Q. Should I close the registers or ducts for areas of my home that I do not use on a regular basis?

A. You can close some vents in unused areas of the home but be aware that your insulation is the exterior walls, if you let the room get too warm or cool you will still need to overcome that in the adjoining rooms. Closing off too many vents may also cause issues with the furnace or air conditioner.

Q. How many years should I expect to get from a new furnace and air conditioning system?

A. The life expectancy of most systems is 12-15 years.
