"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."

Energy Efficiency Auditing FAQs, answered by experts

After you receive your audit and report, review the findings and determine which of the prescribed changes you want to make to improve your home’s energy efficiency. Start by contacting the type of professionals recommended by the auditor who can help you remedy the issues discovered during the audit. Prioritize the projects by urgency, importance, and budget. Then, gather estimates from several professionals, remembering to verify any necessary licensing and experience information.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

While you can perform many routine home maintenance jobs yourself, it’s often a good idea to bring pros in for certain tasks. HVAC maintenance, fireplace and chimney inspections, foundation repairs, and roof inspections and repairs should be handled by professionals who know what to look for and can safely perform repairs. You may also find it helpful to hire a local house cleaning service to help with deep cleaning.

It’s not recommended to turn off your breaker box in hopes of saving electricity. Breaker boxes were not designed to constantly be switched on and off. Therefore, turning off breakers unnecessarily can cause costly damage that outnumbers any energy savings. Only flip your breakers if absolutely necessary when troubleshooting an electrical issue.

String lights require electricity, but not an excessive amount, especially when compared to other lighting fixtures. LED rope lights, for instance, consume around one watt per foot. Running six or seven light strings simultaneously should only cost you around $10 to $15 each month. You can save even more money by remembering to turn off your lights during daylight hours.
