AfterHVAC Company in Alamo Heights, TX
Most HVAC companies serving Alamo Heights treat it like another San Antonio neighborhood, but it’s an independent city with its own building department, its own permit process, and a housing stock that predates modern forced-air systems by decades. We’re Coldharbour Heating & Air, and our technicians are trained on the retrofit realities of 1920s limestone estates and 1950s brick ranches, not just standard suburban installs. If your system quits in July heat or a February cold snap, call us at (817) 402-2972. A live person answers, and we’ll give you a firm arrival window.
Why Alamo Heights Homes Are Different
Alamo Heights sits entirely inside San Antonio’s city limits but operates its own building department, which means every permit for equipment replacement or major duct modification gets routed through Alamo Heights, not COSA. Outside contractors regularly discover this mid-project, and the resulting stops and restarts add days homeowners didn’t budget for.
The housing itself is the bigger variable. Most homes here were built between 1925 and 1960 as custom masonry residences, regional limestone block and brick that complicate every aspect of HVAC work. Original gravity-fed or undersized forced-air ductwork, irregular attic framing, and wall assemblies nothing like modern tract construction mean simple equipment swaps are rare. We’ve worked on estates where additions across three decades layered incompatible ductwork, creating chronic airflow imbalances no thermostat can fix.
Then there’s the tree canopy. Alamo Heights enforces aggressive heritage live oak protections, and those massive oaks often dictate or block legal condenser placement entirely. They also shed pollen and tannin-laden debris that clogs outdoor coil fins faster than in open-lot neighborhoods, making annual coil cleaning almost mandatory to keep rated efficiency.
The climate adds its own pressure. San Antonio’s position at the Edwards Plateau edge means sustained triple-digit heat from May through September, with periodic Gulf humidity surges that push latent loads high. Oversizing equipment is a constant temptation here, but it leads to short-cycling and mold in older, less-sealed homes. Winter cold snaps, like the 2021 freeze, expose attic-run ductwork in poorly insulated 1940s homes to near-freezing temperatures.
Our Main Alamo Heights Services
Homeowners in Alamo Heights call us most often for cooling repair, heating repair, and full system replacement. Each job type carries its own local considerations, which is why we’ve built dedicated pages for the work we do here.
AC Repair in Alamo Heights
AC repair in Alamo Heights runs from simple capacitor and contactor swaps to hunting refrigerant leaks in aging linesets buried in limestone foundations. The pollen load from live oaks means we frequently find condenser coils so clogged that pressures read like a mechanical failure until we clean them. Our trucks stock capacitors, contactors, and refrigerant for same-day resolution on most calls. AC Repair in Alamo Heights
Furnace Repair in Alamo Heights
Furnace repair here often means working on original or long-ago-replaced units in cramped utility closets or converted basement spaces with access issues. Igniter failures, flame sensor corrosion, and induced-draft motor burnout are common in older gas furnaces. We also see heat exchanger stress from the temperature swings these masonry homes experience when attic ductwork lacks adequate insulation. Furnace Repair in Alamo Heights
AC Installation in Alamo Heights
AC installation in Alamo Heights is almost always a true retrofit project. Manual J load calculations are non-negotiable, original ductwork usually needs modification or replacement, and condenser placement must clear heritage tree restrictions. We handle the Alamo Heights permit pull, coordinate equipment delivery around narrow estate driveways, and size systems for the actual thermal load, not the square footage shortcut.

What Alamo Heights Customers Say
"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"Furnace wouldn't light the first cold morning. The guy walked me through what he was checking so I actually understood it. Replaced the igniter, wrote up the warranty, and it's been warm since."
