An Energy Star Air Conditioner or Heating System will save Energy and Money. Choose Wisley and Save Money!





As much as half of the energy used in your home goes to operate your Air Conditioner and Heating system. So making smart decisions about your home's heating, ventilating, and Air Conditioner(HVAC) system can have a big effect on your utility bills — and your comfort. Take these steps to increase the Energy Efficient operation of your heating and cooling system. Change your air filter regularly Check your filter every month, especially during heavy use months (winter and summer). If the filter looks dirty after a month, change it. At a minimum, change the filter every 3 months. A dirty filter will slow down air flow and make the system work harder to keep you warm or cool — wasting energy. A clean filter will also prevent dust and dirt from building up in the system — leading to expensive maintenance and/or early system failure.

Remember to choose the best equipment that is properly sized for your home and the right contractor to install it to manufacturers specifications. If you choose Energy Star equipment and demand your contractor follow their installation requirements you will receive the best system for the money and long term savings and reliability.

Tune up your Air Conditioner and Heating system equipment yearly Just as a tune-up for your car can improve your gas mileage, a yearly tune-up of your heating and cooling system can improve efficiency and comfort.

If your HVAC system is old or you’re building a new home be sure to pick an Energy Star system and installation of your new equipment. Replacing your old heating and cooling equipment with new, energy-efficient models is a great start to going green and saving energy which saves you money. But to make sure that you get the best performance, the new equipment must be properly installed. In fact, improper installation can reduce system efficiency by up to 30 percent — costing you more on your utility bills and possibly shortening the equipment's life. Once your equipment is in place performing well routine maintenance will ensure your best return and operation.

Maintenance Checklist

Maintain your equipment to prevent future problems and unwanted costs.

Keep your cooling and heating system at peak performance by having a contractor do annual pre-season check-ups.

Contractors get busy once summer and winter come, so it's best to check the cooling system in the spring and the heating system in the fall. To remember, you might plan the check-ups around the time changes in the spring and fall.

A typical maintenance check-up should include the following. Check thermostat settings to ensure the cooling and heating system keeps you comfortable when you are home and saves energy while you are away.

Tighten all electrical connections and measure voltage and current on motors. Faulty electrical connections can cause unsafe operation of your system and reduce the life of major components.

Lubricate all moving parts. Parts that lack lubrication cause friction in motors and increases the amount of electricity you use.

Check and inspect the condensate drain in your central air conditioner, furnace and/or heat pump (when in cooling mode). A plugged drain can cause water damage in the house and affect indoor humidity levels.

Check controls of the system to ensure proper and safe operation. Check the starting cycle of the equipment to assure the system starts, operates, and shuts off properly. Cooling Specific

Clean evaporator and condenser air conditioning coils. Dirty coils reduce the system's ability to cool your home and cause the system to run longer, increasing energy costs and reducing the life of the equipment.

Check your central air conditioners refrigerant level and adjust if necessary. Too much or too little refrigerant will make your system less efficient increasing energy costs and reducing the life of the equipment.

Clean and adjust blower components to provide proper system airflow for greater comfort levels. Airflow problems can reduce your system's efficiency by up to 15 percent.

Heating Specific

Check all gas (or oil) connections, gas pressure, burner combustion and heat exchanger. Improperly operating gas (or oil) connections are a fire hazard and can contribute to health problems. A dirty burner or cracked heat exchanger causes improper burner operation. Either can cause the equipment to operate less safely and efficiently.

Actions To Do Yourself

Inspect, clean, or change air filters once a month in your central air conditioner, furnace, and/or heat pump. Your contractor can show you how to do this. A dirty filter can increase energy costs and damage your equipment, leading to early failure. A programmable thermostat is ideal for people who are away from home during set periods of time throughout the week. Through proper use of pre-programmed settings, a programmable thermostat can save you about $180 every year in energy costs.

Seal your heating and cooling ducts Ducts that move air to-and-from a forced air furnace, central air conditioner, or heat pump are often big energy wasters. Sealing and insulating ducts can improve the efficiency of your heating and cooling system by as much as 20 percent — and sometimes much more.

Focus first on sealing ducts that run through the attic, crawlspace, unheated basement, or garage. Use duct sealant (mastic) or metal-backed (foil) tape to seal the seams and connections of ducts. After sealing the ducts in those spaces, wrap them in insulation to keep them from getting hot in the summer or cold in the winter.

Next, look to seal any other ducts that you can access in the heated or cooled part of the house.

There are professional duct sealing companies that use computer technology and state of the art sealing techniques for your best results I recommend you look into one of these services in your area. This system can reduce air loss by as much as 60%

Consider installing ENERGY STAR qualified heating and cooling equipment if your HVAC equipment is more than 10 years old or not keeping your house comfortable, have it evaluated by a professional HVAC contractor. If it is not performing efficiently or it needs upgrading, consider replacing it with a unit that has earned the ENERGY STAR.

Depending on where you live, replacing your old heating and cooling equipment with ENERGY STAR qualified equipment can cut your annual energy bill by nearly $200.
