I have recently purchased a 1975 singlewide mobile home (2x4
construction with aluminum panel siding). The unit has a Coleman
electric furnace (no heat pump), storm windows and rather minimal
insulation throughout. I am trying to decide what improvements
(if any) would be justified. The trailer is located in the
Seattle area where temperatures rarely get below the high 20's
and air conditioning is considered to be a (rarely necessary)
luxury.

A heat pump is probably out of the question due to cost.

In the long run it may be the cheapest solution, especially in your
area. You also gain a very effiecent air conditioner.


I am considering re-insulating the floor, removing the original
"rodent barrier" and R-7 (more/less) insulation, replacing same
with R-19 stuffed between joists plus duct insulation, etc. I've
figured the cost of materials at around $400.

Seems a little high for materials, but it may be right. If done right
it is a good idea.


I've also been told (but haven't confirmed) that it would be
possible to add "blown in" insulation to the ceiling for around
$300. I haven't determined the current insulation up there, but
it is probably R-13 or R-19.

If you are up to 19 now I would not bother, I doubt if you can get it up
far from there.


I'm planning to replace both doors (hollow core) with current
R-5 (or better) models.

I have also thought about looking at a NEW electric furnace/air
handler. However, I've received mixed reviews as to whether newer
units are really any more efficient than the originals. (However,
a new one would likely be QUIETER.)

No help here. Any direct electirc (not a heat pump) will be exactly the
same efficency, 100% Heat pumps can go over 100% and in your area they will
operate over 100% almost all the time, often far over.


I would greatly appreciate comments on these issues or any other
suggestions that might yield improvement. Do-it-yourself
approaches are most likely to be implemented. grin

Thanks!
