Fast, Reliable AC Repair Across Keller

AC repair in Keller typically runs $150-$650, and our technicians are usually on-site the same day you call.

Call (817) 402-2972

When your upstairs zone quits at 3 p.m. on a 102°F July afternoon, you don’t want a dispatcher in another state. Our Dallas-Fort Worth office coordinates scheduling for Keller, which means crews know the area, know the housing stock, and know that a “quick recharge” on a 1998 R-22 system in Bloomfield often means walking the homeowner through real options. Call (817) 402-2972 any time, day or night. A live person answers, and we’ll give you a firm arrival window before we hang up.

Why Coldharbour Heating & Air Is Keller’s Preferred AC Repair Company

Keller homeowners call us because we’ve been the local, independently operated face of the Kingswell Guarantee since 2003. That means four written promises on every job: a price before the work starts, a firm arrival window, a clean job site, and our 365-Day Done Right Promise. If a repair fails inside a full year, we come back and correct it at no charge. The guarantee is written down before the technician leaves, not offered as a verbal afterthought.

Our technicians are background-checked, uniformed, and trained on nine major residential HVAC brands including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Whatever system is in your home, the person who shows up can work on it. We don’t subcontract to random crews or send a sales rep with a clipboard.

Dispatch is coordinated from our Dallas-Fort Worth office, but the crews serving Keller live and work in the area. They know that a service call off Keller-Smithfield Road during rush hour needs a different buffer than one near Bear Creek Parkway on a Saturday morning. That local routing knowledge translates to on-time arrivals, which is why we can promise a window and stick to it.

AC Recharge in Keller

AC Recharge in Keller most often means adding refrigerant to a system that’s lost charge due to a slow leak, corrosion at the Schrader valves, or age-related permeation through the copper lines. Because so many Keller homes still run original R-22 equipment installed between 1993 and 2008, a recharge request sometimes turns into a larger conversation about refrigerant availability and system replacement timing. A standard recharge in Keller runs $150-$650, with the final price depending on how many pounds your system needs and whether we need to locate and seal a leak.

When a Recharge Makes Sense

If your system is under ten years old and uses R-410A refrigerant, a recharge plus leak repair is usually the right call. We’ll pressure-test the lines, seal the leak, pull a vacuum to remove moisture, and charge the system to factory spec. You’ll get a written price before we start, and the work is covered by our 365-Day Done Right Promise.

When R-22 Changes the Math

R-22 hasn’t been manufactured since 2020, and reclaimed supplies are increasingly expensive and inconsistent. If your Keller home still has its original R-22 system, we’ll give you honest numbers: the recharge cost today, the likelihood of future leaks on a 20-plus-year-old unit, and what a replacement system would run. No pressure, just the facts written down so you can decide.

Emergency AC Repair in Keller

Emergency AC Repair in Keller means your system has failed completely when outdoor temperatures are in the high 90s or above, creating a genuine health risk for children, elderly family members, or anyone with respiratory conditions. We treat these calls with priority routing, and our phone is answered by a live person 24 hours a day, 7 days a week. Emergency repair pricing in Keller follows our standard range of $150-$650; we do not charge overtime premiums for after-hours or weekend calls.

What Counts as an Emergency

Total compressor failure on a 100°F day, a blower motor that won’t start leaving you with zero airflow, or a refrigerant leak that’s dropped your indoor temperature past safe levels. We’ll ask a few questions when you call to confirm priority status and make sure our technician brings the right parts.

What Happens When We Arrive

The technician diagnoses the failure, hands you a written price, and explains your options before touching a tool. If the system can be repaired safely and effectively, we’ll do it. If the failure reveals that replacement is the smarter long-term choice, we’ll show you why and give you that price in writing too. Either way, you decide. No work happens without your clear go-ahead.

Trusted Brands We Service in Keller

Our trucks carry common capacitors, contactors, blower motors, and refrigerant for Trane, Lennox, Goodman, and Rheem systems, plus the other five brands in our training portfolio. That matters in Keller because a Monday afternoon failure shouldn’t mean waiting until Thursday for a parts order. For less common components, our Dallas-Fort Worth warehouse typically has next-morning availability, and we’ll tell you honestly if a same-day finish isn’t possible rather than stringing you along.

Common AC Repair Problems We See in Keller Homes

• Plenum separation from attic air handlers. On a Bloomfield two-story off Keller-Smithfield Road we chased a two-year-old “upstairs is always hot” complaint that two prior tune-ups had never fixed. The upper air handler’s gauges looked fine, but the supply plenum had separated from the unit after two decades of black-clay slab movement, dumping roughly 30% of conditioned air into the attic. We resealed the plenum, re-balanced the flex-duct runs, verified refrigerant charge on the Carrier condenser, and the second floor finally held temperature without touching the equipment.
• R-22 systems that can’t be topped off affordably. Keller’s housing stock peaked between 1993 and 2008, so most homes here are still on their original R-22 systems and almost all of them run two units. A whole-neighborhood replacement wave is hitting dual-zone houses at once, which is not the mixed-vintage, single-system story in closer-in Tarrant County suburbs. When refrigerant is low on a 25-year-old condenser, we walk homeowners through the real math on recharge cost versus replacement.
• Capacitor and blower motor failures during peak heat. Summers routinely push 100°F+ for weeks at a time, placing maximum stress on aging dual systems simultaneously. A weak capacitor on a 1999 Goodman condenser often fails right when you need it most, and the resulting locked rotor can take out the compressor if the homeowner keeps cycling the system.
• Dual-zone imbalance that new equipment won’t fix alone. Keller’s large, two-story brick homes almost universally run dual-zone setups, but a like-for-like tonnage swap without a load calculation and static pressure check just moves the hot upstairs problem to the new equipment. We see this after replacement jobs done elsewhere: brand-new Lennox or Trane units that still can’t cool the second floor because nobody addressed ductwork leakage or undersized returns.
