🌡️

Commercial Heating & Cooling

Rooftop units, split systems, and central HVAC for offices, retail spaces, and facilities of all sizes throughout the Tennessee Valley.

❄️

Commercial Refrigeration

Walk-in coolers, walk-in freezers, reach-in units, display cases, and ice machines — our refrigeration specialty sets us apart from general HVAC companies.

🍽️

Restaurant Kitchen Systems

Purpose-built expertise for food service. We understand the demands of a commercial kitchen — the heat load, the ventilation codes, the downtime cost.

📅

Preventive Maintenance Contracts

A planned maintenance contract is the single best investment a commercial operator can make. Fewer breakdowns, longer equipment life, lower energy bills.

💨

Indoor Air Quality

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.

Building Controls & Energy

Smart thermostats, building automation, and energy audits to reduce operating costs — often the fastest way to improve your bottom line.

What Chattanooga Businesses Say

★★★★★

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.

MR
Marco R.
Restaurant Owner · Downtown Chattanooga
★★★★★

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.

ST
Sandra T.
Regional Facilities Manager
★★★★★

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.
