Channelview sits right on the Houston Ship Channel, and that location shapes every heating and cooling job we do here. Homes in this part of east Harris County are mostly 1960s-to-1980s brick and frame construction on slabs, built for a petrochemical workforce, with aging ductwork and air conditioners fighting a constant battle against salt air, sulfur compounds, and Gulf humidity. The result is that HVAC work in Channelview looks different than it does five miles west: coils corrode faster, drain pans grow mold sooner, and equipment that would run fine in Pasadena fails early here. We’re Coldharbour Heating & Air, and if your AC or furnace is struggling in Channelview, call us at (832) 371-9862.
Why Channelview Homes Are Different
The big factor is the air itself. Channelview’s prevailing southeast wind carries salt spray and refinery particulate from the Ship Channel straight across residential streets, and that means condenser coils and fins on the east side of town can show pinhole leaks in copper tubing within five to seven years. The same equipment five miles west might last twice as long. Galvanized sheet metal on outdoor units, the aluminum fins, even the copper line sets are all being worked on by airborne chlorides and hydrocarbon residues. Homeowners in Channelview who skip coil cleaning for a season often find themselves replacing a coil, not just washing one.
Inside the house, the original ductwork from the 60s, 70s, and 80s is another story. Many of these brick-and-frame ranchers were built fast, during boom years, with undersized return plenums and flex runs that were never sized for the airflow a modern high-efficiency system needs. Add Gulf moisture and high latent heat loads to that, and you get a house that struggles to dehumidify even when the AC is blowing cold. The cooling season here runs realistically from March through November, and any system working in Channelview needs its drain pan treated for microbial growth, its coil kept clean, and its charge checked against the actual heat load the house carries in July.
Styles & brands we work with
Our Main Channelview Services
Most Channelview homeowners call us first about one of two things: an air conditioner that quit during a heat wave, or a furnace that won’t fire on the first cold snap in December. We also replace full systems. Each of these services has its own detailed Channelview page linked below.
AC Repair in Channelview
Air conditioning in Channelview runs hard from March to November, often around the clock in a stretch of 95-degree days backed by high humidity. When a system fails, the first call is usually about blowing warm air, a frozen coil, or a compressor that clicks but won’t start. We inspect the condenser for the corrosion and coil damage this area is known for before we quote a repair. If a capacitor or contactor has failed, we can usually have it running the same visit. If the copper tubing has begun to leak from the salt and chemical exposure, we’ll show you the leak and give you a written price to repair or replace. See the full breakdown on our AC Repair in Channelview page.
Furnace Repair in Channelview
Channelview winters are short but not gentle. The first real cold snap usually arrives in December or January, and that’s when furnaces that have sat idle since March show their age. We see igniters that cracked from repeated cycling, flame sensors coated with petrochemical dust that drifted in from the Ship Channel corridor, and heat exchangers that rusted faster than expected in the humid air. Every repair gets a written 365-day guarantee, and we show up with a firm arrival window, not a four-hour spread. For a full list of the furnace repairs we handle here, visit our Furnace Repair in Channelview page.
AC Installation in Channelview
Replacing a system in Channelview means matching a new condenser and air handler to a house that was built for an old R-22 system and ductwork that may be undersized. We measure the return and supply side before we recommend equipment, because putting a high-efficiency unit on undersized ductwork costs you money in lost airflow, higher static pressure, and poor dehumidification. The corrosion problem also informs our equipment recommendations: many Channelview homeowners choose models with coated coils or extended coil protection, simply because the local air is that hard on copper and aluminum. See AC Installation in Channelview for pricing and the installation process.

AfterPricing for HVAC Company in Channelview, TX
These are the ranges we typically see for HVAC work in Channelview. The final written price depends on your equipment, the condition of the ductwork, and what we find when we open the system up.
| Service | Typical Range in Channelview |
|---|---|
| AC repair | $150 – $650 |
| Furnace repair | $150 – $700 |
| Full AC installation | $3,500 – $7,500 |
| Seasonal tune-up | $80 – $200 |
What pushes a Channelview job toward the top of those ranges is usually corrosion damage, which adds coil cleaning, coil replacement, or refrigerant repair, and ductwork that needs sealing or resizing before a new system will perform. Whatever the job, the written price is in your hand before any tool comes out, and that number does not change at the door.

It does. Airborne chlorides and sulfur compounds from the Ship Channel can corrode condenser coils and fins noticeably within five to seven years. That’s why regular coil cleaning matters more here than almost anywhere else in the Houston metro, and why we recommend coated coils on replacement systems.

What Channelview Customers Say
"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"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."
