I have a bungalow style house with the garage/crawl space underneath. It's 963 sq. ft. but I don't have any duct work yet - it would be new with the heating unit. I live in the east bay of California so we're not freezing but I know that adding it would be a good investment and alot more comfortable.

Maybe they meant it would be installed it in the attic but I was told they'd cut the roof, place the heater in some sort of liner and attach the unit to the beams.

OK, so I'm green

but I'm trying to figure out why the heating unit needs to be on my roof. I had a floor furnace that quit early last year and am trying to move up to central heat/air. I have plenty of access room under the house but am being told that it would be better to go through the attic.
My concerns are 1) my house is 60 years old and already shakes when I run the washer/dryer -- what will it do with a heater running up above the living space 2) I have plaster walls and ceilings and cutting through them for vents seems to be asking for trouble 3) possible leak issues and the visual of a big heater on my roof. The AC would be a separate unit lcoated on ground level so why couldn't the heating unit go there too?

Any insight would be appreciated.

Megan,

I have no clue as to why you would need a furnace ( pkg. unit ) on your roof. I think you may be misunderstanding your contractor. If you have an accesible attic you can easily locate he fiurnace up there and vent it through the roof.

As far as noise, put in a good quality unit . Go variable speed and with proper duct design you'll have a hard time hearing it.

What style house do you have?

not so green

you do not have to have a pkg. unit on the roof, they can be placed on the ground. you have valid conserns. can your roof handle the additional weight? the sight, and noise of the unit. package units are made for commerical building, not homes. they have higher noise levels, and are lower in efficiency, than a residentcal split system. bottom line, your paying, get what YOU WANT. not what may be easier for the contractor.

right on the mark

We spend many hours perfecting our craft and your questions are valid.

Can you post your info IE area, house measurements and duct size that way we could offer you some sound advice on unit sizing.

With the cost of electric efficiency would be most important to me.

Ask questions, contact more than one contractor and if at all concerned contact local code office for help.
