systems are blessed with big opportunities for improvement. This session will help you perform triage and get results
with minimal time and expense. You will get field practical answers to these questions:
My temperature rise is too high - is it the ducts?
How do I
tell if my problem is in the supply or return?
How can I tell if my furnace is going to cycle on the limit switch if I seal the ducts?
I have an
eighty thousand BTU input furnace with six, six inch supplies – is that enough for this furnace?
By attending this session, participants
will
1. Learn how to increase air flow
through the air handler by decreasing resistance caused by duct design
2. Be able to recognize duct system flaws that decrease homeowner comfort and increase equipment performance and durability
problems
3. Find out how to quickly
determine if a return duct is undersized
