I do very little gas any more as I live in Heat Pump country now. Your
old furnace sounds way too big. The proper size is determined by doing
a "Load Calculation" that takes into account YOUR weather conditions,
window sizes type and directions, door area, wall area, ceiling area,
floor area and insulation levels for all those things. This involves
following ACCA Manual J, usually with a computer program.

The air flow should be measured to determine if your present ducts are
sized properly.

When I lived in Pennsylvania, we had no trouble twinning furnaces on
large houses. Some furnaces had twinning kits available.

Some furnaces don't need a twinning kit, just a single communication wire..


The thing about California law saying 125 K is max furnace size sounds
goofy, but, hey, you five in the goofiest state in the USA.

If you send me your email address with spaces around the "at" and "dot"
I will email you an article on high efficiency installations, which
should save you money in the long run.
