AfterFast, Reliable AC Installation Across Arlington
A new AC installation in Arlington typically costs $3,500-$7,500 for a standard split system, and most jobs are completed in one to two days once equipment is on hand. We’re Coldharbour Heating & Air, and our AC Installation team has been replacing aging systems in Arlington’s 1970s-through-1990s subdivisions since 2003. Our Dallas-Fort Worth office dispatches crews directly to Arlington homes, and a live person answers our phones at (817) 402-2972 every hour of every day. We know the difference between a quick swap and a proper installation because we’ve seen what happens when builder-grade equipment, sized by guesswork rather than math, gets replaced with more of the same.
Why Coldharbour Heating & Air Is Arlington’s Preferred AC Installation Company
Arlington is built out. Landlocked between Dallas and Fort Worth, the city stopped growing outward decades ago. That means nearly every AC installation we perform here is a replacement in a 30- to 50-year-old tract home, not a new construction job. We understand the local housing stock: brick-veneer ranch and two-story homes on slab-on-grade foundations over Blackland Prairie clay, with attics that hit 150°F in July and ductwork that was barely adequate when it was new.
Our technicians are background-checked, uniformed, and trained on nine major brands including Trane, Lennox, Goodman, and Rheem. Before any work begins, we hand you a written price that does not change at the door. Every repair carries our 365-Day Done Right Promise in writing: if it fails within a year, we come back and fix it at no charge. That’s The Kingswell Way, and it’s how we’ve operated since Victor Mancini founded Coldharbour in 2003.
Homeowners in neighborhoods east of Collins Street and around the Dalworthington Gardens pocket call us because we’ve handled the specific failures those zip codes produce: R-22 systems still limping along, flex duct separated at the collar and dumping conditioned air into 155°F attics, and utility bills that climb every summer without explanation. We don’t just swap boxes. We fix the system that surrounds them.
Heat Pump Installation in Arlington
Heat Pump Installation in Arlington has become increasingly common since Winter Storm Uri in February 2021 exposed how many local homes were built around cooling dominance with chronically undersized heating capacity. A heat pump is an electric system that both heats and cools by moving thermal energy between your home and the outside air, and modern cold-climate models now handle Arlington’s occasional single-digit nights without the backup resistance heat that older versions required.
Because Arlington’s summer cooling loads are among the highest per-capita in the country, with systems running 14-16 hours daily through July and August, the efficiency gains of a properly sized heat pump are substantial. Most Arlington homeowners considering this option are replacing both an aging AC and a gas furnace in a single project. The installed cost typically falls in the $3,500-$7,500 range, though final pricing depends on whether your existing ductwork can handle the airflow requirements of a heat pump’s larger indoor coil.
When a Heat Pump Makes Sense
If your furnace and AC are both past 15 years, a heat pump replaces both with one outdoor unit and one indoor air handler. After Uri, many Arlington homeowners in subdivisions near Matlock Road and Green Oaks Boulevard chose this path to eliminate gas-heat dependency entirely. We perform a full Manual J load calculation before specifying tonnage, because an oversized heat pump short-cycles in cooling mode and an undersized one cannot keep up on the coldest nights.
Dual-Fuel Options for Older Homes
Some Arlington homes with marginal ductwork or very high heat loss benefit from a dual-fuel setup: the heat pump handles cooling and mild heating, while a gas furnace takes over below 35°F. This preserves your existing gas line and can reduce winter peak-demand charges. We size each component separately rather than defaulting to the existing furnace capacity, which was often selected by rule of thumb in the 1980s.
Ductless Mini Split Installation in Arlington
Ductless Mini Split Installation in Arlington solves problems that central ductwork cannot, particularly in the patio conversions, garage workshops, and second-story additions common in the city’s post-1990 remodeling market. A mini split pairs a compact outdoor compressor with one or more indoor wall or ceiling units, connected by a small refrigerant line set that requires only a 3-inch penetration. No ducts. No attic runs. No fighting the static pressure problems that plague Arlington’s original builder-grade systems.
We also install mini splits as whole-home solutions for Arlington’s smaller ranch homes, especially in the Dalworthington Gardens area and near Interlochen, where homeowners want zoned comfort without tearing open walls to retrofit ductwork. Pricing runs $3,500-$7,500 depending on the number of indoor zones and the required BTU capacity. Each indoor unit operates independently, so you cool only the rooms you’re using.
Solving the Hot Upstairs Problem
Arlington’s two-story tract homes were built with centrally located hallway returns and long flex-duct runs that starve second-floor bedrooms of airflow. Rather than replace a perfectly good downstairs system, many homeowners add a mini split upstairs. We mount the indoor unit high on a hallway wall or in the master bedroom, and the outdoor unit sits on a pad beside the existing condenser. The upstairs finally holds setpoint. The downstairs system stops running 18 hours a day trying to compensate.
Garage and Workshop Cooling
Arlington’s summers make unconditioned garages unusable for anything but parking. A single-zone mini split keeps a two-car garage at 78°F for about the same operating cost as trying to extend your central ductwork, which is rarely designed for the additional load and often violates code for return-air pathways. We see this request regularly from homeowners in southwest Arlington near Sublett Road who’ve converted garage space to home gyms or woodworking shops.
Trusted Brands We Service in Arlington
Our technicians carry training certifications for Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Arlington installations, we maintain relationships with regional distributors in the Dallas-Fort Worth metroplex, which means faster parts availability when a condenser coil or control board is needed under warranty. We do not push one brand over another. The right equipment depends on your home’s ductwork, your electrical service, and your comfort priorities. We stock common repair parts for Trane and Lennox systems locally, and our Goodman and Rheem supply lines typically deliver next-day to our Arlington jobs. Every system we install is registered for full manufacturer warranty coverage before we leave the job site, because we’ve seen too many Arlington homeowners stuck with a failed compressor and no parts coverage because the original builder never filed the paperwork.
Common AC Installation Problems We See in Arlington Homes
- Wrong tonnage from rule-of-thumb sizing. The original builder installed a 3-ton system because the house was “about 1,500 square feet.” That ignores Arlington’s 97°F July average, the heat island effect, and the solar gain from west-facing brick veneer. We perform a Manual J load calculation on every replacement. The correct size is often different.
- Unregistered manufacturer warranties. We regularly find Carrier, Trane, and Lennox systems in Arlington’s 1980s subdivisions that were never registered by the builder or first owner. When the condenser coil fails at year eight, the homeowner has no parts coverage. We register every new system before we leave.
- Attic ductwork dumping conditioned air. Flex duct separated at the collar is invisible from below. The homeowner only knows their bill is high and the house never cools. We pressure-test ductwork on every installation and seal or replace what leaks.
- Static pressure from long, undersized runs. Arlington’s hallway-return designs force air through 50 feet of flex duct wrapped in R-4 insulation. The blower motor runs at high amp draw, the evaporator ices, and the compressor short-cycles. We measure static pressure and redesign the duct layout when needed.
Pricing for AC Installation in Arlington, TX
Most standard split-system AC installations in Arlington run $3,500-$7,500, including equipment, labor, refrigerant, and basic electrical connections.

FAQs About AC Installation in Arlington
Yes. Arlington’s builder-grade systems from that era were almost always sized by rule of thumb, not by actual heat gain calculation. A proper Manual J load calculation accounts for your home’s insulation, window efficiency, duct leakage, and the 14-16 hour daily runtime that Arlington summers demand. Without it, you’re likely to get the wrong tonnage again. Call (817) 402-2972 and we’ll perform the calculation as part of your free estimate.
The equipment is rarely the problem. In Arlington’s two-story tract homes, the issue is almost always ductwork: long flex-duct runs with minimal insulation, separated collars dumping air into 150°F attics, and centrally located hallway returns that cannot pull enough hot air from upstairs bedrooms. We measure duct leakage and static pressure on every installation. Often the fix is sealing and rebalancing the existing ductwork, not buying a larger unit.
SEER2 is the updated efficiency rating that took effect in 2023, tested under more realistic conditions that better reflect Arlington’s extreme heat and humidity. A 16 SEER2 unit performs more efficiently in actual Arlington summer conditions than an older 16 SEER unit would have on paper. For a system running 14-16 hours daily through July and August, the operating cost difference is measurable. We specify SEER2 equipment on all new installations.
It depends on your home’s heating load and your comfort with gas dependency. Since Winter Storm Uri, many Arlington homeowners have chosen heat pumps to eliminate reliance on gas lines that can fail in extreme cold. Modern cold-climate heat pumps handle Arlington’s occasional single-digit nights, and the dual-fuel option preserves gas backup if you prefer it. We model both scenarios with your actual load calculation and utility rates so you can compare operating costs before deciding.
Most replacements in Arlington’s slab-on-grade ranch and two-story homes are completed in one full day, or two days if extensive ductwork modification is needed. The slab foundation means no crawl space to work in, which simplifies refrigerant line routing. Equipment availability is typically the longest variable; once your system is on-site, our crew is in and out in a day for a standard swap, or two days if we’re also sealing ductwork and rebalancing airflow.
