I have been doing commercial HVAC service for quite a while but just recently just started working with a company that mainly tackles residential HVAC. I have been doing installs of high efficiency furnaces lately (Lennox). The Canadian government had a lot of incentives for higher efficiency equipment and people have been racing to make the deadline.
When installing plenums I have been taught to score the metal as it allows it to flex. Other then making sure everything fits nicely and using the appropriate S's and Drives what else can one do to eliminate pops and bangs? Is it normal to put canvas (vibration reducers) on all jobs? -return, supply, both? As well, the metal this company uses is 22 gauge - does this sound normal?
I am a little bit of a perfectionist and if I ever pick up my own jobs I would like to make sure the finished product hits the Refrigeration/HVAC bar, or as close too!
Any advice or knowledge would be appreciated.
