Do they need to be at the floor level or at the ceiling level?" In the house above the f...
  • Can I close off the fresh air to the furnace return duct?

  • WHAT IS AN AIR-TO-AIR HEAT EXCHANGER, HRV and ERV?

    Air-change ventilation systems exist that take stale air out and bring fresh air in so as to not rely on cold air drafts for the entry of fresh air to the house.

  • Overview: To HRV-ERV or not to HRV-ERV

    I am always amazed at house construction where so often things are half built or more while people are running around beginning to think about "extras" that should never be though of as "extras" but as part of the essential system. So time for one of my lectures -- (you asked for it).Heating is o...
