[Highland Park] HVAC recommendations

Hi, We're in need of recommendations for HVAC systems and, more importantly, installers. We've delayed in replacing the old system (it just won't die!) for too long; it's time to "energy save". All recommendations are welcomed. Also, we've completed third floor renovations and need a good, reliable, and not outrageously priced painter. Please send all recommendations to: mcato@telerama.com. Many thanks, Maureen and Wibb Cato
