Chattanooga's Commercial HVAC Specialists
From rooftop units to walk-in coolers, Maintenance Plus keeps Chattanooga's restaurants, retailers, and commercial facilities running — no matter what the Tennessee weather has in mind.
Maintenance Plus handles the systems that keep your business profitable — from the kitchen exhaust hood to the walk-in freezer, we service it all.
Rooftop units, split systems, and central HVAC for offices, retail spaces, and facilities of all sizes throughout the Tennessee Valley.
Walk-in coolers, walk-in freezers, reach-in units, display cases, and ice machines — our refrigeration specialty sets us apart from general HVAC companies.
Purpose-built expertise for food service. We understand the demands of a commercial kitchen — the heat load, the ventilation codes, the downtime cost.
A planned maintenance contract is the single best investment a commercial operator can make. Fewer breakdowns, longer equipment life, lower energy bills.
Proper ventilation and air quality is non-negotiable for food service and retail. We design and service systems that keep your air clean and compliant.
Smart thermostats, building automation, and energy audits to reduce operating costs — often the fastest way to improve your bottom line.
When your walk-in goes down, every hour costs money. We prioritize refrigeration calls.
Three decades in commercial HVAC and refrigeration means we've seen every scenario — and fixed all of them. Maintenance Plus is a Chattanooga company that treats your equipment like it's our own.
An ounce of prevention. PM contracts mean priority scheduling, reduced repair costs, and systems that outlast their warranties.
Our walk-in cooler went down on a Friday night before a big weekend. Maintenance Plus had a tech on-site within three hours and had us back up by midnight. That kind of response is why we've been with them for eight years.
We have six retail locations and Maintenance Plus manages all our HVAC and refrigeration under one contract. They know our systems, our managers know their techs by name, and we haven't had an unplanned outage in two years.
When we built our second kitchen, Maintenance Plus designed the whole ventilation system from scratch — hoods, makeup air, the walk-in layout. They understand food service in a way that most HVAC companies simply don't.
Whether you need emergency refrigeration repair at midnight or want to discuss a maintenance contract for your facility, we're ready to help. Our team answers the phone 24 hours a day.
