Coldharbour Heating & Air is an HVAC company serving Far North Dallas, TX, where we work on a lot of 1970s through 1990s single-family homes with attic-mounted systems and long duct runs. The defining feature of Far North Dallas HVAC work is age: many houses still run original equipment or mismatched components, and North Texas summers push those systems harder than almost anywhere else in the country. If your AC or furnace is acting up, call (430) 213-5796 and a live person answers, day or night.
Why Far North Dallas Homes Are Different
Far North Dallas is a patchwork of subdivisions built largely from the late 1960s through the 1990s. The typical home is brick veneer over frame, on a slab foundation, with the air handler or furnace in the attic and flex duct running through spaces that reach 140°F in July and August. That attic heat is the single biggest factor in how these systems age. Ductwork sweats, insulation compresses, and the system works against a thermal load that newer northern suburbs simply don’t have.
Many Far North Dallas homes still run R-22 systems, and we regularly see mismatched equipment: a new condenser sitting on a 20-year-old evaporator coil, or a furnace from one brand paired with a heat pump from another. In Prestonwood and Hillcrest, techs often find original 1980s Carrier and Trane units still chugging along because owners have patched them with aftermarket capacitors and contactors rather than replace them. That works until a capacitor fails on a 105°F Saturday and suddenly the whole neighborhood is calling at once.
Clay soil and high humidity add their own problems. Condensate drain clogs are common, and duct sweating can stain ceilings and breed mildew. Spring cold snaps and the occasional winter freeze, like the 2021 storm, expose systems that lack proper defrost controls or heat strip backups. The conversation in Far North Dallas is less about “what’s new” and more about “what’s going to keep working through the next heat wave.”
Styles & brands we work with






Our Main Far North Dallas Services
The three calls we take most often in Far North Dallas are for AC repair when a system quits mid-summer, furnace repair when a cold snap hits, and AC installation when an older R-22 unit has finally had enough. Each service has its own page with local pricing and detail.
AC Repair in Far North Dallas
Most AC repair calls in Far North Dallas start the same way: the thermostat is set to 74, the house is 82, and the outdoor unit is either silent or running but blowing warm air. The usual culprits are failed capacitors, contactors, and refrigerant leaks, especially on older R-22 systems where a recharge (topping off the cooling fluid your AC needs to run) can cost more than the leak repair itself. In midsummer, attic heat turns a simple repair into a miserable one for a homeowner doing it themselves, and a wrong diagnosis can cook a compressor. AC Repair in Far North Dallas covers pricing, common faults, and our 365-Day Done Right Promise on every repair we make.

Furnace Repair in Far North Dallas
Furnace work in Far North Dallas tends to be seasonal and sudden. Systems sit idle through long summers, then a November cold front or a January freeze lights them up and the failures surface: failed igniters, cracked heat exchangers, or blower motors that seize after months of disuse. Homes from the 1970s and 1980s often have furnaces that have never seen a proper annual check, which means small problems have had years to develop quietly. Furnace Repair in Far North Dallas explains what those repairs run, and what our written guarantee covers.

AC Installation in Far North Dallas
When a Far North Dallas homeowner replaces an R-22 system, the job is rarely a simple swap. The existing ductwork may be undersized or leaking, the electrical panel may need a new breaker, and the attic access may fight us the whole way. We quote a written price before any work begins, and that price accounts for the full scope: equipment, duct modifications, refrigerant, labor, and disposal of the old unit. For more on what a new system costs here, see AC Installation in Far North Dallas.

AfterPricing for HVAC Company in Far North Dallas, TX
| Service | Typical range in Far North Dallas |
|---|---|
| AC repair | $150 – $650 |
| Furnace repair | $150 – $700 |
| AC installation | $3,500 – $7,500 |
| Tune-up | $80 – $200 |
What pushes a Far North Dallas repair toward the top of those ranges is usually age and access. An R-22 system that needs refrigerant is inherently more expensive to top off because R-22 has been phased out, and an attic repair in August is harder, hotter work than a ground-level unit in October. We hand you a written price before any tool comes out, and that price does not change at the door.

What Far North Dallas Customers Say
"New AC and furnace. They gave me a written quote with a couple of options and no pressure. Showed up on the day they promised and the new system is so much quieter."
- Gloria Dunn"Repair was done right and the price was fair. Took a couple days to get on the schedule during the summer rush, which is understandable. Tech was sharp once he got here."
- Marty Whitcomb"Our upstairs never cooled right. He found the duct run was half blocked and the system low on charge, fixed both, and now the whole house is even. Explained every step."
