Preventative Maintenance Info

Always change your furnace filters regularly. Dirty filters cause the unit to work harder to push the warm air through the filter, causing your unit to run less than efficiently and possibly break down.

Summer Cooling Information

Set your thermostat as high as comfortably possible in the summer. The less difference between the indoor and outdoor temperatures, the lower your overall cooling bill will be.
