The Journey of Atticman

    2017

    Where It All Started

    Atticman Heating and Air Conditioning began in June 2017 when Mario and Senior purchased a 1997 Ford F-150 off Craigslist for $1,500 and started insulating attics across Sacramento. Working out of Mario's grandmother's garage, the two hustled job after job, building a reputation through hard work and word-of-mouth referrals from satisfied customers.

    2019

    Building the Foundation

    What started as a two-person operation began to take shape as a real business. Mario met Georgia, who left her career to help transform Atticman from a truck-and-tools operation into a legitimate company. The team also welcomed its first official installer, Edgar, and purchased the first Atticman van — setting the stage for serious growth.

    2021

    A Place to Call Home

    Atticman reached a major milestone by securing its first official office and warehouse space, giving the team a place to truly call home. What began as a small operation run out of a garage and home office had evolved into a fully functional headquarters, built to support an expanding team and increasing demand. Along the way, Atticman strengthened its roots in the Sacramento community, earning trust through a consistent commitment to quality service and a customer-first approach.

    2022

    Built to Serve Better

    Atticman took another step forward by expanding into a second warehouse next door, allowing the team to grow its inventory and keep essential materials on hand. By stocking parts that would typically require long lead times, Atticman was able to serve customers faster and more efficiently without compromising on quality. More importantly, this chapter was defined by a deep investment in building a strong, values-driven culture—bringing together a team committed to craftsmanship, reliability, and delivering a consistently exceptional experience for every customer.

    2024

    Elevating the Standard

    In 2024, Atticman continued to make significant investments in both our team and our future. As SMUD’s #1 contractor partner, we expanded our workforce, launched Atticman Academy, and transitioned into a 10,000 sq. ft. facility designed for excellence.

    Our headquarters now features a dedicated training and meeting space, a gym, and an outdoor area for team breakfasts and BBQs—creating an environment where continuous growth is part of our culture.

    With over 2,100 five-star reviews, Atticman continues to redefine what homeowners expect from an HVAC company..

    2026

    A Trusted Name in Sacramento

    By 2026, Atticman had established itself as a reliable, recognizable brand across the greater Sacramento region—known for consistent service, honest work, and an unwavering commitment to quality. With the opening of satellite locations in Folsom, Roseville, and Elk Grove, the team was able to better serve homeowners throughout the region while staying true to its locally owned and operated roots. Built on a reputation for high-quality installations that stand above the rest, Atticman continues to invest in its people, its processes, and its community—focused on being a company customers can count on for years to come.

    Professional, extremely knowledgeable and very friendly. They explained everything to me in detail and answered all of my questions. Both Alejandro & Jorge were phenomenal!!!

    I had new installation added to my entire attic. The technicians were on time, extremely clean throughout the whole day and wonderfully friendly. I hated to see them leave.

    Thank you Atticman for always performing an outstanding service! I will always recommend you and will always use your services.

    Sincerely

    I’ve had several bad experiences with contractors and their employees so this review should show all who read it these guys are fantastic. Their salesman were friendly and kind. They were not “pushy”. The installers put in a good 8 hours and were quiet, quick, and they cleaned up everything. They showed me the system, explained it all to me and the most significant comment I’d like to add they closed my moms bedroom door for her(she’s bedridden) and they didn’t work on anything until noon or later. They even put up with our goats getting into their truck and running by them, many times. They were outstanding installers. Very pleased with the atticmen

    Update 08/14/2026: These guys are great. Had them out for a new a/c heater roof combo install and all they've done is great work. Whenever I have a tech out for service they're timely and respectful. Only good things to say about Mario's atticman heating and air and the people he's brought on throughout the years (been with them since 2019).
    Have had Atticman out 8 times over the past 3-4 years. They show up within their service window, shoot straight with their customers, and have competitive pricing (especially compared to some of the bigger hvac companies). Give them a try, my family and I haven't hired another company since we've had Atticman out for services/installs.

    Kris came for a final inspection and the county inspector came by for the final inspection. Both gave a big thumbs up on the installation and vent work. All went smooth.

    We had a great experience with Jacob from Atticman! He came out for a service call today. He was personable, professional, and knowledgeable. He took the time to thoroughly explain our system, how it operates, and how we should use it properly. He answered all of our questions and made sure we understood everything before he left. We truly appreciated his patience and excellent customer service. Thank you, Jacob🤗

    We had a concern with our attic HVAC unit and had an appointment scheduled late in the day that ended up being early evening. Josiah was our technician, and he went above and beyond to reassure me that the equipment was operating properly and safely. Even though it was late, he took his time thoroughly inspecting everything and answering my questions. I really appreciated his patience, professionalism, and attention to detail. It was reassuring to have someone who genuinely took the time to make sure everything was okay. Atticman really strives to maintain a five star reputation.

    Jacob came out for some warranty work today. He worked through an unexpected challenge and stayed late to make sure the repairs were done properly. I truly appreciated his dedication to getting the job done right.

    Original post:
    We had new heat pumps installed along with some ducting optimizations to fix airflow issues between bedrooms. Kobe, Mike and team did an exceptional job as it was a challenging install with a few surprises along the way. They strived to ensure everything was done the best way possible and we are very happy with the end result.

    The office representative was incredibly patient and helpful. She found an opening where I could get a service call the same morning! The technician, Jaspreet, was nothing short of top-notch. Knowledgeable, professional, and super fast! Atticman is now my go-to for HVAC.

    *This review is only for my tune-up appointment with a service tech, more services to come*

    Had Dillon come by my house to look at my entire ducting and HVAC system. Overall very educational, didn't come off sales-y, and gave me a candid take on what it takes to keep my system going on a little longer versus replacing. Thank you Dillon.

    I can’t say enough wonderful things about Zac and the team at Atticman! From the very beginning, they were professional, reliable, and incredibly respectful of our time.

    We were told they would arrive between 6:00 and 7:00 AM, and they even contacted us at 6:00 AM to let us know exactly when they would be arriving. They showed up right on time and got straight to work.

    They did a fantastic job from start to finish. They worked hard all day, paid attention to the details, and when they were finished, they cleaned everything up so well that you would hardly know they had been here.

    It is honestly unbelievable how great of a job they did today! Zac and the entire Atticman team went above and beyond, and we couldn’t be happier with the work.

    If you’re looking for a company that is dependable, hardworking, professional, and takes pride in their work, I highly recommend Atticman! Thank you, Zac and Fabian for an amazing job

    2nd Review is ⭐️⭐️⭐️⭐️⭐️

    I wanted to leave a follow-up review for Fabian and his team at Atticman because they once again did an absolutely fantastic job! They showed up right on time today and completely redid all of our ductwork. Removing the old ductwork was a huge, messy job, but this team handled it professionally from start to finish.

    What really impressed me was how much they cared about keeping everything clean. They continually cleaned up as they worked and made sure they left everything looking great when they were finished. They worked hard, paid attention to the details, and treated our home with respect.

    Fabian and his team went above and beyond, and we couldn’t be happier with the work they did. If you’re looking for a company that is dependable, professional, hardworking, and truly cares about doing the job right, I highly recommend Atticman
