Holmes on Homes (2003)

Season 7: Episode 4

The Holmes Crew inspects a house that has had intermittent heating issues in the six years since it was built, yet had gone unaddressed by the builder or Ontario's New Home Warranty Program (due to a series of bureaucratic issues and "band-aid" remedies). The problem was discovered to have been caused in part by alterations to the design of the house having been done without necessary matching alterations to the HVAC system, thus forcing Holmes and his crew to completely replace the HVAC, hot water, and electrical systems.
