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!

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.

I am very impressed with his skills and attention to detail and would definitely use Fuse again for service in the future!

I was having a difficult time finding someone to simply replace the filter. The AC is working great, so it's a simple project. Other companies claimed I'd need to do "all suggested work," which sounds like a potentially expensive agreement. Gary was my technician. He was on time and very helpful. He even ran to the hardware store to buy the replacement filter, after checking the current product #. Freon offers an easy payment link and the ability to see the approx arrival time for your tech.

I had shopped around and found them to be very competitive and they had a solid reputation. The unit has been working flawlessly ever since the installation but though it was time for a maintenance/checkup. I called for an appointment and was quoted $95 for a checkup... I thought that was reasonable considering it had been over 5 years since the installation. The owner, Barsin stopped by and did a thorough inspection, checked the refrigerant, condenser, inspected the main unit, filter etc. all was well which I suspected but just wanted to be sure. He even popped his head into the attic to look at some of the duct work which is the original to the house but still functioning. When he completed the inspection I asked him how he would prefer to be paid and he said "No Charge", everything is working as it should so you are go to go... I thought that was pretty swell:). Anyway, just thought I would pass along a very good HVAC service/ company in the South bay for those looking for a competitive price, quality products and great service... Even after sale service!

Both Nahira and Rolando handled the removal of the old unit and the installation of the new one smoothly. After the job was done, they clearly explained how to use and maintain the new system.

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.

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. :)

John was amazing when he came over to my house. I had previously interviewed and hired two other contractors to come in to look at my AC unit and they did not know what the hell they were doing. By the time, I finally reached John, he knew exactly what was wrong! He is super honest and his price was amazing depending on what your issue is with your AC. My issue was I needed a new compressor which the other two bozo clowns couldn't figure out. My only regret is that I wish I found John as my first contractor instead of interviewing and working with the other two bozos! I live in Newark.

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.
