We know Keller’s housing stock well. Thousands of homes here were built during the 1990s and 2000s boom, and many still run their original 10 to 12 SEER systems. Those units are now hitting the 20 to 25 year mark at the same time, which means a wave of mid-summer failures across neighborhoods like Hidden Lakes, Marshall Ridge, and the older sections near Bear Creek Park. Our AC Repair team arrives ready to diagnose the exact failure, explain it in plain language, and give you a fixed price in writing before we pick up a tool.

Styles & brands we work with
AC Capacitor Replacement in Keller
AC capacitor replacement in Keller is one of the most common repairs we handle from June through September. A capacitor is the small cylinder inside your outdoor unit that gives the compressor and fan motor the electrical jolt they need to start. Keller’s prolonged triple-digit heat waves push capacitors hard, and when one fails, your AC either won’t start at all or the fan runs while the compressor doesn’t. A typical capacitor replacement in Keller runs $150 to $450, including the part and labor.
Signs a Capacitor Is About to Fail
A capacitor often gives warning before it dies completely. You might hear a humming sound from the outdoor unit but no fan spinning. The AC might struggle to start, or you may notice the compressor short-cycling on and off. During a Keller heat wave, these symptoms usually show up in the late afternoon when the system has been running all day.
How It’s Tested and Replaced
Our technicians test the capacitor’s microfarad rating with a meter before recommending replacement. If it’s reading below spec, we show you the reading and explain what that means. We stock common capacitor sizes for Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard systems, so most Keller repairs are done same-day. The written price covers the new capacitor, installation, and a full system test before we leave.
AC Recharge in Keller
AC recharge in Keller, also called a refrigerant recharge, means topping off the coolant your system needs to produce cold air. When refrigerant levels drop, usually because of a slow leak somewhere in the lines or coils, your AC runs constantly but can’t keep the house cool. In Keller, a refrigerant recharge typically runs $200 to $500, including locating and sealing the leak, recharging to the correct level, and verifying the system is cooling properly again.
R-22 vs. R-410A Systems
Many 1990s and early 2000s homes in Keller were built with R-22 systems. R-22 refrigerant has been phased out of production, which means recharge costs for these older units are higher than for newer R-410A systems. If your R-22 system is leaking, a repair might not make financial sense. We’ll tell you honestly whether a recharge is worth it or whether you should put that money toward a new SEER2-rated system instead.
When a Recharge Is Enough
A recharge works well when the leak is in an accessible spot like a Schrader valve or a visible line fitting. If the leak is inside the evaporator coil or buried in the walls, patching it may be a short-term fix. We’ll find the leak, show you where it is, and give you a written recommendation on repair versus replace before we do anything. No pressure, just the facts and the numbers.

Our technicians are certified to service major brands including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard, and we offer Keller Carrier service among them.

We don’t push one brand over another; we fix what you have and tell you when it’s no longer worth fixing.

AfterCommon AC Repair Problems We See in Keller Homes
- Capacitor failures from extreme heat. Keller’s triple-digit summer runs put enormous strain on capacitors. When the outdoor unit sits in direct sun on a 105-degree afternoon, the capacitor’s internal material degrades faster than in milder climates.
- Uneven cooling in two-story homes. Many Keller homes built in the 1990s and 2000s have conditioned attics with high duct leakage. The upstairs runs 8 to 10 degrees warmer than downstairs, and the AC runs constantly trying to compensate.
- Sweating plenums and rusted drain pans. Tight attic utility closets, common in Hidden Lakes and Marshall Ridge, trap humidity around the air handler. By early June, we regularly find sweating plenums and secondary drain pans already rusting.
- Refrigerant charge issues on aging R-22 systems. Original 10 SEER units from the 1990s and 2000s are reaching end of life all over Keller. Slow refrigerant leaks cause reduced cooling capacity and higher electric bills months before a full failure.

Keller’s enforcement of current IECC energy codes changes the repair conversation. When a repair touches ductwork, insulation, or zoning, the work often needs to meet current code requirements. That means some AC repairs in Keller aren’t just about fixing a failed part. They may involve compliance-oriented upgrades like duct sealing or zoning retrofits, a demand neighboring towns rarely face. We’ll tell you upfront if your repair triggers code work and what that adds to the total.

FAQs About AC Repair in Keller
Most 1990s Keller homes have two separate issues working together: the original ductwork runs through a hot attic with significant leakage, and the single-zone system was sized for the whole house without accounting for how much heat rises. The upstairs loses conditioned air through leaking ducts while gaining heat from the attic, so it can run 8 to 10 degrees warmer than downstairs. Proper duct sealing, zoning retrofits, or a correctly sized replacement system fixes this, and in winter you can rely on our Furnace Repair in Keller for the heating side. Call (817) 632-5499 and we’ll measure the actual temperature difference in your home and give you honest options.
You’ll hear a humming sound from the outdoor unit while the fan isn’t spinning, or the compressor will short-cycle on and off instead of running steadily. Some capacitors bulge visibly at the top before they fail completely. If your AC hesitates to start or makes a clicking sound from the outdoor unit, that’s the capacitor straining. We test capacitors with a meter and show you the exact reading, so you can see the problem yourself before approving the repair. Call (817) 632-5499 and we’ll be there, usually same-day when you’re in Keller.
SEER2 is the updated efficiency testing standard that took effect in 2023. It measures real-world performance under more realistic conditions than the old SEER rating, so a 16 SEER2 unit is roughly equivalent to a 17 SEER old-SEER unit. For Keller homeowners replacing an aging system, SEER2 is the number that determines your actual energy savings and your eligibility for rebates. If your current system is a 10 or 12 SEER original, a 16 SEER2 replacement can cut your cooling bill significantly. We’ll model the savings for your specific home size and ductwork before you commit to anything.
If your R-22 system needs a major repair like a compressor or evaporator coil, replacement is almost always the better financial decision. R-22 refrigerant costs keep climbing because production has been phased out, and a 20-year-old system is running at roughly half the efficiency of a new SEER2 unit. Put $200 to $500 toward an R-22 recharge on a leaking system, and you may be back in the same spot next summer. We’ll give you the repair cost and the replacement cost side by side, in writing, and help you decide without any sales pressure. Call (817) 632-5499 for an honest assessment.
This usually points to a refrigerant charge issue, a failing compressor, or severely undersized ductwork for your home’s heat load. In Keller’s high-humidity summer conditions, a low refrigerant charge means the coil can’t absorb enough heat, so the system runs endlessly without hitting the thermostat set point. Duct leakage in a conditioned attic makes it worse by dumping cooled air into the attic instead of your rooms. We’ll diagnose the exact cause with pressure gauges and airflow measurements, then give you a written price to fix it right.
