Vincent and his crew were fantastic. I called Vincent last week during the heatwave. He came right away. A week later I have my AC replaced. He didn't leave until everything was working correctly. They are friendly and professional. They cleaned after they were done as well. Thank you!!!! I highly recommend. read more

Vincent was super quick and responsive, even was able to come by the same day to fix my heater. He diagnosed and solved the problem in an efficient manner, which truly showed how a professional and experienced person he is. I highly recommend Green Mechanics to get the job done when it comes to everything HVAC related! read more

Amazing work! Vince knows what he's doing and is very open to explaining his work, all for a fair rate. Green Mechanics troubleshot a furnace for me and also redid some related gas piping properly. Thanks Vince! read more

Vincent Dias performed my first annual maintenance on my new heat pump. I had many questions and uncertainties. Vincent spoke with me about the components of my heat pump in a way I now better understand how to use my heat pump to work efficiently. Vincent did maintenance efficiently and timely. He even finished work (a pipe) that had not actually been done well at time of going from heater to this heat pump. Vincent knows what he is doing! read more

I called Vince on a Wednesday because my parents' house do not have heat coming up in all the bedrooms. He was able to come take a look right away. He discovers so many issues. 1. Furnace was installed the wrong way which could cause fire hazard. 2. Furnace was hooked up the wrong way 3. Previous contractors did not bother to check our ducts, turns out it needs replacement. He reinstalled the furnace, cleaned up the attic and replaced the ducts for us. read more

Vincent is so great! He helped replace our 50 years old furnace to a new heat pump system, now it's running perfect and heats up the house so much faster! He also cleaned up all the nasty dusts and mice remains, washed and disinfected and sealed everything nice and beautiful! He even fixed my broken backyard door and some other small places altogether. I would definitely recommend him for anyone in need. read more

Vincent did an excellent job! He came into our home in the middle of a remodel. Our sub floors weren't even in at the time and my old system was completely removed for abatement purposes. Basically starting from scratch all my duct work, boots, vents everything were replaced. He even went as far as servicing my current ac unit and heating system to make sure we were being efficient with our usage. My new system is much more efficient then it ever was before. Especially the ac the house now gets several degrees cooler than it did before. That was huge for me. The heat doesn't run nearly as much that's a big plus as well. Thank you Vince for your attention to detail having dealt with several contractors and construction companies over the last few months dealing with Vincent was a breath of fresh air. read more

There are not enough words to say how great the service was that Vincent provided. 4pm I get home and it is 102º and it is 86º in the house and the AC is not working. I called and Vincent was here by 6pm and a look and was back with the part to fix the capacitor by 9:30am the following morning. Not to mention performed the maintenance and inspected everything else. He was nothing but professional, took pictures of areas of concern, and clearly explained what issues were and how he was going to fix it!! THANK YOU VINCENT! read more

We live near the SF Bay. Our home had a central heating system but no central air conditioning. With recent wildfires and air quality issues, we wanted to add central air conditioning. Vincent Dias, owner of Green Mechanics, removed the old heating unit and duct work and installed a new heating and air conditioning system including an air purifier and all new ducts last May 2021. We are very pleased with our new HVAC system. It has performed as expected based on Vincent's recommendations. Vincent will make the sales call, select the equipment, and install it. He is very knowledgeable and experienced in his craft. He communicates well and performs quality work. He gets the job done on time. My wife and I appreciated only having to deal with one person. Our experience with Vincent was very positive. read more

We had a very complex set of requirements for our home project. We wanted to reuse two furnaces, and create a total of five heating/cooling zones. Vincent got it all done on time and budget, piping the existing furnaces for A/C (didn't have it before), smart thermostats, additional furnaces, A/C units, and a full maintenance schedule with instructions. Great work, highly recommended! read more

Was having a Problem with AC condenser not shutting off, looked through a a bunch of reviews on Yelp as is my normal protocol came across GREEN MECHANICS who happened to be in Fremont where I live gave him a call and a text and he ended up responding very nice fellow by the name of Vincent Dias, generally at this time of year with the Heat Wave and all the people having problems with their HVACs I figured it was going to be a couple days yet Vince was able to squeeze me in for a look see, diagnose the problem, told me the parts I need to order, gave me a quote, ended up getting the parts which surprised me cuz of the supply chain issues these days and was done the next day! Problem solved, he ended up cleaning my unit and giving me some real good information on maintenance and answered all my questions super nice guy very knowledgeable very passionate about his work easy to work with, good communications. If I sound like I'm building him up I'm not this guy is the real deal, I've now added Green Mechanics to my go-to contacts and I'm sure I will be using them again in the future. read more

Vincent is wonderful!! Friendly, honest, responsive, knowledgeable. He installed a new central heating system in my house two years ago and I couldn't be happier. He is experienced in his craft and did the work well and on time. Two years later he is still responsive and available for questions and maintenance. I'm very pleased with Green Mechanics and would definitely recommend them! read more

This review is overdue. A few years ago Vince come out and install an AC. Not only were his prices reasonable - He was extremely professional, patient and thorough in making sure the unit was installed properly. About a year after the install, something malfunctioned in the unit and it wasn't cooling anymore. We called Vince and he came out the next day and fixed it for us. He dealt with the company regarding the warranty and everything. It was totally hassle free. Anyways, I recently moved and called Vince to see if we could have the AC removed to take with us. Again, he came out just the next day to uninstall it! We will continue to use and refer friends to Green Mechanics for all HVAC needs. read more

Hey for real this guy's awsome, personable professional on time. I had some a $$hole contractor sell me a used unit and the condenser was so loud my neighbors hated me, vince tore it out for free and only charged me labor on installing a new 3 ton fujitzu. Was there every morning tull every night until we were done, hese the man. read more

We are located in Livermore and of course we couldn't get anyone to come fix our AC in the middle of summer without waiting 2 weeks. Found Vince although he too was super busy he decided to come help us the next day even though he works out of Fremont. He was super nice and professional as well as knowledgeable. He gave us a reasonable fee and fixed our problem until we can get our unit replaced which we will definitely be calling him for. I'm 6 and half months pregnant and he knew how important it was to get things safe and working being a family man himself. He gave us advice on how to move forward with taking care of our AC issues. So glad I called him . read more

Wanted to give a shoutout to Vincent from Green Mechanics. He did a fantastic job installing a new HVAC unit in our house. We were in the process of remodeling our first house and had lots of questions. Not only did he answer all the questions but also educated us regarding various aspects of house maintenance. The quality of his work is very high. I whole heartedly recommend him for any HVAC needs. read more
