"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.

"Can never go wrong with them"

"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."

"I was mind blown with his service. I talked to 6 solar businesses before, all of them has poor customer service and the price was too high. The service was beyond amazing. It was great. The process went very smooth. One of the best experience I ever had in contacting a business. That young man was really polite. I was really happy with his service."
