Emergency HVAC in Keller, TX
No cool on a 105°F day. No heat on a 25°F night. Gas smell at 2 AM. When HVAC fails, you need flat-rate, honest, fast response. $85 diagnostic, $250 after-hours, $0 overtime for Frosty Club members. Licensed TACLA126718E, EPA 608 Universal certified, family-owned since 2018.
Gas Smell or CO Alarm? Call 911 + Atmos Energy FIRST
Gas smell: Leave the house immediately. Do not flip switches or light matches. From outside, call Atmos Energy: 866-322-8667. Atmos will shut off the gas at the meter. CO alarm sounding: Leave immediately and call 911 from outside. Once safety services have cleared the house, call us at (469) 254-0548 for diagnostic and repair. We NEVER repair cracked heat exchangers — those require full furnace replacement only.
Where in Keller Do We Run Emergency Calls?
Emergency response to Keller runs from our Farmers Branch base — 28 miles via TX-114 West to TX-170, roughly 35 minutes. We cover 76244, 76248, and 76262 including Hidden Lakes, Marshall Ridge, The Oaks of Fossil Ridge, Bloomfield, Estancia, and Shady Grove. Keller sits in Tarrant County.
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.

Join Frosty ClubWhat Counts as an HVAC Emergency in Keller?
Some HVAC problems can wait until tomorrow. Others can't. Here's how I triage emergency calls in Keller — and what to do in each case.
No cooling, 95°F+ summer
Real emergency when elderly, infants, or anyone with medical conditions is in the house. DFW summer heat kills. Move family to coolest room, run fans, stay hydrated, call us immediately.
No heat, below 35°F
Emergency for elderly, infants, and pipe-freeze risk. Usually ignitor, flame sensor, gas valve, or pressure switch. $400-$1,200 range. Same-visit fix when parts are in stock.
Gas smell
LIFE SAFETY. Leave the house immediately, call Atmos Energy 866-322-8667 from outside, then 911. Do not flip switches. Once gas is shut off, call us to diagnose the source and repair.
CO alarm sounding
LIFE SAFETY. Leave the house, call 911 from outside. Usually a cracked heat exchanger (full furnace replacement, we NEVER repair) or vent leak (repairable). Never run the furnace until cleared.
Water leaking from air handler
Clogged condensate drain triggered the safety switch — or the pan overflowed and water is dripping from the ceiling. Shut off the breaker. Call us. Drain clearing runs $350 ($297.50 members).
Electrical burning smell
Shut off the breaker immediately. Usually a failing contactor, blower motor, or wire connection. Do NOT run the system until we diagnose. Repair is $500-$1,500 range.
Why Do Keller Homeowners Call Frosty's for Emergencies?
Keller's emergency call profile is dominated by one fact I never see anywhere else in DFW: 3,500-to-6,000 sqft two-story KISD family homes running two-zone or three-zone communicating systems (Carrier Infinity, Trane ComfortLink II, Lennox iComfort). When a single component fails on a communicating system — one outdoor capacitor, one zone damper motor, one upstairs coil sensor — the thermostat doesn't keep running the other zones. It faults the whole system and locks everything out. So a Hidden Lakes or Marshall Ridge homeowner calls me not because their AC is broken, but because the thermostat flashed a code and shut the entire house down on a 104°F Saturday. We're 35 minutes from Keller, and Frosty Club Premium members get priority on heat-wave calls — on a day when every communicating system in town is throwing codes, priority is the only thing that matters. Call (469) 254-0548, a human answers.
Here's what actually counts as an emergency worth a same-day call in Keller: AC fully down when it's 95°F+ and you have kids, pets, or elderly family (especially in 3,500+ sqft two-story homes where one failed zone can make half the house unlivable); heat fully down when it's below freezing; water pooling from an upstairs air handler onto a ceiling (clogged condensate drain); burning smell or smoke from any part of the system; suspected gas leak (call 911 and gas company first); CO detector going off near the furnace. If both zones are still running and only one is struggling, we can usually save you money by scheduling for tomorrow at regular rates.
Emergency diagnostic is the same $85 flat rate as a scheduled call, waived with any repair. We do not charge emergency surcharges — flat-rate means flat-rate. After-hours service (before 7 AM or after 8 PM) runs $250 for non-members, $212.50 for Frosty Club Basic members, and Premium members pay the regular $85 with no overtime. Keller's 35-minute drive from Farmers Branch means after-hours response times typically land 1.5-2 hours from the call — longer than a Farmers Branch or Coppell emergency, but honest. The phone number is (469) 254-0548 — that rings to Omar or Mariafernanda directly, not a call center.

Why Should I Trust Frosty's Credentials for Emergency HVAC?
Because every credential is independently verifiable and directly tied to the emergency — Texas HVAC Contractor License TACLA126718E regulates how we touch gas and electrical, EPA CO safety guidance governs every cracked-heat-exchanger call, and the U.S. Department of Energy documents why annual maintenance prevents the emergencies in the first place.

EPA Combustion Safety
Per the U.S. EPA CO Safety Guide, cracked heat exchangers are a leading cause of residential CO poisoning. We NEVER repair — full replacement only.
DOE Emergency Preparedness

What Do Keller Homeowners Ask About Emergency HVAC?
Do you offer 24/7 emergency HVAC in Keller?
We offer emergency response during peak heat and cold seasons, and after-hours diagnostic/repair year-round. After-hours call (before 7 AM or after 8 PM) is $250 for non-members, $212.50 for Basic members, and waived to the regular $85 for Premium members. Because Keller is 35 minutes from our shop, after-hours response usually lands 1.5-2 hours from the call. We prioritize no-heat situations in freezes and no-AC situations over 95°F. Call (469) 254-0548.
What counts as an HVAC emergency in Keller?
True emergencies: AC fully down over 95°F with vulnerable family members, heat fully down below freezing, water dripping from the ceiling (clogged upstairs condensate drain), burning smell or visible smoke, gas smell (call gas company first), or CO detector alarm near the furnace. On a dual-zone Keller home where one side is still running, we can usually schedule next-day at regular rates and save you the after-hours fee.
How fast can you get to Keller in an emergency?
We're about 35 minutes from Keller at our Farmers Branch shop, so emergency response during business hours is typically within 1.5-2 hours for Frosty Club members (priority scheduling) and 3-4 hours for non-members during peak weeks. After-hours response is usually within 2 hours. We're honest about the drive — we don't promise a 30-minute ETA we can't keep. A human answers our phone.
Do you charge emergency surcharges in Keller?
No. We're flat-rate, which means flat-rate. Diagnostic is $85 during business hours (waived with repair), and $250 after-hours ($212.50 for Basic members, $85 for Premium members). Repair prices don't change based on time of day — a capacitor is $500 at 2 PM or 2 AM. No 35-mile surcharge, no heat-wave premium, no weekend markup.
My upstairs air handler is leaking water onto my Keller ceiling — is this an emergency?
Yes, treat it as urgent. In Keller's 3,500+ sqft two-story homes, the upstairs air handler typically sits in the attic directly above a bedroom or hallway, and a clogged condensate drain can drop water onto drywall fast. We clear the drain ($350, $297.50 for members) and install a float switch ($400) to prevent a repeat. Left alone, a clog causes drywall damage, mold growth, and ruined attic insulation. Call (469) 254-0548.
Do You Handle Emergency R-22 AC Failures 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 for DFW homeowners.
Do You Handle Emergency R-410A AC Failures in Hidden Lakes and Marshall Ridge?
Yes — EPA 608 Universal cert #2396328 covers R-410A diagnosis, leak detection, and recharge. AIM Act 2025 phase-out (Energy.gov) affects new equipment manufacturing, not service work. For a Hidden Lakes and Marshall Ridge R-410A emergency, expect $250 electronic leak detection (or $500 nitrogen for complex leaks) plus recharge at $100/lb installed. Most repairs run same-day. Read our R-410A phase-out explainer for DFW homeowners.
