I recently had Pittsburgh Air Systems / Air Industrial Inc. replace my old furnace and I couldn't be happier with their service. The technicians were knowledgeable and friendly. They arrived on time, completed the installation efficiently, and cleaned up after themselves. The new furnace works perfectly and I noticed an improvement in my energy bills as well. I highly recommend this company to anyone in need of HVAC services.
