Quick answer
Plumber Service TX installs and replaces complete air conditioning systems across Dallas–Fort Worth. Every replacement starts with a Manual J load calculation — not a rule of thumb — so the system matches your home’s real needs. Installation follows manufacturer specification (which is what keeps equipment warranties valid), and qualifying systems carry our lifetime workmanship warranty.
The Sizing Trap: Why ‘Bigger’ Is the Most Expensive Mistake
The most common defect in DFW’s installed AC base isn’t cheap equipment — it’s oversizing. An oversized system cools the thermostat quickly and shuts off before it dehumidifies the air, so the house reads 74° but feels clammy; the constant starting and stopping (short-cycling) is also the hardest duty pattern on a compressor. Undersizing has the opposite failure: a system that runs forever and loses ground at 4 PM in August.
The fix is boring and mathematical: a Manual J load calculation using your home’s actual envelope — square footage, orientation, window area and type, insulation levels, duct condition, infiltration. It takes us an hour and determines a 15-year outcome. No system leaves our quote stage sized by ‘what was there before’ or square-footage folklore.
Installation Quality Is the Product — Equipment Is Just the Box
Industry studies keep finding the same thing: a mid-tier system installed excellently outperforms a premium system installed carelessly. The gap lives in details invisible at handoff:
- Refrigerant charge weighed and verified: not ‘beer-can cold’ — charge accuracy within a few percent is worth double-digit efficiency.
- Airflow commissioned: static pressure measured, blower configured to the duct system’s reality, registers balanced.
- Line sets handled properly: correct sizing, brazed with nitrogen purge, evacuated to deep vacuum verified by gauge — the difference between a 15-year refrigerant circuit and acid contamination.
- Condensate done right: primary and secondary drains, float switches, and pan placement that protects the ceiling under attic installs.
- Electrical to spec: correct breaker and wire sizing, surge consideration, and a disconnect that will pass inspection.
- Permit and inspection: pulled with your city, inspected, documented — required, and routinely skipped by low-bid installers.
Honest Guidance on Efficiency Tiers and the Lifetime Warranty
SEER2 ratings sell brochures, but the right efficiency tier depends on your usage, how long you’ll own the home, and duct condition — a 17-SEER2 system on leaking ducts performs like a 13. We quote good/better/best with real operating-cost math for DFW’s roughly 2,500 cooling hours, and we’ll tell you plainly when the duct sealing matters more than the next equipment tier. Qualifying systems include our lifetime workmanship warranty: if our installation labor ever causes a failure, we fix it free for as long as you own the system.

AC Installation & Replacement — Frequently Asked Questions
How much does a new AC system cost in Dallas–Fort Worth?
It varies with tonnage, efficiency tier, whether the furnace/air handler is replaced together, and duct condition. We quote good/better/best options flat-rate in writing after a load calculation and home evaluation — never a price over the phone for equipment we haven’t sized.
How long does AC installation take?
Most complete residential replacements finish in one day — out with the old system in the morning, commissioned and cooling by evening. Complex jobs (duct modifications, relocations) can run two days; the quote states the expectation.
What is a load calculation and why does it matter?
A Manual J calculation computes your home’s actual heat gain using envelope details — windows, insulation, orientation, ducts — to size the system correctly. Oversized units short-cycle and dehumidify poorly; undersized ones can’t keep up. It’s the single strongest predictor of long-term satisfaction with a new system.
What does the lifetime workmanship warranty cover?
On qualifying new systems: if a failure is caused by our installation labor — brazing, wiring, drainage, mounting, commissioning — we repair it at no cost for as long as you own the system. Manufacturer warranties cover the equipment itself. Complete written terms accompany every eligible quote.
Should I replace the indoor and outdoor units together?
Usually yes. Coils and condensers are engineered as matched pairs; mixing a new condenser with an old coil sacrifices efficiency and often voids the new unit’s warranty. If the indoor unit is genuinely young and compatible, we’ll say so — matched-system pressure sales aren’t our style.
What SEER2 rating should I buy for a Texas home?
Minimum code is the floor, not the answer. With DFW’s long cooling season, mid-tier efficiency (roughly 15.2–17 SEER2) usually hits the payback sweet spot; ultra-high tiers make sense for large usage or long ownership horizons. We show the operating-cost math per tier so it’s your decision with real numbers.
Do you haul away the old system?
Yes — removal, refrigerant recovery (an EPA legal requirement), and disposal of the old equipment are included in every replacement quote, along with the permit and city inspection.
Can I finance a new AC system?
Yes, financing options are available on system replacements. Mention it in your email to service@plumberservicetx.com and the quote will include payment options alongside the cash price.
