Cold End of the House

Just really looking at some options here. I have a 1300sq ranch that is on a slab. I have a down blowing furnace that feeds the vents that flow around outside perimeter of the house. I really hate living on a slab at times.

Well one end of the house is pretty warm, however the other end which is two bedrooms and a master bath just dont heat very well. Seems like the air is kind of cold by time it gets to that end of house. I also expanded that end of house by making bigger bedrooms and adding the master bath. I doubt i mess with it this year but would like to know options for adding heat to that end of the house.

Dad and I just put the new furnace and central air a couple years ago. I guess I could put another small furnace in the garage on that end and feed the bedrooms and also ability to heat the garage.

Maybe put some kind of wood stove in garage, electric baseboards...dunno.

I dont mind putting some money into getting it done or buying the equipment., more focused on the cost of heating and being efficient.

I just would like to get away from the space heaters. I also have a baby coming in July and will need more heat there next year.

Thanks for ideas

I live in northern indiana so it can get pretty cold

FOrced air requires not only properly sized supply ducts, but a proper return duct as well. Otherwise, it's like trying to blow air into a bottle...it will only hold so much. The return means there's a path to allow the incoming air some place to go.

If you don't have dampers in the ducts, you could probably add them. You'd want to force more air into the bedrooms by decreasing it some into the other areas with the dampers. Another alternative is an in-line booster fan to push more air into those rooms. This all assumes that the furnace you have has the capacity to acutally heat the house properly.

Was the new furnace sized for the additional space?
Does it run a lot?
Or does one area get warm before the other & it shuts off?

My last house I played around with the vents opening & closing to get the house balanced

I forget the actual size furnace,, i am think somewhere around 70-90,000 btu.
It is a Goodman and has been a trouble free furnace.

The furnace actually does seem to work quite a bit at times. But part of that i think is because the thermostat is close to a drafty laundry room that i need to close some drywall up on.

I dont keep my house very hot, around 65 degrees.
With the duct work built into the slab i feel limited on my options. Maybe I will adjust the vents some.

Currently there is one large cold air return thats in the hall way in the middle of the house. Could an additional cold air return in the back of the house help?

Thanks guys!

Cold air returns can possibly help. If your blower is running and you almost close the door of one of the cold bedrooms, does the door slam closed (assuming it isn't dragging on the carpet and the door swings freely)?

Think of it this way, to be able to get air somewhere, it has to flow, thus it needs a path out. The places with the least restrictions will get the most air. The longer the run and the more elbows, the more restrictions. If the ducts aren't insulated, the further it goes, the colder it gets, and you'll be heating (in your case) the slab and blowing colder air into that room, so more volume may be required.
