Tomball isn’t one kind of town anymore, and that matters when your air conditioner or furnace stops working. The same service route can take our technicians from a 1970s ranch home with original ductwork to a brand-new house in Amira with a zoned heat pump system. The job is different at each stop, and the price should be too. Coldharbour Heating & Air handles both ends of that spectrum, and every visit starts the same way: a live person answers the phone, and the written price comes before the work. When the humidity hits in June and your AC quits, call (832) 371-9862.
Why Tomball Homes Are Different
Tomball’s shift from a small railroad town to a Houston exurb has left the housing stock split in two. The older core, built mostly from the 1960s through the 1980s, is full of ranch-style homes on pier-and-beam foundations. Many still have attic-installed furnaces and ductwork that was sized for a different era, which means airflow problems are common even when the equipment itself is healthy. Newer subdivisions like Willow Creek and Amira sit on slab foundations with high-efficiency heat pumps and zoned controls. We see both on the same day, and they fail differently.
The climate adds another layer. Tomball’s humid subtropical weather keeps air conditioners running nine or ten months a year. Here, the bigger challenge is usually latent load, which is the industry term for pulling moisture out of the air, not just lowering the temperature. Spring storms bring power surges that knock out control boards and capacitors. And in older Tomball neighborhoods, many homes still run R-22 systems. Since the 2020 refrigerant phaseout, a recharge can run about $200 per pound, and drop-in replacements can void the manufacturer’s warranty. Our trucks carry multiple refrigerant options so we can lay out the real cost of each path before you commit to anything.
Styles & brands we work with
Our Main Tomball Services
Most calls we get from Tomball homeowners come down to two things: an air conditioner that died in summer or a furnace that won’t fire in winter. The third big service, full system replacement, usually starts with one of those two calls. Here’s what each involves here.
AC Repair in Tomball
Air conditioning in Tomball gets worked harder than in most of the country, and the humidity here finds weak points fast. A coil that’s slightly undercharged, a drain line that’s starting to clog, a capacitor that’s lost a few microfarads, any of those will show up as a hot, sticky house within a couple of days. Most repairs are quicker than homeowners expect, but running an AC hard for ten months a year means we also find systems where repair no longer makes sense. We’ll tell you straight, with the numbers on paper. AC Repair in Tomball
Furnace Repair in Tomball
Tomball winters are short but they can bite. A furnace that hasn’t run since February gets asked to fire in November, and that’s when dirty flame sensors, failing igniters, and old draft inducer motors show themselves. Many Tomball furnaces sit in attics, which means heat cycles are extreme even by Texas standards. We fix all nine major brands, and every furnace repair gets the same written 365-day guarantee as any other job we do. Furnace Repair in Tomball
AC Installation in Tomball
Replacing a system in Tomball usually means choosing between a like-for-like swap and a real efficiency upgrade. In older homes with existing ductwork, sometimes the smart move is a 14 SEER system that fits what’s already there. In newer Tomball houses with zoned heat pumps already in place, a high-efficiency replacement with the right capacity sizing can cut summer bills noticeably. We size every job with a load calculation, not a guess, and the written price covers the full scope before we start. AC Installation in Tomball

What pushes a Tomball job toward the top of those ranges? Age of the equipment, accessibility (attic furnaces take longer to reach than closet units), and whether refrigerant is involved. The bigger variable is whether a repair is worth doing at all. We hand you the written price before any work begins, so the number you see is the number you pay. That’s the whole point of the way we operate.

Yes. On every job, the price is written down and handed to you before the first tool comes out. It does not change at the door. That’s a core part of how Coldharbour Heating & Air operates, and it’s been that way since Victor Mancini established the company’s standards under the Kingswell network.

What Tomball 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"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."
