Cold temperatures are here?


While winter in Northeast Florida isn’t nearly as bad as in other parts of the country, it still gets cold. Here are some small steps you can take to trim back energy use and save on utility bills.

Around your home or business:

Lighting: Use the new energy efficient bulbs to replace old style incandescent bulbs. And remember to turn off lights in unoccupied rooms.

Windows: Keep windows closed while heating the house. Also keep curtains closed during hours of extreme cold temperatures. If using venetian blinds, adjust them so that they reflect sun rays inward. Also, awning and jalousie windows should be closed as tight as possible to reduce air leaks. Open windows for natural ventilation only during mild weather.

Jacksonville Heating, Ventilation and Air Conditioning: Is typically the largest user of electricity in your home or business.

  • A good maintenance program will go a long way to enhancing the system’s efficiency and prolong the life of the HVAC unit. All Heating and Air Conditioningunits need to be serviced twice a year.
  • Replace Air Filters on a regular basis. A dirty filter restricts airflow and causes the unit to lose efficiency.
  • Throughout the house, it’s important to keep all air supply registers to all rooms open and the return air pathways free from obstructions (furniture). Also, doors should be kept open to any room that has a supply air register but no return air vent within the room.
  • Outside, it is wise to keep plants and other obstructions at least three feet away from the outside unit to prevent interference with air circulation.
  • Temperature settings play a significant role in a home’s energy consumption. For each degree you set the heating thermostat below 68 degrees, you will see up to a 4% savings per degree. Install a Programmable Thermostat to manage your temperature setting throughout the day and night.

Fans: Bathroom exhaust fans play an important role in increasing the comfort of your home and should run for approximately 20 minutes to effectively remove the excess humidity from the area.

Fireplace: Check to make sure the damper is closed when the fireplace is not in use.

In the kitchen: Do not use the oven or stove for heating the house. In general when cooking, using a microwave oven instead will be less expensive. A dishwasher uses the same amount of electricity whether it is fully loaded or only contains a few items. Therefore, run full loads to save energy. Clean off freezer and refrigerator coils every six months. The dust that accumulates on the coils reduces efficiency. Also, a full freezer runs less, even if that means filling up water jugs and freezing them. Place these containers beneath food so that they’re not in the way.

Hot Water: Turn off the water heater if you will be away from home for two or more days. The thermostat should be set between 120 and 140 degrees. The lower the setting, the more energy it will save.
