HVAC Company in Carrollton, TX
Carrollton homeowners typically pay $150-$700 for HVAC repairs and $3,500-$7,500 for full AC installation, with most service calls completed same-day during business hours. At Coldharbour Heating & Air, we dispatch technicians who understand how Carrollton’s 1970s-1990s housing stock, black gumbo soil, and extreme attic temperatures change what breaks and how to fix it right the first time. Call us at (817) 402-2972 for a free estimate, or read on to see how Carrollton’s specific conditions affect your system.
Why Carrollton Homes Are Different
Carrollton’s residential core went up almost entirely between 1975 and 1995. That means whole subdivisions are crossing the 30-45 year threshold together, and much of the original equipment still runs on R-22 refrigerant. Since the 2020 phase-out, virgin R-22 can no longer be legally produced or imported. A “simple” recharge on an aging system is no longer possible at any price, which pushes many Carrollton homeowners toward full replacement earlier than they expected.
The city’s brick-veneer, slab-on-grade construction sits on expansive black-clay soil that swells and shrinks with moisture. We’ve found cracked underslab duct runs in homes throughout the area, silently dumping conditioned air into the ground. Summer attic temperatures regularly exceed 150°F here, cooking flex duct, duct mastic, and air handler components years faster than manufacturer estimates predict. And Carrollton’s position on the southern edge of the Great Plains means polar fronts can drop temperatures 40°F in under an hour, forcing heat pumps to switch to emergency heat with no warning.
After Winter Storm Uri in February 2021, we saw a pattern: the heat-pump-only systems installed during the 1985-1995 boom often lacked adequate auxiliary heat strips. When outdoor temperatures held below 32°F, those systems simply could not keep up. Many of those same homes are now reaching our replacement queue.
Our Main Carrollton Services
Carrollton homeowners call us most often for cooling repairs in July and heating repairs in January. Here’s what each job looks like in this market.
AC Repair in Carrollton
AC repair in Carrollton means working on systems that have baked in 150°F attics for fifteen to twenty summers straight. We see failed capacitors, pitted contactors, and refrigerant leaks at the evaporator coil, especially on original R-22 systems where the copper has work-hardened over decades of thermal cycling. Our technicians carry capacitors, contactors, and hard-start kits for Rheem, York, Daikin, Bryant, and other major brands on every truck, so most AC Repair in Carrollton jobs finish in a single visit.

Furnace Repair in Carrollton
Furnace repair here often means addressing the aftermath of rapid temperature swings. Igniter failures are common on 1990s-era furnaces that have cycled through thousands of on-off sequences. We also find heat exchanger cracks on high-mileage units, and we replace failed control boards on heat pumps that got overworked during Uri-type events. Every Furnace Repair in Carrollton comes with our written 365-Day Done Right Promise before we leave.

AC Installation in Carrollton
AC installation in Carrollton requires load calculations that account for the real heat gain from those superheated attics, not textbook assumptions. We size systems for the actual envelope, inspect ductwork for black-gumbo damage, and discuss whether a heat pump with proper auxiliary heat makes sense given Uri-level events. A AC Installation in Carrollton job gets a written fixed price, a scheduled install date, and all rebate paperwork handled.

FAQs About HVAC Company in Carrollton
We answer calls with a live person 24 hours a day, and most Carrollton emergency calls receive same-day response during business hours and overnight dispatch for true no-heat or no-cool situations in dangerous temperatures. Call (817) 402-2972 to check current availability.
Most Carrollton HOAs require 24-48 hour advance notice for equipment changes that alter exterior appearance, such as condenser relocation or line-set routing. We handle the paperwork and photo documentation as part of our installation process; repairs that do not change the exterior typically need no HOA involvement.
We can repair any system, but many 1980s Carrollton units run on R-22 refrigerant, which can no longer be legally recharged with new product. We will show you exactly what refrigerant your system uses, explain your repair-versus-replace options, and give you a written price for either path before any work begins.

What Carrollton Customers Say
"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"The repair was done well and quickly. Scheduling over the phone was a little clunky and I got transferred twice, but the tech himself was great and on time."
- Brett Haygood"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
