Common questions

Can you fix a room that's always cold?

Often yes. Common fixes include balancing dampers, adding or resizing a supply run, adding a return air vent, or sealing leaky ducts.

What is an HRV or ERV?

A heat or energy recovery ventilator brings in fresh outdoor air and exhausts stale air while recovering most of the heat. It's especially useful in newer, tightly sealed homes.
