Thermostats — The thermostat (usually located near the air return duct) helps to keep your home at an even temperature throughout. Individual room temperature may vary and can be regulated by adjusting the registers in the various rooms. The temperature may also vary between floors as warm air rises. If you have a second floor, it is likely to be warmer than a lower level. These variations in temperature within a home can be further minimized by leaving the furnace circulating fan on more consistently. If your home is heated by a warm air furnace or a heat pump your thermostat also may contain controls for converting from the cooling system to the heating system and vice versa. A recommended setting for a thermostat is 72 degrees for heating and 78 degrees for cooling.
The ASHRAE standard for heating states that the system shall be capable of producing an inside temperature of 70 degrees (heating) or 78 degrees (cooling) as measured in the center of each room at a height of 5 feet above the floor. IN THE CASE OF OUTSIDE TEMPERATURES EXCEEDING 95 DEGREES, A DIFFERENTIAL OF 15 DEGREES FROM THE OUTSIDE TEMPERATURE WILL BE MAINTAINED.
Register — The registers throughout your home help to regulate the flow of air and to maintain the desired temperature. By opening and closing the registers and dampers, you can determine the amount of cool or warm air that enters a room. Once the registers and dampers are adjusted, they, together with the thermostat, will maintain the temperature in your home. In addition to the air outlets, your home will have an air intake (return) register. None of these registers should ever be obstructed.
Filters — Your air conditioning system has an air filter to help keep the air in your home clean. For maximum efficiency, this filter should be replaced or cleaned regularly. Clogged filters can cause a unit to malfunction. The instruction manual for your system will tell you the location of the filter and how to clean and replace it.
Insulation — Your Watts Construction home has been designed to provide the proper insulation for our climate. Open doors, windows, fireplace flues and clogged filters are more often the cause of inadequate cooling or heating than deficient insulation. A lack of proper window treatments can also prevent the heating/cooling system from functioning properly. If you feel the insulation may be inadequate, though, you may contact your Watts Homes Service Department.
Inspection — A central air conditioning or heating system should be checked periodically by a professional repairman. See your instruction manual for the frequency of this care. (See also Electrical Service Entrance.)
Gas Furnace — Gas furnaces are normally automatic starts. If your heating unit is not an automatic start, your pilot light will have to be lighted manually at the start of the heating season, and turned off at the end of the heating season. Your furnace and vent stack should be inspected by a professional repairman at least once a year prior to the heating season.
Heat Pumps — Heat Pumps work to heat or cool your home. They transfer warm air from one location to another. As a result, the warm air delivered through your registers is cooler than the “heated air” produced by a gas or electric furnace. This gradual heat will keep the home comfortable. In many areas, heat pumps are equipped with an electrical back-up system to be activated in extremely cold weather.
Your new electrical or gas appliances are accompanied by instruction manuals and other papers. Look through them carefully. Remove, fill out and mail any return postcards necessary to record warranties. Keep a list of the authorized service agencies in the back of this booklet. Read all instructional literature so that you will know how to get the best from what you own, and so you will understand all appliance warranties. If an electrical appliance fails to work, before calling Watts Homes' appliance subcontractor be sure the appliance is plugged in and that no circuit breakers are tripped. If a gas appliance fails to work, check to see that the pilot light is lit. If you suspect a gas leak, turn off the main gas valve near the meter and call the utility company.
If your home has a pitched roof, the space between the ceiling and the roof may have louvered openings. Louvered openings should remain unobstructed all year round. If your home has soffit vents and/or ridge vents they should also be clear of debris. Ridge vents should be checked periodically to ensure they are secure and have not come loose in high winds.
