Whole-home heating in Maryland
In Maryland, heating systems run for months at a time (IECC zone 5 at the coldest), so weaknesses in ducts and controls cost real money. A leaky duct run in an unheated attic loses the most heat when the attic is coldest, which in Maryland is most of the winter.
Common heating fuels here: natural gas, electricity, heating oil. Electric baseboard and wall heaters and heat pumps are part of the mix, so breaker, element and line-voltage thermostat problems are common calls.
Western Maryland gets mountain snow, while the Baltimore-Washington corridor deals with ice and quick freezes. A whole-home check covers the thermostat, the heat source, ducts and returns, so the fix reaches the rooms that are actually cold.
