heating and cooling


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 manufacturer’s 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 dampening 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 manufacturer’s 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.

  • Tripped circuit breaker.
  • The furnace or cooling unit switch (usually next to the appliance) is switched "off"
  • There is a blown fuse near the switch.
  • The thermostat is incorrectly set to "off" or wrong setting..."heating or cooling."
  • The pilot light is out.

During normal operation of your furnace, the furnace filter removes dust particles from the air circulating through the furnace.

  • A clogged furnace filter will restrict air flow and cause undue hardship on the furnace motor.
  • It is important that you clean or replace the furnace filter every 30 days during the winter months.
  • Also refer to manufacturer's directions for regular cleaning instructions.
