    I had an outstanding experience with Plum HVAC. After my 66-year-old Carrier gas furnace finally retired, I decided to replace it with a Mitsubishi mini-split HVAC system. I consulted with four contractors and chose Plum because of their excellent reviews and competitive pricing--and I'm glad I did! From the owner Sam to the administrator Natalie and the installation crew (Jake, Alex, Andrew, and Ha), everyone was professional, responsive, and great to work with. Sam and Natalie went above and beyond to help me file my HEEHRA application just before the TechClean deadline for NorCal. Natalie proactively reminded me of the deadline, reviewed my application, and pointed out errors, showing their commitment to helping customers save money. Sam was straightforward, responsive, and open to my ideas--like installing the outdoor unit in the side yard instead of the backyard, which he got approved. The installation crew was meticulous, professional, and respectful, wearing N95 masks and protective suits when needed, and cleaning the work areas thoroughly after each day's work. Jake emphasized quality over speed, and I could see they took pride in their work. They even took care to hide electrical wiring behind the pipes, maintaining a clean and aesthetic look. Plum is a small company with low overhead, and they pass the savings on to their clients, making their pricing very competitive. I'm truly grateful to have found them--highly recommended!

    I hired Plum HVAC to install a Mitsubishi Multi-Zone Ductless Mini-Split system. The crew came before the scheduled time and even waited in the car for me to give them a green light to start the job because I had requested a specific start time. The crew was super efficient and got to work in different areas of the house. Each day after the job was done, they made sure all areas were fully cleaned up. The job was estimated to be completed in 3 days but the crew finished everything in 2.5 days. I was super impressed at their professionalism and how fast and clean they did the job. They were also priced pretty competitively. In addition, they also helped to apply for the Clean Tech rebate and got it back pretty quickly. Sam the owner is also super responsive with text. I'm very glad that I went with them and would definitely recommend!

    Newly installed Condenser for Heat Pump

    We hired Plum HVAC to install a new Heat Pump system for an attic of second floor through another site. Sam and team has done exceptional good job with quality and honesty so we highly recommend Plum HVAC to any customers on Yelp also who needs reliable and high quality HVAC work done! From Sam to his team, they place customer service at very high priority. You won't be disappointed!

    I highly recommend Plum HVAC! I reached out to six companies for heat pump HVAC quotes through switchison.org. Sam was the first to respond, and we scheduled a visit the very next day. I immediately felt a rapport with him, and he was super low-pressure. I noticed that he was not taking notes, photos, or measurements when he was surveying the house. He said that he just remembers everything! We discussed both ducted and ductless (6-zone mini-split) systems for our house and he quoted both. But it was pretty clear that the mini-split would be a better choice if we were ok with the aesthetics. Sam came on Friday, and he sent me the quote on Saturday - less than 24 hours later. I had the other companies quote only the mini-split. I don't regret getting the other quotes because I learned something from each of them. But they all came in at higher costs (some more than 2x!), and I still felt like Plum would do the best job. Despite his quote being the lowest, Sam quoted the higher-end "FS" models of the Mitsubishi indoor units, and the others quoted the "GS" models. Sam and Natalie helped me reserve HEEHRA, TECH Clean CA, and SVCE rebates and answered many other questions before the installation. Jake, Ha, Andrew, and Alex did the installation. They were a highly competent, efficient, and courteous team and they completed the job in three days. We are very happy with the performance of our system and with the whole experience with Sam and his team.

    Nest system working perfectly

    Sam and his crew really went above and beyond to make sure our HVAC system (dual heat pump/furnace) was perfect. Sam even drove out on his day off and made a special trip to Home Depot to get things just right. And now our system works perfectly! Would definitely recommend.

    I would give 6 stars if I could. I found Plum HVAC from Peninsula Clean Energy's list of approved contractors for HVAC. I replaced my central heating with a heat pump. Sam, the owner, gave me a quote that almost matched two other companies quotes (one being a family member's client so that must have been a close to rock bottom price) but Sam's quote included a better quality Bryant heat pump and a slim line condenser. The first company quoted with a Day and Night and the second company offered a Gree and both would charge additional for a slim line condenser. Sam was always easy to reach if I had questions for my HOA architectural approval, permits from Foster City (the building department is very...particular), or Peninsula Clean Energy loan and rebates. I couldn't be happier with the entire process with Plum, the work, or the interaction with installers Jake and Han who were professional, polite, and very clean. I am now enjoying my energy efficient heat pump and am ready for the heat! I highly, highly recommend Plum.

    I talked with several HVAC companies to replace my old system. After all the research and getting several quotes, I decided to work with Sam. He is very knowledgeable, professional and easy to work with. Their pricing was very fair compared to other quotes. They installed a dual system ( Heat pump + Furnace). It works perfectly!

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. :)

    I had an excellent experience with Henry from ThermaTech. My HVAC system stopped working properly…read moreafter another company had spent about two hours diagnosing it and quoted me more than $3,000 for a new control board, contactor, transformer, surge protector, and maintenance plan. Henry arrived, clearly explained each step of his diagnostic process, and quickly identified that the transformer and contactor were the actual issues. He completed the repair in about an hour and charged me $540 total, saving me roughly $2,500 compared with the previous quote. What impressed me most was Henry's honesty, expertise, and transparency. He did not try to upsell me or replace parts that were not needed. He took the time to explain what had failed, why the system was not powering on, and what he was doing to fix it. It is rare to find an HVAC company that combines strong technical knowledge with fair pricing and integrity. I would absolutely recommend ThermaTech to anyone looking for an honest and skilled HVAC professional.

We had no idea when it was last serviced or if it had ever been serviced at all. Henry gave us a very fair and competitive price for a tune up. Upon Henry's arrival, he was friendly and professional. He opened the furnace and showed us the burner. He explained it was in great condition considering the age of the unit and it didn't need servicing; although, he did clean up around a few areas around the burner. The blower motor was slightly wobbly, and once again, he explained it was still in good shape considering its age. He proceeded to the back patio where the condenser was located. He noted the unit was very old and that particular Freon is no longer available for servicing; however, he stated the unit did not need to be replaced just yet as long as it's blowing cold. Henry indicated despite our units being way past their anticipated life expectancy, they were clean and blowing hot & cold just fine. Therefore, no servicing was recommended and he did not charge us anything. We are impressed not only by Henry's friendliness and professionalism, but also by his transparency and integrity. Many other companies would have hopped on the opportunity to upsell the service or even sway us to replace our system right away, but Henry gave us peace of mind to give us time and to save up for an inevitable replacement in the future with Therma Tech. Thank you so much, Henry! We will definitely contact you again in the future and recommend you to all our family, friends and coworkers.
