I have a coleman HVAC system and inside the house, coming out of the base of the unit was a pipe or vent that went straight to the roof. I believe this was an intake. The last maintenance person removed the pipe and taped off the opening saying that it wasn't necessary. To this uneducated person, that seems reasonable. His reasoning was during 90 degree days, why pull in 90 degree air from the outside and mix it, unfiltered, with the ac air. Ditto trying to heat in the 30 degree nights of winter. However, this pipe is there for a reason. Can someone tell me the implictions of removing this pipe and taping off the opening? Thank you.

This is a regular home?? Old or new?
Was this tied into the return duct work if the system?ou
If this was tied into the return duct work, this is a fresh air vent for your home.. On newer homes, the fresh is needed to make up air that is lost up the flue pipe (not knowing that type of heating you have), exhaust fans, and dryer.
It's not worth having it hooked up into a system.. he did make a good point about the temp extrem.. (Mn winter nights may get down to -25, that's alot of cold air to heat up again)
I have mine dropped down to the floor, then did a goose neck back up. That way there is not a large amount of cold air getting "spilled" into the laundry room floor.
So, don't cap that off if you need fresh air made up when all the window is closed.

Jay,
Yes, it was definitely a fresh air duct. It is a newer manufactured home (a year 2000 tripple wide). Being a manufactured home, we get plenty of fresh air through the many "leaks" in the house... Ugh.
Thank you for the reply. His reasoning did make sense to me, but I was worried that it might be pulling too much air through the coils or somehow harming the system mechanically. I'm glad it's ok as is. I'll leave it sealed. Thanks again.
