The one thing people hate to see this time of year is the monthly utility bill. When the temperature rises so does our air conditioning usage.  Here are a couple of suggestions to help keep costs down this summer: Replace that old air conditioner.

If you don’t already have one, get a programmable thermostat. With a programmable thermostat you can manage your entire building whether you are there or not.
