Heating and Air Conditioning

Furnace

• • Gas valve shut offs are located within the gas lines near the furnace and water heater
  • When the long part of the valve is in line with the pipe, it’s turned on
  • If you suspect you have a gas leak, leave home immediately and call the gas company
  • Change air filters monthly; shut off the unit before changing filter
  • Clear the intake and exhaust pipes, located outside near the ground level, of snow or other debris

Air-Conditioner

• • Keep outside unit from becoming clogged or dirty
  • Rinse unit occasionally with a garden hose; turn unit off before rinsing—switch is located inside the electrical box mounted on the side of the house near the air conditioning unit
  • Prior to the start of the air conditioning season:
  a) wait for outside temperature to exceed 60 degrees Fahrenheit
  b) check breaker box located in garage or basement to ensure breaker is on to the AC unit
  c) check electrical disconnect box on the exterior of the home near the air conditioner to ensure the switch in is the on position
  d) make sure furnace filter has been replaced in the last 30 days
  e) manually switch thermostat to “cool” and set temperature several degrees below room temperature
  f) monitor room temperature to ensure it achieves the thermostat setting
  • If unit does not operate due to lack of electrical power, contact electrical trade partner
  • If unit does not operate for any other reason, contact heating and cooling trade partner

Thermostat

• • Replace batteries once a year; remove front cover to replace batteries
  • The “Auto” blower-fan setting allows fan to run intermittently according to thermostat temperature
  • The “On” blower fan setting allows the fan to run continuously for constant air circulation

Care and Maintenance of New Heating and Air Conditioning System

• • Have your furnace inspected yearly by a qualified technician
  • Change or clean filter once a month
  • Keep combustible materials clear of furnace area
  • Visually inspect furnace for problems: holes in ductwork or flue, loose or unsecured wires, water leaks around condensation lines, etc.
  • Adjust floor registers according to conditions
  • Continuous fan operation helps balance temperatures in extreme hot and cold weather conditions
  • Expansion and contraction of duct work may cause minor popping sounds
  • Air conditioning works better if thermostat is left on and not turned off when leaving the house
  • Close drapes and blinds to reduce the amount of heat entering the home
  • Added humidifiers must maintain proper moister levels. Uncontrolled humidity causes condensation problems, warping of doors and woodwork and mold growth
  • Allow for an adequate volume of air flow around furnace and water heater
