Providing Innovative Solutions



More than 20 Years of Providing World-Class Innovative Solutions to Our Clients

Founded in 2002 on the fundamentals that all people are valued and should be treated with humility and respect, ACIS was created. ACIS is a proven, world-class commercial mechanical services provider. ACIS strives for excellence by operating with strong core values, engaging with customers to develop a trusted partnership, and providing access to the most talented technicians in the industry.

The company was founded by Mike Nichols and Kevin Self, two lifelong friends who dreamed of owning an elite HVAC company. It has been a story book tale of events since inception. They were pleased at how easily they were accepted in such a large market primarily because so many of their customers shared the same core values and principles.

ACIS began with a vision of providing comprehensive commercial and industrial HVAC services, with a strong focus on preventative maintenance and emphasis on energy savings. Through the years, we have expanded our force in the industry to include equipment design and replacement, plumbing, boilers, retrofits, building automation systems, and electrical service and projects.

What They Are
Saying About Us

The ACIS tech that helped us out did a very good job and was very thorough.

    Tracy Stegall


    I just wanted to give Pat with ACIS kudos for working so hard at the building helping us keep our system running and teaching me what I need to know about Commercial HVAC systems. He is great at what he does and knows this system here inside and out. I have learned so much from him and probably would never have learned this much had it been someone else here as our contractor. Give him a pat on the back and tell him he is an essential employee for ACIS and the customers you have.

      Thank you for hiring such a great group of techs. Matt, Zack, Al, even Wally, have worked really hard all week to get our weather damage repaired and all of our residents back to having HVAC. They just got the last resident VRF put back together and it is cooling. Tomorrow they will work several of the VRF’s where they borrowed boards and such to get the others up and running. We appreciate all of the ACIS groups, from your crackerjack Dispatch folks to the plumbers and even unitary! But the VRF techs have really shined for us over the years and we appreciate their hard work and commitment.

        I wanted to say thank you for sending Edgar for our plumbing needs. Edgar has resolved many of our main water leaks in our irrigation in 2 of our sites. Last night he made a repair that was leaking .5 gallon/sec in the ground. I also want to say that I have seen nothing but the best craftsmanship in plumbing installation by Edgar. His pride in his craft shows and represents ACIS very well.  He stayed after hours and got the repairs completed so we can continue to trouble shoot the irrigation system. 5 Star award to Edgar. Thanks for your help.
