Updating duct work in older homes
The registers are unobtrusive discs placed around the perimeter of the ceiling, or high on the walls.
All retrofitted air-conditioning systems will require some degree of creative cutting and patching in walls, floors, and ceilings.
Air flow through your home is important for air quality.
In many homes, there will be only one return air vent situated near in a hallway for the bedrooms.
Once the ducts are no longer exposed to the heat of the attic, condensation decreases.
This made me realize that one bit of advice which I give during home inspections was not being followed by myself: improving my return air vent.
This pulls air from this part of the house, while the opposite end of the home remains stagnant.
This will heat the air returning to the air conditioning system, making the air conditioner work harder. I could have opened up my return plenum in the attic, and maybe dropped down some duct tubes which may have fit.Another alternative, known as high-velocity systems, use two-inch insulated air-supply tubing to deliver chilled air.This tubing can be snaked through existing walls and ceilings in an old home to deliver cool air where it is needed.Mini-splits offer an economical compromise: You can install cooling units in just one or two rooms, creating an oasis to retreat to during the dog days of summer.Consult a professional installer to choose an air-conditioning compressor that will allow you to expand a partial system at a later date.
