Farmers Branch homeowners call us for one thing more than anything else: an air conditioner that quit on a 102-degree afternoon. The homes here – most built between the 1950s and 1970s – run cooling systems hard for seven months a year, and when they fail, waiting isn’t an option. We’re Coldharbour Heating & Air, an independently owned and operated member of the Kingswell network, and we fix, replace, and maintain HVAC systems across Farmers Branch with one simple promise: a written price before the work starts, and a written 365-day guarantee on every repair. Call (430) 213-5796 and a live person answers, day or night.
Why Farmers Branch Homes Are Different
Farmers Branch sits in a sweet spot of North Texas heat: long, humid summers that routinely push past 100°F, paired with short, mild winters. That means the AC does the heavy lifting year-round, while the furnace runs just enough to keep the chill off in January. Most of the housing stock is single-family ranch and traditional homes from the 1950s through the 1970s, many sitting on concrete slab foundations. That slab construction matters more than most homeowners realize: it forces ductwork into tight attic spaces and chases, and after five or six decades of North Texas humidity, the galvanized ductwork in the older neighborhoods north of I-635 is often rusted through or leaking badly. We regularly find return air choked by undersized flex duct that a past remodel never addressed – which is exactly why those same homes freeze up on the hottest afternoons. Add in the city’s proactive code enforcement and rebate programs that nudge homeowners toward high-efficiency replacements, and you get a community where retrofits are the norm, not the exception.
Styles & brands we work with
Our Main Farmers Branch Services
Most calls from Farmers Branch fall into two buckets: the AC stopped cooling, or it’s time to replace it. The furnace gets its turn in the short winter months. Here’s what each of those jobs actually looks like in this city.
AC Repair in Farmers Branch
When a compressor won’t start or a coil has frozen solid, the heat doesn’t wait for a convenient time. Most AC repair work in Farmers Branch runs $150 – $650 depending on what’s failed – a capacitor replacement sits at the low end, a failed compressor or a refrigerant leak repair (fixing the line that carries your cooling fluid) lands higher. In the ranch homes north of I-635, we look first at airflow: undersized return ducts from past remodels starve the system and freeze coils. We diagnose it, write the price down, and only start work once you’ve approved it. Full details on what we see and fix here: AC Repair in Farmers Branch.
Furnace Repair in Farmers Branch
Farmers Branch winters are brief, which means furnaces sit idle for months and then get asked to perform on the first cold snap. Igniters, flame sensors, and blower motors are the usual suspects, with most repairs running $150 – $700. In homes from the 1960s and 1970s, we often find heat exchangers that have been running for 40+ years and were never inspected because the previous owner didn’t think the furnace mattered in Texas. A failed igniter on a January morning is a genuine emergency when the overnight low drops below freezing. See what’s involved: Furnace Repair in Farmers Branch.
AC Installation in Farmers Branch
Replacement is a bigger decision here because the cooling load is so severe. Most full AC installations in Farmers Branch land between $3,500 and $7,500 depending on system size, efficiency rating, and whether the ductwork needs work. Many original systems in these 1950s and 1960s ranches were sized for a cooler era, and we frequently see homes where the condenser is simply undersized for the square footage. We measure before we quote – no guesswork, no “same size as the old one” shortcuts. The written price covers everything: equipment, labor, refrigerant, and the cleanup.

Brands We Service in Farmers Branch
Our technicians work on whatever is already in your home rather than pushing a single brand. In Farmers Branch that means a lot of Goodman and Rheem from the 1990s and 2000s, plus newer Lennox and Trane systems in infill construction. We keep common parts for all of these on hand so most repairs don’t wait on a supply house run. More detail on our brands.

What pushes a Farmers Branch job toward the top of any range? Restricted attic access that slows the crew down, undersized ductwork that needs correction before a new system can breathe, and older homes where the electrical panel needs an update to support modern equipment. Whatever the number, the price is written down before we start, and it does not change at the door. That’s The Kingswell Way, and it’s been how Coldharbour operates since Victor Mancini first put the standards in writing. Call (430) 213-5796 for an exact quote.
