Mayfield Electric & Water Systems

• An efficient heating and cooling system. Central air conditioners, heat pumps and room air conditioners should have a Seasonal Energy Efficiency Ratio (SEER) of 12 or higher. For room air conditioners, the energy efficiency ratio (EER) should be 10 or higher. The higher the SEER/EER, the cheaper the unit will be to operate. Gas furnaces should be rated at a minimum of 80% Annual Fuel Utilization Efficiency (AFUE).

• A heat pump for year-round heating and cooling. These all-in-one systems heat in the winter and cool in the summer. In the summer, a heat pump is a high-efficiency air conditioner. In the winter, it's one of the best heating systems you can own.

• Duct work that is free of leaks and well insulated. The ducts that move heated and cooled air through your house should be carefully taped and wrapped with at least two inches of insulation.

• Correctly insulating and sealing your home. The harder your heating and air conditioning system must work to overcome air leaks, the higher your bills will be. Even simple steps, such as closing a fireplace damper or caulking around plumbing pipes, can save you money on your electric bill.

• Regular maintenance. Change air filters monthly and have your heating and air conditioning system inspected by a professional at least once a year. Also, make sure your outdoor unit stays free of grass clippings and other obstructions. A dirty or clogged condenser costs more to operate.
