AfterHVAC Company in Austin, TX
Most HVAC repairs in Austin run $150-$700 and same-day appointments are available when you call (817) 402-2972. Austin’s combination of 100°F+ summers, slab-on-slab construction with attic ductwork, and a post-2021 awareness of heating vulnerability makes this market unlike anywhere else in Texas. At Coldharbour Heating & Air, we dispatch from our Austin office and our technicians carry parts for the nine brands we see most often in Travis County homes.
The name Coldharbour comes from the roadside shelters travelers once used to wait out bad weather. That’s still the job: keeping Austin homes comfortable when the cedar pollen hits in January or when the thermometer pushes 105°F in August. Every repair we complete carries our 365-Day Done Right Promise in writing, and every homeowner gets a fixed price before we touch a single tool.
Why Austin Homes Are Different
Austin’s housing stock splits sharply down the middle. In Allandale, Brentwood, and Cherrywood, you’re looking at 1950s-1970s slab-foundation ranch homes with original attic flex duct that has cooked through 60-90 consecutive days above 100°F every summer. Those attics hit 150°F regularly, degrading mastic seals and refrigerant-line insulation far faster than in cities where ductwork runs through basements or conditioned crawl spaces. We’ve replaced duct runs in Crestview that were literally crumbling to the touch after twenty years of thermal cycling.
The 2000s-2020s growth wave, Mueller and the Domain-area subdivisions, brought code-mandated higher-efficiency equipment and tighter envelopes. Same city, completely different service profile. Then there’s the Austin-specific winter factor: cedar fever season, when Ashe juniper pollinates from late December through February, drives a concentrated indoor air quality surge that doesn’t exist in Dallas or Houston. Local techs who know the market start talking MERV-13 filters and whole-home air scrubbers in November, before the pollen counts spike.
The 2021 Winter Storm Uri changed the conversation permanently. Most Austin homes were built with strip-heat-only or severely undersized heating systems, and a week-long hard freeze exposed the gap. Heating capacity upgrades are now a year-round discussion here, not just a fall conversation.
Our Main Austin Services
These are the three calls we field most often from Austin homeowners. Each has its own page with deeper detail on what to expect.
AC Repair in Austin
When an Austin AC fails in July, it’s not a comfort issue; it’s a health risk for young children and older adults. Our trucks carry capacitors, contactors, and refrigerant for the Goodman and Rheem systems we see constantly in the 78752 and 78757 ZIP codes. Most calls are same-day, and we always check attic duct condition while we’re on the roof, because degraded flex duct is often the real culprit behind a “broken” air conditioner. AC Repair in Austin
Furnace Repair in Austin
Post-Uri, Austin furnace calls increasingly involve heat strips that can’t keep up or gas furnaces that were never properly sized for the home’s actual load. We see a lot of failed sequencers in Mueller-area townhomes and ignition failures in the older Brentwood ranches. Every repair gets a written 365-Day Done Right Promise, and we flag undersized systems before they leave you cold again. Furnace Repair in Austin
AC Installation in Austin
New system installs in Austin require load calculation, permit pull, and often duct replacement in that 150°F attic. We don’t promise same-day installation; we promise a written fixed price, a scheduled install date, and rebate paperwork handled. The split market means we size differently for a 1960s Allandale ranch with original duct than for a 2019 Domain-area build with tight construction and existing high-velocity lines.

We also service Carrier, York, Daikin, Bryant, and American Standard. Most same-day repairs happen because the part is already on the shelf, not on order. our brands

Attic access difficulty and ductwork condition push Austin prices toward the higher end; a repair in a 150°F attic with degraded flex duct often reveals secondary issues. We hand you a written price before any work begins, and that number does not change when the technician finishes.

FAQs About HVAC Company in Austin, TX
Same-day service is available for most AC and furnace repair calls when you reach us by early afternoon. Our Austin office dispatches with 2-4 hour arrival windows for urgent calls. Call (817) 402-2972 to check today’s availability.
AC installation and furnace replacement require a City of Austin permit; repairs typically do not. We pull permits as part of every install and schedule the required inspection. Your HOA may have additional equipment-placement rules, especially in newer subdivisions like Mueller.
Slab construction with attic ductwork exposes Austin homes to extreme temperature swings: 150°F attic air in summer and, post-2021, awareness that undersized heating systems can’t handle hard freezes. Many homes need both duct repair and proper load calculation, not just a bigger unit.

What Austin Customers Say
"The repair was done well and quickly. Scheduling over the phone was a little clunky and I got transferred twice, but the tech himself was great and on time."
- Brett Haygood"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."
