Therm-Con in Chattanooga: Commercial HVAC and Building Systems for Industrial Clients
Therm-Con is a licensed mechanical contractor specializing in commercial HVAC design, installation, and service for industrial and institutional facilities across Chattanooga and the surrounding region. Unlike residential HVAC providers, the company focuses on larger-scale systems serving manufacturing plants, warehouses, hospitals, and office complexes where climate control, air quality, and equipment reliability directly affect operations.
What Therm-Con actually does
Therm-Con handles the full lifecycle of commercial heating, ventilation, and air conditioning systems. This includes load calculations for large buildings, ductwork design and fabrication, equipment selection and installation, maintenance contracts, and emergency repairs. The company also works on building automation systems, energy efficiency upgrades, and code compliance for new construction and renovations. Unlike general contractors who may call in HVAC as a subcontractor, Therm-Con manages these systems as its core business, which matters for clients who need deep expertise in systems that run 24/7 and cannot afford downtime.
Services and pricing structure
Therm-Con charges differently depending on the job type. New system installation pricing depends on building size, ductwork complexity, and equipment selection. A typical light commercial rooftop unit installation (2,000 to 5,000 square feet) ranges from $8,000 to $15,000 for equipment and labor combined, though larger or more complex projects cost more. Maintenance contracts for commercial clients typically run $150 to $400 per month depending on system size and service frequency. Emergency after-hours service carries an additional dispatch fee of $200 to $300 on top of labor rates. Rates should be confirmed directly with the company, as commercial pricing varies significantly by scope.
Maintenance plans are worth considering if your facility runs continuously. A quarterly or semi-annual tune-up catches refrigerant leaks, checks electrical connections, and cleans coils before they cause shutdowns. For facilities that cannot tolerate downtime, a preventive maintenance contract often pays for itself by preventing emergency calls.
How Therm-Con compares to other Chattanooga options
Therm-Con competes primarily with larger mechanical contractors like Comfort Systems USA and regional firms that also serve industrial clients. Comfort Systems is a national chain with broader service capacity and faster response times in some cases, but higher overhead often means higher pricing for standard jobs. Smaller local HVAC shops typically focus on residential work and lack the equipment and expertise for large commercial systems.
Choose Therm-Con if your facility needs a contractor who specializes in commercial systems and understands the compliance requirements of industrial or institutional buildings. Choose a larger firm like Comfort Systems if your project is part of a bigger construction contract where coordinating multiple trades matters more than specialized HVAC expertise. Choose a residential HVAC company only if you are retrofitting a small office or retail space where residential-scale equipment applies.
Who should contact Therm-Con and who should not
Therm-Con suits manufacturing plants, warehouses, hospitals, schools, multi-tenant office buildings, and any facility where HVAC failure affects revenue or safety. The company also works well for clients replacing aging systems where load calculations and energy modeling justify the investment.
Therm-Con is not the right fit for single-family homes or very small retail spaces; residential contractors are cheaper for those jobs. It is also not ideal if you need a general contractor to manage multiple building trades; in that case, hire Therm-Con as a subcontractor through your general contractor.
What the first contact involves
Contact the company with your building's square footage, current system age and type, and the problems you are experiencing (temperature swings, high utility bills, equipment noise, or failure). Therm-Con will schedule a site visit, which typically includes an assessment of existing ductwork, equipment condition, and building layout. If you need a new system, the company performs a load calculation using your building's insulation, window area, occupancy, and internal heat sources. From there, the contractor provides a written proposal outlining equipment specifications, labor scope, timeline, and cost. For maintenance contracts, the company outlines what is included in each service level.
Hours, location, and how to reach them
Therm-Con maintains a service office in Chattanooga with dispatch available during business hours and emergency service available outside standard hours. Business hours typically run Monday through Friday, 8 a.m. to 5 p.m.; emergency calls are available 24/7 for contract customers. Contact the company directly by phone to discuss your project and confirm availability. Parking and on-site logistics are handled based on your facility's layout.
Therm-Con fills a specific role in Chattanooga's commercial building ecosystem, handling the mechanical systems that larger facilities depend on daily. Its focus on industrial and institutional work means it brings experience that a general HVAC company cannot match.
