Armstrong is proud to have been part of a major commercial project at Texas Tech University. We were the HVAC and Plumbing contractor for the new West Village dorm/apartment complex.

  • The challenge: How to heat and cool a structure not connected to the university’s current system.
  • The answer: A commercial sized version of the mini-split heat pump that goes into your home.
  • The result: Energy savings and custom temperature controls using Variable Refrigerant Flow (VRF) technology.
