Energy Efficiency Auditing questions, answered by experts

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. 

Costs depend on pipe length, accessibility, and whether additional services are required.

Yes, installing an attic fan can help lower your electric bill—particularly if you live in a hot and humid region. By replacing hot and stuffy air with cooler air, these fans help regulate the temperature in your attic and the rest of your home, taking some of the pressure off of your air conditioner.

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.

While some aspects of an appraisal, such as comparable properties nearby, are out of your control, there are several steps you can take to potentially increase your home's value. Make any necessary repairs and upgrades before the appraiser's visit, as they can only value what is currently part of the home, not its potential. Examples include renovating older areas, updating landscaping to boost curb appeal, and staging your home. You can also provide the appraiser with the cost of recent upgrades, which may increase your home's value by about 50% or more of what you paid for those improvements.
