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.

Dylan came out to service our 36-year-old HVAC system. He was on time very polite and courteous and knowledgeable of his job. Unfortunately our unit was not repairable. It was too old And seen better days. Dylan got us in touch with Kyle On the same day so we could go over pricing and different options. Kyle was very easy to work with, he explained everything very very well, now we wait for the new unit to come in and be installed. so far we are very happy with the service and would recommend them.

What a great company, fantastic customer service. Called to have them come out to check my system that was installed last year. Lexi scheduled me for the very next day. There seemed to be an issue with it not cooling effectively. Dustin came out in a very timely manor, he was even a little early. He found the problem and fixed it straight away! I can’t speak highly enough of their professionalism!

Before I start, I would like to thank the whole Atticman team.This is my 2nd review, after install. Eric and his team where awesome! They show up before I went to work, to explained everything they were going to do. They replaced ducting and vents, full havc system and put up new Co detectors. When I got home Eric explained how to use the system. I swear they cleaned the house cleaner then it was. 😃 I will tell all my friends to get a estimate from Atticman. Thank you everyone. Leigh A

David was exceptional. Service was scheduled maintenance. However, for many years we had considered adding an air scrubber, talked to people and did research but things just never seemed comfortable. Plus it's expensive. Today, I got into a detailed conversation with David and also called upon a friend who's more knowledgable. David adequately answered all questions he had and more and without pressure. I finally felt completely ok going forward with this due to David and also past dealings with Atticman. They are a small family company with old fashion customer service. Anne Chapman
