"These guys are complete rip-offs!!! I got two other estimates for the replacement of a service cable. They were $500.00 and $700.00. Gen3's price... $4100.00 It took an inordinate amount of phone calls, texts, and emails to get an appointment for an estimate. Then they did not bother to send it to me. I had to call back for the estimate. These guys are the worst, most dishonest operators I have ever seen. They are 8 times more expensive than every one else. THINK ABOUT IT..... 800% more than the competition. Do not call these guys. OBVIOUSLY A DUMB GUY that thinks the public is STUPID. Don't trust them!!!!!! CROOKS"

Energy Efficiency Auditing questions, answered by experts

While many states require all new construction to undergo blower door tests, it’s not a requirement for existing homes. But in both cases, a blower test helps confirm that the contractor has sealed the exterior, that the type of ductwork installed is functioning properly, and that your home is as efficient as possible.

Yes, Tesla Powerwalls are worth the upfront costs, as you can recoup your investment within six to eight years. Plus, they provide peace of mind that you'll have power during a power outage, and, depending on the system you install, you can become energy-independent. While they may be more expensive than other solar power systems, they offer higher battery capacity and lifespan.

Depending on property size and audit scope, costs range from $200 to $600.

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.

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.
