McKinney's rapid growth has created a diverse housing landscape—from historic homes in downtown McKinney to sprawling master-planned communities like Stonebridge Ranch and Craig Ranch, and the modern Mediterranean-style architecture of Adriatica. Each neighborhood faces unique AC challenges: older downtown homes often need ductwork updates and system replacements, while newer developments deal with warranty-expired builder-grade units and North Texas heat stress. When temperatures hit 105°F in July and August, your air conditioner isn't just a convenience—it's essential for your family's safety and comfort.

Learn MoreIf your AC is blowing warm air or cycling constantly, you may have a refrigerant leak. We use electronic leak detection to pinpoint leaks, repair them properly, and recharge your system to manufacturer specs—no guesswork, just results.
Learn MoreCompressor failure is one of the most serious AC problems. We'll diagnose whether your compressor can be repaired or needs replacement, provide upfront pricing, and explain your options—including whether a full system replacement makes more financial sense.
Learn MoreWeak airflow, strange noises, or no air at all? Your blower motor may be failing. We repair or replace blower motors and capacitors quickly, restoring proper airflow and cooling to your McKinney home—often the same day you call.
Learn MoreThermostat issues can mimic major AC problems. We diagnose faulty wiring, calibration errors, and dead batteries, and can upgrade you to a smart thermostat like Nest or Ecobee for better comfort and energy savings.
Learn MorePrevent breakdowns before they happen. Our preventive maintenance plans include annual tune-ups, priority scheduling, and discounts on repairs. Keep your AC running efficiently and extend its lifespan with regular professional service.
Learn MoreDon't wait until your AC completely fails. These warning signs mean it's time to call LEX Air for professional repair.
If your AC is running but blowing warm or room-temperature air, you likely have a refrigerant leak, compressor failure, or thermostat issue. This requires immediate professional diagnosis—don't wait in the heat.
Grinding, squealing, banging, or rattling sounds indicate mechanical problems—worn bearings, loose parts, or failing motors. Ignoring these noises leads to expensive damage and potential system failure.
Reduced airflow from vents usually means a clogged filter, failing blower motor, or ductwork issues. This forces your system to work harder, increases energy bills, and shortens its lifespan.
If your AC turns on and off constantly (short-cycling), you have a serious problem—refrigerant leaks, electrical issues, or an oversized system. This wastes energy and damages components quickly.
Your AC should remove humidity as it cools. If your McKinney home feels muggy even with the AC running, you may have refrigerant issues, a failing compressor, or undersized equipment.
Musty odors indicate mold in your ductwork or evaporator coil. Burning smells suggest electrical problems or overheating motors. Both require immediate professional attention for safety and health.
"Our AC died at 9 PM on a Friday in July—house was 84 degrees with two kids trying to sleep. Called LEX and they had a tech at our Stonebridge house in 20 minutes. Found a bad capacitor, replaced it on the spot, and we were cool again by 10. Honest pricing, no upselling, just great service. Can't recommend them enough."

We offer 24/7 emergency service—no extra fees for nights, weekends, or holidays.
AC repair costs vary based on the problem—simple fixes like capacitor replacements run $150-$300, while major repairs like compressor replacements can cost $1,200-$2,500. We provide upfront pricing before starting any work, offer free diagnostics with repairs, and never charge hidden fees. Most McKinney homeowners pay $200-$600 for common AC repairs.

If your AC is under 10 years old and the repair costs less than half the price of a new system, repair usually makes sense. For older systems (12+ years) with major failures like compressor or coil issues, replacement often saves money long-term through better efficiency and reliability. We'll give you honest advice about both options with transparent pricing—no pressure, just facts.

North Texas summers are brutal on AC systems. The most common failures we see in McKinney are capacitor burnouts (from constant use in 100°F+ heat), refrigerant leaks (from UV exposure and vibration), and compressor failures (from overwork). Clogged filters and dirty coils force systems to work harder, accelerating wear. Regular maintenance prevents most of these issues and extends your system's life by 5-7 years.
