Energy Efficiency Auditing FAQs, answered by experts

Leaving lights on raises the electric bill, but not as much as having high-wattage light bulbs. The best way to save on electric costs is to swap your light bulbs to LED or CFL bulbs that use far fewer watts. You can also use smart lights and light switches to control usage via a smartphone or voice-controlled device.

Expert installation optimizes insulation properties, cutting energy costs and enhancing home comfort year-round.

Costs depend on the property size, audit complexity, and whether additional testing (e.g., blower door) is included.

A good SEER rating for an HVAC system is typically between 15 and 20. However, minimum requirements vary by location; HVAC systems in northern states must have at least a 14 SEER rating, while those in southern states need a minimum of 15. For the highest possible efficiency, look for units with a SEER rating of 21 or higher. It's important to remember that a SEER rating represents the maximum efficiency a unit can achieve, not the level at which it will operate at all times.

Motion-sensor lights use one watt while on standby and five watts while turned on. They’re usually on for one hour over a 24-hour period, bringing the total wattage to about 28 watts per day. LED lights use around 6.5 to 8 watts while on. If you leave an LED light on all night, with night ranging from 10 to 14 hours, you’re looking at using 65 to 112 watts a night. You can minimally cut your wattage in half by switching to a motion-sensor light.
