ERV vs HRV in Plymouth, MN — West Metro Lakes, Tight Homes, Clear Recommendation
Plymouth sits in the west metro with lake-adjacent neighborhoods, established streets near Medicine Lake, and continuing infill that keeps envelopes tighter every year. Homeowners here usually aren't shopping for a gadget — they're trying to stop winter window fog or stop a new house from feeling like a desert. That is exactly the HRV vs ERV fork, and Furnace Direct installs whichever side your Plymouth home actually needs.

Why Plymouth hits both problems
Lake-proximate established homes often show classic condensation after upgrades. Corridor and newer Plymouth construction shows dryness when continuous ventilation is underspecified or the wrong core is used. Same city name; different physics indoors.
HRV — Plymouth's humidity answer
Heat recovery ventilator: outdoor air in, stale air out, heat transferred, moisture largely exhausted. Right when Plymouth windows fog and indoor RH climbs in January.
ERV — Plymouth's dryness answer
Energy recovery ventilator: heat plus a share of moisture transferred. Right when a tight Plymouth home already sits too dry and still needs code-friendly continuous air exchange.
What we need for a Plymouth quote
Approximate year built, any recent sealing/windows, whether glass fogs, and a rough indoor RH if you have it. Photos of an existing exchanger speed replacement quotes.
