Estimator showed up on time and answered our questions. He wore shoe covers to keep our floor clean. They were able to send us a quote by the end of the day which included the things we wanted to get done. The furnace replacement was scheduled fast and installation took about a day to complete. They covered the path from the front door to the furnace while they worked. They kept the work area clean. They wired up the furnace to our existing 3rd generation Nest thermostat. They included a new furnace filter. The furnace is working great so far. Accepting the quote and payment was easy online.

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.

The central Air Conditioner condenser (a large box with a fan outside the house) has died in the middle of the heatwave week in August. I found Fuse HVAC & Appliance Repair on Yelp and called them for an appointment. Long story short, the next day, my cooling system was up and running again, and what is most important, I didn't pay a fortune for that. Technician's name was Sergey L. I much appreciate his professionalism and human touch. The guy has not only quickly fixed my system but without any hesitation, was ready to go the extra mile for me and made the test of each system components, including heater/furnace on the attic, drainage system, thermostats, floor-by-floor zoning. What can I say after that? I guess I finally found my HVAC service company and will be happy to recommend them to my friends. Thank you, Fuse!

Excellent company! I had some problems with my refrigerator. The inside temperature was getting higher and higher. I noticed it in the evening of July 3. The next morning, on July 4 (when many companies were closed) this company found the way to send a technician within just several hours. Detailed diagnostic was done, the cause of problems revealed, and the next day they already had the replacement part. The same technician came (despite his very busy schedule on that day), and made the repairs. Very big "Thank You" to this company; they treat the customers like their close friends or family members. Highest level of responsiveness and responsibility!

The technician was very prompt,courteous and knowledgeable. He was very patient; I had an appointment I had to go to and he waited for me to return without any problem. I will gladly use this company again.

They showed up to on time,got my heating fixed. However, my online invoice did not have a breakdown of the work performed, which required me to call. I was provided with a new invoice, however it still wasn't very clear.

BUYER BEWARE. DO NOT USE THIS COMPANY IN NASHVILLE. This was an unfettered disaster. Technician misdiagnosed the issue, spent all day trying to fix while I stayed home from work, then told me it would be 2-3 business days to order more parts for my non-functioning fridge. I had to hire another company to complete the job. Also, major communication issues as we had a significant language barrier. Avoid at all costs and hire the factory authorized service company even if it takes an extra day to get on their calendar. Extremely unsatisfactory outcome for a Home Advisor recommended vendor.
