We called in our plumbing/heating/gas fitting self proclaimed god for our present renovation. Upon his expert inspection it came apparent that the furnace was original – 1941 vintage, and apparently back in those days the home owner could fit them. The furnace was probably running at 40% efficiency. Couple that with 3mm single pane windows and some poor insulation you’ve got yourself a hell of a hydro bill. We also brought in a ducting subcontractor and well to put it mildly he’s mystified. He’s going to have to spend some time figuring it all out, what is supply and what is cold air return by playing a radio at one end and hopefully hearing it at the other end. There could be a chance that in the present set up there isn’t enough cold air return points in the system. We’ll come back to this post when we know more.
She’s a big un eh?
