Heating

• Experiment to determine how long it takes for your space to heat up or cool down. Time your thermostat to turn on shortly before people arrive and to shut off one half-hour before they leave, so you keep your premises warm only when it's full of employees.
• Install ceiling and wall insulation.
• Reduce heating in areas that need less warmth, such as storerooms or areas where heavy physical work is performed. Reduce heating at holiday times, weekends and other times when the building is empty.
• Make sure thermostats are set correctly and properly located — for example, don't put them in parts of the room that are draughty or particularly cold or warm.
• Don't put furniture in front of radiators because that will reduce their output.
• Turn pilots off in summer or use intermittent ignition.
• Ensure heating and cooling cannot operate at the same time.
• Install locking covers on your thermostats to prevent people changing the temperature settings.
• Perform scheduled maintenance on units including cleaning condenser coils, replacing air filters regularly, and checking ducts and pipe insulation for damage.
