THE HEATING AND COOLING SYSTEMS
Your heating and cooling system requires, at minimum, seasonal maintenance to be performed. This normally involves lubrication of motors and pulleys, cleaning of heat exchangers, and changing filters. Filters then must be changed frequently during the heavy use season. Refer to the manufacturers instructions for specific maintenance schedules.
Most homes require seasonal adjustments to the heating and cooling distribution system to balance the system. Normally, this involves opening the warm air registers in the lower levels and partially closing them in the upper levels during the heating season and reversing the process during the cooling season. Some systems are designed with zone dampering systems which may also be adjusted for proper balancing. With a little experimentation, you can balance the heat and cooling to the prime areas of your home and also save energy by reducing the supply to the lesser used areas. In addition, some systems are designed to allow continuous fan operation. Again, see the manufacturers instructions. Do not block registers and return ducts with furniture, drapes, etc.
If your heating, ventilating or air conditioning system should stop operating, check the following before requesting service.
Use a broom to remove snow and ice from heat pumps. Also refer to manufacturer's directions for regular cleaning instructions.
