AfterHVAC Company in Arlington, WA
Coldharbour Heating & Air handles AC repair, furnace repair, and AC installation for Arlington homeowners, with most repair calls completed same day and pricing given in writing before any work starts. Arlington’s housing stock, built mostly during the 1970s through early 1990s suburban boom, means we’re working on aging systems in extreme attic heat rather than new construction, so our trucks carry the parts and duct materials those jobs actually demand. Call us at (817) 402-2972 for a free estimate.
Why Arlington Homes Are Different
Arlington sits in the heart of the Dallas-Fort Worth heat island, where July highs average near 97°F and stretches above 105°F are common. That pushes residential cooling systems to run 14-16 hours daily for months, accelerating wear on compressors, capacitors, and the refrigerant lines snaking through attics that routinely hit 150°F or higher.
The housing tells the rest of the story. Most Arlington homes are 1970s-1990s brick-veneer ranch and two-story tract homes on slab-on-grade foundations laid over expansive Blackland Prairie clay. That clay shrinks and swells dramatically with moisture changes, stressing supply plenum connections and any ductwork routed through or near the slab. The original builder-grade systems, many with centrally located hallway returns and long attic duct runs wrapped in minimal insulation, are now 30-50 years old and failing across entire subdivisions at once.
We see it constantly east of Collins Street and around the Dalworthington Gardens pocket: 1980s systems still running on R-22 refrigerant, flex duct separated at the collar and dumping conditioned air straight into a 155°F attic. The homeowner only knows their bill is inexplicably high. Because Arlington is essentially built out and landlocked between Dallas and Fort Worth, nearly every HVAC job here is a swap or repair on aging equipment, not a fresh install on new construction.
Periodic severe ice storms, most infamously February 2021’s Winter Storm Uri, exposed another local pattern: chronic under-sizing of heating capacity in homes designed around cooling dominance. That event made heat-pump and dual-fuel upgrades a recurring post-freeze priority we still field calls about.
Our Main Arlington Services
Arlington homeowners call us most often for cooling repairs in peak summer and heating repairs during cold snaps, with system replacement becoming increasingly common as the 1980s and 1990s housing stock ages out.
AC Repair in Arlington
AC repair in Arlington means working on systems pushed to their limit by DFW heat island conditions. We replace failed capacitors, recharge refrigerant (topping off the cooling fluid your AC needs to run), and swap compressors that have burned out from overwork. Our trucks stock capacitors, contactors, and refrigerant for the nine major brands we service, so most AC Repair in Arlington calls finish in a single visit. We also hunt for the duct leaks that drive up bills in older subdivisions, using digital testing rather than guesswork.
Furnace Repair in Arlington
Furnace repair here often means addressing systems that sat idle through long cooling seasons, then failed on the first cold night. We replace igniters, clean flame sensors, and repair heat exchangers on gas furnaces from the major manufacturers. After Winter Storm Uri, we’ve also handled more heat-pump defrost board failures and auxiliary heat lockouts than typical northern markets see. Every Furnace Repair in Arlington comes with our written 365-Day Done Right Promise before we leave.
AC Installation in Arlington
AC installation in Arlington is almost always a replacement, not a new construction job. We size systems using Manual J load calculations that account for the actual insulation, window quality, and duct condition of each home, not the original builder’s rule-of-thumb from 1985. That matters because many Arlington homes have had window upgrades or patio enclosures that changed their cooling load. We handle refrigerant line replacement, duct sealing, and pad leveling on the Blackland Prairie clay. AC Installation in Arlington includes a written fixed price, a set install date, and any available rebate paperwork.

What pushes Arlington prices toward the higher end: attic work in 150°F summer heat, refrigerant line sets that need full replacement due to age degradation, and duct sealing or replacement in homes where original flex duct has collapsed. What keeps them lower: straightforward capacitor or igniter swaps on systems we’ve maintained. Either way, you’ll get a written price before any work begins, and that price doesn’t change at your door.

FAQs About HVAC Company in Arlington, WA
Most Arlington repair calls are scheduled same day or next day, with emergency calls for no-heat or no-cool situations prioritized. Our phones are answered by a live person 24 hours a day, 7 days a week, so you’ll never hit a voicemail tree when your system fails on a Saturday night or holiday weekend.
Some Arlington subdivisions, particularly in master-planned communities, require HOA notification for outdoor unit replacement or visible line-set routing. We handle that paperwork as part of our standard process for installation jobs. Permits are pulled when required by Arlington building codes, with no surprise fees added later.
In Arlington’s older tract-home subdivisions, we most often find ductwork separated at flex-duct collars, dumping conditioned air into 150°F attics while the system runs overtime to compensate. A duct-leakage test usually reveals the problem, and sealing or replacing that attic ductwork often cuts cooling runtime by nearly half. Call (817) 402-2972 for a free estimate.

What Arlington 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."
