Valentin is the best! I’m so grateful for the amazing expertise and help he provided me about the new unit in my home. He took time to show me tips I can do myself to make the AC run more efficiently. Great service and effort!

Have a very old wall heater that is temperamental. Scheduling was super easy, the service was on time, very affordable and professional. He was super nice and got the job done very fast. Would use again and highly recommend!

I have been regular customer of FUSE and just have done with gas pipe exchange. Job was done nicely and professionally by Valentin. Very happy with communication and service.

This is the second apartment I’ve had Fuse install heat pumps in. Both experiences were great. Team was on time, cleaned up well, kept the work contained, and the systems operate perfectly. They even conquered some tricky electrical issues with a crowded panel, all up to code. Would highly recommend!

A super professional and efficient team from Fuse installed our apartment heat pump units and motor. The install required complex electrical routing that came off without a hitch. We are very happy with the install and highly recommend Fuse to anyone looking for their services.

Update: they finally came out and corrected the piping and we passed Inspection. It did take Six months for this to be corrected so I subtracted a star. As of right now, everything works. We had a very disappointing experience with Fuse. They installed our HVAC system, and it failed inspection due to improperly installed condenser piping. The inspector specifically noted that the pipes were installed using a shortcut and need to be properly decoupled. What’s most frustrating is that this is not a gray area — it’s a clear code/compliance issue. Despite this, Fuse is now refusing to correct their own installation without charging us additional fees. Before the project, we were explicitly assured by Lexi at Fuse that the system would pass inspection and that if anything came up, they would take care of it. We relied on that guarantee and paid in full. Now that there’s an issue, they are going back on their word and trying to charge more to fix something that should have been done correctly the first time. This feels like a bait-and-switch. We paid for a complete, code-compliant installation — not something that fails inspection and requires additional money to fix. I would strongly caution anyone considering Fuse to get everything in writing and be very careful about relying on verbal guarantees. Based on our experience, once they are paid, accountability becomes an issue.

We have used Fuse multiple times now, mostly for installing new electrical outlets in bedrooms and bathrooms. They always do a great job of communicating, and patching up the holes that were made. I've had electricians in the past that had cut out such bad Frankenstein holes that it ended up being more work for me to patch up afterwards. Their work has always been high quality and I appreciate the extra steps they take in making sure my house is left clean. We will continue to use Fuse again in the future!

FUSE service was outstanding! We’ve tried other HVAC services and had frustrating experiences, but FUSE was efficient, fast, got the job done and the price was very reasonable. We’ll use them for all our HVAC needs from now on.
