New Installation — Keller, TX - Texas Air Doctors Skip to main content


Chippendale after

At this project, our HVAC contractors installed a new 4-Ton 25 Seer Lennox gas system. This new system includes:

  • Furnace
  • Condenser
  • Coil
  • Plenums
  • Drain Pan
  • Overflow Safety Switch
  • Pad
  • Whip
  • Disconnect
  • Surge Protectors
  • Pure Air Filter System
  • S 30 Thermostat
  • Balancing Dampers

This new HVAC system is much more effective and efficient than the homeowner’s older system. The S 30 thermostat is a touch screen that’s easy to use, responsive, and provides more information than standard thermostats.
