AfterHVAC Company in Kirby, TX
Most HVAC calls in Kirby aren’t about fancy equipment. They’re about ranch-style homes built between the 1940s and 1970s with attic flex duct cooking at 140°F and single-stage AC units that weren’t sized for modern cooling loads. Coldharbour Heating & Air handles AC repair, furnace repair, and AC installation here, and our technicians know the permit landscape that trips up outside contractors. We’re independently owned and operated as part of the Kingswell network, with dispatch coordinated from our San Antonio office and crews serving Kirby directly. Call (817) 402-2972 when you need a live person, any hour.
Why Kirby Homes Are Different
Kirby sits as a fully independent municipality completely surrounded by San Antonio, which creates a permit situation that confuses contractors who don’t work here regularly. A technician can cross the Kirby city boundary mid-block with no visible marker. One side of the street needs a Kirby city permit and Kirby inspection; the other needs San Antonio’s. We’ve seen stop-work orders on otherwise straightforward changeouts because a contractor pulled the wrong permit without checking the parcel jurisdiction first.
The housing stock reinforces the challenge. Kirby’s residential core is post-WWII ranch construction with low-pitched attics, minimal insulation, and attic-run flex duct that degrades faster than in newer builds. During summer, those attic spaces hit 140-150°F, accelerating duct deterioration and making cooling loads heavier than the original systems were designed to handle. Embedded in San Antonio’s east-side urban heat island, Kirby sees outdoor heat indexes regularly exceeding 105°F from May through September, with condensing units running near-continuously. February 2021’s Winter Storm Uri also exposed how few older Kirby homes had adequately protected refrigerant lines or heat-pump backup heat. These aren’t abstract concerns. They determine whether a repair lasts or fails, and whether a new system is sized correctly.
Our Main Kirby Services
Homeowners in Kirby call us most often for cooling repairs in peak summer, heating repairs during freeze events, and full system replacements when aging equipment finally gives out. Each service has its own dedicated Kirby page with deeper detail.
AC Repair in Kirby
AC repair in Kirby typically involves refrigerant leaks, failed capacitors, or compressor strain from near-continuous summer operation. We also find crushed or disconnected flex duct in those hot attics, which homeowners sometimes mistake for equipment failure. Our technicians carry capacitors, contactors, and refrigerant to restore cooling the same day when possible. Every repair comes with a written 365-Day Done Right Promise. AC Repair in Kirby
Furnace Repair in Kirby
Furnace repair here means addressing igniter failures, flame sensor corrosion, and heat exchanger cracks in aging gas furnaces, plus occasional heat-pump defrost board failures on systems that doubled as cooling units all summer. After Winter Storm Uri, we’ve also replaced more frozen and burst refrigerant lines than in previous years. We stock igniters, flame sensors, and defrost controls for faster turnaround on common failures. Furnace Repair in Kirby
AC Installation in Kirby
AC installation in Kirby requires verifying parcel jurisdiction before pulling permits, sizing systems for actual cooling loads including duct condition, and often replacing degraded attic flex duct as part of the job. We perform load calculations, provide a written fixed price before ordering equipment, and schedule installation once permits are correct. We handle rebate and financing paperwork for qualifying equipment. AC Installation in Kirby

FAQs About HVAC Company in Kirby
You need a Kirby city permit if your property sits inside Kirby’s municipal boundaries, even if the street looks identical to surrounding San Antonio neighborhoods. We verify parcel jurisdiction before pulling any permits to avoid stop-work orders or failed inspections.

For emergency no-cool or no-heat situations, we prioritize based on health and safety risk, especially during extreme heat or hard-freeze events.

What Kirby 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."
