How heating and AC repair works in Arlington
Quick answer: most AC and furnace repairs in Arlington land between $150 and $600 including the service call. A full AC changeout runs $5,000 to $12,000 or more; a furnace replacement runs $3,500 to $8,000.
Arlington sits between Dallas and Fort Worth with a deep stock of mid-century and 1980s homes, and the HVAC story here is usually about the ducts as much as the equipment. Original ductwork in these homes is often leaky, undersized, or both. Before pricing a new system, find out whether the ducts are the real problem.
When the system quits on the hottest August afternoon or the coldest January night, you need a tech today, not next week. We do not list or refer contractors yet. Until our vetted Arlington directory launches, use the three checks below on whichever licensed shop you call, and compare the quote against the DFW ranges further down before you approve it.

Hiring an HVAC contractor in Texas: what to check
Check the TDLR license.
Every Texas HVAC contractor must hold a current license from the Texas Department of Licensing and Regulation. Ask for the license number and verify it on the TDLR website before anyone touches your system.
Get it in writing.
A real quote lists the equipment model numbers, parts and labor separately, the permit, and the warranty terms. Verbal estimates and same-day pressure tactics are red flags.
Compare at least two quotes.
Prices vary widely between shops. Two or three written quotes tell you what the market rate is for your job and expose outliers in either direction.

Common questions
How much does AC repair cost in Arlington?
In Arlington, most common AC repairs run $150 to $600: capacitors, contactors, and clogged condensate drains sit at the low end, while blower motors and refrigerant leak repairs cost more. Compressor replacement runs $1,200 to $2,500 or more. Always get the quote in writing with parts and labor itemized.
My AC is running but not cooling. What is wrong?
The most common causes are a dirty air filter, a frozen evaporator coil, low refrigerant from a leak, or a failed capacitor. Start by replacing the filter and making sure the outdoor unit is clear of debris. If it still does not cool, call a licensed tech: running a system low on refrigerant can damage the compressor.
How long do AC units last in Texas?
12 to 15 years with regular maintenance is typical in North Texas, where systems work hard for much of the year. Units past that range are living on borrowed time: replacement parts get scarcer and efficiency keeps dropping.
Should I repair or replace my AC?
Use the $5,000 rule: multiply the repair cost by the unit's age. If the result exceeds $5,000, replacement usually wins. Also weigh efficiency: a new 16+ SEER2 system can cut cooling energy use substantially compared to a 10-SEER unit from the 2000s. Read our repair vs. replace guide for the full walkthrough.
Do I need a permit for an AC replacement in Texas?
Most DFW cities require a mechanical permit for a full system changeout, though simple repairs do not need one. A reputable contractor pulls the permit as part of the job and includes it in the quote. Confirm this before you sign.
How fast can I get emergency AC repair?
Many DFW shops offer same-day appointments during summer, and some run emergency lines for nights and weekends. Expect a trip charge or after-hours fee, and ask for the amount before the truck rolls. We do not refer contractors yet; whoever you call, confirm their TDLR license number and get the fee in writing by text or email before agreeing to the visit.
How much does furnace repair cost in Arlington?
Most furnace repairs in Arlington run $150 to $600: flame sensors, ignitors, and capacitors at the low end, blower motors higher. Full furnace replacement typically runs $3,500 to $8,000. Get the failed part named in the written quote, and ask whether it is still under warranty.
Do heat pumps work through winter in Arlington?
Yes. North Texas winters are mild enough that heat pumps handle most of the season efficiently. When temperatures drop into the 30s, auxiliary heat strips take over and heating bills rise. Keep the outdoor unit clear of leaves and debris, and schedule a fall tune-up before the first cold snap.
How do I know if my ducts are the problem?
Classic signs: some rooms never cool, high summer bills despite a newer unit, or visible damage in the attic. Arlington's stock of mid-century and 1980s homes makes duct issues the first thing to rule out before replacing equipment.
Are mid-century Arlington homes harder to cool?
They can be: less insulation, original ductwork, and single-pane windows add load. An energy audit or duct inspection usually finds the cheapest fixes before you spend on equipment.
