Energy Efficient Windows Save You Money on Energy Bills

Double Pane Windows and Triple Pane Windows

Our energy efficient replacement windows can save you money on your energy bills all year long.  In winter they keep the heat INSIDE your home so your furnace does not need to come on as often.  In summer they keep the heat on the OUTSIDE so your air conditioner does not need to work as hard.

25% Of Heat Loss is Old Windows & Doors

Old drafty windows and doors are a major source of heat loss in many homes.  Even if you have double pane windows but they are more than 25 years old, they do NOT have the energy efficiency standards that current windows have.


Installing quality energy efficient windows in your home is one of the few home improvement projects that can pay you back over time in the form of energy savings.

Our Windows Are Energy Star Rated Most Efficient

Harvey triple pane windows are Energy Star rated as the most energy efficient windows you can buy.  They do cost $100 more than double pane windows but if you plan to stay in your home a while, they may be worth the extra cost because of the extra energy saving benefits.

Double Pane Windows or Triple Pane Windows?

The current level of energy efficiency on double pane windows (as required by Massachusetts building code) is very good but triple pane windows give you an extra level of energy efficiency.
