An Investment Your heating and air conditioning typically account for more than 40% of your home´s annual energy costs.  In effect, your indoor comfort system is the only part of your home that can actually pay for itself while also providing the added benefits of increased comfort and quieter operation. Seer Rating And Energy Costs For every $100 you spend to cool your home using a 10 SEER (Seasonal Energy Efficiency Rating) system, you would spend much less using a system of 13 SEER or higher.  For example, if your annual cooling costs were $1,000 with a 10 SEER system, they could be reduced to $710 with a 14 SEER system. Maintain Proper Humidity When cooling during the warm humid months, you will feel more comfortable at a higher temperature if the humidity level in your home is kept between 40 and 60%.  This will reduce the load on your equipment and can save 10 to 15% in cooling costs. Condition Only Occupied Rooms Zoning or Programmable Thermostats can control your equipment according to your family´s lifestyle and daily occupancy schedule.  This allows you to eliminate the wasted energy of conditioning areas in your home that are unused or unoccupied. Keep Equipment Clean Regularly scheduled professional maintenance is also crucial to maintaining your system´s maximum efficiency.  Keeping your equipment clean by using an Electronic or Mechanical Air Cleaner will help maintain your system’s optimum performance too.
