Join Frosty ClubWhat Are the Most Common AC Problems in Richardson?
In my 8 years servicing Richardsonhomes, 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 RichardsonHomeowners Trust Frosty's for AC Repair
Richardson is about 15 minutes from our Farmers Branch shop, and the AC repair calls we get there are dominated by aging equipment in 1960s-1990s housing stock. Canyon Creek (1970s), Arapaho Heights (1960s-70s), Huntington Park, and Cottonwood Heights are full of single-story ranch and split-level homes running 18-25 year old systems — and a surprising number still have R-22 charged in them. Most of those calls come down to four parts: capacitors ($500), contactors ($600), condenser fan motors, and TXV/expansion valve issues on systems that have lost charge over the years from microleaks at flare fittings. Eastern Richardson built out in the 1990s-2000s, so those failures look more like ECM blower boards and zoning issues.
Richardson sits on the same North Texas clay soil as the rest of DFW, and the foundation movement here is real — I see ductwork pulled apart at trunk-to-plenum joints and supply runs disconnected from boots in attics across Canyon Creek and Arapaho Heights. When the slab shifts a half inch over a decade, the rigid metal plenum and the flex duct connected to it don't move together. That shows up as rooms that won't cool, weak airflow at registers, and a system that runs constantly without ever satisfying the thermostat. The fix is duct sealing or replacement, not a refrigerant top-off.
Like Plano, Richardson has a heavy work-from-home population — UT Dallas faculty and staff, plus residents who work remotely for the tech employers along the corridor (AT&T, Verizon, Cisco, Texas Instruments are all nearby). Practically, that means your home HVAC is running 14+ hours a day, year-round, and the duty cycle is double what manufacturers design for. Every repair we do is flat-rate — the price I quote at the start is the price you pay.

AC Repair FAQ for Richardson, TX
How much does AC repair cost in Richardson, TX?
Our diagnostic is $85 flat (waived with any repair). Most Richardson repairs land 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 before we touch a wrench.
My Canyon Creek 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 1970s-era Canyon Creek and Arapaho Heights homes with major leaks or compressor failures, I'll quote both repair and replacement so you can compare. New installs are R-454B or R-32 only.
Do you offer same-day AC repair in Richardson?
Yes — we're 15 minutes from Richardson, so same-day calls are routine. Frosty Club members get priority scheduling and jump the line during 105°F heat waves. Call (469) 254-0548 and we'll give you a real ETA, not a 4-hour window.
Why does my Richardson AC short-cycle on and off?
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 older Arapaho Heights and Huntington Park homes. The $85 diagnostic (waived with repair) identifies which one, and we fix it flat-rate.
My AC keeps losing refrigerant — do you just recharge it?
No, and nobody honest should. HVAC systems are hermetic — sealed at the factory. If refrigerant is low, there's a leak. We locate the leak first (electronic detector + nitrogen pressure test), repair it, then recharge to the manufacturer's nameplate spec. Find-fix-recharge runs $350-$1,000 flat depending on leak location. Anyone who just tops it off is wasting your money.
