Coldharbour Heating & Air is an HVAC company serving Houston, TX, and we handle the repair and installation work that this city’s climate makes brutally specific. Houston’s five-month stretch of 90-plus-degree days, relentless humidity, and salt-laden Gulf air means a cooling system here takes a beating no manual ever prepared it for. We work on the 1970s through 2000s tract homes, the pier-and-beam bungalows inside the Loop, and everything between. If your AC quit or your furnace won’t light, call (832) 371-9862 and a live person answers. Every job gets a written price before work starts, and every repair is backed by our 365-Day Done Right Promise in writing.
Why Houston Homes Are Different
Houston’s housing stock is the product of unzoned, sprawling growth, and that shows up inside the walls. A huge share of homes here were built between the 1970s and early 2000s, many still running original equipment that was sized for a milder climate than the one we actually live in. Undersized return ducts are common. Flex duct routed through vented attics sweats, sags, and collects mold in ways you don’t see in cooler cities. In the inner-loop neighborhoods like The Heights, Montrose, and Timbergrove, those older pier-and-beam bungalows fight a different battle: crawlspace moisture wicking up into the home, and HVAC systems that were retrofitted into spaces never meant to hold them.
The climate writes the rest of the story. Houston’s latent load, the moisture the AC has to pull out of the air, is enormous. A system that cools the air but doesn’t dehumidify leaves a home feeling clammy at 72 degrees. Spring thunderstorms roll through and kill capacitors and control boards with power surges, especially in older neighborhoods with overhead lines. After a big storm, no-cool calls spike across the city, and techs who know Houston keep those parts on the truck. This isn’t a market where generic HVAC advice holds up. The work has to fit the house, the humidity, and the weather pattern.
Styles & brands we work with
Our Main Houston Services
Houston homeowners call us most often for two things: a cooling system that died in the heat, and a heating system that won’t fire when the rare cold snap hits. Each service has its own Houston page with full pricing and details.
AC Repair in Houston
AC repair in Houston is a same-day problem, not a schedule-it-for-later problem. When the outside unit’s capacitor blows after a thunderstorm or a contactor welds shut, the house heats up fast. We’ll find out more about common failures, what they cost to fix, and how our written 365-day guarantee works on the full AC Repair in Houston page. Every repair gets a price handed to you before work begins, and if it fails inside a year, we come back at no charge.
Furnace Repair in Houston
Houston furnaces sit idle for nine months, and that idleness creates its own failures: dirty flame sensors, weak igniters, and condensate lines clogged with the dust of a long cooling season. A furnace that won’t stay lit in January needs a tech who won’t treat it as an afterthought. The Furnace Repair in Houston page covers the common fixes, what they cost in this market, and how the same 365-Day Done Right Promise applies. We answer the phone 24 hours a day, because a cold Houston house is a miserable one.
AC Installation in Houston
A proper Houston installation means sizing for humidity, not just temperature. Oversized units short-cycle, never dehumidify, and fail early. Undersized units run nonstop from May to September. We’ll walk through what a correctly sized system costs here, how we handle the load calculation, and what the installation process looks like on the AC Installation in Houston page. Written price before we start, a set install date, and no surprises at the door.

AfterPricing for HVAC Company in Houston, TX
| Service | Typical range in Houston |
|---|---|
| AC repair | $150 – $650 |
| Furnace repair | $150 – $700 |
| AC installation | $3,500 – $7,500 |
| Tune-up | $80 – $200 |
What pushes a Houston repair toward the top of that range is usually access and age. A condenser squeezed into a side yard behind a gate, or a 25-year-old system that needs multiple parts replaced, costs more than a clean, straightforward capacitor swap. The price is still written down and handed to you before any work begins, and it does not change at the door. That’s the Kingswell Way, and it’s not optional with us.

FAQs About HVAC Company in Houston
For AC repair calls during Houston’s cooling season, we aim for same-day service across most of the city. A live person answers the phone 24/7, so you’re never waiting on a callback to find out when we can come. Call (832) 371-9862 for the current window.
The City of Houston requires permits for most HVAC installations and some larger repairs. We handle the permit paperwork on installation jobs as part of the project, and we’ll tell you before work starts exactly what’s required for your address.
Houston’s latent load, the moisture in the air your system has to remove, is unusually high. A unit that’s oversized, or has dirty coils or low refrigerant, will cool the air without dehumidifying it properly. We check this on every tune-up and repair call.
If your system needs work or you just want a straight answer about what it’ll cost, call Coldharbour Heating & Air at (832) 371-9862. We’ll give you a written price, a firm arrival window, and a guarantee in writing before the technician leaves.

What Houston Customers Say
"AC quit on the hottest day of the year of course. Coldharbour had a tech out that evening, found a bad capacitor, and had us cool again within the hour. Charged the quote, not a penny more."
- Doug Feeney"Our upstairs never cooled right. He found the duct run was half blocked and the system low on charge, fixed both, and now the whole house is even. Explained every step."
- Deanna Boleyn"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
