I'm about to get a final price for a new oil furnace.

Need I make sure that they will install an oil filter in the line from
the in-the-basement oil tank? * For the last 31 years, since the house
was new, there hasn't been one, and that doesn't seem to have caused
any problems. *They always leave the old oil nozzle behind and it's
never dirty on the surface, plus I never had to get service because
the nozzle was clogged. *(they have their own built in filters)

But I know, at least I think, some people have oil filters.

Is there any other special or needed request I should make (so that I
don't find out later I needed something but it wasn't included) for
the oil furnace or the Air Conditioning.

Something they might want extra money for it after they casually cause
me to think of it during the install? *(Do you want the
rodent-protected air-intake?, for example.)

No one bolts the compressor unit to the cement pad, right?** *I don't
need a new cement pad do I if the current one isn't cracked?

The reason for filters in the oil line is that if you have a steel oil
tank, condensation water in the bottom of the tank causes rust which
might find it's way into and block small orifices or damage the oil
pump. (If it is a pressure jet burner). If your oil tank is plastic,
it's less important but still desireable, I don't know if your
delivery tankers in America have filters on the oll delivery line.
Your oil tank should be installed with a slight slope and two outlets,
one at the bottom at each end . The lower one is to drain any
condensation, the upper is for the oil to your furnace. You should
check for condensation every couple of months or so, depending on your
climate.

Small refrigeration compressors usually freestand on rubber feet. If
your's has moved, it probably indicates that you cement base is not
level & it's run away downhill over the years.
