A failed or worn unit
We review the fault, remaining condition and repair option alongside replacement. You can then compare what each option solves for the building.

Rooftop Unit Installation & Replacement in NYC & Northern NJ
Replace a worn rooftop unit or plan a new commercial RTU installation with Airplex in NYC and Northern New Jersey. We connect equipment selection, roof conditions and building needs into one defined mechanical project.

Equipment-specific service
The service decision
A rooftop replacement is more than a new cabinet on the roof
The right project addresses the space served, the existing roof connection, utilities, ductwork and controls. Airplex helps you compare the full installation scope, including what can be reused and what must change. That makes equipment quotes easier to compare and helps expose missing work before the installation is scheduled.
Site coordination
Service that fits the building
NYC and Northern NJ roof access, loading space and occupied-building schedules can shape a rooftop project. Airplex discusses these constraints as part of the installation plan, not after the equipment is ordered.

UNDERSTAND THE PROBLEM
Decide what the new unit needs to solve
A replacement should fit today’s building, not simply repeat an old equipment choice.
Persistent comfort problems
A larger unit is not an automatic answer to uneven rooms. Air delivery, controls and the building load need to be part of the project review.
Changed tenants or room use
A restaurant, office and storage area can place different demands on HVAC. New occupancy and operating hours should be considered before selecting equipment.
YOUR SERVICE OPTIONS
Compare the complete installation scope
These items often explain why two RTU proposals differ.
Roof curb and duct connections
We review the existing curb and openings against the proposed equipment. The installation plan identifies connection changes and coordination with the party responsible for related roof work.
Power, fuel and controls
Existing services and controls need a compatibility review. Separate mechanical work from any electrical, fuel or building-platform work assigned to another trade.
Removal, lifting and access
Equipment delivery and removal affect the work sequence and cost. The roof route, staging and any lift arrangements need to match the property.
PLAN THE NEXT STEP
Make completion and handover clear
The project should leave the building team able to operate and maintain the installation.
Plan the interruption
Discuss the affected spaces and expected service interruption for the agreed work. Temporary arrangements, if needed, are a separate decision rather than an automatic inclusion.
Review operation after installation
We include the agreed startup and relevant operating checks in the installation work. Outstanding items and any follow-up responsibilities are made clear to the building team.
Keep the final records
Retain equipment details, available manuals and the maintenance requirements. Clear records make future service easier and distinguish the new installation from removed equipment.
PRICING FACTORS
What affects the cost?
The total includes more than the unit: removal, lifting, roof connections, utilities, controls and startup can affect the price. Compare proposals using the same equipment and included work, with exclusions stated clearly.
Select for the current building requirement
The existing unit provides useful information, but its label is not a complete specification for the replacement. Occupancy, layout, ventilation and operating hours may have changed since it was installed. Repeating the old capacity without reviewing those changes can reproduce an old limitation.
A suitable selection considers the heating, cooling and air-delivery duties together. More nominal capacity is not automatically an improvement if distribution or control is the real issue. The proposal should explain whether the project restores the original arrangement or changes it to meet a revised building need.
The roof connection is part of the equipment decision
A rooftop unit connects to more than power and a thermostat. The support or curb, duct openings, weathering, utilities and service access influence the installation. A new unit may require adapters or alterations even when it occupies roughly the same footprint.
These interfaces help explain why equipment-only prices are poor comparisons. Ask the project scope to identify retained connections and surrounding work. Structural or other professional review may be needed for the specific project; its responsibility should be assigned rather than implied by the selection of a cabinet that appears to fit.
Choose the functions the replacement must provide
Heating and cooling are only part of the operating brief. Outdoor-air control, scheduling, zoning and communication with existing controls can affect the installed result. A replacement that omits a required function is not equivalent simply because its rated capacity matches.
Define how occupants and facility staff will operate the system after the project. If the building has separate zones or a management system, the new equipment needs an appropriate integration plan. The owner should understand which controls remain, which change and who is responsible for the completed operating sequence.
Plan the changeover and the proof of completion
Removal, lifting, installation and reconnection need a coordinated sequence, with the affected building service identified. The practical schedule depends on the site and equipment, so a project should not be sold on a universal one-day assumption. Surrounding work and restoration belong in that sequence.
At handover, the project should show the selected equipment, completed connections and the relevant functions checked. Where a condition cannot be fully demonstrated at the time, record the limitation and follow-up responsibility. A successful startup is important, but the purpose of the installation is the intended operation of the building system.
Questions before you request service
Rooftop Unit Installation & Replacement questions
Can the new rooftop unit use the existing curb?
Possibly, but dimensions, connections and condition need review. The proposal should identify whether the curb is reused, adapted or replaced, along with responsibility for related roof work.
Should we choose a larger rooftop unit?
Only if the building review supports it. Comfort complaints can have causes other than insufficient capacity. Equipment selection should reflect the current load and air-delivery system rather than a guess.
What should be reviewed before a replacement rooftop unit is ordered?
Establish the current duty and the installation interfaces: support, duct connections, utilities, controls and removal or lifting arrangements. Identify any surrounding work and professional review required for the project. Resolving those items before ordering helps avoid selecting equipment whose installation assumptions do not match the building.
Can a replacement RTU connect to our existing building controls?
It may, through a supported arrangement, but compatibility and the desired operating functions need review. Specify what the building system must monitor or command and which controls remain. The project should assign configuration and verification responsibilities so a physical connection is not mistaken for a complete working integration.
