Heating/Air Conditioning

Heating

Your heating system is among the most modern manufactured today and should give you many,

many years of comfort with a minimum of attention. We recommend you read the manufacturer

owner’s manual for the proper maintenance and use instructions. The system was installed in

accordance with local building codes and the engineering design for your particular floor plan.

Adequacy of the system is determined by its ability to establish a temperature of 70 degrees as

measured in the center of the room, five feet above the floor.

Your heating system controls are precisely manufactured to exacting tolerances and engineered for

long years of carefree service. However, sometimes they need adjustment to keep them in peak

condition. Should adjustments be needed, call a trained professional or the original heating

contractor. See the subcontractor table for contact information. Your furnace is equipped with safety

controls in case of failure.

Your home’s cleanliness is enhanced by an efficient filter built into your furnace. You were shown its

location during your walk-through. Since it is designed to collect dust and dirt, it must be replaced at

regular intervals to maintain its efficiency. If hobbies, such as woodworking, create abnormal amounts

of dust, you may find it wise to replace filters as often as once a month. A clogged filter can slow air

flow and cause cold spots in your home. This is one of the most frequently overlooked details of

furnace care. To maintain peak efficiency, check your filter weekly for the first two months because it

may clog more frequently as it removes accumulated construction dust and loose carpet fibers.

Replacement is not difficult, but it may involve removing sheet-metal screws. New filters are widely

available. Make sure you check the size, which is usually printed along the filter/frame edge. For

convenience, buy filters by the box, usually a half dozen or dozen. Once you have lived in your new

home for some time, filter changes are recommended every 4-6 weeks.

The exact placement of heat ducts and resisters may vary slightly from their positions in the models.

Heat outlets (registers) and return air intakes function best when unobstructed. Do not block them

with furniture, rugs and draperies. Experiment with the adjustable registers in your home to establish

the best heat flow for your lifestyle. Generally, heat can be diminished in seldom-used or interior

rooms. However, this is a very individual matter and you will need to balance the system for your

family’s comfort.

The furnace will automatically turn on if the room temperature drops below the thermostat setting. A

point to remember is that, contrary to common belief, setting heating controls high does not make a

furnace heat faster.

Expansion or contraction of metal duct-work typically will result in some ticking or popping sounds, it

is not possible to eliminate these sounds.
