Their communication with me was excellent, and everyone I interacted with was extremely professional and very skilled in their respective tasks. Big thanks (!) to Joran, Sergio, Gene, David, and the other crew members whose names I didn't get. TY! I feel very comfortable recommending SDI's work - they did what they said they would do, and they did it quickly and professionally! Their estimate was competitively priced; it was neither the cheapest nor the priciest., but all things considered, SDI seemed to offer the best value for our money. I'm also very pleased with the results of the insulation! We had R15 fiberglass blown into our exterior walls, and even after just one night I can tell the house is much quieter. Today's outside temp has been in the mid-50's, which is chilly for early May, so I'm able to write this review with oddly good timing: new insulation works, lol! I'm now very eager to see what it does in the summer heat, which was our main reason for having it blown in. All in all, I am very pleased with the SDI did on our home and feel quite comfortable recommending their services to other homeowners.

He also showed me how to work the thermostats correctly to switch over to the backup old gas furnace if needed. Thanks guys!

They planned the system out well and came to adjust things accordingly in the months post install to ensure it was running perfectly. Recently, prior to selling my father in law's house in Oakland, they installed a vapor barrier that was suggested by an inspector. We needed it done in a timely manner due to the sale timeline and they were responsive, professional and reasonably priced plus they did a fabulous job. Thank you for your service!

After meeting in person with numerous HVAC companies, my wife and I decided to move forward with…read moreCalvey Heating and Air. Michael Calvey thoroughly explained all of the options for our house's specific HVAC needs and was very patient with me as I asked a variety of questions. In fact, he made numerous trips to our house to answer the constant flow of questions my wife and I had. Bottom line, we built a solid working relationship with Michael and this gave us the comfort we needed to move forward with our HVAC investment. Calvey Heating and Air's estimate for a new heat pump and furnace at our house was very competitive. I was amazed at how much the pricing varied from vendor to vendor. Michael and the Calvey team made the entire process seamless from start to finish. Michael recommended an electrician who did a great job with our electric panel upgrade and the permit team did a fantastic job working with the city for all of the required paperwork. When it came time for the installation, the lead installer, Servando, and his team took pride in their work for the two day install. Similar to Michael, they were patient with me and answered all my questions during the install. Following the install, the Home Energy Rating System (HERS) Team promptly arrived and conducted the necessary testing. Lastly, the permit team met with the city building inspector to successfully get the city sign off on all of the work. Throughout the entire process, Calvey Heating and Air did a great job choreographing and managing all aspects of the installation. I was constantly kept informed and Michael and his team visited our house daily during the installation to ensure all was moving forward properly. Lastly, a final walk-through was conducted by Johnny from Calvey ensuring that the install was 100% perfect. Once my wife and I have had time to work with and get familiar with our new system, Michael indicated he will have his team come by our house and balance out our vents if needed and answer any additional questions we may have. Overall, my wife and I cannot be happier with our decision to have Calvey Heating and Air install our new system. Their service was great from start to finish and there were no hiccups. We highly recommend them. Thank you Michael Calvey!

Michael came out to my house and walked me through the pros and cons of a heat pump HVAC. For my home, the extra money made no sense. I really do not need central AC. We then talked about a new Carrier, high-efficency furnace. That was exactly what I needed. I also opted for the Ecobee Smart, wi-fi enabled thermostat. I am extremely happy with everything. The price was right. The installation was flawless. The post-intall QA walkghrough, by Johnny, went really well. ThenI worked with the folks that checked all the boxes post-intalleation. HERS test was easy with a pass.. Today, we passed the inspection, in under 5 minute. Every person I dealt with was amiable and professiona. The office staff always very nice. Michael Calvey was a joy to talk to. Thank you to Johnny, the project manager, and the folks from HOPSTER that facilitated the post-installation test and inspectioin. From start to finish I met with Michael on February 12th. The 16th the new furnace was intalled. February 17th Johnny did the QA walkthrough. February 18th HOPSTER did their pre-test and inspection walkthrough. The HERS test was done February 23rd. March 5th the city inspection was complete. I will continue to use Calvey for annual maintenance

I met with three HVAC contractors and Noam was the only HVAC contractor who honestly told me that I didn't need a new furnace, but I needed to remove the asbestos in my attic and get new attic insulation. The other HVAC contractors were not qualified to help me with my attic insulation and one contractor said I had no asbestos, but Noam , who is certified for asbestos removal, said I did have asbestos. I have peace of mind knowing that Noam was honest with me in telling me what I truly needed. His crew also did an excellent job installing my garage roof insulation with a ceiling fan. My garage gets incredibly hot in the summer. I look forward to having a cooler garage and house during the hot summers and a warmer house during the winters. I highly recommend All Bay Insulation & HVAC. My doorbell was not working and when Alonzo from All Bay Insulation & HVAC went into the attic, he discovered that the wire to the doorbell was cut and the wire next to the doorbell ringer was also cut. Since we don't know who cut the wire, Noam offered to have Alonzo install a new wire for free. Alonzo had to break through my kitchen wall to install the wire and when he repatched the wall, the wall looked good as new. You cannot tell that the wall was re-opened to install a wire. My doorbell now works perfectly, and thanks to Noam, I didn't have to pay a cent for this repair.

After some searching, I reached out to All Bay Insulation & HVAC, and I'm so glad I did. I called Noam (the owner) on a Wednesday, and he and his crew Cande came out promptly--actually arriving early and ready to get started. From the moment they arrived, they were professional, knowledgeable, and incredibly patient in answering all my questions. They took great care of my home--wearing shoe covers, taping down the kitchen area, and keeping everything clean and tidy throughout the process. They thoroughly cleaned all the ducts and bathroom vents, and even went above and beyond by cleaning the dryer vent at no extra charge. What really stood out to me was Noam's honesty. He pointed out that a section of my air duct had been squished by someone who had previously been in my attic, and instead of upselling me, he told me it was an easy fix I could handle myself for about $10. It's rare to find someone this trustworthy, detail-oriented, and respectful. I highly recommend Noam and his team--great service, great people, and a genuinely positive experience from start to finish.

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.
