He gave me all the information and answered all the questions I had, very nice! Communication was good thru the whole process. I opted for the foam to sprayed under instead of the timey batting you roll out. It actually is non toxic and lasts longer:)) Im already happy with it and can tell the difference already! Actually I had a couple places my floor creaked and now no noise there:)) Crew was super nice, on time and courteous. I am now in the process of getting a quote for the attic. I highly recommend this business!! Im a business woman and Im very critical of who I do business with. I give this company 10 stars!

When we bought our house many years ago I discovered a thin layer of blown in cellulose insulation…read morein the attic. It wasn't very even and being a bit of a handy man I added fiberglass batts over top. That made our house more comfortable. But since then we've had a couple of remodels, new roof, etc. In recent summers we noticed that the skylights in our house were much hotter than we remembered them being so one day I climbed up in the attic and saw that some areas had no insulation while others had far more than was needed. We decided we needed to have the insulation "fixed" - whatever was needed. A few weeks ago I called OJ Insulation in Morgan Hill. One of their estimators replied with a time to come by and we soon had an estimate. He agreed that we had plenty of insulation and it just needed to be "touched up"- which meant the guys would rearrange existing fiberglass to fill holes, put more strapping to hold batts thad shifted (like the skylight tunnels), etc. It wasn't practical to walk the entire attic to see exactly what was needed, so he gave me an estimate based on the living space - about $1/sq. ft. We got a time slot a few days later and on the morning a two man team showed up a few minutes early. They confirmed what I had asked to be done and they got to work. They took before and after photos which is helpful. They cleaned up and left the area spotless. It's been a couple of weeks since and we've had some hot days and I'm happy to report that there are NO hot spots in my house any more. Good job guys! Remember the estimate based on square footage? The estimator thought it would take the team 3-4 hours of work and I signed a contract of that amount of work. However, the guys were able to finish in about half that amount of time. I mentioned this to the estimator via email afterwards. He was surprised but gave me a discount on the price. I was pleased. On the basis of good work by their team and honest dealings by the management I am happy to recommend OJ Insulation.

Let me begin by saying that Ryan and his crew are extremely trustworthy and professional. I am an…read morearchitect and well-versed in air sealing, but I did not have personal experience with removing old fiberglass batt insulation and installing only two inches of closed-cell insulation. In our 1868 Victorian home, Ryan and his crew removed all of the old fiberglass insulation from remodels we'd done over the years and installed closed-cell insulation in the attic ceilings and floor. I'll admit that when I saw the large amounts of old insulation being removed, I seriously wondered if I had made the right decision. Rather than jumping to conclusions, I waited until I could compare our December 2024 PG&E gas bill with our December 2025 bill. Since we heat our home with a gas furnace, my focus was on gas usage rather than electricity. In December 2024, our house was cold--uncomfortably so. The furnace cycled on and off constantly throughout the day, and we experienced significant temperature swings. The old insulation simply could not hold heat. Fast forward to December 2025. While our gas usage in therms was similar, the outcome could not have been more different. Our home is now warm and comfortable. We keep the thermostat at about 72 degrees during the day, and at night we set it to 62--yet the temperature holds steady around 66 degrees all night. In other words, the heater doesn't even come on after we go to bed. The result is a dramatically more comfortable home with no increase in gas usage. I expected our December 2025 bill to be through the roof, but instead it remained essentially the same--with vastly better performance and comfort. I couldn't be happier with the results. I'm so glad I put my trust in Ryan. We finally have a warm home during the coldest month of the year, and going forward we will be using less therms per month.

What really stood out was their commitment after the initial service. They followed up to make sure everything was working as expected and that no new rodents had returned. It's clear they genuinely care about doing the job right, not just completing a one-time service. The crew was professional, punctual, and left everything clean. If you're looking for a company that stands behind its work and delivers lasting results, I highly recommend AttiCal!

The crew showed up on time and did a very thorough job.

They also showed us before-and-after photos, so we could see exactly what was done. We've definitely noticed a difference since the work was completed. The house feels quieter and more peaceful, and the temperature is much more even from room to room. We're really happy with how everything turned out and would definitely recommend Attic Bros!

Other HVAC reps I spoke with didn't want to help or even suggest rerouting ductwork to make it happen, but HVAC Gurus did. It was a complex situation working with the existing structure and a new addition. They did all new ductwork, a new furnace, and a cooling system, but the most challenging part was finding the right spot and successfully moving the return vent from its original location. That's when I knew I needed an expert, and that's why I chose them as my sub. As a general contractor, I value trades that can communicate clearly and coordinate with others on site, and this team did just that. Their pricing was competitive for the scope of work, and the quality matched the investment. Professional, reliable, and solution oriented, I'll definitely be working with them again and recommend them for any HVAC work.

The inspector said we needed an electrical permit as well and it took MANY phone calls and another month before HVAC Gurus actually pulled this permit. The first inspection failed because they did not install a GFI outlet on the outside of the house where some electrical equipment was installed. They charged me an additional $650 to resolve what should have been installed properly in the first place. The second inspection because they used flexible conduit from the electrical panel to the ceiling and code requires rigid pipe. They were also cited for using incorrect wiring colors, black wire for HOT line which has to be red to meet building code. This is pretty basic stuff. HVAC Gurus ignored all attempts to remedy the situation amicable and totally dropped the ball. I don't recommend this company to anyone. The workmanship is sub-par at best and they don't stand by their workmanship and their customer service is the worst! I also learned (the hard way) it's never wise to pay any contractor in full until permit inspection has passed. In the end, I hired a qualified electrician and it cost me another $600 to fix the wiring screwup. I would NEVER do business with this company again!

We had rodents dancing above our heads at night in our low head-room attic. We called Attic Pros…read morewho did a cursory "inspection" and recommended complete replacement of attic insulation, replacement of most A/C duct work in the crawl space below the house, sanitizing, and sealing up "all" entry points for critters. It was very expensive but we went with them mainly because the "inspector" (a salesman through and through) had excellent English and promised to personally manage the project. He answered one subsequent question and then disappeared, never to be heard from again. The estimated 3-day job took 3 weeks, with schedules shifting daily, different crews, minimal work days, redundant and often incorrect communication via text and email, and no explanations of what was going on. The crews were friendly but spoke minimal English. It was difficult to understand what was done, not yet done, or not intended to be done. Once they left, the critters remained. Staff came back 3 or 4 times to seal additional openings ... to the wrong area (crawl space rather than attic). The most recent visit by Jorge was very good. He had good English so his explanations were understandable and helpful. He found and fixed two more openings - these at roof level - and recommended a spray that can repel rodents from returning. I bought and used that (why don't they do that themselves?) and the first night at least was the first "quiet" night in months.
