Heating, Air Conditioning, Fridge, HVAC/duct work (basement)


Hi there, we live in Ontario Canada so temps are warm in the summer and cold in the winter. We are looking at finishing the basement (1200 sq ft) from it's current "bare wall" state. Before I start to frame it I was wondering if I should leave the vents coming out of the ceiling from where my builder put them, or if I should move it so that the  round duct pipe down the wall and put a register for the heat and a/c from just above the floor? If it makes a difference we plan on dry-walling the ceiling and having pot lights in there as well.

Thanks in advance for any help you can provide.

First, the basement should be a separate zone with its own thermostat. That'll require some duct modifications, adding zone controls, etc.

Second, you're in a heating climate (The highest Ontario design temperature is 6F!!!), so do locate the outlets near the floor.

Assuming you have an oil or gas furnace, seal all the return ductwork within the room containing the furnace and provide a basement return grille outside that room.

I can't help you if your whatsis won't work, people (Especially if it's a refrigerator); I have no experience with appliances, and I haven't been involved with H&AC service and repair since March 08, 1996 (Thank the Lord); I always send a "standard" reply to appliance questions and H&AC "Service and Repair" questions (about 20 a month), so if you want to know why your whatsis isn't working like it used to, ask someone else. A lot of my answers arenít read by the questioners; in that event, I always send reminders to read the answers for a month or more (the word "idiots" comes to mind - actually there's another more appropriate word, but discretion prevents its use here). If you have questions about how big a unit you need, if one room's warmer than the others, if you want an opinion oas to scope of work on bids received, etc. just ask. Do visit www.askweldin.com, there's a lot of good information on sizing, ductwork, efficiency, as well as some techniques accomplished DIY-ers can use to troubleshoot and improve their H&AC. Finally, I want to thank all of the kind, serious people whom I meet here: I enjoy working with you. My wife says I'm "snarky" from time to time; as for you others, please use your imagination as to the responses swirling on the snarky side of my brain when I read your questions.
