Join Frosty ClubWhat Are the Most Common AC Problems in McKinney?
In my 8 years servicing McKinneyhomes, 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 McKinneyHomeowners Trust Frosty's for AC Repair
McKinney is about 35 minutes from our Farmers Branch shop straight up US-75, and the AC repair calls we get there split sharply by neighborhood era. Historic Downtown McKinney — the pre-1950 housing stock around the square and along Tucker, Howell, and Anthony streets — is the toughest service work in Collin County. Most of those homes are pier-and-beam with crawlspace ductwork, original 2.5-3 ton R-22 systems retrofitted into closets that were never designed for HVAC equipment, and electrical panels that haven't been touched since the Carter administration. Capacitor, contactor, and condensate drain calls dominate. Stonebridge Ranch (built 1988-2005) and Craig Ranch (2000-2015) are the opposite story — variable-speed ECM blower boards, zoning dampers that quit responding, and TXV issues on golf-course-adjacent two-stories where the upstairs bedrooms sit 8-12°F hotter than the great room.
McKinney's growth pattern matters for HVAC because it means a single ZIP code (75070, 75071, 75072) can have 1990s Stonebridge Ranch homes hitting their second compressor right next door to 2012 Craig Ranch builds where the original variable-speed equipment is just now showing wear on the ECM blower modules. Adriatica's 2010s mixed-use village layout is mostly newer high-efficiency equipment, but the dense layout means line sets sometimes run further than the original installer accounted for, and we see refrigerant charge issues on systems that were marginal from day one. McKinney homeowners also tend to set tighter setpoints than the DFW average — 71-73°F is common — which adds runtime hours and shortens capacitor life.
Every repair we do in McKinney is flat-rate — the price I quote at the start is the price you pay.

AC Repair FAQ for McKinney, TX
How much does AC repair cost in McKinney, TX?
Our diagnostic is $85 flat (waived with any repair). Most McKinney repairs fall between $350 and $1,500: capacitor $500 ($425 for Frosty Club members), contactor $600 ($510), blower motor $750-$1,500 ($637.50-$1,275 for members), refrigerant leak find-fix-recharge $350-$1,000. We never quote by the hour — you see the total price before we touch a wrench.
Why is my upstairs hotter than downstairs in my Stonebridge Ranch or Craig Ranch home?
In 2-story McKinney homes in Stonebridge Ranch and Craig Ranch, the usual suspects are a failing TXV (thermostatic expansion valve) on the upstairs zone, a blower motor running under-spec, or a zoning damper that's stuck open or closed. Our $85 diagnostic finds the exact cause. It's almost never a thermostat problem, and adding more zoning won't fix an airflow or refrigerant metering issue.
Do you offer same-day AC repair in McKinney?
Yes — we're 35 minutes from McKinney up US-75, so same-day calls are routine if we hear from you before noon. Frosty Club members get priority scheduling and jump the line even during 105°F heat waves. Call (469) 254-0548 and we'll give you a real ETA, not a 4-hour window.
My Historic Downtown McKinney home has an R-22 system — can you still repair it?
Yes. I'm EPA 608 Universal certified, so we can legally recover, recycle, and recharge R-22. But R-22 hasn't been produced since 2020 and now runs $150-$200 per pound. For pre-1950 Historic Downtown homes with major leaks or compressor failures, I'll quote both repair and replacement so you can compare. Pier-and-beam retrofit work is its own challenge — I'll walk you through the trade-offs honestly. New installs are R-454B or R-32 only.
Why does my McKinney AC keep short-cycling?
Short cycling — system turning on and off every few minutes — usually means one of three things: a dirty/iced evaporator coil (restricted airflow), a failing capacitor causing hard-start issues, or an oversized system that was installed wrong from day one. We see all three in McKinney. The $85 diagnostic (waived with repair) identifies which one, and we fix it flat-rate.
