No, it doesn't insulate very well either thermally or electrically.
well depending on the type of building and also depending on how old the building possibly is could depend on weather or not you would need to insulate the pipes.
Yes cooling requires larger duct work. Typically you would size the duct work for the cooling system and heat will work fine as well
If your apartment does not have duct work, the owner of the building has not had it installed. Perhaps they felt it would be too costly to install, or perhaps they are simply not interested in or see a need for duct work.
For round duct, measure from one side to the other, and you have the diameter.
there is no prefix of insulate because the root word is insulate
I need to get some duct cleaning work done in an office building I just bought. Can I do this myself or do you recommend a specialist?
Diffrent color duct tape could work or sparkles.
Do I need special tools for hood duct cleaning? Is regular duct cleaning type equipment satisfactory?
The answer is quite simple, your duct work is not insulated somewhere. What is happening is the really cold air is blowing through the duct work and where it is not insulated, its causing condensation to form. It then builds up and starts dripping. You can either go to a hardware store and ask them for duct wrap or just buy a roll of fiberglass insulation and wrap it around and secure with duct tape.
I work really long hours but need to get my ducts clean. How can I find someone who does residential duct cleaning in the evenings?
I think would not work..
