"Jonathan handled our Home Energy Audit and did an excellent job. He was on time, did exactly what he said he would do, and was thorough in his work. I appreciated his relational approach to Eco Three's work. He clearly communicated with me throughout the process and offered solutions for our home moving forward. I would recommend Eco Three to others in my neighborhood.

Energy Efficiency Auditing FAQs, answered by experts

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

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

R-value is calculated by dividing the thickness of an insulation material by its thermal conductivity. The material's composition and density influence thermal conductivity. Materials with lower conductivity values provide better insulation. The higher the R-value, the better the material is at insulating, helping homeowners select insulation that meets the energy needs of their climate and home layout.

Smart home upgrades can be worth the money. Several upgrades, including smart thermostats and ceiling fans, can help reduce your energy bills. Others make life more convenient, freeing up your time to do what you love (or get more work done). And some smart home upgrades, such as entertainment systems, simply make life more enjoyable. All are worthy causes.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.
