Ways to Save Your Money

The purchase price unit cost is but one aspect of the overall cost consideration. Operating costs, and, if needed, service costs, are important factors. Proper air conditioning maintenance can help your unit last decades.

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.
