This weekend, while B was on an island with Norah, I undertook installing an air exchanger in our house. Since having the basement spray foamed in the summer, we have not had enough air movement in the house. Our humidity levels were through the roof, causing water to form on the windows regularly. The solution is an air exchanger, which takes out humid air from your bathrooms and kitchen and brings in fresh air to replace it. Since our kitchen and bathroom don’t have exhaust fans, this was especially needed in our house. My uncle got me the parts at cost and explained how to do it. I undertook the job, which involved completing the following tasks:
run return vent – bathroom
run return vent – kitchen
run return vent – basement bathroom
join returns
hang air exchanger
bore 6” hole for exhaust
install exhaust vent
bore out 4” intake to 6”
install intake vent
run intake hose
install humidistat next to thermostat
install lighted timer switch in bathroom
wire switches to air exchanger
wire air exchanger to furnace
While this list doesn’t look that bad (which is what I thought before undertaking the task) it ended up being a three day job. I also called on four friends to come help with parts that were made much easier by having a second person, or where my expertise was lacking. Stephen, our electrician friend, did an admirable job of filling in for my dad, as he came to my rescue twice with quick solutions to problems that Dad would have normally troubleshot with me.
I worked on Thursday from 4:30 – 10:30, Friday (I took my one personal day from work) from 8:00 – 6:00 and from 8:00 – 10:30 and Saturday from 8:00 – 5:30. However, it is now done! To have a plumbing company do the same job (which they aren’t too excited about doing since retro-fitting returns is messy work) would have cost at least $5000. In the end the whole job cost me less than $1000, not including my time. And I will get $675 back from the Energuide program.
Here are some pics showing the final result:

The exhaust vents from the bathrooms (silver) and the fresh air intake from outside (black insulated pipe.)

In this time, I also did the following jobs that had been piling up:
move shelving unit to garage
finish gutting basement
finish drywall in storage room
staple up hanging wires
move drywall to side
repair fixtures in bathroom
re-caulk tub surround
seal wall behind dishwasher
re-route power to garage
vacuum basement w/shop vac
However, now that I’m done, I’m ready for B and Norah to come home…Seriously. They were storm stayed another night in Victoria, giving me time to write this post. However, I would have rather not written it and seen my girls!!
