Coldharbour Heating & Air is the Austin HVAC company that puts every price, arrival window, and repair guarantee in writing before the work begins. Austin homes ask more of an HVAC system than most: a humid subtropical climate means over 100 days above 90°F, and the housing stock swings from 1920s bungalows with original ductwork to tightly sealed new builds in Steiner Ranch. That spread of conditions is exactly why our technicians carry the tools and training to work on nine major brands. If your system is struggling, call (361) 204-1605 and a live person answers.
Why Austin Homes Are Different
Austin’s growth pattern created an unusual patchwork: historic homes in Hyde Park and Travis Heights sit on ductwork designed for a different climate, while 1970s-era houses in Northwest Hills were built for cheaper energy and smaller cooling loads. Meanwhile, the newest communities like Circle C and Steiner Ranch are sealed tight for efficiency but can trap humidity when a system is even slightly oversized. The Hill Country’s heat and humidity punish any weak point, whether that is a corroded coil, an original single-pane window, or a condenser choked with oak pollen and limestone dust. In older central neighborhoods around The Drag and downtown, the heat island effect pushes rooftop temperatures several degrees higher than the official forecast, so an undersized unit that passes inspection in March can fail outright by July. Technicians who work Austin regularly see the same patterns: high-humidity short-cycling, hard-start failures during sudden cold snaps, and overworked blowers in homes with original duct runs that were never balanced for a heat pump. None of this is generic; it is the local reality of cooling and heating a city built across three distinct housing eras, and it changes which repairs make sense and which replacements will actually hold up.
Styles & brands we work with
Our Main Austin Services
Most calls we answer in Austin fall into two groups: a system that quit working at the worst possible moment, and a system that is being replaced because it cannot keep up anymore. Here is where each job starts.
AC Repair in Austin
When a central air system fails during an Austin summer, the clock is the whole game. Our technicians diagnose the most common local failures first: capacitor and contactor breakdowns from months of continuous run time, condensate line clogs from high humidity and dust, refrigerant leaks at brazed joints, and condenser coils fouled by oak pollen and cottonwood. After a diagnosis, you get a written price before any work starts, and the repair itself is backed by our 365-Day Done Right Promise. For the full picture on repair costs, symptoms, and warranty coverage, see AC Repair in Austin.
Furnace Repair in Austin
Austin furnaces mostly sit idle nine months a year, which creates its own failure pattern: dust settles into burners, pressure switches stick, and igniters crack from heat cycling that starts suddenly in late fall. Our technicians check the ignition sequence, safety sensors, and heat exchanger before quoting any repair, because a furnace problem always involves combustion safety. If the repair fails inside 365 days, we return and make it right at no charge. The full breakdown is on Furnace Repair in Austin.
AC Installation in Austin
Replacing a system in Austin often means correcting what a previous builder or owner got wrong: ductwork that was undersized for the heat load, a condenser placed against a west-facing wall, or a single-zone system trying to cool a two-story addition. We size equipment with a load calculation rather than a guess, and we discuss heat pump and dual-fuel options with homeowners who want to stop dreading their August electric bill. Every install carries a written price before work starts and a set install date. Details on system options and rebate paperwork live on AC Installation in Austin.

What moves a job to the top of that range in Austin is usually access, age, and location: a condenser wedged into a fenced side yard in a 1920s Hyde Park bungalow takes longer to reach than a ground-level unit in Circle C, and a repair on a system with original cast-iron ductwork may need extra care to protect what is already fragile. That is why we hand you a written price before a single tool comes out, so the number you agree to is the number you pay.

What Austin Customers Say
"New AC and furnace. They gave me a written quote with a couple of options and no pressure. Showed up on the day they promised and the new system is so much quieter."
- Gloria Dunn"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"Thermostat kept losing its mind. He swapped it, showed me how to use the new one, and didn't charge for a bunch of extras. In and out, friendly, done."
- Paula Kingston
