My utility bills seem unusually high
Check for signs: Possible cause: Possible remedy:
Consider whether you have new appliances (e.g. a hot tub or pool heater) that might be using lots of power. -- It may not be your heating and cooling system that's raising your bills.
Check to see if your local utility company had a recent rate increase. -- It may not be your heating and cooling system that's raising your bills.
Check to see that your system is cycling constantly.
If your system IS cycling constantly, and IS reaching its set point... This usually means that your system's working fine, but your local temperatures are constantly in the extreme, so your system's working extra hard to meet that set point.
Check to see that your thermostat is reaching its set value. If your system IS cycling constantly, but ISN'T reaching its set point... Contact Denson HVAC
