AC Repair & HVAC Contractors in Timberwood Park

Heating and Cooling in Timberwood Park

Timberwood Park is an unincorporated community in north Bexar County, about 22 miles north of downtown San Antonio on the southern edge of the Hill Country. It is roughly bounded by Canyon Golf Road, Borgfeld Road and Blanco Road. The community grew from 13,447 residents in 2010 to 35,217 in 2020, and its original subdivision has 3,263 platted lots.

Larger, multi-level homes often have two systems or a zoned system, with long duct runs through attics that face the afternoon sun. An upstairs that will not cool is more often caused by duct design, return air or attic heat than by the equipment alone.

Heat, Attics and Sizing in Timberwood Park

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 Timberwood Park

• Split AC with a gas furnace. An outdoor condenser plus an indoor coil on top of a gas furnace. Some homes here have gas service, and others are all-electric with heat pumps. On the edge of the Hill Country, freezing nights do happen, so check how the backup heat strips are controlled.
• 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.

Permits Outside City Limits

Because Timberwood Park is outside any city, San Antonio’s permit office does not cover it. Bexar County’s building permit program is run by the Fire Marshal’s Office (210-335-0300), and the county says it applies to structures that are not single-family dwellings. As a result, a typical home AC replacement here may not go through a county mechanical inspection. That makes your own paperwork more important:

• Get a written scope that names the equipment, the AHRI certificate number, the line set and the drain work.
• Ask for the Manual J load calculation in writing.
• Keep the TDLR license number on the invoice.
• Check with your HOA about where outdoor equipment can be placed and how it must be screened.

If you are not sure whether your address is inside a city’s limits, call the county before work starts. CPS Energy asks for a permit number only on jobs inside San Antonio city limits.

Utility Rebates for Timberwood Park Homes

CPS Energy. If your electric bill comes from CPS Energy, its 2026 residential HVAC rebate covers central AC, central heat pumps and ductless mini-splits installed from February 1, 2026 through January 31, 2027. According to CPS Energy’s published table, the rebate pays $90 to $275 per cooling ton for replace-on-burnout jobs and $115 to $310 per cooling ton for early replacement of a working system, rising with the SEER2 tier. The main conditions are:

• It must be a one-for-one replacement in an existing home, installed by an HVAC contractor licensed in Texas.
• Your contractor’s invoice must list the model and serial number of each new indoor and outdoor unit, and it must match an AHRI certificate.
• To claim the early-replacement rate, the old central system must still work and be under 25 years old (under 20 for heat pumps), and you need photos plus its model and serial numbers.
• Apply within 30 days of completion. CPS Energy asks for a permit number on jobs inside San Antonio city limits.

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.
