: the normals also average about 14 nights a year at or below freezing.

The DOE places Bexar and Guadalupe counties in climate zone 2A (hot-humid). For an attic in zone 2, ENERGY STAR recommends insulating to R49 when there is none, or adding R38 on top of 3–4 inches of existing insulation. That matters because many homes in this area run their ductwork and air handler in the attic, which can get far hotter than the outdoor air on a summer afternoon. Leaky or poorly insulated ducts there pull hot attic air into the system, so before you buy a larger unit, ask the contractor to check the duct connections, the insulation depth and the return air path.

System Types You Will See in Cibolo

• Split AC with a gas furnace. An outdoor condenser plus an indoor coil on top of a gas furnace. If your Cibolo home has gas service, this pairing is common. If it does not, a heat pump is the usual all-electric choice.
• Heat pump. One outdoor unit that cools in summer and reverses to heat in winter, usually with electric backup heat strips for freezing nights. It suits all-electric homes, and it is the type that both CPS Energy and GVEC rebate programs cover.
• Ductless mini-split. Wall or ceiling heads fed by an outdoor unit, often used for garage conversions, additions and rooms the main ducts never reached. CPS Energy rebates cover mini-splits; GVEC’s rebate does not.

Efficiency floor. CPS Energy’s rebate minimum for a central or mini-split AC under 45,000 BTUh (under about 3.75 tons) is 14.3 SEER2, or 13.8 SEER2 at 45,000 BTUh and above. Ask for the AHRI certificate number for the exact outdoor unit, coil and furnace or air handler combination on your quote, because that certificate is what the utilities use to check the rating.

Refrigerant. New systems now commonly use lower-GWP refrigerants such as R-454B or R-32 in place of R-410A. In a May 26, 2026 rule, EPA removed the federal installation deadline for R-410A split systems as long as every component was made or imported before January 1, 2025. If a quote lists an R-410A system, ask for the manufacture dates, and see our refrigerant guide for what each type means for future repairs.

Cibolo HVAC Permits

• Same-day replacement permits. The City of Cibolo says permits for HVAC replacement equipment can be issued the same day without plan review.
• Registered contractors. Contractors must be registered with the city.
• Homeowners. The city says a homeowner cannot obtain an HVAC permit without a Texas mechanical license, so the licensed contractor pulls it.
• Online. Applications are submitted through MGO Connect. Questions go to the city at 210-658-9900.

Utility Rebates for Cibolo Homes

GVEC. GVEC members can get a $650-per-unit rebate on a new all-electric heat pump rated 17 SEER2 or higher, in a new or existing home. GVEC’s requirements include a licensed contractor; a new, matched AHRI-certified system with both the condensing unit and the air handler or coil replaced; supply and return ducts sealed or repaired; auxiliary heat controlled by an outdoor temperature sensor set at the system’s balance point; and a Manual J (8th edition) load calculation at 75°F indoor and 97°F outdoor design conditions. It also asks for a signed invoice (estimates are not accepted) and the AHRI certificate. Ductless mini-splits do not qualify. Questions go to GVEC at 800-223-4832.

If your bill comes from CPS Energy instead, its 2026 rebate pays $90 to $310 per cooling ton on qualifying central AC, heat pump and mini-split replacements installed by a Texas-licensed contractor, and you must apply within 30 days of completion.

Check the License Before Anyone Opens the Unit

Under Texas law, anyone who installs, repairs or maintains air conditioning, refrigeration or heating systems must hold a TDLR license, and every ACR company must employ a licensed ACR contractor at each permanent location. Search the company or contractor name in the TDLR license search and compare the number with the one printed on the quote and the truck. The listings above show the TDLR number where one has been provided. Also ask for a certificate of insurance and a written warranty that covers both parts and labor.
