"I've been with Posigen for about 7 years now and have always paid my bills on time!!!! As of Feb. 2022, I haven't been able to monitor my Solar Production because Posigen haven't updated their system to 5g Capability!!! I told them my payments are to be deferred until they update the system on their end!!! I spoke with a couple Reps that said your panels are producing what they should based on your production on your Electric Bill!!! I asked how can I know if I cant see the daily production to ensure the panels are producing what they should!!! They said take my word for it!!! I'm like that's very bogus to tell a faithful customer to take your word!!! Especially when the issue is not on their end!!! Now because of Non-Payments for 2 months of me not knowing what I'm producing since Feb, they're now threatening to shut my system off!!! Who treats a customer like this when the issue is on their end!!! Especially when that customer has been making faithful payments up into them not upgrading the system on their end!!! Can someone please recommend A good lawyer to stop them from interfering with system!!! Again, the issue is not on my end!!! I need help!!!!"

Energy Efficiency Auditing questions, answered by experts

Yes, pros suggest units with high EER ratings for energy savings.

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.

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

There are a few ways to reduce your electricity bills if you use window AC units to keep cool. Set the unit temperature at least 1 degree higher than it is currently to reduce costs. Keep the unit clean for it to run efficiently. You may want to hire a window AC specialist near you to inspect the unit once a year and keep it in tip-top shape.

A home energy audit costs about $420 on average, ranging from about $100 to $2,250 or more. Cost factors include the size of your home, the type of testing, and the thoroughness of the audit. A Level 1 walk-through inspection will cost between $150 and $200 for the auditor to point out inefficiencies in your home. On the other hand, a more thorough Level 3 audit with testing and a detailed report will cost about $900.
