Frequently Asked Questions
How much does AC repair cost in McKinney, TX?
AC repairs in McKinney range from $150 for a basic capacitor swap to $800 for a blower motor replacement. Refrigerant recharge runs $200 to $500. Full system replacements cost $4,500 to $8,500 for a 3-ton unit installed. McKinney pricing runs roughly 10 percent above Austin rates, reflecting the DFW labor market and high demand during the June-September peak season.
How often should I service my AC in McKinney?
Annual maintenance before summer -- ideally in March or April -- is essential in McKinney. North Texas summers are brutal, routinely hitting 100 to 108 degrees from June through August. Without a spring tune-up, refrigerant levels drop, coils foul, and capacitors fail at the worst possible moment. Most McKinney HVAC companies offer annual maintenance agreements that save 15 to 20 percent on service calls.
Why does my AC freeze up in McKinney summers?
Frozen AC coils in McKinney are usually caused by low refrigerant, a dirty air filter restricting airflow, or a failing blower motor. The combination of record heat and high humidity accelerates coil icing. Turn the system to fan only, let it thaw completely (two to four hours), replace the filter, and call a tech if it refreezes. Running a frozen system risks compressor damage, which is a $1,500 to $3,000 repair.
What size AC do I need for a McKinney home?
Most McKinney single-family homes need 3 to 5 tons of cooling capacity. A 2,000 sq ft home typically requires a 3 to 3.5-ton unit, while a 3,500 sq ft Craig Ranch or Stonebridge Ranch home may need 4 to 5 tons. Proper Manual J load calculations are required by Texas code -- avoid any contractor who quotes a system without measuring your home.
