HEATING AND COOLING SYSTEM MAINTENANCE TIPS

You wouldn’t drive your car 100,000 miles without changing the oil. The same logic holds true for your home comfort system. Regular HVAC preventative maintenance is the best way to ensure trouble-free operation and peak performance. Pre-season maintenance is also important. It can help to avoid a system failure in severe hot or cold weather when you need it most, and it can also keep your energy bill from getting out of control.

WHEN SHOULD I DO FURNACE MAINTENANCE?

The old adage is true: an ounce of prevention is worth a pound of cure. Below you’ll find our Preventative Maintenance Checklist, which is our proven method to keep your system running at peak performance and your home in constant comfort.

  • For a system that heats and cools: perform maintenance in the spring and fall
  • For cooling system maintenance only: perform maintenance at least once a year, before the cooling season
  • For furnace maintenance only: perform maintenance at least once a year, before the heating season.

HVAC PREVENTATIVE MAINTENANCE CHECKLIST

We provide priority service for their customers who have an annual maintenance or service agreement. Bi-annual preventative maintenance will ensure that your system runs as efficiently as possible. Your local dealer will perform the following tasks, depending on the unit:

  • Check manifold gas pressure
  • Check the pilot safety
  • Check blower alignment
  • Check and oil blower & motor
  • Clean and adjust the pilot
  • Check/adjust the main burner
  • Measure air flow & static pressure
  • Clean condensate drains
  • Clean condenser coils
  • Inspect heat exchanger
  • Check for gas/combustion leaks
  • Check draft
  • Check temperature settings
  • Check humidity setting
  • Clean or replace filters
  • Check for duct leakage
  • Check amps and voltages
  • Clean evaporator coil
  • Check controls operation
  • Test limit switch
  • Inspect wiring and connections
  • Check thermostat
  • Check refrigerant charge
  • Check oil pump pressure
  • Add algaecide tablets to drain pan
  • Tighten all electrical connections
  • Cycle check operations

HOW CAN I GET THE MOST OUT OF MY HVAC HEATING AND COOLING SYSTEMS?

HVACE systems are designed to provide optimal efficiency and comfort. Now it’s time to do the same to your home. Here are some things you can do around the house to optimize the operation of your system, as well as the comfort inside your home.

COOLING SYSTEM MAINTENANCE

  • Set the thermostat as high as comfort will permit.
  • Make sure attics are adequately ventilated to relieve heat buildup. If necessary, improve airflow by adding or enlarging vents.
  • When building a new house or renovating an old one, choose light-colored roof shingles to reflect more of the sun’s heat.
  • During moderate weather, don’t use the air conditioner unnecessarily.
  • Draw blinds or drapes to block the sunlight during the hottest part of the day.
  • Install awnings over windows exposed to direct sunlight.
  • In the cooling season, don’t run kitchen and bath exhaust fans longer than necessary.
  • Don’t place lamps, TV sets or other heat-producing devices beneath a wall-mounted thermostat. Rising heat from that equipment may cause the air conditioning system to overcool your house.

HEATING & FURNACE MAINTENANCE

  • Locate the thermostat on an inside wall away from windows and doors.
  • Set the thermostat as low as comfort permits. Each degree over 68°F can add 3% to the amount of energy needed for heating.
  • People generate heat. So lower the thermostat a degree or two when expecting a large group of guests.

INSULATION

  • Make sure your home is properly insulated. This is the single most important step in conserving energy. Thermal insulation should be specified in terms of thermal resistance (R-values). R-30 (10″) is recommended for ceilings, and R-11 (3-1/2”) for exterior walls and floors over unheated areas. In colder climates, consider additional insulation.
  • Infiltration of humid outside air is your heating and air conditioning system’s worst enemy—it could account for 15% to 30% of air conditioning energy requirements. Find the places where air can sneak into the home and plug them with caulking, weather-stripping or plastic. Also, weather-strip and caulk around all entrance doors and windows.
  • Cut heat transfer through your windows by 40% to 50% with double-glazing (two panes of glass separated by a sealed air space) and low-e glass.
  • Use wood- or metal-frame storm windows even if single-glazed windows are high quality. The extra layer of glass and the layer of still air will cut heat transfer considerably.
  • Install storm doors at all entrances to your house.
  • Keep all windows and doors closed.
  • Remember that by increasing the glass area, you increase the amount of heat added in summer and lost in winter.
  • Make sure fireplaces have tight-fitting dampers, which can be closed when the fireplace is not in use. Invest in a humidifier to conserve energy in winter. The air in your home won’t be as dry, so you stay comfortable at a lower temperature setting.
