When your air conditioner stops cooling in a Midlothian or DFW summer, you need a technician who finds the real problem and fixes it right the first time. Modern HVAC repairs central air conditioners, heat pumps and ductless mini-splits from every major manufacturer across Midlothian, Dallas, Waxahachie, Mansfield and surrounding cities, with clear options and pricing before any work begins.

Common AC Problems We Fix

  • AC running but blowing warm air
  • Outdoor unit not turning on
  • Frozen evaporator coil or iced refrigerant lines
  • Refrigerant leaks and low charge
  • Failed capacitors, contactors and fan motors
  • Water leaks and clogged condensate drains
  • Short cycling, strange noises or burning smells
  • Thermostat and control problems

How Our AC Repair Works

We start by listening to what you’ve noticed, then test the system from the thermostat to the outdoor unit: electrical components, refrigerant pressures, airflow, coils and drains. Once we find the cause, we explain it in plain language and give you options. If the system is older and repair costs are adding up, we’ll tell you honestly whether repair or replacement makes more sense, and we never push equipment you don’t need.

Repair or Replace?

Many repairs are simple and affordable. But if your system is more than 12–15 years old, uses outdated refrigerant or needs a major component like a compressor, replacement may save money long term. We’ll walk you through both paths, including high-efficiency Daikin inverter systems.

“Excellent service! Honest, reliable, and knowledgeable. They were able to diagnose and fix an issue with our AC that several other companies couldn't figure out. Highly recommend!”

“Modern HVAC and its owner, Franklin Phillips, provide the finest HVAC service I have ever experienced. They respond quickly and explain everything they plan to do and why. We have had two HVAC emergencies (once having our home struck by lighting) and Modern HVAC acted expeditiously to get our system up and running in the shortest amount of time. I wouldn't dream of using anyone else!”
