Coldharbour Heating & Air is the HVAC company Dickinson homeowners call when a system quits in July or a furnace won’t light in January. We work on the aging 1970s-1990s brick veneer and frame homes that make up most of this town, where original R-22 systems and ductwork sized for drier loads mean coil freezing, humidity complaints, and uneven cooling are daily realities. Our technicians live with the same salt-laden Gulf air you do, and they know what it does to a condenser. If you need a straight answer about your system, call (832) 371-9862 and a person picks up.
Why Dickinson Homes Are Different
Dickinson sits just inland from Galveston Bay, and that geography writes the whole story for HVAC work here. High humidity and salt spray ride in from the coast year-round, and summer heat indexes regularly push past 105°F. The result is two problems at once: outdoor units corrode faster than almost anywhere else in the Houston metro, and indoor humidity control becomes a health and comfort issue, not just a preference.
The housing stock compounds it. Most Dickinson homes went up between the 1970s and 1990s, and a surprising number still run on original R-22 systems. Those units were matched to ductwork that was never designed for our humidity loads, so homeowners often see coil freezing in the afternoon heat and sticky indoor air even when the thermometer says the house is cool. Add in the prevailing bay breezes that push salt spray against the east and south sides of homes, and we routinely find condenser fins on those exposures pitted and crumbling within 5-7 years while the rest of the unit looks nearly new. Locals call it “bay rot,” and it’s the single most common reason a Dickinson AC dies before its time.
What that means for you: corrosion-resistant coatings and annual coil cleaning aren’t optional upgrades here. They’re the difference between a condenser that lasts 8 years and one that lasts 15. When we quote a repair or replacement in Dickinson, we’re looking at your specific exposure, not just the system’s age.
Styles & brands we work with
Our Main Dickinson Services
Dickinson homeowners call us most often for two things – a cooling system that failed in the heat, and a furnace that won’t fire on the first cold morning. AC installation closes out the three, and each has its own Dickinson page with local pricing and timelines spelled out.
AC Repair in Dickinson
Most AC repair calls in Dickinson start the same way: the thermostat says 78, the air coming out of the vents feels warm, and the unit outside is either rattling or silent. In this climate, the culprit is often salt-corroded condenser coils or a low refrigerant charge (the cooling fluid your system needs to move heat out of the house). We diagnose the actual fault, hand you a written price before any tool comes out, and stand behind the repair for a full 365 days. Full details on cost ranges and same-day response are on the AC Repair in Dickinson page.
Furnace Repair in Dickinson
Dickinson winters are short but they’re not gentle, and when a furnace won’t light, the house gets uncomfortable fast. The systems we see are mostly gas furnaces paired with older ductwork, and the common failures are igniters, flame sensors, and control boards that don’t love the humidity swings we get all winter. Every repair gets a written 365-day guarantee before the technician leaves, and our people are trained on Lennox, Goodman, Rheem, and York so the brand already in your home isn’t a problem. See typical local pricing and what a repair visit involves on the Furnace Repair in Dickinson page.
AC Installation in Dickinson
Replacing a system in Dickinson isn’t just swapping boxes. It means sizing the unit for our humidity, which is a different calculation than the contractor in a dry inland town would run. It also means looking at where the condenser sits relative to the bay breeze, because a unit placed on the east or south exposure without protection is going to corrode years early. We provide a written fixed price, a set install date, and we handle rebate paperwork. The AC Installation in Dickinson page walks through system options and Dickinson-specific pricing.

What pushes Dickinson prices to the upper end is almost always corrosion or deferred maintenance: a coil that’s been eaten by salt spray, a system that hasn’t been cleaned in years, or ductwork that needs sealing to handle our humidity. Whatever the number, you get it in writing before any work begins, and it doesn’t change at the door.

FAQs About HVAC Company in Dickinson
AC and furnace repair calls in Dickinson are typically answered same-day, often within a few hours depending on when you call. Phones are answered by a person 24 hours a day, so an evening failure doesn’t wait until morning. Call (832) 371-9862 and we’ll give you a firm window.
Permit requirements vary by scope of work, and Dickinson follows Texas licensing standards for HVAC contractors. We handle permitting on installations and major replacements so the paperwork isn’t something you chase. On repairs, permits are rarely required, and we’ll tell you plainly if one applies to your job.
Annual coil cleaning and a corrosion-inhibiting treatment on the condenser are the two most effective steps for Dickinson homes. If your unit sits on the east or south exposure facing the bay breeze, ask us about a protective coating during your next visit. It adds years to a condenser in this climate.

What Dickinson Customers Say
"New mini split for the addition. Clean install, on time two days running, and the price matched the written quote to the dollar."
- 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."
- Natalie Esposito"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."
