Coldharbour Heating & Air is an HVAC company serving Alvin, TX, providing AC repair, furnace repair, and AC installation with a written price handed to you before any work begins. Alvin’s position near the Gulf Coast means outdoor condenser coils take a beating from salt-laden air and brutal humidity, while older homes near the historic downtown often carry ductwork that was undersized fifty years ago. We’re an independently owned and operated member of the Kingswell network, founded in 2003, and every repair we do is covered by a written 365-day guarantee. If you need a technician in Alvin, call (832) 371-9862 and a live person answers, day or night.
Why Alvin Homes Are Different
Alvin’s humid subtropical climate doesn’t give HVAC systems much of a break. Summers run long and sweltering, with heat indexes routinely past 100°F, and even the mild winters leave systems running more days than they rest. That’s hard on equipment, but what really separates Alvin from neighboring suburbs is the housing stock. The city mixes early 20th-century bungalows on pier-and-beam foundations with 1980s and 2000s tract homes on slabs, plus a growing number of newer energy-efficient builds on the outskirts. Each of those home types presents a different set of ductwork and airflow problems, and a technician who treats them all the same is going to miss something.
The older homes are where we see the most avoidable failures. Many still have original galvanized ductwork in the attic, and in Alvin’s humidity that metal corrodes from the inside out. Condensation collects, rust forms, and by the time peak cooling season arrives, the system is leaking conditioned air into the attic and pulling in moisture. Those leaks only become obvious when the AC can’t keep up in August. Newer homes have their own issues: airtight construction is great for efficiency, but it makes proper refrigerant charge and airflow measurements even more critical, because a small imbalance shows up fast as uneven cooling between rooms.
Styles & brands we work with
Our Main Alvin Services
These are the three calls we take most often from Alvin homeowners. Each service has its own page with pricing, local specifics, and what to expect from the first visit.
AC Repair in Alvin
When an air conditioner quits in Alvin in July, the house becomes unbearable within hours. Most of the calls we get involve failing capacitors, refrigerant leaks, or condenser coils that have corroded faster than expected because of the salt and humidity in the air near the Gulf. We diagnose the exact failure, give you a written price before we touch a tool, and cover every repair with our 365-Day Done Right Promise. If the same issue comes back within a year, we return and fix it at no charge. Learn more on our AC Repair in Alvin page.
Furnace Repair in Alvin
Furnace failures in Alvin tend to catch people off guard. Winters are mild, so the heating system sits idle for long stretches, and ignition components, flame sensors, and blower motors can develop problems quietly while no one is paying attention. Then a cold snap hits and the furnace won’t fire. Our technicians work on all the major residential brands, and we give every furnace repair the same written 365-day guarantee we put on cooling work. The specifics are on our Furnace Repair in Alvin page.
AC Installation in Alvin
Replacing an air conditioner in Alvin isn’t a one-size-fits-all job. Older bungalows near the historic downtown often need custom duct retrofits before a modern high-efficiency unit can work properly, while newer homes may need nothing more than a clean swap. Either way, the job starts with a load calculation, not a guess, and you’ll get a written fixed price and a set install date before we order anything. Details and pricing ranges are on our AC Installation in Alvin page.

What pushes a job toward the higher end of a range in Alvin is usually the age of the home. Older houses with corroded ductwork or retrofitted systems take more labor, and coastal humidity means some condenser components need replacement rather than cleaning. Whatever the number turns out to be, you’ll see it in writing before we start, and that price won’t change at the door. Call (832) 371-9862 for a free estimate.

- Yvonne Prewitt"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."
