I thought I'd pass along all the recommendations I received:
  • Wade Heating & Cooling has been taking care of my A/C units, and furnace too, for ~15 years now.  They've been pretty reliable.
  • Gary Moore of Arch Moore Heating & A/C, 412/731/7900 is a master.
  • Anthony Stamatopolis--412.926.0587.  Alpha to Omega HVAC.
  • We’ve had excellent service on our system from Tudi Mechanical.
  • Air Pro --reasonable prices  800-749-0642.
  • Accurate heating and air conditioning.
  • Paul Tedesco. He's a local guy.
