Dallas summers don't give a struggling AC system much room to recover. Normal highs sit around 95-96°F through July and August with dew points near 70°F, which means a system isn't just cooling the air, it's fighting humidity on top of heat for months at a stretch. In 2023 that pattern hit an extreme: 55 days at or above 100°F for the year, including a 21-day streak from late July into mid-August, and 38 mornings where the low never dropped below 80°F — meaning compressors got no real nighttime recovery before starting the next day's run. A 12- or 15-year-old system that was already working hard in a normal Dallas summer is running on borrowed time once summers look like that.
We replace failing and undersized AC systems, heat pumps, and furnaces across Dallas, sizing every replacement with an actual Manual J load calculation instead of matching the old unit's tonnage by default — a lot of original builder-grade systems were oversized or undersized to begin with. Every system we install meets the SEER2 minimum efficiency standard that took effect in 2023, and if your home qualifies for an Oncor efficiency rebate, we handle that paperwork, including the smart thermostat requirement most of those programs now carry.
Why So Many Dallas AC Systems Are Failing Right Now
Residential AC systems generally last 10 to 15 years, which means systems installed in the early-to-mid 2010s are hitting the end of that window now, right as Dallas summers have gotten more extreme rather than less — 2023 was the 4th-hottest year on record for the area. A system built for an average Dallas summer two decades ago is being asked to survive a much harder one today, and a lot of failures we see aren't sudden — they're a slow decline in a compressor that's been overworked for years finally giving out during the worst possible week to be without cooling.
SEER2: Why You Can't Just Swap In the Old Rating
As of January 2023, Texas falls under the DOE's Southwest region minimum efficiency standard, which requires split-system AC under 45,000 BTU to meet 14.3 SEER2 — a tougher, more realistic testing method than the old SEER rating, so a comparable old SEER number actually performs worse under SEER2 testing. Any system installed before 2023, including a lot of the 13-14 SEER builder-grade equipment common in Dallas subdivisions from the 2000s and 2010s, is now below the legal minimum for new installation. We only install SEER2-compliant systems, sized correctly for your home rather than defaulting to whatever tonnage was there before.
Frequently Asked Questions
Do I need a permit to replace my AC system in Dallas?
Yes. The City of Dallas requires a mechanical permit for full AC system replacement under its building code, including a like-for-like swap at the same system size. We pull the permit and coordinate the required inspection as a standard part of every replacement.
What is SEER2 and why does it matter for my replacement?
SEER2 is the current DOE minimum efficiency standard that took effect in January 2023, requiring most residential split AC systems in Texas to meet 14.3 SEER2. It uses a more realistic testing method than the old SEER rating, meaning an older system's efficiency number doesn't translate directly. Any system installed before 2023 may now be below the legal minimum for new installation, which is relevant if you're comparing quotes against older equipment specs.
Will you just match the size of my old AC system?
No. We run a Manual J load calculation for every replacement rather than defaulting to the old system's tonnage, since a lot of original installations — especially builder-grade systems — were sized off a rough square-footage estimate rather than an actual calculation. Getting the size right affects both comfort and efficiency.
Do you handle Oncor rebate paperwork?
Where a system qualifies, yes. Oncor's residential efficiency programs generally require the new equipment to meet SEER2 minimums and, in most cases, installation of a qualifying smart thermostat. We confirm eligibility and handle the paperwork as part of a qualifying install.
How long does an AC system typically last before it needs replacing?
Most residential AC systems last 10 to 15 years, though Dallas's increasingly extreme summers can shorten that for systems that have been running near-constantly during the hottest stretches. If your system was installed in the early-to-mid 2010s or earlier, it's worth having assessed even if it's still running.
Do you offer a warranty on AC replacement?
Yes, we provide a written warranty covering both the system and the installation labor behind it.
