How many of us really know much about the most complicated and expensive systems typically found in our homes - the Heating, Ventilation, and Air Conditioning (HVAC) systems? These units always seem to fail at the worst possible time, making it very difficult to objectively consider our alternatives for system repair or replacement while uncomfortable and needing relief. How do these systems actually work, and what kind of maintenance & troubleshooting can we do ourselves to help our HVAC equipment run better and possibly minimize our repair costs? Your presenter, Jack Granger, Wolfhound alumni parent, will cover these topics and more, leaving you better prepared to deal with your HVAC system, giving you some peace of mind and very likely saving you money! CLASS LOCATION/TIME: Saint Patrick Catholic School, 7:00-9:00 pm.
