Now serving Keller
Keller is about 35 minutes from our Farmers Branch shop via TX-114 west to TX-170. We try to batch Keller routes to keep response time tight, so book early when possible. We stock ECM blower modules, zoning control boards, and TXV kits for the Carrier Infinity / Trane XV communicating dual-zone systems common in Hidden Lakes, Marshall Ridge, Estancia, and the Oaks of Fossil Ridge.
Keller climate context
Keller homes are predominantly 3,500-5,500 sqft custom two-stories on half-acre-plus lots built 1995-2015, almost all running dual-zone HVAC with two air handlers, two condensers, and zoning dampers. The half-acre-plus lots also mean longer refrigerant line sets — leaks have more places to hide, and TXV / ECM control-board faults on the upstairs zone are the dominant Keller failure mode rather than capacitor or contactor issues.
How Much Does AC Repair Cost in Keller?
AC repair in Keller starts at $85 for the diagnostic (waived with any repair). Most common repairs fall in the $350-$1,500 range — we're flat rate, which means the price we quote before we start is the price you pay at the end. Frosty Club members save 10-15% on every repair.

Join Frosty ClubWhat Are the Most Common AC Problems in Keller?
In my 8 years servicing Keller homes, 80% of the emergency repair calls I get come down to a handful of issues. Here's what I see most often — and what each one typically costs to fix.
AC won't turn on
Usually a failed capacitor ($500), contactor ($600), or a tripped float switch. Diagnostic identifies the exact cause.
Blowing warm air
Low refrigerant from a leak, failed compressor, or iced-over evaporator coil. We find and fix leaks — we never gas-and-go.
Frozen evaporator coil
Restricted airflow or low refrigerant. Shut the system off and call us before it destroys the compressor.
Water leaking from indoor unit
Clogged drain line ($350) or damaged drain pan ($1,200). A $400 float switch prevents future water damage.
Loud grinding or rattling
Worn blower motor bearings, loose fan blade, or failing compressor. Don't ignore it — small noises become big repairs fast.
Short cycling (on/off/on/off)
Weak capacitor, oversized system, failing thermostat, or refrigerant problem. Short cycling kills compressors in under a year.
Why Do Keller Homeowners Choose Frosty's for AC Repair?
Keller is about 35 minutes from our Farmers Branch shop, and the AC repair calls we get up there are almost always on larger custom homes built between the 1990s and 2010s. Hidden Lakes, Marshall Ridge, The Oaks of Fossil Ridge, Bloomfield, and Estancia are full of 3,500-5,500 sqft two-story builds on half-acre-plus lots, and most of them came from the builder with dual-zone HVAC — two air handlers, two condensers, zone dampers, and two thermostats. That means when something fails, we have to figure out which of the two systems it is before we quote anything. Upstairs zone not cooling doesn't always mean the upstairs system is bad — sometimes it's a zoning board, a damper motor, or a communicating thermostat that lost sync with the air handler.
Because these are newer homes, the failure profile is different from older DFW cities. We see a lot of ECM variable-speed blower motor failures ($750-$2,800 depending on the model), zoning control boards that stop talking to the thermostat, TXV (thermostatic expansion valve) issues on the upstairs coil, and communicating-system faults on Carrier Infinity and Trane XV systems. The KISD school district keeps families planted in Keller for 10-20 years, which means we end up seeing the same homes multiple times — and that longevity is exactly why we push Frosty Club membership for Keller. The half-acre-plus lots also mean longer refrigerant line sets, which gives leaks more places to hide — we locate the leak first, repair it, then recharge to manufacturer spec (hermetic systems rule; anyone just topping off refrigerant is wasting your money).
Every repair we do in Keller is flat-rate — the price I quote at the start is the price you pay, on a 3-ton single-stage or a 5-ton dual-compressor variable-speed job. I'm EPA 608 Universal certified (#2396328), Mariafernanda is the license holder (TACLA126718E), and we've been doing this since January 1, 2018. 99 Google reviews at 4.9 stars. The 35-minute drive from Farmers Branch means scheduling a Keller call takes a little more planning than an Irving or Coppell job — we try to batch Keller routes when we can — so book early if you can. Call (469) 254-0548.

What Do Keller Homeowners Ask About AC Repair?
How much does AC repair cost in Keller, TX?
Our diagnostic is $85 flat (waived with any repair). Most Keller repairs fall between $350 and $1,500: capacitor $500 ($425 for Frosty Club members), contactor $600 ($510), standard blower motor $750-$1,500, ECM variable-speed blower $1,500-$2,800 ($1,275-$2,380 for members), refrigerant leak find-fix-recharge $350-$1,000. Dual-zone systems sometimes mean both sides need attention — we quote each side separately so you see exactly what you're paying for.
My Hidden Lakes home has dual-zone HVAC — can you work on communicating systems?
Yes. Hidden Lakes, Marshall Ridge, Estancia, and most Keller custom homes built 1995 and later run Carrier Infinity, Trane XV, or similar communicating dual-zone setups with two air handlers, two condensers, and zoning dampers. We're trained on the diagnostic protocols for all major brands and can pull fault codes, check damper motor response, and verify thermostat-to-air-handler communication. The $85 diagnostic identifies whether it's a zoning board, damper motor, or actual refrigeration issue.
Do you offer same-day AC repair in Keller?
We do our best, but Keller is about 35 minutes from our Farmers Branch shop, so same-day isn't always possible — especially during 100°F+ stretches when calls stack up. Frosty Club members get priority scheduling and jump the line. For standard calls, we usually can get to Keller next-day or within 48 hours. Call (469) 254-0548 and we'll give you a real ETA, not a 4-hour window.
Why does my Keller upstairs zone run constantly while downstairs is fine?
On a dual-zone Keller home, this is almost always one of three things: a failing TXV on the upstairs coil (most common), an ECM blower motor that's derated and can't push enough CFM to the upstairs registers, or a zoning damper stuck in the wrong position. Long duct runs in 3,500+ sqft two-story homes compound the problem. Our $85 diagnostic identifies the exact cause — it is almost never a thermostat issue, and adding more zoning won't fix airflow or refrigerant metering problems.
My Keller home has a refrigerant leak — do you just recharge it?
No. HVAC systems are hermetic — sealed. If refrigerant is low, there's a leak. Anyone who just tops it off is wasting your money because the refrigerant will leak right back out. We locate the leak first (electronic leak detector and nitrogen pressure test), repair it, then recharge to manufacturer spec. Long line sets on Keller's half-acre-plus lots give leaks more places to hide, so a thorough search is especially important here. Total for find-fix-recharge runs $350-$1,000 flat-rate.
Can You Still Repair My R-22 System in Hidden Lakes and Marshall Ridge?
Yes — EPA 608 Universal cert #2396328 lets me legally recover, recycle, and recharge R-22 under federal regulations. R-22 production ended in 2020 under the Clean Air Act phase-out (EPA.gov), so it now runs $200 per pound installed. A typical Hidden Lakes and Marshall Ridge R-22 leak repair totals $650-$1,000: electronic leak detection ($250) or nitrogen leak test ($500) plus recharge at $200/lb. Optional leak seal $350 — but it can void manufacturer warranties, so I only recommend it in specific cases. For systems past 12 years with major leaks, planning the transition to R-454B or R-32 is usually the better economics. Read our R-410A phase-out explainer.
Should I Repair My R-410A System in Hidden Lakes and Marshall Ridge or Replace It?
Yes, I can repair it — R-410A production for new equipment ended Jan 2025 under the AIM Act (Energy.gov), but EPA 608 Universal cert #2396328 covers ongoing service. R-410A recharge runs $100 per pound installed. A typical Hidden Lakes and Marshall Ridge leak repair totals $450-$700: electronic leak detection ($250) or nitrogen leak test ($500) plus recharge at $100/lb. Optional leak seal $350 — but it can void manufacturer warranties, so I only recommend it in specific cases. For systems past 12 years with major leaks, replacement to R-454B or R-32 is usually the better economics. Read our R-410A phase-out explainer.
