Breakdowns at the worst time
July heatwave, packed restaurant, important client visit — that is exactly when aging systems fail
Repair costs exceed replacement
When you have spent $8K on repairs this year and the compressor is next — it is time to do the math

FAQ
Questions We Hear Every Day
Straight answers from engineers — no sales pitch.
What is commercial HVAC? It's climate control designed for non-residential or large mixed-use spaces — think rooftop package units, chillers, cooling towers, variable refrigerant flow systems, or large air handlers serving entire floors. Commercial HVAC operates at higher capacities (measured in tons rather than BTUs), uses three-phase power, and typically requires NYC DOB permits and sign-off from a licensed engineer.
How long do commercial HVAC systems last depends heavily on maintenance history and equipment type. A well-maintained rooftop package unit typically lasts 15–20 years; chillers can reach 25–30 years with proper water treatment and annual service. NYC buildings that skip preventive maintenance often see commercial systems fail at 10–12 years. Efficiency degradation and rising repair frequency are the clearest signals that replacement is cost-effective.
Where can I rent commercial HVAC systems? Specialty equipment rental companies like Aggreko, United Rentals, or Sunbelt Rentals supply temporary chillers, portable package units, and spot coolers for construction projects, data center emergencies, and event spaces. For NYC jobs, confirm the rental company can coordinate crane or hoist logistics for rooftop placement and verify that the temporary hookup meets Con Edison service requirements.
How often should commercial HVAC filters be changed depends on filter MERV rating, occupancy density, and proximity to construction. Standard MERV-8 filters in a lightly occupied office typically need replacement every 60–90 days; MERV-13 filters in high-occupancy or healthcare settings may need monthly checks. NYC buildings near active demolition or subway exhaust vents often see filters load up twice as fast as the manufacturer schedule suggests.
How does a commercial HVAC system work? A typical NYC rooftop package unit draws in outside air, conditions it through refrigerant coils and heat exchangers, then distributes that air through a duct network to VAV (variable air volume) boxes on each floor. Thermostats signal the VAV dampers to modulate airflow zone by zone. In larger buildings, a chiller plant produces cold water that circulates through fan coil units or air handlers on each floor instead.
