Where is the cold air coming from in an air conditioner?
The cold air would enter the room with ceiling mounted vents located near the exterior wall, above a window and be collected by a hot air return located on an internal wall just below the top of the ceiling.
Where is the return duct used?
Most returns are mounted in the wall and use the channel created between two studs and the drywall as the return duct. No metal duct work is actually used. As this channel generally runs from the floor to the ceiling (less the 2 x 4 plates that are at the very top of the stud wall), it is only necessary to mark the location of the channel and cut an opening at the top of the wall, below the plates, the size of the grill, to allow the channel to pick-up air that is at the ceiling.

How are condenser and fan connected?
With a "split system," the condenser is outside the house and the fan-and-coil system are inside; they're connected to each other by pipes that carry refrigerant. If you have a forced-air furnace, the refrigerant pipes are connected to a cooling coil system fitted into the furnace air handler.
How to determine duct position?
The first step your contractor will take to determine the position of ducts is to draw a floor plan of the second floor and lay it over a floor plan of the first floor. "In 99 percent of homes," says Frank Scarangello, of Staten Island, New York-based Scaran Heating and Air Conditioning, "second-floor closets will give you access to locations for first-floor ceiling registers."
Why is an undersize compressor more expensive than an oversize compressor?
An oversize compressor also costs more to operate because it simply takes more electricity to run a bigger unit. And an oversize unit doesn't lower humidity effectively. That's because it cools the air so quickly that it shuts off before it has a chance to circulate the proper volume of air past the coils to extract the necessary moisture. The result is a room that doesn't seem as cool as the temperature indicates. In fact, the room can feel clammy and damp.
How much airflow can a new register grille improve?
Old register grilles with slits just 1/4 inch wide offer too much resistance to airflow; new grilles can improve airflow by 15 to 25 percent.

Do you need to change the thermostat to a heat only thermostat?
5. Your thermostat will need to be changed to a Heat/Cool thermostat if you have a heat only model. Also the wiring from your furnace to your thermostat needs to have at least ( 4 ) conductors to be able to utilize the new condenser. If you have only ( 2 ) conductors as is with most heat only systems, we will need to pull new wire to the furnace. If the existing thermostat wiring is stapled to the studs behind the sheet rock this may be a problem to be dealt with.
Does the efficiency of a house lower your monthly bill?
8. Someone needs to discuss all the different efficiencies that are available to you. The higher the efficiency, the lower your monthly electrical bill will be, however the up front costs go up as the efficiency gets higher. Obviously, a person selling the home in ( 2 ) years will probably not get the difference in cost back as would a person staying ( 5 ) years.
Do you need duct work for a central furnace?
