Case Study

Energy Saving Tip

Make sure to regularly change the air filters on your HVAC system (at least once per month). Old, clogged filters are far less efficient than new ones.


Electrical Appliance Safety

Always keep appliances clean, operating properly, and clear of obstructions. Unplug them when cleaning or repairing to avoid serious injury.
