Energy Efficiency Auditing questions, answered by experts

Typically, triple-pane windows made with krypton gas filling are the most energy efficient. A window’s frame, glass, design, and installation all affect its energy efficiency. These windows, in particular, are designed highly effectively in terms of their ability to insulate.

While you can perform many routine home maintenance jobs yourself, it’s often a good idea to bring pros in for certain tasks. HVAC maintenance, fireplace and chimney inspections, foundation repairs, and roof inspections and repairs should be handled by professionals who know what to look for and can safely perform repairs. You may also find it helpful to hire a local house cleaning service to help with deep cleaning.

HVAC systems use the most household electricity. This major and essential system is responsible for heating and cooling your home all year round. Since they operate for a significant amount during the day, it consumes more energy than other appliances. 

Gas fireplaces use either natural gas or propane—both of which will increase your energy expenses. On average, running a gas fireplace costs $400 to $640 per year; however, these costs can vary significantly depending on the fuel price in your area and the frequency of fireplace use. If you’re looking for a more energy-efficient option, consider switching to an electric fireplace.

Yes, energy-efficient options such as LEDs and solar-powered lights are available. These alternatives consume less electricity, resulting in lower utility costs. They are also more environmentally friendly due to their reduced carbon footprint and longer lifespan.
