Best Generators Maintenance in San Jose CA

Clifford was especially easy and great to work with. Very professional, got the job done relatively quickly (two bathroom fans replaced), couldn't have been any nicer.

Nick did a masterful job installing the conduit for my EV charging station. Careful, clean, friendly and great execution.

Pfeiffer Electric is a class act company! For many years have been using their services and they always deliver. The best thing about Pfeiffer Electric is their people. Every technician is knowledgeable, dedicated, hard working, honest and cares! Where do we find that nowadays...
We operate an institution with several buildings and many pieces of critical equipment. Pfeiffer Electric has always been there for us; whether it's installing and outlet, test panels, install new service, drawings and calculations or provide with complete site power backup and working through the night, you can count on them. Thanks!

Highly recommend Bahram and his team! Bahram is a great guy to work with, very trustworthy, friendly and responsive. He and his team are very experienced and good at what they do.

We wanted to get recessed lighting and some electrical work done in our house, and Bahram was recommended to us by a family friend. Bahram first visited and assessed the lighting and electrical work and gave useful tips and recommendations, and also told us what work was essential and what work was unnecessary. We decided on a date for the work, and Bahram was very accommodating and understanding when we had to adjust the dates slightly.

Bahram's team was fast and efficient, and they got the work done in a timely manner. They faced several challenges with the lighting due to the structure of the house/ceilings; however they quickly figured out the solutions and got all the lighting done. The quality of work is top-notch! Also, the pricing and quotes for all the work and parts were very reasonable.

Highly recommend ALTAP Electrical!

Brian installed a whole house backup Kohler 38 KW generator for our house.
I found him to be very professional who wants to do everything right, by the book. He is knowledgeable, hardworking and committed to doing a good job. He is also very polite, friendly and responsive.

I work graveyard shifts at my job and a huge part of my job is to make sure everything is running smoothly. Well the other night we had a storm and our power shut off but we have back up generators, however they haven't been used in so long they weren't working either and for our company that's a BAD thing cause we need our machines running all day all night. Luckly nite and ay power has ups backup system and came out to help us right away! They got to my site fast and just in time!

Incredibly professional and they do quality work! I’ll definitely be contacting them for our next project.
