Heating & Cooling

Heating and cooling represents the highest area of energy usage in the average home.  There are a few basic things you can do below to improve the efficiency of your heating and cooling system.

What can you do about it?

Adjust thermostat.

In the winter set the thermostat to 68°F while you're awake and set it lower while you're asleep or away from home. By turning your thermostat back for 8 hours, you can save 5% to 15% a year on your heating bill. In the summer, you can follow the same strategy with central air conditioning by lowering the thermostat setting to 78°F (26°C) only when you are at home and need cooling.


Repair leaky ducts.

Leaky ducts account for a huge loss of energy.  The average home loses 40% of heated or cooled air due to improper duct work.  That means for every $100 you’re spending on heating and cooling, you are wasting $40.  Common issues are holes/leaks, improper materials or insulation of ducts, too many twists and turns, and gaps in the system.


Install a programmable thermostat.

Monitor heating and cooling times by purchasing a programmable thermostat. This is an inexpensive way of better controlling the temperature of your home. Although thermostats can be adjusted manually, programmable thermostats will avoid any discomfort by returning temperatures to normal before you wake or return home.


Change air filters regularly. 

A dirty air filter makes your heating/cooling system 25% less efficient.  Changing out the filter will not only improve the efficiency of you heating and cooling system, but will also improve the quality of air you breathe in your home.  


Upgrade your heating and cooling system to an ENERGY STAR rated model.

Upgrading your heating and cooling system to an ENERGY STAR model can save you up to 44% of energy compared to standard models.
