I bought a house where the previous owners had begin converting the garage into a bedroom. I finished it (hired a carpenter). The only problem has be heating and cooling it. I had the duct work checked and the previous owners have laid it but hadn't connected it. We connected it and that helped some but we still had to use a space oven to keep it warm ample. Summer is worse. Can't get a space "cooler" to put in in attendance :-)

My thinking was to put in another vent but two electricians own told me that they didn't think that would help. The outside wall doesn't hold insulation in it so I'm looking into getting insulation blown into it but I've been told that that will probably singular help it a little. One item I've thought about is that the wall between it and the living room does have insulation surrounded by it (the rolled kind), like an outside wall does. So, could that be hurting our attempts to heat and cool it?

Any suggestions would be appreciated.
do you have an air return queue for that heating duct? if air can't set off the room it won't come in,plug the new duct into the the return strip of the furnace,if you still can't get enough flow you might put in a fan to push the air down the return vein.. for cooling cut a hole in the wall and install a window room ac.i would patently insulate ,how about the floor is it a concrete slab ,perhaps put contained by an insulated floor ,put down a vapor barrier and a thick hearth rug backing and then a glutinous carpet,or go expensive put down a vapor barricade stud it out like a wall fill next to insulation,cover with flooring then hearth rug,tile whatever.tom


Insulate the outside walls and ceiling. Make sure there is a vapor barrier too. Put within a ceiling fan to make sure the heavens circulates and keep the door open. It probably would give support to to take the insulation down between the new room and the house. how heaps ducts/vents do u have in in that? what is the size of the garage?.just guessing on ur garage size , u would need 4 8" vent in there...did u check to see if the owner have put in a return in the room.u have need of a return in there also...make the addition of ceiling fan.and check to see if ur unit can touch the extra runs he made to the garage...

Answers:    this is comfortable to answer, first this room was never intended to be a living space, insulation was never that righteous in garages. so here is a cple of things you need to do:
1. put in more insulation: walls, ceiling atleast an
R-19 value
2. vapor barrier the walls
3. telephone a licensed hvac contractor in your area, at hand are many solutions available, from zoning, re-design of ductwork, etc

the situation your having is simple, the thermostat isnt reading that rooms warmth, only the rest of the house, problem is there is a warmth differance from this room and the rest of the house.

i recommend you call a contractor, have him execute a proper load calculation on the entire home, this will breed sure the current system is sized properly for your entire home ( new bedroom included)
this will also give him an opportunity to check the duct system, to brand name sure it is sized and installed properly. be sure to explain the entire situation and problems you are having, the more info you can give, the more he can lend a hand you

when you call, explain your problem, and tell them you inevitability a consultation
