Make-up air unit
maintenance contracts
for Manhattan
kitchens and buildings that need airflow
Custom-scheduled MAU inspections and tune-ups engineered for Manhattan's restaurants and commercial buildings. Keep exhaust systems balanced, occupants comfortable, and your LL97 exposure in check.

Our Make-Up Air Unit Maintenance Services in Manhattan
Comprehensive maintenance planning designed to catch failures before they happen — keeping Manhattan's MAU systems balanced year-round.
Scheduled Seasonal Tune-Ups
Custom-timed inspections ahead of Manhattan's summer and winter demand swings, so your make-up air unit is ready before your kitchen or building needs it most.
Priority Emergency Response
Contract holders move to the front of the dispatch queue. If a covered unit does go down, our certified technicians reach your Manhattan site typically within 4 hours.
Belt, Filter & Burner Service
Routine replacement and inspection of wear components — belts, filters, and burner assemblies — that cause the majority of unscheduled MAU failures when neglected.
Controls & Automation Upgrades
Pair your MAU with 75F or Honeywell smart controls to tie exhaust and make-up air together automatically, reducing energy waste and improving comfort.
LL97 Compliance Optimization
NYC's Local Law 97 targets buildings over 25,000 sq ft — exactly where most Manhattan MAU systems live. Ongoing maintenance is one of the most cost-effective ways to hold down your carbon exposure.
Documented Service Reporting
Every visit ends with a detailed inspection report on file — documentation your building manager, insurer, or compliance filing needs, ready whenever it's requested.
From first inspection to year-round coverage
One partner handles every step. Here's how we set up your maintenance contract.
Building & equipment assessment
A certified technician walks your Manhattan property, documenting your make-up air unit's age, condition, and service history to build an accurate maintenance baseline.
Custom maintenance plan design
We build a visit schedule and scope around your building's exhaust load, kitchen equipment, and NYC seasonal demands — not a generic one-size-fits-all package.
Fixed-price contract proposal
You receive a clear, itemized annual price before signing — no hourly surprises, no hidden line items added mid-contract.
Scheduled service & reporting
Technicians arrive on schedule for every visit, performing inspections to OEM specifications and leaving a detailed report behind after every stop.
