AfterFast, Reliable AC Repair Across Keller
When your AC quits in a Keller July, you need a straight answer on what it costs, who is coming, and whether it can be fixed today. Most AC Repair calls we run in Keller land between $150 and $650, with capacitor and contactor replacements on the lower end and compressor or refrigerant work on the higher end. We are Dalton Heating & Air, a Garrison Partners company held to The Garrison Standard since 2003, and we answer our phones with a live person 24/7. Call (361) 306-9515 and you will get a written price before any work starts, a written one-year guarantee on the repair, and a uniformed, background-checked technician who shows up inside the stated window.
Why Dalton Heating & Air Is Keller’s Preferred AC Repair Company
Keller homeowners call us after they have been burned by no-shows and door-price changes, and what they get instead is a crew that puts the price in writing before touching a single component. Every repair we perform in Keller carries the 365-Day Done Right Promise: if the work does not hold for a full year, we return at no charge. That is not an upgrade. It is the standard on every job we run, from a capacitor swap on a townhome off Bourland Road to a full condenser rebuild near Keller High School.
Our technicians are factory-trained to service nine major residential brands, so we are not guessing at your Trane or Rheem. We arrive inside the window we give you, we leave the site clean, and Marco Benitez holds every tech to The Garrison Code on every call. The written guarantee is part of that code, not a line item. If the repair fails inside the warranty period, you get a free second visit. Period.
Emergency AC Repair in Keller
Emergency AC Repair in Keller means a system that has stopped cooling during a run of 100°F-plus afternoons, when the indoor temperature climbs past 85°F and the condenser outside is running nonstop or not running at all. A Keller homeowner needs this when the thermostat is set to 74°F and the house will not drop below 82°F by midday, or when the outdoor unit is making a hard buzzing sound and the fan is not spinning. Emergency calls in Keller run $150 to $650 depending on what failed, and we respond same-day when you call (361) 306-9515.
Capacitor Failures During Heat Waves
The dual-run capacitor takes the worst of Keller’s July and August stretch. When the condenser runs nearly nonstop for ten straight afternoons, the capacitor overheats, swells, and drops out of tolerance. The compressor will not start, or it short-cycles and trips the breaker. A capacitor replacement typically runs $150 to $350 including the part and labor, and we carry common values on the truck so the repair happens on the first visit.
Condenser and Contactor Failures
The contactor is the switch that tells the compressor and fan to turn on. High current draw during a Keller heat wave arcs the contact points until they pit or weld. We see this on units along North Tarrant Parkway where homes are exposed to full afternoon sun. Replacing a contactor is a same-day job and falls inside the $150 to $650 repair band.
AC Not Blowing Cold Air in Keller
AC Not Blowing Cold Air in Keller usually comes down to one of three things: a refrigerant charge that has drifted low, a failed capacitor that prevents the compressor from starting, or a blower motor that has stopped moving air across the coil. Homeowners in the 76248 and 76262 zip codes call us when the vents are blowing lukewarm air and the thermostat will not satisfy. A diagnostic and repair on a no-cooling call in Keller runs $150 to $650, and we never start the work until you have seen the written price.
Refrigerant Recharge and Leak Checks
Refrigerant recharge, which is topping off the cooling fluid your system needs to reach set temperature, is a common Keller repair when a slow leak has developed at a braze joint or service valve. The thermal expansion and contraction between 100°F summer days and 20°F winter nights stresses those connections. We do not just add refrigerant and leave. We find the leak, repair it, and then verify the charge by superheat and subcooling readings.
Compressor Diagnosis
When the compressor itself has failed, the repair-versus-replace math gets real. A hard-start kit may buy time on an older unit, but a burned-out compressor on a 12-year-old system often means replacement is the honest answer. We give you the repair price and the replacement price side by side, in writing, so you can decide with numbers instead of a sales pitch.
Trusted Brands We Service in Keller
We service the brands already installed in Keller homes: Trane, Lennox, Goodman, and Rheem are the most common we see, and our techs are factory-trained on all of them. That training matters when a Goodman condenser from a 2015 build off Keller-Smithfield Road needs a specific contactor, or when a Trane heat pump needs a control board that is not a universal part. We stock common repair parts for Keller customers on our trucks, so the fix happens on the first trip more often than not. If the part is not local, we order it same-day and schedule the return visit inside the window we give you.
Common AC Repair Problems We See in Keller Homes
- Capacitor failures in the July-August heat run. Consecutive 100°F-plus afternoons push the condenser start windings hard, and the capacitor is the first part to give. It swells, leaks, or drops out of tolerance, and the compressor will not start.
- Refrigerant charge drift from North Texas temperature swings. A pad that bakes at 102°F in July and drops near 20°F in January works the solder joints and service valves. A slow leak shows up as ice on the evaporator coil and a compressor that short-cycles.
- Undersized replacements from prior contractors who skipped the load calculation. We see Keller homes where a previous company swapped in the same tonnage without running a Manual J. The system cannot hold setpoint on the hottest days, and the compressor runs too long and dies early.
- Blower motor and relay failures in older split systems. Homes built in the 1990s and early 2000s around Keller’s established neighborhoods often have original air handlers. The blower motor bearings wear, the relay sticks, and airflow drops until the coil freezes.

If the compressor has failed on a 12-year-old unit and the replacement quote hits the $3,500 to $7,500 range, we will show you both numbers side by side. The estimate is free.

FAQs About AC Repair in Keller
Repair it if the system is under ten years old and the failed part is a capacitor, contactor, blower motor, or a small refrigerant leak, which puts most Keller repairs in the $150 to $650 range. Replace it if the compressor has failed on a unit past twelve years old. Keller’s two-season climate matters here. The same condenser that cools your house in August is your heat pump in January, so the replacement conversation has to account for the heating load, not just the cooling load. We will give you both prices in writing and let the numbers decide. Call (361) 306-9515 for a free estimate.
Most AC repairs in Keller run $150 to $650. A capacitor replacement typically lands at $150 to $350. Compressor work, blower motor replacement, or a refrigerant leak repair can reach the top of that range. Every quote is in writing before we start, and the repair is guaranteed in writing for a full year. If it fails in that year, we return at no charge.
Because that is when Keller’s condenser runs almost nonstop. Ten consecutive afternoons above 100°F means the compressor, capacitor, and contactor never cool down, and the start windings take the worst of it. The capacitor swells and drops out of tolerance, the contactor points arc and pit, and the system quits on the hottest day of the year. We carry those parts on the truck for Keller calls specifically because we know the pattern.
Yes. A Manual J load calculation measures your home’s actual cooling and heating demand: square footage, window orientation, insulation, and the west-facing exposure common on Bear Creek Parkway and Keller-Smithfield Road builds. Contractors who skip it and swap in the same tonnage leave Keller homes with a system that cannot hold setpoint in August and shortens compressor life. When we quote a replacement, the load calculation is part of the job, not an upgrade.
SEER2 is the updated efficiency rating for cooling output per watt of electricity, and yes, it shows up on your bill. A 16 SEER2 system uses measurably less power than a 10 SEER2 unit from 2010, especially during Keller’s July and August run. The tradeoff is upfront cost versus monthly savings, and we will show you the payback math on any quote. Call (361) 306-9515 and we will walk you through it.
