AfterHVAC Company in Schertz, TX
Most HVAC calls in Schertz involve builder-grade systems in 2003-2015 tract homes that were undersized for open floor plans and high ceilings from day one. We’re Coldharbour Heating & Air, and we dispatch crews to Schertz from our San Antonio scheduling office every day of the year. A live person answers our phones 24/7 at (817) 402-2972, and we issue a written price before any work begins backed by our 365-Day Done Right Promise.
Why Schertz Homes Are Different
Schertz sits in the San Antonio metro heat corridor where daily highs exceed 100°F for weeks at a stretch, placing extreme runtime stress on air conditioners from May through October. The housing stock here is dominated by slab-foundation, single-story and two-story tract homes built primarily by DR Horton, KB Home, and Pulte from the early 2000s onward. These builder-grade systems were frequently undersized for the actual square footage and ceiling heights, a chronic mismatch that shows up as rooms that never cool properly during peak summer.
The February 2021 Winter Storm Uri also left its mark. Many Schertz heating systems had rarely been tested below 30°F, and the freeze cracked heat exchangers and refrigerant lines that are still failing today. Add the Schertz-Seguin water supply’s notable hardness and the insufficient slope on builder-installed condensate drain lines, and you get chronic clogs and float-switch shutdowns that spike every July and August. The constant military PCS turnover from neighboring JBSA-Randolph means we regularly find years of deferred maintenance compressed into a single service call on an otherwise newer home.
Our Main Schertz Services
Schertz homeowners call us most often for cooling repairs in peak summer and heating repairs after cold snaps, with system replacement growing as those first-generation builder units age out. Each service has its own dedicated Schertz page with full details.
AC Repair in Schertz
AC repair in Schertz means tracking down why an undersized builder-grade unit can’t keep up with 100°F days, or clearing a hardened condensate clog before it triggers a float-switch shutdown. Our trucks carry capacitors, contactors, and refrigerant to handle the most common failures we see in Kensington Ranch, Crossvine, and Fairhaven homes. Every repair comes with a written price upfront and our 365-Day Done Right Promise. AC Repair in Schertz

You’ll get the written price before we start and the full year-long guarantee. Furnace Repair in Schertz

What Schertz 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."
