I had Restart HVAC come in for a maintenance visit covering both A/C and furnace, and the overall experience was outstanding. Communication with Ardana was smooth and seamless. The technician, Georgy, was excellent -- knowledgeable and patient. During the visit, he walked me through the different components of the AC and furnace, explaining what each part does and how it works. I also appreciated his honest assessment, free of unnecessary upsells. read more

We had Restart do a complete replacement of our HVAC system to a Mitsubishi heat pump while renovating our house. They removed the old furnace, AC compressor, all ducts, and installed the heat pump in a new location, as well as the air handler in the attic and all new vents and ducts. Alex was the main installer and he was absolutely fantastic - very helpful, patient, answered all my questions, and went above and beyond to make sure everything was done how we wanted. The system is working great and I love how quiet the Mitsubishi heat pump is. I would recommend Restart. read more

My tech, Georgy, came prepared! He had the part I needed, and I was up and running in 30 minutes. Like a cool breeze on a hot summer day. Way to go, Restart HVAC. read more

They were very quick to respond. I appreciate that they didn't try to oversell what was wrong with our AC and try to talk us into an expensive replacement. The first company we talked to 3 months ago try to say the unit was completely gone and needed 20k+ to replace just the unit no furnace or duct work. Restart HVAC actually rediagnose the problem and even though the unit is old they went over options for the unit. If we are to eventually replace the unit definitely contacting them first. read more

I have worked with many different HVAC companies and this was the best service I ever received! Georgi is highly skilled, extremely open to figuring out the solution. Since I am a tenant, I didn't know how to access my heater furnace. Turns out my unit was on the roof and Georgi spent a lot of time in finding the access route. He then did tune ups and maintainence for our system. Georgi even educated us on how to maintain our HVAC for efficiency and preventing issues. Highly recommend Restart HVAC for your needs! read more

Lots of HVAC repair people won't touch gas wall heaters, just try to sell you something new. Not Restart. They're great. Georgy, the HVAC tech, is a real pro. Polite, showed up on time, and got the job done quickly and for a good price. I had a tiny gas leak in my Cozy wall furnace. Georgy showed me where the leak was and then fixed it fast. Used little booties over his boots. Left the place clean. Highly recommended. read more

Restart HVAC did an incredible job cleaning and doing some maintenance on a two zone mini split at one of our properties. The coils were baked in dust and cat hair, and when these guys finished, everything looked brand new! They showed up on time, were very professional, and resolved the issue while being the most reasonably priced out of 5-6 other companies I contacted. I'll definitely be calling them in the future! read more

I've used Restart HVAC for a yearly HVAC maintenance. They responded fast, checked everything and didn't try to upsell for extra services. Technician was on time. Communicated well and explained all the details about the what need to be done now and what next year for the AC maintenance read more

Restart air was awesome to work with. Highly recommend this company. We had an issue with our mini split system and contacted multiple companies. Most companies would not even try to diagnose what the issue was or work on the system. Or they would try to upsell us on central air. Restart air Came out the next day, diagnosed and refilled my refrigerant to get the heap pump back up and running. They were very honest and transparent during the whole process. I will be retuning to Restart air for any future needs. Very happy to find a great company in the Bay area! read more

Awesome appliance repair service! A small wine fridge suddenly went out after we were out of town for a few days. Restart HVAC responded promptly after we messaged them on Yelp and showed up exactly on-time at the beginning of their visit window. George spent about 45 minutes diagnosing the issue and discovered it was an electrical issue (not an issue with the fridge itself). He saved us over $600 on an unnecessary new fridge and charged a very fair $60 for the visit. Would absolutely recommend Restart HVAC to take a look at any appliance issue before purchasing a new one! read more

Update to last review: Initially, there was an issue with miscommunication & an operator/dispatch irresponsibly accepting the job & failing to tell the HVAC team my needs. As I sat shivering with a broken heater I unleashed. Well, the company did attempt to make good from their end. It very much seems that they fired the operator that had misled me. They also said he was rude to me, so had to go. I appreciated that. The HVAC team dispatched also went & purchased a new extra long ladder to attempt to make up & finish the job. I had completely forgotten about my shivering scathing review until the company reached out to me recently to apologize for what happened. So I feel that with their attempts to make good & the obvious concern for their good standing with customers, they deserve an update in the other direction. read more

I have a very old AC. It stopped working in the middle of summer heat right now. George came over right away and quickly identified the issues. I am quite impressed with his troubleshooting logic. Also identified the potential thermostat control unreliable issue. This is exactly matching my past experience, which I did not tell him up front. Now the unit is back to normal, which I was worried that I might have to replace it. Highly recommend the service. read more

Good response time. Excellent service, quality and good value. Alex did a good job replacing the furnace.

This is not the exact photo of the man that helped me but it's similar of the AC that he worked on.

Thanks again for your honest opinion and work. read more

Very quick to respond. I sent the request at 10 PM, got the reply in a few minutes, and booked the appointment for the next day around 12-2 PM. They contacted me in advance that their technician could come 30 mins earlier. Great for me as I am waiting for the furnace fixed to heat the house again. The technician quickly found the issue and provided several good advice. In my case, my wall socket behind the furnace malfunctioned. It was very hard to reach/fix. He helped to find a temperature solution quickly. In the end, he charged me the diagnosis fee, which was very competitive compared to a few other quotes I got. Overall, 100%. Will definitely come to them if I face HVAC issues in the future. read more

Our heat went out last night and it was very quickly unbearably cold in the house. I went into Yelp and requested service callbacks. With a minute Grace from Restart HVAC has texted. She gave me the price for the service call which would be taken off of any repair and had a technician available to come out today. Georgy, quickly diagnosed the issue, a faulty gas valve. He had one on his truck and had it replaced and the heat on within a half an hour. Fantastic service; would definitely recommend! read more

What can I say about Restart HVAC? Let start off with the customer service, from phone call to the project being finished they were always informing us and making sure that we were kept in the loop at all times. Which is very important because this year has been a big one for us when it comes to renovation and adding a new HVAC system for our home. We needed to install a 3 ton unit because the airflow of the house was not reaching the far end of the house so they were able to add ventilation system throughout. To make sure it reached to the backside of the house, our home is about 3800+ sq ft so you know we needed two units. Beyond blessed to have found Restart HVAC, will be using them and recommending them in the future. read more

We had a problem with our dishwasher and sink grinder and not only was Restart HVAC very responsive, but they also sent Georgy who did a great job fixing it all. He is a humble, very pleasant guy and it was a pleasure meeting him. We for sure know who to call next! read more

Restart HVAC has one of the cheaper initial diagnostic fees, so we had them come by to look at a problem where one of the zones in our AC system was not working. Georgy figured out the problem with one of the dampers in our duct right then and there, also was he was helpful answering a few questions I had about our hvac system. read more

My family up in SF needed a full HVAC replacement because it just gave out at the beginning of the month, I'm happy the weather has been warm/cool enough to withstand but now we gotta prepare for the summer heat that's about to come up. Called up a few companies for them and they met with many, but ultimately went with Restart HVAC, they are amazing from start to finish getting this properly taken cared of. The most important part of the service to me is the level of service and if it matches what we paid for, getting a bunch of quotes before hand they were definitely in the right price. They finished a week ago, and this is why I'm writing the review because it's working better than it ever has. Grateful for the crew that worked on it with us! read more

Georgy did a great job, identified the issue quickly and fixed everything under two hours. Will definitely choose their service in future.
