Quick answer
Plumber Service TX provides complete residential HVAC service in Dallas–Fort Worth: same-day AC repair, seasonal maintenance, full system installation and replacement (with a lifetime workmanship warranty on qualifying systems), furnaces and heating, ductless mini-splits, thermostats, evaporator coils, air handlers, duct sealing, attic insulation and indoor air quality solutions.
Cooling Is Critical Infrastructure in DFW
North Texas air conditioners routinely run 2,500+ hours a season — double what systems endure in milder climates. Triple-digit August afternoons push equipment to its design limits at the exact moment failures become dangerous, especially for kids, seniors and pets. That’s why we treat summer no-cool calls as true emergencies with same-day dispatch.
The flip side of the workload: maintenance here isn’t optional. A spring tune-up that catches a weak capacitor or low refrigerant charge costs a fraction of the compressor it saves, and keeps efficiency from silently drifting 20–30% above your baseline electric bill.
Honest Diagnostics, Right-Sized Replacements
The dirty secret of HVAC replacement is oversizing: a too-big system short-cycles, dehumidifies poorly and dies young. Before we quote a replacement, we run a load calculation on your actual house — orientation, windows, insulation, duct condition — and match equipment to the number, not to the biggest ticket.
And when a repair genuinely makes more sense than replacing, we say so. Our comparison quotes show repair cost, replacement cost, efficiency savings and warranty coverage side by side so the decision is yours, made with real numbers.
- Lifetime workmanship warranty: available on qualifying new system installations — our installation quality, guaranteed for the life of the system.
- Same-day no-cool response: summer AC failures are prioritized across all DFW dispatch zones.
- Load-calculated sizing: every replacement is sized to your home, not a rule of thumb.
- Whole-system approach: ducts, insulation, airflow and equipment evaluated together — because a great unit on leaky ducts is still a bad system.

Air Conditioning & Heating — Frequently Asked Questions
What HVAC services do you provide in Dallas–Fort Worth?
AC repair and maintenance, AC installation and replacement, furnace and heating service, ductless mini-split systems, thermostats, evaporator coils, air handlers, AC filter programs, duct cleaning and sealing, attic insulation and ventilation, and indoor air quality solutions — across Arlington, Fort Worth, Frisco and Southlake.
What is the AC lifetime warranty?
Qualifying new air conditioning systems installed by Plumber Service TX are eligible for our lifetime workmanship warranty: if our installation labor is ever the cause of a failure, we repair it free for as long as you own the system. Equipment itself remains covered by the manufacturer’s warranty, and full terms are provided in writing before you buy.
How fast can you fix my AC in summer?
No-cool calls are treated as emergencies from June through September. Email service@plumberservicetx.com with URGENT in the subject and dispatch will confirm the fastest same-day window available for your address.
How often should AC be serviced in North Texas?
Twice a year: a cooling tune-up in spring before the heat arrives and a heating check in fall. DFW systems run so many hours that annual-only maintenance leaves capacitors, refrigerant charge and drain lines unchecked through their highest-failure season.
Why is my AC running constantly but the house is still warm?
The most common DFW causes are low refrigerant from a slow leak, a dirty or frozen evaporator coil, leaking attic ductwork losing cooled air, or an undersized/failing compressor. A proper diagnostic pinpoints which — guessing with refrigerant top-offs wastes money.
Should I repair or replace my air conditioner?
A useful rule: multiply the repair cost by the system’s age in years — if it exceeds about $5,000, replacement usually wins. We show you that math with your real numbers, including efficiency savings, rebates and warranty differences, and support either choice.
Do you install ductless mini-splits?
Yes. Mini-splits are ideal for garages, home offices, additions and older homes without ductwork. We size, mount and commission single-zone and multi-zone systems and explain realistic operating costs before you commit.
Does duct sealing really lower cooling bills?
In DFW, ducts typically run through 130°F attics, and the average home leaks 20–30% of its cooled air there. Sealing and insulating ductwork is often the highest-ROI comfort upgrade available — frequently more impactful than replacing the AC unit itself.
