understanding needed

[pjhdee]

hello,
moving from one older home to another....first home had ancient furnace and I thought it was bad...sheesh...this furnace on home we are moving to has another ancient...1979 Lennox 140btu that sucks....it has a suspected crack due to rust deposits....I know I need a new system but I'm leary of buying something that doesn't deliver the heat

house has finished basement and two above grade floors - total space for all that is about 4500 sq ft. old ductwork seems to be intact...house was built in '54....

not only do I not get much "oopmpf" up on the second floor, there are half the rooms on main floor where you can't feel heat until/unless you put a hand about 3 inches from vent. Even in the areas that DO heat...you can't feel anything if you stand 3 feet away...at least in my old house with it's ancient thing...you could stay 9 ft away and feel air....WARM air

it is not the filter, the blower is "working"....I have no idea what type of furnace would be best to get hot air (and a/c in summer) actually to come out in ALL rooms and allow you to actually FEEL warm air....

was my other house a fluke ??...was I just lucky with it??....we had to replace the motor on it, and the blower several times, but with easy repair, we still got warm air delivery....is the ability to feel warm air from the center of the room a thing of the past....do they not do that anymore??

I'm sooooooo very confused by everything I've been reading, I would dearly love some guidance as to what I need to concentrate on in order to get delivery everywhere....stages vs size of unit vs variable vs ????

I'm sure you guys have helped people like me, and often get tired of leading someone by the hand, but I am struggling financially, and I can't afford to head down the wrong path....your help is VERY much appreciated if you can grant me a little time...

manythanks
PJ

I would suggest having a system evaluation done to tell you were your deficiencies are. Then have a load calculation done to find out the equipment size and heat needed per room and necessary duct sizes. once you get that info system selection can be addressed.

the other house could have had a little more static pressure in the duct. More so than tis house. You need a load calculation done on the house you are in ow. Since you have so much square footage , I would ask about zoning the new system to help save on the power bill.

Might be time to have it checked by a service company.
May have a dirty A/C coil if it has central A/C also.

Before you do anything get a hold of your power company and see if they have any programs for a whole house evaluation which will include a blower door test, and also look at your hot water heater, lighting, appliance's thru out the house and based on house hold income they will replace upgrade any and all applainces for a small cost to you finaced by our local gov't :D The program we have in our state WI, most homeowners only have to pay 10% of the total cost to upgrade or replace your furnace, HWT, refrigerator, freezer, and will also insulate your house to building standards of today with R-49 in the attic and R-19 in the walls and if you have any crawl space they will insulate that as well. It's a good program if your power company participate it''s worth looking into, since this houe is a older one it may need alot of air sealing which is necessary to have done before you go and get bids on some new equipment. You can look on there webiste and if they particiapte there should be information on how to sign up.

Hmmm, must be nice living in Wisconsin. About the only deal we get in Connecticut right now is a lousy "up to" $500 rebate when installing a high-efficency heating plant.
