1. Conservative Operation of Your Central HVAC System.

This system is the number one energy consuming device you have in your home. It functions in all seasons of the year. In the summer it is your air conditioner; in the winter it is your heat source.  Here are some tips on how to operated this system in the most efficient manner possible.  These systems have a filter that is designed to keep dust particles and debris from collecting on the condensing coil, and fins of your HVAC system. It is very important to change or clean this filter every 30 days. If you neglect to change this filter or clean it, the results will be that your condensing coil and fins will become encrusted with dust; dirt and debris, like in the pictures to the right, reducing the heat transfer process, thereby increasing the energy need to operate the compressor for longer periods of time and turn on more frequently, to accomplish the necessary heat transfer process, thereby costing more money! If your condensing coil is already dirty, just follow the directions below to effectively clean your condensing coil and or fins properly and safely. 

An old hairbrush works well for brushing surface dirt and lint off the fins. Brush in the same direction as the slots between the fins so the bristles go between the fins. You can do a better job if you remove the guard grill, which protects the coil. Wear a dust mask to avoid breathing the dust. When you've finished brushing out as much of the dirt as you can, spray a heavy-duty household cleanser into the coils. Let the cleanser sit for five minutes. Then, direct a light spray from a garden hose at the coil's interior through the fan opening in the top of the unit. Use a gentle spray because a strong spray could bend the aluminum fins.

Follow these tips to save on energy costs

• Install these energy-efficient measures:
  • Replace and recycle your old refrigerator and purchase energy-efficient models. Units only 10 years old can use twice as much electricity as a new ENERGY STAR® labeled model.
  • Insulate ceilings to R-38 levels if your attic has less than R-19.
  • Caulk windows, doors and anywhere air leaks in or out. Do not caulk around water heater and furnace exhaust pipes.
  • Weatherstrip around windows and doors.
  • Wrap heating and cooling ducts with duct wrap, or use mastic sealant.
  • Install energy-saver shower heads.
• When buying new appliances, be sure to purchase energy-efficient ENERGY STAR® labeled models.
• If your old air conditioner is on its way out replace it with ENERGY STAR® labeled energy-efficient model.

            Set the water heater thermostat at 140 degrees or "normal." If you       have a dishwasher. Otherwise, set it at 120 degrees or "low." Check your dishwasher to see if you can use 120 degree water.
