Join Frosty ClubWhat Counts as an HVAC Emergency in Prosper?
Some HVAC problems can wait until tomorrow. Others can't. Here's how I triage emergency calls in Prosper — 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 ProsperHomeowners Call Frosty's for Emergencies
Prosper emergency calls peak during three windows: the first 100°F+ stretch of summer (mid-June through July), the first hard freeze of winter (usually mid-December), and any thunderstorm event that knocks capacitors out across Collin County. We're 40 minutes from Prosper on the Dallas North Tollway, so real emergency response — not just a next-day appointment — is usually within 60-90 minutes for Frosty Club Premium members and within 2-3 hours for everyone else. That 40-minute drive is the reason Prosper customers lean heavily on Frosty Club Premium: priority scheduling jumps you to the front during heat waves, and no overtime charges apply regardless of when you call.
Here's what actually counts as an emergency worth a same-day call in Prosper: AC fully down when it's 95°F+ and you have kids, pets, or elderly family in the house (a 5,000 sqft home with three zones and no cooling gets dangerous fast); heat fully down when it's below freezing; water pooling from the attic onto a ceiling (clogged condensate drain on a zoning system with multiple evaporator coils can dump into a big space); 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 you're comfortable and nothing is actively damaging the house, we can usually save you money by scheduling for tomorrow.
Emergency diagnostic is the same $85 flat rate as a scheduled call, waived with any repair. We do not charge emergency surcharges or Prosper-specific mileage — 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. The phone number is (469) 254-0548 — that rings to Omar or Mariafernanda directly, not a call center.

Emergency HVAC FAQ for Prosper, TX
Do you offer emergency HVAC service in Prosper?
Yes. We're 40 minutes from Prosper on the Dallas North Tollway. Emergency response during business hours is typically within 60-90 minutes for Frosty Club Premium members and 2-3 hours for non-members. 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. Call (469) 254-0548.
What counts as an HVAC emergency in Prosper?
True emergencies: AC fully down over 95°F with vulnerable family members, heat fully down below freezing, water dripping from the ceiling (clogged condensate drain on a zoned system), burning smell or visible smoke, gas smell (call gas company first), or CO detector alarm near the furnace. For large Prosper homes with multi-zone systems, a single failed zone at 100°F+ can make 2,500 sqft unlivable — that's also worth the emergency call.
Do you charge extra for driving out to Prosper?
No. We don't charge mileage, zone surcharges, or Prosper-specific premiums. Diagnostic is $85 flat (waived with repair) regardless of whether you're in Farmers Branch or Windsong Ranch. The 40-minute drive from our shop is our problem, not yours — that's what flat-rate means.
How fast can you reach Windsong Ranch in an emergency?
Windsong Ranch is the deepest part of Prosper we service. Drive time from our Farmers Branch shop is 40-50 minutes depending on Dallas North Tollway traffic. During business hours, Frosty Club Premium members typically see us within 90 minutes; non-members within 2-3 hours. After-hours we prioritize no-heat freeze calls and no-AC 100°F+ calls over general emergencies.
My AC is leaking water onto my ceiling in Prosper — is this an emergency?
Yes, treat it as urgent. Most Prosper homes have multi-zone systems with primary and secondary evaporator coils, and either drain pan can overflow fast when the condensate line clogs. We clear the drain ($350, $297.50 for members) and install a float switch ($400) to prevent a repeat. Left alone, a clog can soak drywall, start mold growth, and ruin attic insulation. Call (469) 254-0548.
