Energy Efficiency Questions

Top strategies: schedule regular maintenance, replace filters monthly, seal air leaks around windows and doors, add insulation, use a programmable thermostat, keep vents unblocked, close blinds on hot days, and upgrade to high-efficiency equipment when replacing. Small changes add up to significant savings.

Heat pumps are the most efficient heating option, delivering 2-3 units of heat per unit of electricity (200-300% efficient). Geothermal heat pumps achieve even higher efficiency. For furnaces, condensing gas models reach 98% AFUE. The best choice depends on your climate, fuel costs, and existing infrastructure.

Mini-splits can be 25-30% more efficient than central systems because they avoid duct losses (which can account for 25-30% of energy use in central systems). They also allow zone control, so you only condition occupied spaces. They're especially efficient for heating and cooling specific rooms.

Closing vents actually wastes energy and can damage your system. Central HVAC systems are sized for your whole home—closing vents increases duct pressure, forces the blower to work harder, can cause leaks, and may freeze AC coils. Use a zoned system or mini-splits for room-by-room control.
