Hello All,


We've decided to get a Keeprite Two Stage Variable Speed Mid-efficiency
gas furnace for our renovated 1500ft=B2 80 year old story and a half
bungalow and
have narrowed it down to two installers. Both have included duct
cleaning, re-routing of the basement cold air return to the floor, and
installation of the two fresh air ducts now required by the City of
Edmonton, Alberta, where we live. Both installers are members in good
standing with the BBB.

The difference between the two installers are system upgrades, and
therefore, price. Installer 1 quoted $3600 complete, including (1) a
radius return with 2 fins, and (2) a manually-operated 50% damper that
is put in position at Halloween and returned to open when the outside
water tap is turned back on. We tried to get the
price reduced by not including the damper, but Installer 1 believes
that the system should be installed complete to allow for the most
comfort in the house. Installer 2 quoted $2900 complete, but without a
radius return or damper. When asked if these would be useful upgrades,
Installer 2 disagreed.

I've done as much research as I could on radius returns and dampers,
including the forums posted by the knowledgeable folks on this site,
and understand that there are some benefits with these (radius return -

quieter, and more efficient use of filter; damper - keep too much cool
air from recirculating in the winter, especially with a variable speed
motor running constantly). In addition, we would like to go with
Installer 1, because he knew pretty much more than the other three
Installers who quoted combined and was easier to discuss things with.
However, we're not certain if the extra $700.00 for the two upgrades is

worth it.

Any commments would be greatly appreciated.=20

Regards, DL
