Install & Test
Licensed installation with hinge kit, wiring, and startup testing. Full written service documentation for your records.
Many Hermitage restaurants along Lebanon Pike and Old Hickory Blvd are operating exhaust fans that are well past their useful life. Severe vibrations, frequent belt snaps, and total motor failures are common in these aging strip centers. The older built-up roofing (BUR) and modified bitumen roofs add complexity — every fan installation requires careful curb adaptation and proper flashing to maintain roof integrity. We specialize in these retrofit challenges, fabricating custom curb adapters on-site when standard sizes don't fit the existing penetration.

What We Coordinate
We work with your general contractor, electrician, and fire suppression sub. One point of contact for the exhaust scope.
Hermitage Permits
We handle Metro Nashville Codes Department permit applications and schedule the final inspection with the Fire Marshal.
Since Hermitage is part of Metro Nashville, the Metro Nashville Fire Marshal holds aging infrastructure to modern NFPA 96 standards — frequently citing restaurants for missing hinge kits or inaccessible ductwork that was grandfathered in years ago. Many older Hermitage buildings have non-standard duct chases and limited rooftop access that require creative solutions. We assess every constraint during our free site survey and design the system to fit the building, including custom duct runs, modified roof penetrations, and upgraded electrical panels where needed.

Make-Up Air Unit Installation for Hermitage Kitchens
Your exhaust system can't function without balanced airflow. When MUA fails, doors slam, gas appliances backdraft, and fans lose efficiency.
Gas-Fired Heated MUA
Required for Tennessee winters. Direct gas-fired heating prevents freezing drafts and dangerous negative pressure. Properly sized units maintain comfortable kitchen temperatures year-round.
Untempered / Passive MUA
Budget fresh air supply for mild seasons and supplemental use. Belt or direct drive options. Effective when heating isn't required but airflow balance is still critical.
MUA Retrofit & Replacement
Upgrading undersized or failed units. We calculate CFM balance between your exhaust and make-up air to eliminate negative pressure and bring your system up to current code.

Lebanon Pike: Aging Infrastructure, Modern Standards
Many of Hermitage's busiest restaurants sit in established strip centers along Lebanon Pike where exhaust equipment is decades old. The Metro Nashville Fire Marshal now holds these older buildings to modern NFPA 96 standards, requiring hinge kits, access panels, and grease containment that didn't exist when the original systems were installed. We upgrade aging infrastructure to current code while working within the constraints of the existing building.
Old Hickory Blvd & Percy Priest Lake Area
The dining establishments along Old Hickory Blvd and near Percy Priest Lake see seasonal spikes in volume, particularly during summer when lake traffic drives up local dining demand. Summer heat also stresses aging rooftop motors. We install fans with adequate thermal margins and recommend preventive maintenance schedules to keep your system reliable during your busiest months.
TriStar Summit Medical Center & Institutional Kitchens
TriStar Summit and other institutional facilities in Hermitage operate cafeteria kitchens that require code-compliant exhaust systems designed for continuous, high-volume feeding operations. We install systems scaled for institutional throughput with strict compliance documentation required by healthcare facility management.
Hermitage Commercial Kitchen Compliance
The Metro Nashville Fire Marshal's Office has jurisdiction over Hermitage and enforces strict NFPA 96 standards. Inspectors frequently cite restaurants in aging buildings for missing hinge kits, inaccessible ductwork, or outdated grease containment. Every installation we do is built to pass modern Metro inspections on the first walkthrough — no grandfather clauses, no shortcuts.
Metro Water Services (MWS) rigorously enforces F.O.G. regulations to protect nearby Percy Priest Lake and the broader municipal water system. Rooftop grease runoff can result in substantial fines. We install comprehensive grease containment from the start so you're compliant before you open.

Frequently Asked Questions — Hermitage Installation
Can you install a modern exhaust system in an older Hermitage strip center building?
Yes. Retrofitting older Hermitage strip centers along Lebanon Pike and Old Hickory Blvd is a major part of what we do. We assess non-standard roof penetrations, aging electrical panels, and limited duct chases during our free site survey, then design a system that fits the building while meeting current NFPA 96 standards.
Does Hermitage fall under Metro Nashville Fire Marshal jurisdiction for exhaust permits?
Yes. Hermitage is part of Metro Nashville, so the Metro Nashville Fire Marshal's Office enforces NFPA 96 for all commercial kitchen exhaust systems. Metro inspectors hold aging infrastructure to modern standards. We handle all permits and coordinate the final inspection.
How much does it cost to replace an aging exhaust fan on a Hermitage restaurant rooftop?
A single fan replacement typically runs $1,500-$4,000 installed, depending on the fan size and whether your roof curb needs updating. Many older Hermitage buildings need curb adapter plates to accommodate modern fan dimensions. We include all necessary modifications in our quote — no hidden costs.
What happens to my older BUR roof when you install a new exhaust fan in Hermitage?
Older built-up roofing (BUR) and modified bitumen roofs common in Hermitage strip centers require careful fan installation. We use proper flashing, compatible sealants, and custom curb adapters to maintain your roof integrity. We also install grease containment to prevent any grease damage to the aging membrane.
Does summer heat near Percy Priest Lake affect exhaust system performance in Hermitage?
Yes. High ambient temperatures during Tennessee summers reduce fan motor cooling efficiency, which accelerates wear on older motors. We spec fans with adequate thermal margins and recommend preventive belt replacements before the summer season to avoid failures during your busiest months.
