I had Eco Performance Builders install a ducted heat pump, attic sealing and insulation, and a heat…read morepump water heater at my house last year. I found the experience of working with them to be exceptionally positive. From start to finish, every member of the team I worked with was highly professional, knowledgeable, and responsive. I always felt like I was talking to a friendly expert, not a salesperson. They patiently answered all of my questions and worked with me to create a HVAC system that was perfectly tailored to my house. The installation work was smooth and efficient, and they were able to accommodate a few small change orders (e.g. relocation of a dryer vent) at a reasonable price. Their process for collecting rebates and incentives was very well-managed as well. Overall, I'm very pleased with my new heat pump and water heater. My house feels comfortable year round, and it feels great to live in a fully electrified home. I'd enthusiastically recommend Eco Perfomance Builders to anyone.

I could not be happier with the work that Eco Performance did to plan and install our new ducted…read moreFujitsu heat pump system. The entire team was thoughtful, thorough, and immediately communicative from start to finish. Eco Performance also helped me secure two grants from Alameda County that significantly lowered our out-of-pocket cost. Kyle, who did our initial estimate visit and helped me onboard with the team was a patiently thoughtful listener, and also very kindly put up with my myriad questions and odd sense of humor - much appreciated! Abby did a thorough analysis of our home's needs when she came out to perform the manual J calculation, and she designed what I'm sure will be a very cozy system this coming winter. Nick and the installation crew were competent, tidy, amazingly efficient, and respectful not only of our property but also our geriatric kitty (the real queen of the house). And Denise, the project's coordination mastermind was an absolute rock - answering any question that I had immediately and helping me successfully navigate the nit-picky grant process. The entire team has my strongest recommendation. I feel so lucky to have stumbled across this company, especially for a project of this scope. Thank you!

A very positive experience! We just has SDI insulate the exterior walls of our 1960's-era Belmont…read morehills home, and I was very impressed with the work they did. 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.

SDI came in quickly, priced the job well, and knocked it out fast. I was impressed by how fast they…read moreresponded to my request for a quote. I'll use them again for insulation and may even redo my fireplace!

I hired this company to do the work on my house that was recommended in a home energy assessment…read morecompleted last year. Initially Alex Minaboo, the owner, came to look the job over and in that visit recommended replacing all the heating ducts in the house. He tried to sell me a heat pump system which I did not want to do since the existing furnace is only three years old. There was nothing in the home energy assessment report indicating I needed to replace the furnace or the ducts. A few weeks later, the foreman (I think that is his role) came by to assess the job, and said he did not think the ducts needed to be replaced as they were still quite new. I opted to not replace the ducts but to proceed with the air sealing of the heating system that was recommended in the home energy assessment. Alex later said the air sealing could cause a problem for the furnace, which he said was too large for this size house. He suggested that adding an additional heat register might mitigate a potential problem with rapid cycling, and I opted to do this. In the course of All Things Good sealing the heating ducts and adding the new register, the blower on the furnace stopped working. Alex deflected and denied responsibility for his company causing the problem, disparaged another company that had installed the furnace, and argued that his company could not be held responsible for damages when something breaks in an old house while they are working on it, referring me to a clause in their contract. To fix the furnace, All Things Good charged $1200.00 in labor costs (for a job that took no more than 2 hours on site) and the blower was about $700 more). I have always thought "if you break it, you fix it" and I was floored by how this was being handled, but since I do not know HVAC systems and could not in good conscience argue that I was certain the breakdown was caused by their work, I proposed we split the bill for fixing the furnace. My offer was refused. Alex then had the gall to argue he was already giving me a discount on labor costs, and threatened that if I did not pay he would put a lien on my house. I paid the bill because it was not worth my time to fight with All Things Good. I see a number of positive reviews here and at least one that is like mine. My experience was very unsatisfactory and I will certainly never use this company again.

The team was professional and fast and they went above and beyond in explaining the water heater and the app. They even installed a new light in my basement so they could complete the work, which is helpful to me as well. And then they came back and installed some additional insulation to mute the water heater noise. The office staff was also excellent and very responsive and helped me get all the rebates I was eligible for. Look no further, All Things Good is the team you need .
