HVAC Company in Argyle, TX
Most HVAC calls in Argyle involve either an undersized builder system struggling to cool a 5,000-square-foot custom home or a rural propane furnace that quit during an ice storm. We’re Coldharbour Heating & Air, and our technicians work on both ends of that spectrum, sometimes on the same day. Dispatch and scheduling are coordinated from our Dallas-Fort Worth office, but our crews live and work in this area and know the difference between a Harvest subdivision three-zone system and a Cross Timbers ranch property on all-electric heat. Call us at (817) 402-2972 when you need a technician who understands what kind of house you’re actually living in.
Why Argyle Homes Are Different
Argyle sits in the Cross Timbers region of North Texas, where expansive clay soils shift with the seasons and can stress refrigerant line sets and duct connections where they pass near the foundation. That soil movement is not theoretical; we’ve found leaks in copper lines that traced directly to slab settlement patterns you don’t see in the Blackland Prairie suburbs to the south.
The housing stock here splits into two distinct categories. The dominant type is post-2010 custom and semi-custom construction on half-acre or larger lots, built to modern Texas energy codes but with floor plans so large that equipment selection errors compound quickly. Master-planned developments like Harvest brought homes routinely 3,500-6,000 square feet whose builder-spec HVAC systems were frequently undersized for actual conditioned square footage, including finished bonus rooms and converted spaces added after initial load calculations. It’s common to find three-car garages and upstairs game rooms that were conditioned as afterthoughts post-build, leaving the original single-zoned system chronically short. Our techs regularly retrofit ductless mini-splits into these spaces to compensate for what the original builder HVAC sub never accounted for.
The secondary stock is pre-boom ranch-era homes and farm properties, some still on propane or all-electric package units because natural gas lines never reached them. Summers here regularly exceed 100°F for extended stretches, and Argyle is squarely in the North Texas ice-storm belt, as February 2021 demonstrated. That event caused acute spikes in heat pump failures and frozen condensate drain calls that we still reference when sizing backup heat for local installations.
Our Main Argyle Services
Argyle homeowners call us most often for cooling repairs in July and heating failures after the first hard freeze. Each service has its own dedicated page with full pricing, brand coverage, and local specifics.
AC Repair in Argyle
AC repair in Argyle means working on systems that are often running at capacity from May through October. We see a lot of low refrigerant calls tied to line-set leaks from foundation settlement, and we see compressor strain on undersized units trying to cool 4,000 square feet with a 3.5-ton system that should have been 5 tons from the start. Our technicians carry common capacitors, contactors, and refrigerant for Goodman, Rheem, and York systems, which are prevalent in local new construction. AC Repair in Argyle

Furnace Repair in Argyle
Furnace repair here ranges from standard gas-igniter replacements in newer Harvest homes to propane conversion issues and electric heat-strip failures in rural properties. The 2021 ice storm taught us to check heat pump defrost boards carefully in this area, and we still find systems that were never properly configured for the defrost cycles North Texas winter demands. Every repair comes with our written 365-Day Done Right Promise. Furnace Repair in Argyle

AC Installation in Argyle
AC installation in Argyle requires accurate load calculation more than almost anywhere else we work. A 4,000-square-foot home with a 600-square-foot bonus room added after build is not a guesswork job. We measure every room, account for the three-car garage that shares a wall with conditioned space, and specify equipment that can handle 105°F afternoons without running continuously. We also handle rebate and financing paperwork for homeowners upgrading from builder-grade systems. AC Installation in Argyle

What Argyle 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"Furnace wouldn't light the first cold morning. The guy walked me through what he was checking so I actually understood it. Replaced the igniter, wrote up the warranty, and it's been warm since."
- Alicia Romero"AC died overnight with a newborn in the house. They bumped us up the list and had it running by noon. I about hugged the guy. Fair price even on a rush call."
- Celeste Ngo
