HVAC Company in Timberwood Park, TX
Most HVAC calls we get from Timberwood Park aren’t like the ones from downtown San Antonio. The homes here sit on acre-plus lots in dense Ashe juniper country, running propane-fired furnaces and heat pumps through limestone-karst terrain that swings 30 degrees overnight. We’re Coldharbour Heating & Air, and our technicians train specifically for these conditions: cedar-pollen-clogged condensers in January, propane gas-valve tuning, and load calculations that account for 1,400-foot elevation and 90-plus-day cooling seasons. If your system’s acting up, call us at (817) 402-2972. A live person answers, day or night.
Why Timberwood Park Homes Are Different
Timberwood Park sits on the southern edge of the Edwards Plateau, roughly 1,400 to 1,500 feet up. That elevation means summer nights run 3 to 5 degrees cooler than San Antonio proper, which sounds pleasant until you’re sizing a replacement system. An oversized unit short-cycles itself to death in those conditions. We’ve seen it repeatedly in the ranch-style homes built here from the mid-1980s through the early 2000s.
The housing stock matters too. These are custom and semi-custom single-story homes on one-acre-plus lots, with duct runs stretching across wide footprints and attics that were never sealed to modern standards. Systems hit 20 to 35 years old regularly. The mature cedar-oak canopy that makes Timberwood Park beautiful also forces non-standard condenser placement to dodge excessive shade and debris.
Then there’s the propane factor. Because this is unincorporated Bexar County with no municipal natural-gas lines, nearly every furnace and dual-fuel heat pump here runs on propane. Our technicians set gas-valve pressure to propane specs, not the natural-gas standard you’d expect fifteen minutes south. Get that wrong and the homeowner gets incomplete combustion, soot, or a safety shutdown.
And the pollen. December through February, Ashe juniper releases so much pollen that outdoor condenser coils can pack solid enough to trip high-pressure lockouts. We see this call pattern every winter. Dispatchers unfamiliar with Timberwood Park sometimes misdiagnose it as a refrigerant issue. Our local techs know to check airflow first.
Our Main Timberwood Park Services

AC Repair in Timberwood Park
AC repair in Timberwood Park means dealing with systems stressed by limestone-karst temperature swings and cedar debris.

Our trucks stock capacitors, contactors, and refrigerant for same-day resolution on most calls. Every repair comes with our written 365-Day Done Right Promise. AC Repair in Timberwood Park

Furnace Repair in Timberwood Park
Furnace repair here is almost always propane-fired equipment, whether it’s a standing-pilot conversion, a gas-valve pressure adjustment, or an igniter replacement in a 20-year-old Goodman or Rheem. We also service the heat-pump reversing valves that get more wear in Timberwood Park’s dramatic spring and fall swings than in flat terrain. The written price hits your hand before we start.

AC Installation in Timberwood Park
AC installation in Timberwood Park requires a Manual J load calculation that accounts for elevation, acre-lot wind exposure, and those cooler nights. We size for the full summer heat, not the average, because 100-degree days still happen. Duct sealing and zoning often matter more here than in compact suburban homes. We handle rebate paperwork and schedule a firm install date after load calculation and equipment selection. AC Installation in Timberwood Park

What Timberwood Park Customers Say
"Furnace was short cycling all winter. They diagnosed a bad sensor instead of condemning the whole unit like I feared. Cheap fix, honest call."
- Russ Tiedemann"Thermostat and a weak blower. Fixed both in one visit, explained the guarantee, and didn't leave a mess. I've already recommended them to my neighbor."
- Natalie Esposito"Honest to a fault. Two companies told me I needed a whole new unit. Coldharbour said mine had years left and just needed a cleaning and a part. Saved me thousands."
- Marcus Reilly
