The installation process was super smooth, Eugene was very knowledgeable and explained the details and where the lines would be run. When the outdoor unit location was more difficult to install than expected, Eugene was happy to move the location and try to make it work. Everything was super smooth, Eugene was very punctual and detailed, the installation itself was very clean and precise, and his team left the place spotless and patched up areas so nicely. I am very impressed with his skills and attention to detail and would definitely use Fuse again for service in the future!

Years ago the apartment complex I lived at contracted Calvey to install mini-split A/C in the…read moreapartment I was in. The install was amazing quality! So much so that it gave me the confidence to buy my first home without A/C because I knew I could just call Calvey. A few years later I did just that. Damn, it's been a couple of months now and I've been able to control the climate of my entire house from my phone, optimizing the temperature and sometimes making it as low as 66F to just enjoy the air being crisp. The install has been fantastic quality and the crew listened to everything I wanted every step of the way. They mounted rat spikes where I wanted, they put the lines and the units exactly where I asked and I've had no issues at all. I truly believe with home price comparisons in my area that I made money off of the install because it increased my home value. My golden retriever is happy, I am 100% happy and I will see you guys again next home upgrade. :)

These guys may be ok, but I'll never know and I'll never call them again because they're very unprofessional. They misrepresent 'free estimates'... liars. Find someone else is my recommendation! Bad service, zero communication. FAIL.

He was very friendly on the phone and asked me key questions to help diagnose my issue. Since he was in the area, it only took him 10 mins to arrive. Once Sal arrived, he immediately confirmed the issue (blown capacitor), replaced it and the A/C was back in action. Sal was very friendly and professional the whole time and his price was very competitive! He also gave me helpful tips to prolong the life of my unit. Fantastic work by Sal! From opening up the Yelp project to CostLess fixing my A/C....less than 1 hour! Simply amazing! I strongly recommend CostLess for any of your HVAC needs!

I am more that happy with the results. This was a long term project. Ray was my contact and worked with me. They waited for 6 months as I was waiting for rebates to get approved from my utility. The approval came the beginning of July. The crew removed all of the old HVAC and installed the new system. This was just before the recent heat wave, so they worked hard to get it working before it hit. I now know that my old system was a POS. The new system has been excellent. It handled the 100F days without an issue.

The quoting process was straightforward -- no pressure, no mystery line items, and they actually explained the equipment options instead of just pushing the most expensive thing. Install crew was on time, respectful of the house, and left the place clean. Where they really stood out was everything after the install. Anyone who's done a permitted HVAC job knows the paperwork is where contractors go quiet. Not here. HERS testing forms, city inspection scheduling, warranty registration, and the maintenance plan were all sorted out. Hyman, Jean, and Khaled were each responsive whenever I needed something. No chasing, no dead ends. The system has been running well and the house is noticeably more comfortable. Easy recommendation.

Unfortunately, there was a communication mix up and some additional work was needed. With every other contractor I've worked with, this is where things get painful. You can't reach them. They push back. They argue. Not so with Fuse. First off, they have a call center so you can always reach someone, and that person is always helpful. Then, they really do work to make things right. We had an other technician out within a few days to make the small fix. Work was fast, and they showed up exactly when they said they would. They were also 100% unwilling to compromise on safety - and they were very clear on this. I want this in an electrical contractor. Anyway, I absolutely recommend Fuse and I'd have zero hesitation using any of their services again.
