HVAC Repair and Replacement Cost in Arlington, TX (2026)
Deciding between repairing an aging HVAC system and replacing it outright is one of the biggest home maintenance decisions Arlington homeowners face. Because Arlington runs both cooling and heating hard (blistering summers, occasional hard winter freezes), systems here tend to have shorter practical lifespans than in milder regions. This guide lays out 2026 pricing for both repair and full replacement across the Arlington/DFW market, so you can budget accurately. If you're only dealing with a straightforward AC issue, our AC repair cost guide may be a faster read.

Repair costs for furnaces and full systems
Furnace repairs in Arlington typically run $150-$650, covering common issues like igniter failure, blower motor problems, or a cracked heat exchanger diagnosis. Since Arlington winters are mild, furnaces here see far fewer running hours than AC units, so failures are often tied to age and lack of maintenance rather than heavy wear.
Combined system diagnostics (checking both the furnace and AC on a single failure call, common with shared ductwork or thermostat issues) usually cost $89-$150 for the visit, with repairs quoted separately once the issue is identified.
Full replacement costs in the Arlington market
A straightforward AC-only replacement (3-ton, standard 14-15 SEER2 efficiency, matching coil) runs $5,200-$8,500 installed in the Arlington area as of 2026. Higher-efficiency systems (16-18 SEER2) or larger 4-5 ton units for bigger homes run higher, often $7,500-$11,000.
A full system replacement covering both the AC condenser and a matched gas furnace typically runs $8,500-$14,000 depending on furnace BTU output, ductwork condition, and whether electrical or gas line upgrades are needed.
Heat pump replacements, increasingly popular in North Texas due to mild winters, run $6,500-$11,500 for a full system including the air handler.
Permits and code requirements for replacement
Any HVAC installation or replacement in Arlington requires a mechanical permit through the City of Arlington's Development Services department, submitted via the Arlington Permits online system. Gas furnace installations generally require a separate gas permit, and new electrical circuits for outdoor units require an electrical permit.
Contractors licensed under TDLR's ACR program typically handle these permits directly as part of the installation quote. Ask for the permit number once filed, and confirm final inspection is scheduled before paying the final invoice.
City of Arlington mechanical permit fees for a residential HVAC change-out typically run $75-$150, with an additional $50-$100 if a gas line or new electrical circuit is involved; total permit and inspection fees for a full AC/furnace swap usually land in the $125-$250 range. Most contractors fold this into the total quote rather than billing it as a separate line item, so ask to see it broken out.
Inspections are usually scheduled within 1-3 business days of the permit being filed through the Arlington Permits online portal, and a licensed contractor can typically get a rough-in and final inspection completed without the homeowner needing to be present, though it's worth confirming your installer will notify you once the final inspection has passed.
How to decide between repair and replacement
As a rule of thumb, if your system is under 8 years old, repair almost always makes sense. Between 8-15 years, weigh the repair cost against roughly 50% of a new system's price, factoring in your unit's refrigerant type and overall condition. Past 15 years, especially with R-22 refrigerant, replacement is usually more cost-effective over a 3-5 year horizon.
Before committing to either path, get at least two written quotes from licensed Arlington contractors. Our guide to vetting HVAC companies covers the questions to ask, and you can get matched with local pros here. You can also browse the Arlington HVAC hub for neighborhood-specific notes.
Financing and efficiency upgrade considerations
Many Arlington HVAC contractors offer financing plans for full replacements, typically 0-9.9% APR over 12-60 months depending on credit approval, which can make a $10,000 system replacement manageable as a monthly payment rather than a lump sum.
Upgrading to a higher-efficiency system (16 SEER2 or above) costs more upfront but reduces summer electric bills meaningfully in a climate where the AC can run 8-12 hours a day for months. Oncor, the local electric utility serving most of Arlington, has periodically offered efficiency rebates, so ask your contractor whether current rebate programs apply to your installation.
Oncor, which serves most of Arlington and the surrounding DFW area, has periodically run efficiency incentive programs (sometimes through its Take A Load Off Texas initiative) offering rebates for qualifying high-SEER2 AC and heat pump installations; rebate amounts and availability change from year to year, so ask your contractor for the current program details and confirm the rebate paperwork is filed before or at installation, since many programs require pre-approval.
Ductwork and attic conditions affecting cost
Arlington's attic-mounted systems face extreme summer attic temperatures, sometimes exceeding 140°F, which accelerates wear on ductwork insulation and can push a replacement job toward the higher end of pricing if ducts need resealing or re-insulating at the same time.
Homes in Viridian and other newer developments generally have well-insulated, code-current ductwork, keeping replacement costs closer to equipment-only pricing, while older homes near Downtown/UTA or East Arlington more often need duct work bundled into the replacement quote.
Because most Arlington homes built from the 1970s through 2000s place the air handler in the attic rather than a closet or basement, summer duct losses are a real cost factor: uninsulated or poorly sealed supply runs sitting in 130-150°F attic air can lose 15-25% of cooling capacity before it ever reaches a register, which is why some replacement quotes include duct sealing, added insulation wrap, or a return-air upgrade rather than a straight equipment swap.
After a significant North Texas hailstorm (DFW sees several hail events most years, typically March through June), it's common for condenser coil fins and cabinet housings to take cosmetic or functional damage; if you're getting a replacement quote following storm damage, ask your contractor to document the damage clearly for your homeowner's insurance claim, and be wary of storm-chasing companies that show up door-to-door immediately after a hail event with today-only pricing.

Working with a licensed local installer
A reputable installer will walk you through the full scope in writing before starting demolition of your old unit, including disposal of old refrigerant per EPA rules and confirmation of the mechanical permit number filed with the City of Arlington. Start comparing quotes through the Arlington HVAC hub or get matched with local contractors.
Arlington's building codes follow the 2021 International Mechanical Code, which contractors must reference for equipment clearances, condensate drainage, and combustion air requirements on any new furnace install, so confirm your installer is working from the current adopted code version.
Plan for a one-day installation on most single-family homes, though full duct rework or gas line rerouting can extend the job to two days.
Confirm the installer's TDLR ACR license class matches your job: Class A licenses cover unlimited tonnage, while Class B licenses are capped at smaller residential systems (typically under 25 tons combined). You can verify any contractor's license number, class, and status for free through TDLR's online license search before signing anything.

Common questions
How long do HVAC systems typically last in Arlington, TX?
AC systems typically last 12-15 years in Arlington due to heavy summer usage, while furnaces, used far less, often last 15-20 years.
Do I need a permit to replace my furnace in Arlington?
Yes, replacing a furnace requires a mechanical permit through the City of Arlington, and gas furnaces typically require a separate gas permit as well.
Is a heat pump a good choice for Arlington's climate?
Yes, heat pumps work well in Arlington's mild winters and hot summers, often providing efficient heating and cooling from one system, though supplemental heat strips help during rare hard freezes.
What size AC unit do I need for a typical Arlington home?
Most 1,800-2,400 sq ft Arlington homes use a 3 to 3.5 ton system, but proper sizing depends on insulation, window exposure, and ductwork; a Manual J load calculation from your contractor is the accurate way to confirm.
How much does it cost to replace ductwork in an older Arlington home?
Partial ductwork replacement typically runs $1,500-$4,000, while a full duct system replacement in a mid-size home can run $4,000-$8,000 depending on attic access and duct length.
