North Texas summers are no joke. Keller bakes through July and August with daytime highs above 100 for weeks straight, and overnight lows that barely drop below 80. Brick veneer two-stories in Hidden Lakes and stucco builds along Marshall Ridge soak that heat into the framing and hold it well past sundown. Once the AC quits, indoor temps climb 10 degrees in under an hour. The expansive clay soil that shifts under most Keller foundations also pulls on outdoor unit pads, knocking lines out of plumb and stressing copper joints. That is a real safety issue for anyone inside, especially older residents and small kids. We answer the phone day and night because riding out a 105-degree afternoon with no cooling is not a plan.
AC problems we fix across Keller
If your system is showing any of these signs, pick up the phone. We have run into every one of these failures hundreds of times and most wrap up in a single visit.
AC blowing warm air
The number one call we get. Three suspects show up most often: a refrigerant leak, a compressor that stopped cycling, or a frozen evaporator coil. We track down the root cause instead of just patching what you feel at the vent. North Texas summers stack 100-degree days on top of high dew points, and that combo loads up evaporator coils fast. Pollen in spring and the dust kicked up off Highway 377 construction zones plug filters in weeks. If warm air is coming out of your vents, we can usually wrap the fix the same afternoon.
Unit will not start
A tripped breaker, a fried capacitor, or a thermostat that lost connection can keep the system from kicking on. Most of these repairs run $150 to $300. It is not a $5,000 project. Newer builds in Marshall Ridge and Estancia have modern panels sized for AC loads. Older homes around Old Town Keller along Bates Street and South Main were rewired in different decades, and some panels trip when a 4-ton condenser pulls startup amps on a 102-degree August afternoon. We meter every part before we quote a price.
Runs nonstop but the house stays warm
The system runs all day but the temperature barely moves. Caked condenser coils, low refrigerant, or a compressor losing pressure are the usual suspects. When Keller hits 105 in late July, a struggling unit cannot keep pace. Plenty of homes in Hidden Lakes and along Bear Creek Parkway were built with builder-grade 13 SEER units that are now 12 to 18 years old and past their service life. We tell you straight whether the unit can be saved or whether replacement is the smarter spend. Need replacement options? See our AC installation page.
Strange noises from the outdoor unit
Grinding points to worn motor bearings. Squealing usually means a belt or blower motor issue. Clicking at startup signals a relay or contactor going bad. Banging suggests a loose part inside the compressor housing. None of these get better on their own. A $200 fix today turns into a $2,000 repair next month if you let it ride. If you hear buzzing or humming that was not there before, call for a diagnosis before the damage spreads.
AC short cycling on and off
The system kicks on, runs for a few minutes, shuts off, then fires right back up. This pattern wears out your compressor and runs your Oncor electric bill through the roof. Common causes: an oversized unit (a frequent issue in newer Estancia patio homes), a clogged filter, low refrigerant, or a failing thermostat. Short cycling beats up electrical parts too. If your system is doing this, treat it as an emergency AC repair. Call before the compressor dies.
Power bill jumped with no clear cause
If your Oncor bill spiked $50 to $100 and nothing else changed in the house, your AC is working harder than it should. A slow refrigerant leak, dirty condenser coils, a weak run capacitor, or duct leaks in your attic could be the source. Keller homes with flex duct in unconditioned attics lose 20 to 30 percent of cooling output through duct leaks alone, and attic temps regularly hit 140 in July. We find the cause and fix it. Most of these repairs pay for themselves within one billing cycle. Yearly AC tune-ups stop most of these problems before they start.
Putting it off only runs the bill up.
Most AC failures get worse with every day you wait. A $200 capacitor swap today blocks a $2,000 compressor failure next month.

Why Keller homeowners call us first
We are not a national franchise. No 1-800 number routing your call to a building in another state. When you reach us, you talk to somebody who knows Keller. We work in Hidden Lakes, Marshall Ridge, Estancia, Old Town Keller, Bear Creek, the area around Keller Town Center, and along Highway 377. If you live anywhere in 76244, 76248, or 76262, we are already nearby. We also cover Watauga, Colleyville, Southlake, and North Richland Hills.
Flat pricing. We quote before we touch a thing. The number we give you is the number you pay. No "diagnostic fee" that conveniently lines up with the repair price. No padding the bill to push you toward a full system swap. If your AC has five solid years left, we say so, even when it means less revenue for us. That is how you build a name in a Keller ISD town where parents talk at the football game and word gets around.
We get it right the first time. If the same issue comes back, we come back and make it right. Our trucks carry the parts that fail most often: capacitors, contactors, fan motors, thermostats. That means most jobs wrap up in a single trip. No ordering a part and asking you to wait until Thursday.
A full AC swap runs $6,000 to $12,000. Before you sign off on one, get a second opinion from a shop that does not pay its techs on commission. Call us at (817) 945-6320 for an honest read.
"Our AC died at 11 PM on a Friday during a July heat dome. They picked up the phone, had a tech at our door by 8 AM Saturday, and wrapped the job for $290. The first shop I called wanted $200 just to come out. These guys quoted on the spot and had cold air running within an hour."

"Another shop quoted us $8,500 for a brand new system. These guys came out, swapped a capacitor for $185, and the unit has run like new for over a year. They saved us thousands."
