I didn't get any traction on this in the pro forum so I wanted to see if I could get any feedback tools section since this is along the lines of tool - more like materials:
I'm helping put together some PM contracts for a small chain restaurant operation and would like to create some specifications for parts the HVAC contractors use. We suspect we have some using quality stuff and others using the cheapest thing they can buy. Problem is I don't really know which is which. All RTUs are 5 - 7.5 tons.
So, air filters seem easy enough. Specify pleated, MERV 8 filters. Though I would like advice on what materials are better than others - cotton vs. synthetic. Is pleated, MERV 8 the correct specification for a restaurant's 5 - 7.5 ton unit?
I don't know what to specify for belts. I know cogged vs. standard, and would like to specify cogged, but with the small units the energy savings is small. I'm not sure if it is worth it and whether the contracts would push back on that. One has already told me they are not a stock item and they would have to order them. So, are there different types/qualities of the standard belts? I'm sure there are varying qualities, what makes one better than the other? Different materials? I'm looking for general stuff where I could state "contractor will use xxxxxx v-belts with a rating of xxxx" whether the x's are a material or rating or type... What makes a premium belt or filter premium?
Any guidance is very much appreciated.
