Dave did an amazing job upgrading our Google Nest to the latest version. He did an awesome job installing, mounting, making sure we had the secondary sensor mounted and testing heating and AC when everything was done to make sure we were good to go. Great work and highly recommend!

Installed a 50amp NEMA 14-50 for me for my new EV. Very professional. They provided an itemized quote which included material pricing as well as labor costs. Dave was very communicative and provided updates on his arrival time. While here, he asked to see my charger cable so that he could properly align the plug. He cleaned up after himself, labeled the fuse box, and made sure that my EV was drawing the proper amperage. I would definitely recommend him if you’re looking for a fairly priced installation!

Details: No, there is no existing wiring • Install EV charger • 1 switch or outlet • Garage • Drywall • House

Dave responds very quickly and takes his time diagnose the problem to fix it at the root. We had a ceiling light fixture that was filled with water and couldn’t locate the leak. Dave opened up the ceiling minimally instead of tearing everything apart and worked with us to find out the history of leaks. We avoided a lot of unnecessary work and completed the job in time.

Details: Lights • 8 - 10 feet (standard ceiling) • House
