HVAC Company in Canyon Lake, TX
Most HVAC calls in Canyon Lake involve homes that started as 1960s weekend cabins, not houses built for year-round central air. That means our technicians spend a lot of time retrofitting ductwork into tight crawl spaces, sizing systems for uninsulated lake-cabin walls, and replacing window units with central AC or ductless mini-splits. We’re Coldharbour Heating & Air, and we dispatch crews to Canyon Lake from our San Antonio scheduling office. If you need a repair or a new system, call us at (817) 402-2972 and a live person will pick up, day or night.
Why Canyon Lake Homes Are Different
Canyon Lake sits where the Army Corps of Engineers dammed the Guadalupe River in 1964, and the original housing stock reflects that history. Most of the lakefront and hillside properties were built as seasonal retreats with pier-and-beam foundations blasted into caliche and limestone, minimal insulation, and no ductwork. Retirees and remote workers have converted thousands of these cabins to full-time homes since 2020, which creates a specific kind of HVAC work: first-time central system installs where none existed, mini-split retrofits to avoid tearing out rock walls, and upsized equipment to overcome heat gain from uninsulated roofs.
The lake itself changes the load calculation. Canyon Lake’s reservoir surface pushes local humidity higher than drier Hill Country towns to the north, so cooling systems here work harder at moisture removal, not just temperature drop. Summer highs hit the mid-to-upper 90s°F routinely. In winter, hard freezes catch owners off guard when cabins sit empty for weeks; unprotected refrigerant lines and condensate drains crack, and we get emergency no-heat calls from owners who’ve just arrived for a holiday weekend.
The short-term rental economy adds another wrinkle. An Airbnb that sits dark for three weeks, then runs at full occupancy through a July 4th weekend, cycles its compressor far more aggressively than a steady-occupancy home. We see refrigerant leaks and premature compressor failures in rental properties at twice the age we’d expect from normal wear.
Our Main Canyon Lake Services
Homeowners in Canyon Lake call us most often for these three jobs. Each has its own page with detailed pricing, local conditions, and what to expect.
AC Repair in Canyon Lake
AC repair calls here usually trace back to one of three Canyon Lake patterns: a rental unit that was pushed hard after sitting idle, a converted cabin whose original ductwork can’t handle a modern heat load, or freeze damage to an outdoor condensate line from a January cold snap. Our technicians carry capacitors, contactors, and refrigerant for Trane, Lennox, Goodman, and Rheem systems on every truck, and we stock common compressor parts locally so we’re not waiting on a San Antonio warehouse for a weekend repair. AC Repair in Canyon Lake covers typical failure modes, what we check first, and exact pricing.

Furnace Repair in Canyon Lake
Furnace work in Canyon Lake splits between older gas wall heaters in original cabins and newer central furnaces in converted or rebuilt homes. The wall heaters often fail at ignition after years of intermittent use, while central systems suffer from clogged condensate traps or cracked heat exchangers in rental properties where filters were neglected. We test carbon monoxide levels on every gas heating call, and we won’t run a furnace with a compromised heat exchanger, period. Furnace Repair in Canyon Lake explains what we find, what it costs, and how fast we can get there.

AC Installation in Canyon Lake
New AC installation in Canyon Lake is rarely a simple swap. On original lake cabins, we’re often running ductwork for the first time through pier-and-beam crawl spaces with 18 inches of clearance, or recommending ductless mini-splits to avoid tearing into rock-lath walls. Even on newer homes, the steep lots and tight lakefront setbacks can complicate crane placement for rooftop package units. We perform a full Manual J load calculation on every install, accounting for the local humidity load and any insulation upgrades the homeowner has done. AC Installation in Canyon Lake walks through the process, timing, and rebate paperwork we handle.

What Canyon Lake Customers Say
"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."
- Alicia Romero"AC died overnight with a newborn in the house. They bumped us up the list and had it running by noon. I about hugged the guy. Fair price even on a rush call."
