A-1 answered every question confidently, corrected a spec error in their own quote when I caught it, and put everything in writing before I signed. Install day: Austin, Joey, and Edgar showed up on time. Floors covered, shoes covered, house treated well. Two days -- day one removal and new equipment, day two ductwork and zoning. Heating and cooling tested before they left. Full documentation handed over on the spot. No hidden charges, no surprises, no change orders. Price was mid-range among four quotes, but the warranty structure -- lifetime workmanship, no-lemon guarantee, payment at completion -- made it the best overall package. Still have HERS test-out and city inspection scheduled, but based on every step of this process I'd recommend A-1 without hesitation. Austin, Joey, and Edgar did a great job.

He was professional, honest, and very easy to talk to. We felt comfortable right away. Couple days later, his team came out and completed the insulation in our home. They did a great and very precise job. You can tell they really care about their work and pay attention to the details What I appreciated the most is how clean they left everything. They used rugs to protect our floors and made sure to clean up after themselves. When they left, the house looked just as clean as before they started. Highly recommend Carlos and his team if you're looking for quality work and great service!

On the day of my appointment, I received a text from their field technician, Samim, letting me know he was on his way and would arrive in 20 minutes -- and he did, right on time. He was polite, introduced himself professionally, and was wearing protective gear and shoe guards to keep our floors clean. He went up to inspect our attic and explained that, given how our roof ridges are constructed, a radiant barrier installation wouldn't provide much benefit. He showed me photos and walked me through the reasoning clearly. It's rare to find a company that's upfront and honest instead of trying to upsell you on something you don't need. Really appreciated the professionalism and integrity -- highly recommend!

Wesley suggest someone named Neo that works with him. I texted Neo and we selected a date and Neo choose 9AM as my schedule was open for the day. On the day of the appointment; 9AM came and went. I texted Neo to ask if I had the date wrong and did not receive a response for over 30 minutes. When he did respond; he stated that he would be at my home if 15 minutes. I texted back that I was not at home. As I was pulling into my driveway, I saw a truck loaded with work materials pull up and stop across my driveway. I got out of the car and came into the house. Once inside, I did a quick task and went back to the front door to close and lock all the doors. As I Iooked outside, I saw the same truck parked across the street. The guy got out of the truck, walked up my stairs and rung my door bell. I do not know if he was drunk or high but there he was. His excuse was that he has something happen with his child. He insisted on coming in and taking a look. I declined. He insisted several times. I told him to get off my property and that I would be calling the office to let them know what had happened. I did call their office and let the receptionist know what had happened. She apologized. I tried to call Wesley to talk to him and left a voicemail. I never received any response. As a Black Women that has lived in Oakland for a long time...... I would not recommend this business to anyone especially women. As a good client, you should be heard and respected always!

Rats got into the crawlspace under our house via gaps in the side vents. When my home trapping…read moreefforts were unsuccessful in capturing much of what had become a large infestation, I contacted four companies to inspect and provide quotes. One company provided a $17K quote excluding replacing the attic insulation and refused to do the project unless I paid for a concrete rat slab install. This was our first issue of this type after 20 years in the house and I did not see a need for a concrete rat slab. The other three companies were more price competitive. I thought Sean provided the best inspection presentation and discussion, explaining considerations, answering my questions and working on a plan for long-term resolution of the problem while managing to a reasonable cost. I selected Mr. Attic for the job and Sean and Rachel proved to be good communicators and project managers. We had them clean out and rodent proof our attic as well, even though there was no recent sign of rat activity there. There was significant damage to HVAC ducts under the house which Mr. Attic cleaned, repaired, and replaced as was needed, and we also had them replace the insulation in the attic. Our total project cost was one-third of the "slab required" company even with attic insulation added. The crew that did the work was professional in their actions while working throughout our house and did a great job clearing out all the old materials in the crawlspace and attic. They rodent proofed the attic, crawlspace, and even our garage to close off any points of entry. We believe their HVAC duct work and attic insulation has benefited our household climate control and reduced energy usage. We just hit the two year mark since the last rats were captured and there has not been a single reoccurrence. I was very pleased with the work done by Mr. Attic and have recommended their service many times to others experiencing rodent infestations.

I would say, they did an excellent job - Starting with Jeremy, who accommodated my schedule for preliminary inspect and gave me a on the spot quote. Elder and the guys did an excellent job in covering up the entire house and finished the job in 2 days. My house had no insulation in the walls- to very less in the attic. After the insulation my Heat as well as Cold is retained inside the house. Heat turns on once in a 24 Hr cycle vs multiple times in an hour previously. If you are thinking of in wall insulation, it's totally worth it. The quote was the most competitive and they were very flexible.

I was initially impressed with what seemed like a thorough and well-considered estimate. It felt…read morelike the team really evaluated my attic and cooling needs. The addition of two QuietCool fans also seemed like a major plus, as I was already familiar with the product and expected it would significantly help with cooling. When it came to the insulation work, I was very pleased. The crew did an excellent job removing the old insulation and installing the new. They worked efficiently, protected my floors well, and ensured that no insulation debris entered the living areas. That part of the job was handled professionally. However, I was less impressed with the radiant barrier installation. This may partly be due to a misunderstanding on my end, as I expected a different type of material, but the end result did not meet my expectations. The biggest issue, unfortunately, was the installation of the fans. At best, it was very poorly executed. The fans are 16" units with 12" duct openings, yet they were installed directly against the gables, which severely restricts airflow. Proper installation should have included a box or shroud to help direct airflow effectively through the fans. Because of this poor airflow, the fans do not cool the attic--in fact, they appear to make things worse. I can actually watch the temperature on the thermostat increase when the fans are turned on. I reached out to my representative multiple times, but the response was disappointing. I was told they could not take the fans back, and when I asked why the attic temperature increases when they are running, I was told there was no explanation and nothing further could be done. As temperatures continue to rise, I'm left frustrated that I spent $1,200 on two fans that perform the opposite of what was promised, with no meaningful support or resolution offered. UPDATE: After posting my initial review, I was contacted by both the project manager and the owner. I reiterated the reasons for my frustration, explaining that my review reflected my honest impression of what I saw as a lack of clear communication and effective management of the project and customer expectations. The project manager apologized for the communication breakdown and asked if I would be open to giving them an opportunity to make things right. A technician was then sent out, and he took the time to fully understand the issue, carefully examine the installation, and make several adjustments to the original work. He believes these changes will help improve airflow in the attic. Since my attic has some unique characteristics, he also provided helpful suggestions for additional ways to improve cooling and airflow--something I feel should have been addressed during the initial planning stage of the project. Whether these changes will result in significant improvement remains to be seen; I'll have a better sense once the weather warms up. I do appreciate the follow-up and the willingness of the project manager to reach out and try to make things right, and I have updated my review accordingly. That said, I want to be clear that the increase in my rating is largely due to the technician and the time he invested in evaluating the full situation, as well as both implementing and proposing thoughtful solutions.
