    Sealing air leaks

    Ruben was a pleasure to work with at Greenstar Attic. We contacted several companies to evaluate our attic insulation and during the consultation with Greenstar, Ruben was knowledgeable, honest, communicated well and quickly through messages and over the phone, and provided numerous options to fit our budget. Since our original insulation was in good shape, we decided, based on Ruben's recommendation, to add more blown-in insulation to our existing insulation and use Greenstar as our contractor. During the day of installation, Ruben provided us a heads up and showed up promptly at the time we scheduled. Ruben and his team took their time to prep our home, ensuring that any space they needed to work in was fully covered with protective plastic. Ruben was thorough in completing the job, taking photos of the process and communicating with us through the time he and his team were working in our home. Ruben took time to show me the job he had done in the attic, and then his team carefully cleaned up after the project was completed. Ruben finally shared all of the pictures he took of the project that included sealing air leaks around fixtures, installing soffit baffles, a temperature controlled gable fan, and of course the new insulation. We definitely have noticed a difference in the comfort level of our home during this last week of high 90s that the new insulation has made. We totally recommend Ruben at Greenstar Attic Insulation if you are looking at reinsulating you home.

    This company did an excellent job upgrading the attic insulation in my house. Reuben is very knowledgeable and hard working. He uses excellent materials and equipment. The cost of the project to me was very reasonable and I am completely satisfied with the experience. I strongly recommend him and I am grateful he fixed my situation. Thank you very much Greenstar Attic insulation for

    I have been waiting 4 months to write this review to see if I would have another HVAC issue and so…read morefar it's been smooth. I have been really skeptical of all HVAC companies in the past 5 years. I have been burned by so many HVAC techs and wasted so much money. 4 different companies went through with different shadiness levels giving me different answers for the same HVAC issue. Every company kept telling me my freon was low and i most likely had a leak. One company even told me to just replace my brand new system cause "it was from China" The Jaguar tech (Jeff) definitely gave me some disappointed head shakes at previous work but was the only one to truly put his head down, work, and diagnose the root cause of the issue. He checked every part of the system before he gave me an answer on what he believed was wrong. After the diagnosis he detailed every part of the HVAC unit (and attic unit) and explained to me what he was looking for, what he found, and what he believed was the answer. I never felt like he was up-selling me. It wasn't even a freon issue to begin with and the filter drier needed to be replaced. After another visit and a 4 hour procedure my HVAC unit has been running smoothly all Summer 2026. I will seriously only call this company from now on.

Since I wasn't at the property, I had asked for a quick update. The work was done so fast that the invoice popped up on my phone almost immediately! The only reason I'm giving 4 stars instead of 5 is that I didn't receive a call with an estimate or breakdown of what was needed before the work was performed. Overall, though, it was a very quick and seamless process.

A couple of years ago I noticed the amount of energy we were supposed to be getting with our solar panels had severely decreased as our SMUD bill increased. Someone recommended getting the panels cleaned. I saw a sign for Sierra Maintenance leaving our neighborhood and decided to give them a call. After they cleaned the panels, I noticed a lower SMUD bill the next month and in the subsequent months and even to this day. They also send before and after pictures which show just how filthy the panels can get. They also cleaned our gutters this time which I didn't realize had a ton of gunk in them. Our home is two-story ~ 4k sq foot. We have about 12 panels and it was ~$200 to clean them plus another $360 to clean the gutters. Excellent company, which I will refer to others as well as use again next year.

I've gone through a lot of companies before finding them, and none came close in terms of consistency, professionalism, and actual results. Our home isn't easy. We have massive glass panels, some reaching 22 feet tall and 30 feet wide. It takes precision, the right equipment, and a team that actually knows what they're doing. These guys handle it without hesitation and the finish is always spotless. They take care of everything for us. Windows, gutters, solar panels, driveway, concrete, and more. I also use them at my Serrano property and on my flips, and they show up the same way every time. No shortcuts, no excuses, just solid work. If you're tired of hiring people who overpromise and underdeliver, call Will and his team. They're the real deal.

    The guy Mark promises a free tech visit for inspection. "Fixes" your problem without discussing or…read moredisclosing any details, then harasses you to pay an exorbitant price. The problem is never fixed and they want more money but will discount the money that they already forced out of you. Dishonesty and misdirection is their main service. My home is still under builder warranty and I just needed someone for second opinion. Mark promised me free inspection. I specifically told him not to fix anything but just give me a quote and problem list with my gas fireplace. Sends a technician that has no certification or skills, talks over the phone walking the technician in Arabic. The technician tells me he fixed it, charges me $480, later to realize that the actual charge is $250. Fun part, he will only accept direct transfer via Venmo only for payment! Next time we use the fireplace, same problem. Mark tells me, upon contacting him, that there is another possible problem. But since I am a returning customer, instead of charging me $1200 to fix it, he will charge me only $780, and discount me another $250 that I already paid. Stay away from this company. Edit(03/06/2026) Your comment shows pure shrewdness and proves my suspicion of false promises and lack of professionalism and integrity. I have posted a picture of my conversation with you on yelp. And it's not 19 months old but a month old conversation for the work your incompetent technician did on November 2, 2025. Damaging my fireplace and stating that my review is false is very concerning and misleading. I hope no one else faces this. Let me know if you need more pictures of the work your company did and the damage bill from the builder.

    Super nice, fast service, very friendly and explained recommended service for maintenance.read more

    A++ Company! So,…read morefunny story about how we connected with this company. We stopped by my in-laws' house in EG last night. It had been a hot day and we noticed the A/C fan in their house was blowing loudly but it was sweltering inside. Took a peek at their thermostat, which read 77 but felt more like a 87 in our house. Temp was set for 72, but was not cooling. We commented that their A/C didn't seem to be working. Father-in-law said he would call one of the companies that sent an ad in the mail for "$49 A/C Tune-Up." We told him it'd definitely cost more than $49 to fix the issue, and that was just a ploy to get customers to call them and upcharge. I told them we'd contact the company that has helped my parents in the past. So I quickly logged on to Yelp to find the company. They were pretty quick to respond in the past, so I figured they would call the next day and set up an appt. I sent a message to them and was very surprised when I got a message back from them in minutes! Gave them a call and Vince told me he actually had a guy finishing up a project in our area. I was shocked because it was almost 8pm! He said they had two shifts for their company, since people are having A/C issues around the clock. Long story short, Brian showed up around 10-15 minutes after I got off the phone with Vince. I was kinda in disbelief about how fast everything had happened. We definitely didn't think we'd find a company who could make it out to their house while we were still there! Brian diagnosed the problem as the unit lacking refrigerant. Added 2 lbs of R22 and pretty soon we could feel cool air circulating through the house. Throughout the night, Vince kept in constant communication with us and had a fantastic sense of humor. When I told him the A/C was working now, he sent a Carlton dance gif, lol. After Brian left, Vince sent me an invoice. When I saw it, I thought, "Oh interesting, they changed their logo." A few minutes later, I realized I had actually messaged a different company on Yelp than I had intended. The companies' names are practically identical, except the other one had the word "plumbing" in it, lol. I told Vince of the mistake and we kinda laughed about it. He said, "We were meant to be!!!!" :) I was able to pay via Venmo and Vince was able to give my in-laws a senior discount. It was not cheap, but based on how quickly they were able to fix the issue, the convenience was worth it. Highly recommend this company and they will be our go-to in the future for HVAC repairs. Thanks, Vince and Brian!!
