Alex arrived on time and set about immediately to work. He worked for over an hour to diagnose why my furnace would not run when I set the thermostat to "on," and could find no parts that were not working and/or needed to be replaced. He also stated that he saw no reason why the furnace would need to be replaced now, as I had been told by another company. He observed an area that was rusted, though dry. He suggested that I schedule him to come back in a week to inspect that spot again. Alex was precise about his findings and explained things clearly. I'm confident that all was well managed.

After being bombarded after requesting information from Yelp, I chose fuse because they contacted me first and were able to explain same-day service and a very small feed to look at the problem with my furnace the repair man Alexander that’s the English version of his name was quick, polite, professional, and helpful. Explain the problem the price, and after agreeing, he immediately fixed it checked everything checked for gas leaks. Check the fire detectors as well without asking to ensure that everything was working and Sayf I highly recommend them.

Fuse is my go to for anything Electrical. They installed a sub-panel for a swim spa as well as Electrical for fireplace inserts. As usual, they always go above and beyond and are super helpful and professional. We know that electrical work done by Fuse is going to be done right and safe. They’re wonderful to work with.

Great experience with FUSE, again. This time it was a mini spilt. Alex and his team moved fast, tackled multiple points of work concurrently. There’s no “here’s my assistant who’s learning” going on here. They were done in 5 hours and it was a big install! I fully expected this would be done in two days but they are masters at their craft. I wish FUSE did full home remodels!
