Commercial HVAC Preventative Maintenance Contracts in NYC
Irving Haase specializes in commercial HVAC preventive maintenance for buildings throughout Manhattan, Queens and Brooklyn. Regular professional maintenance keeps your equipment performing as intended while supporting occupant comfort and system efficiency.

Checklist
What a Preventive Maintenance Visit Covers
Each task targets a known failure point, so problems are caught before they escalate. Depending on the equipment, a visit typically includes:
Air filter inspection and replacement
Evaporator and condenser coil cleaningDrain pan and condensate line clearing
Belt and pulley condition checks
Refrigerant level monitoring
Thermostat calibration and controls verification
Electrical connection inspection and tightening
Fan motor and blower performance checks
Most commercial systems are maintained two to four times per year: in spring before cooling season, in fall before heating season, and more often for high-use equipment or systems serving occupied tenant spaces and server rooms.
Are you tired of having your HVAC equipment fail right when you need it most each year? It's time to stop guessing about the condition of your equipment and whether it will work. Professionally maintained equipment gives you the most reliability and efficiency, and gives you and your staff the peace of mind that the building will be comfortable all year long.
Maintenance Agreements Built Around Your Equipment
At Irving Haase & Co., Inc., every Preventive Maintenance Agreement is customized to the individual building and the equipment in it. That lets us maintain each unit to the manufacturer's specifications, which maximizes equipment lifespan and reduces unscheduled downtime and added expenses. We maintain the systems NYC commercial and luxury multifamily buildings rely on, including rooftop and packaged units, VRF systems, water source heat pumps, PTAC units, CRAC units, split systems and cooling towers.
The Tasks That Deliver the Most Value
Coil Cleaning and Airflow
Condenser and evaporator coil cleaning is the single most impactful preventive maintenance task for commercial systems. Fouled coils reduce heat transfer, raise head pressure and force compressors to run hotter, which accelerates wear on every major component. Clean coils restore rated capacity, shorten run times, lower energy use and help protect indoor air quality.
Electrical Diagnostics and Controls
Checking capacitors, contactors, wiring terminals and control boards catches the components most likely to fail without warning. A failed contactor costs a fraction of a burned-out compressor. Controls review keeps thermostats, schedules and setpoints calibrated, so equipment runs when it should and cycles less.
Refrigerant Management
We check system charge, inspect for refrigerant leaks and document refrigerant additions in line with EPA Section 608 requirements. Those records also support planning for aging equipment as the industry moves to newer refrigerants such as R-454B.
Why NYC Property Managers Invest in Maintenance Agreements
Less downtime in occupied buildings. In a fully occupied commercial or luxury multifamily building, an HVAC failure means tenant complaints and lost productivity. Scheduled maintenance finds worn components before they fail during peak summer and winter loads.
Lower operating costs and longer equipment life. Clean coils, correct refrigerant charge and unrestricted airflow keep energy use down. When equipment runs within the manufacturer's normal operating specifications, it lasts much longer, lowering the total cost of ownership.
Predictable budgets. For property managers overseeing one building or a portfolio, a maintenance agreement turns unpredictable repair spending into a plannable line item for reserve and capital planning.
