Properly Set The Thermostat

The number one secret to keeping a low utility bill comes from a proper setting on your thermostat. It helps to set the thermostat at the highest summer setting or the lowest winter setting at which you are comfortable. You’ll find that typical settings are 76 degrees for summer cooling and 70 degrees for winter heating. When cooling, your operating costs increase from 3% to 8% for each degree your thermostat is lowered. When heating, your operating costs increase for each degree your thermostat is raised.

 

Clean Air Filters, Vents And Grilles

Check the air filter in your furnace or fan coil each month. A dirty filter will cause excessive wear on your furnace, air conditioner or heat pump. Replace your filter when necessary, or clean it if you have the reusable type. Make sure reusable filters are completely dry before reinstalled. A good rule of thumb is to check your filters when you get your utility bills, as it helps remind you to check your filters. This task is very simple and easy to complete yet is one of the most frequently ignored.

 

Likewise, arranging furniture and drapes so that all output vents and intake grills are free from obstruction reduces the cooling and heating load on your system.

 

Keep in mind that a blocked return grill can starve the blower unit of proper airflow. This, of course, will cause it to work inefficiently and cause unneeded repairs from wear and tear.

 

Utilize Direct Sunlight

Let the sun in during the winter. Keep the sun out during summer. In summer, direct sunlight increases the load on your cooling system. The use of window shades and awnings will reduce the amount of direct sunlight and lower the cooling load. In winter, direct sunlight reduces the load on your heating system.

 

Insulate Your Air Ducts

Ducts that pass through spaces in your home that have not been tempered such as crawlspaces, attics or basements can experience temperature changes more rapidly when not insulated. Be sure these air ducts are well insulated to maximize efficiency.

 

Keep An Air-Tight House

Ensure maximum retention of heated or cooled air by adding insulation to outside walls and to the attic. Seal cracks and use storm doors and/or insulated doors to prevent air leaks. However, this step can create other indoor air quality issues if your heating and cooling system are not properly sized – minimizing the fresh air in the home. Trapped air can become polluted as it is continually cycled through the system over and over again. A filtering or air treatment system may be required for an airtight house.

 

Alert

Failure to comply with all manufacturer instructions may result in fire or combustion that can cause property damage, serious injury or death. Before you perform any kind of maintenance, disconnect all electrical power to the unit before removing access panels; and be alert for sharp edges when handling parts or reaching into units. If performing maintenance not included in the list above, check with a Mr. Cool Heating and Air representative to determine if the service will void manufacturer warranties and guarantees. It is always better to be safe than sorry.
