Most air conditioning repairs in McKinney range from $150 to $650, depending on the issue. We'll always provide a written estimate before any work begins, and our No-Sweat Pricing guarantee means that the number we quote is the number you pay. Plus, we'll waive our diagnostic fee when you move forward with the repair.

Yes, the City of McKinney requires a mechanical permit for HVAC replacement and installation, including both AC and heater/ furnace replacement, applied for through the McKinney CSS Portal. McKinney adopted the 2024 IRC/IBC family of codes effective October 1, 2025. At Koala-T, we'll pull the required permit for every replacement job. If a contractor tells you a permit isn’t needed, that’s a red flag.

McKinney is split between two electric utilities: Oncor Electric Delivery and CoServ Electric. Both offer rebates on qualifying high-efficiency HVAC equipment, but the programs and amounts differ. Oncor’s “Take a Load Off Texas” program covers central AC, heat pumps, ductless mini-splits, smart thermostats, and duct sealing. CoServ runs its own rebate programs for cooperative members. If you're not sure which utility serves your home, we'll help you figure it out, and we'll complete any paperwork on your behalf.

In the North Texas climate, a well-maintained cooling system in McKinney typically lasts from 12 to 18 years. McKinney’s extreme summer heat and hard Lavon Lake water, along with the area's Blackland Prairie clay soil (which can cause condenser pads and stress line sets to move), can shorten that lifespan without proper maintenance. If your system is 15+ years old, uses R-22 refrigerant, or needs frequent repairs, we recommend getting a free replacement estimate from our HVAC company.

The best HVAC solution for homes in McKinney’s Historic District (1880s–1930s) is a ductless mini-split heat pump, which provides efficient heating and cooling without requiring ductwork. Plus, the indoor heads are compact enough to work in rooms with high ceilings and limited wall space. You don’t have to deal with paperwork or worry about breaking any local historic building rules — we'll handle it all and make sure everything is approved and installed correctly.

If your McKinney home was built between 2012 and 2016 (common in Trinity Falls Phase 1 and parts of Craig Ranch), your original HVAC system’s 10-year compressor and coil warranty may be expiring or has recently expired. This is the window when major failures become common. Before you agree to a replacement, get a free second opinion from Koala-T. Many systems at this age can be repaired, so you don't need to invest in a full replacement.

At a minimum, we recommend that McKinney homeowners service their air conditioning units once a year in early spring before temperatures climb. In McKinney’s climate, we recommend twice-yearly maintenance: a spring AC tune-up and a fall furnace/heat pump check. This is the best way to maintain system efficiency and reduce the likelihood of unexpected breakdown. Our Joey Club™ membership plan covers both visits plus priority scheduling and discounted repairs. If you live in an area with heavy tree canopy, like Stonebridge Ranch or Westridge, you should also have your condenser coils cleaned more frequently.
