Tune up your office's heating, ventilating, and air conditioning system

Heating and cooling typically account for 25% of an office building's energy use. Save energy and money by tuning up your heating, ventilating, and air conditioning system annually. Change or clean filters every month during peak cooling or heating seasons. Make sure that areas in front of vents are clear. As much as 25% more energy is required to distribute air if your vents are blocked.
