Three decades of commercial HVAC and refrigeration in Chattanooga. Built on honest work, technical expertise, and the understanding that when your system goes down, your business goes down with it.
Maintenance Plus was built around a simple idea: commercial clients deserve the same expertise, urgency, and honesty in their HVAC service that they'd expect from any other business partner.
We started with restaurant and food service clients — the most demanding environment in commercial HVAC — and built our reputation on showing up fast, diagnosing accurately, and fixing things right the first time. Word spread, and our commercial client base grew to include retail, office, healthcare, and industrial facilities across the Tennessee Valley.
Our commercial refrigeration specialty grew naturally from the food service work. Walk-in coolers and freezers, display cases, ice machines — refrigeration equipment that the big HVAC companies treat as an add-on, we treat as a core competency. It's one reason our clients tend to stay with us.
Maintenance Plus remains a Chattanooga company. Our technicians live here, our clients are our neighbors, and we're not going anywhere.
We don't split our attention between residential and commercial. Every technician, every training hour, every truck stock item is oriented around commercial and industrial systems.
Our average PM contract client has been with us for over seven years. We know their equipment, their facilities, and often their managers by name. That's not an accident — it's the goal.
We'll tell you when a repair makes sense and when replacement is the smarter call. We're not in the business of selling you equipment you don't need — or patching equipment that should be replaced.
From a one-truck operation to a full commercial HVAC and refrigeration company — built slowly, built right.
These aren't slogans — they're the principles that determine how we handle every service call, every estimate, and every client relationship.
Maintenance Plus serves commercial clients throughout the Tennessee Valley — from Chattanooga north to Cleveland and Dayton, south into North Georgia, and east into Bradley and McMinn Counties.
