I wanted to check all 5 terms to cover Promax services to also include work quality and professionalism. Max was awesome on all levels. He was prompt for the 2 days it took him to complete the installation of 3 smart light switches that required him to rewire all 3 switches. He stayed late to get it done right and even changed out another switch in our garage that did not work after he changed the 3 switches and did not charge us for this. I will certainly use him again. Highly recommend him!

Details: Upgrade wiring, fixture, or equipment • Lights • Switches • 8 - 10 feet (standard ceiling) • House

I recently had a garbage disposal installed by Promax Service Group, and I couldn’t be happier with the experience! From start to finish, their team was professional, efficient, and highly knowledgeable. Scheduling the service was easy, and they arrived on time, fully prepared for the job. The installation itself was quick and seamless, with great attention to detail. They ensured everything was working perfectly before leaving and even took the time to explain proper maintenance to extend the lifespan of my new disposal. Overall, I highly recommend Promax Service Group for their outstanding service, expertise, and reliability!

Details: Doesn't turn on • Continuous feed (most common)

I recently had the pleasure to work with max from promax service group. He installed 3 new electrical outlets and did it with such an ease. He had to access our attic several times in order to fish the wire to proper location. He only did a neat installation but he also made sure to clean up any mess that occurred as part of the installation. I will hire max again for any future projects

Details: No, there is no existing wiring • Install switch or outlet • 2 switches or outlets • Rooms with water access, like the kitchen • Drywall • House

We found ProMax through Thumbtack to install a level 2 EV charger and additional outlets for our our bathrooms. I went back and forth with Nick on Thumbtack about job scope, availability, and materials required. He was incredibly patient, accommodating, and responsive with our questions and our schedules, suggesting to us that this would be a reliable contracting company. Max came out right away that same weekend to start the job. It was a half-day effort to due the small spaces in our bathroom, along with Max needed to run a ton of wiring from our panel in the back of the house, into the crawl space, and out to our garage where the charger was ultimately installed. He was incredibly clean and respectful of our house and the job we wanted. He brought all the equipment required (we’ve had many contractors come half prepared with tools; also, look at how organized his truck is), walked us through all the steps required for installation, and reconfirmed with us throughout the job that the outlets were installed exactly where we wanted. Moreover, the cleanup process afterwards was impeccable as he wiped down the floors where he worked inside our house and vacuumed the outside where there was drilling/cutting. Would highly recommend Max and his team, who are responsive, accommodating, and thorough in their work. We’ll be contacting Max when we are ready to do our HVAC/duct work in the attic.
