Best Air Conditioning Repair in San Jose CA

Dalcon responded almost immediately on our Angie’s List project request, they scheduled us in the same week. The team of Chris and Josh worked efficiently and effectively over 2 days installing a new sub-panel, smart fan, 4-inset lights, moved a washer/dryer outlet, and improved our requested switches. They explained the work daily, had the right equipment/items, and were very polite and professional their entire project. Very impressed and will be using them for future electrical work for sure and will recommend them to community.

These guys were so great! They showed up on time and did amazing work. They were professional and super nice. I HIGHLY recommend them!

Everything was spot on with ARSEN Electric. Communication was stellar, the team was on time, did job efficiently and the rates were one of the best I could find. Can't go wrong with them.

Initial visit to determine the scope of work was great.
Communication was perfect.
Stayed on schedule as promised.
Indepth with options and choices so the scope of work is not just one option to choose from.

Installed a 220V outlet for an EV. Very competent and absolutely reliable. Showed up when he said he would, did great work. Knows his stuff and was able to make smart recommendations for best way to do the installation. Not the cheapest but not expensive and the work was impeccable.

Juan Galvan came out to diagnose issues with un even heat in rental unit. Made necessary adjustments to dampers and quickly updated me on tasks he performed. Appreciate his updates. Waiting to get feedback from tenants.

Specialized in smart homes and general electrical services, solves problems others can't.

Fantastic company, second job they’ve done for us and as before great work. Highly recommend.

Worked for this electrical contractor on their VMWare project...average at best. I have certainly worked for better, more organized contractors...other than efficient management, they also seemed to be having growing pains in that they did not have adequate amounts of functioning tools for their employees to use, cutting into production, requiring crews to share tools which other, better, contractors have plenty of. Would work for them again though if the opportunity presented itself.

Always have had Good service
Fast and lots of information

Highly suggested!!! They were able to get a service technician out the very following day after our AC stopped operating. The personnel provided us with several choices for fixing the problem and arrived on time. Ultimately, we decided to replace the complete system, and an install team could be ready the very following morning. Placed drop cloths all over the house and finished that day. Excellent value; couldn't be happier!

Valley just wrapped up an installation job, replacing our existing gas furnace with a new Trane heat pump and backup furnace. Great job.
