We have totally gutted the interior of our 105 year old home in Toronto, Canada. EVERYTHING inside will be 100% new.
We have dependants with asthma issues. We want a whole home ventilation system for optimum indoor air quality. We'll be using closed cell spray foam insulation so the home will be fairly tight.
Our west facing backyard and neighbour's yards are jammed full of tall old trees. That minimizes our need for A/C, but we still need to manage humidity.
The simplest, and cheapest way to go it would seem, is a traditional low velocity forced air system.
As I understand it - the ductwork could handle not only the heating and air conditioning, but could also be used for whole home ventilation system?
Could the whole home ventilation system also manage humdity indepently of an AC unit?
We would LOVE to do hydronic heated floors throughout. Nothing beats radiant heat. Having large ductwork running everywhere is a PITA , and with our low basement ceiling - really impacts useable space in the basement.
How do you install whole home ventilation and humidity control without traditional large low velocity ductwork?
Can we use a split A/C system to save costs or would we need a mini-duct A/C system?
Could the mini-ducts themselves be used as the ductwork for a whole home ventilation system, and humidity management?
