"Peter is a very knowledgeable and patient guy - he helped us understand our energy usage and even showed us how to read the usage of individual appliances used in our home. He also provided a full report on potential issues with specific windows, and had really good information about planning for future HVAC improvements. We feel so much better about our future home improvement projects after our home energy audit with Posert Energy!"

"Spectacular! I had solar installed and Trevor was super helpful with the process. He made all the complicated paperwork easy. Just like that we have solar and I'd never go back! Double thumbs up for Trevor!"

"Attic masters did a good job at my house by cleaning the ducts. I spoke to them prior and they were nice to me. they gave me several options and explain to me the difference between each one and they recommended me which one to choose. The work that they did was good and the people that did the actual work were very nice. I will hire them again.

"The entire process went smoothly. Begin with a system quote from Paul Sherer with a design layout, followed by a feasibility study of the roof and where the panels are to be installed. I have a metal tile roof and the previous solar vendor actually rejected the project. Slingshot first installed the 240v outlet and that took 2 people a whole day to complete, as my electric panel is at the other side of the house from the garage. The panel installation took another 2 days that included the interconnect, upgrading the breakers on the panel. The staff was professional, courteous and focus on doing the job right. Then the city inspection and followed by submitting the application to PG&E. The approval took only 3 days which was a pleasant surprise. Slingshot came out to install a CDD so I can monitor the performance and output of all 13 panels. Not only the project completely very smoothly and on time, the final price I paid is exactly what was quoted from day 1. Now that my electric car is here, I think I can recover the cost within 2 years."

"The cleaning job went very well. It was a job of many surprises( pokaman chips, matchbox size cars,of course legos etc. etc.etc.)! We moved to the house in 88,remodeled a few years later and then never cleaned them. The cleaning was a great check and all is well. In fact they stated that they weren't bad (considering). I was very happy they are in good condition.........................................."

"After a brief period of essential hammering in the attic and testing for air leakage, the work was done silently. The very pleasant installation crew was unobtrusive and efficient. I was amazed the "blowing in" process could be so quiet and clean. Not a drop of insulation escaped the attic."

Energy Efficiency Auditing FAQs, answered by experts

Services by electricians can quickly get expensive, but there are a few ways you can save money in the process:

  • Bundle multiple jobs done at the same time to save on trip fees or flat fees for individual projects.

  • Get at least three quotes for service to find the best deal.

  • Buy fixtures, switches, outlets, and other materials beforehand to avoid product markup.

  • If you feel comfortable with it, have an apprentice or journeyman complete the work under the supervision of a master electrician. These electricians in training tend to charge less per project.

There is no blanket figure for a residential home’s electrical load, since load varies by the size of the home, how many appliances are used, and the efficiency of their electrical systems. Typically, however, it’s safe to assume 40 to 60 amps is the average electrical load of a residential home. 

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. 

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.

Motion-sensor lights use one watt while on standby and five watts while turned on. They’re usually on for one hour over a 24-hour period, bringing the total wattage to about 28 watts per day. LED lights use around 6.5 to 8 watts while on. If you leave an LED light on all night, with night ranging from 10 to 14 hours, you’re looking at using 65 to 112 watts a night. You can minimally cut your wattage in half by switching to a motion-sensor light.
