Solar-Powered Attic Fan Installation – Cool, Quiet, Cost-Cutting Comfort
Service Available in Los Gatos, San Jose, Almaden Valley, Saratoga, Campbell & Surrounding Areas
The California sun can turn your attic into an oven. Temperatures soar past 150°F, forcing your HVAC system to work harder and wear out faster. A solar-powered attic fan is a smart, low-maintenance upgrade that draws superheated air out of your attic—automatically, quietly, and without adding to your electric bill.
At Dollens Electric, we install code-compliant, high-performance attic ventilation systems that protect your home from excessive heat, moisture buildup, and sky-high cooling costs.

I was pleased when they briefly reviewed an installation manual to make sure they remembered exactly how the brand worked. It was obvious Joshua already knew how to make the installation but he doubled checked anyway. (I'm glad I'm not the only person who still refers to a manual.)
Call/use them; you won't be sorry.
Excellent communication and professional!
Highly recommend!
Jason seemed to know the possible cause for the problem when I told him that the parts of the house were losing power gradually, and he was right!! He came out on the same day and fixed the problem (burnt crimp in junction box in the garage) within an hour!! Excellent!
They went above board to make sure every thing was done to perfection !
They give an accurate read on what needs
to be done. They are a safety-first company
that shows up energetic & work...
They answered all our questions, let us know and talk through our options and didn't do any additional work without letting us know and approve the price difference for our requests, rather than telling us at the end of the job.
A+ work!
