When commercial cooling fails, the complaints start immediately and the revenue impact follows. We repair, maintain, replace and install commercial air conditioning for offices, retail spaces, restaurants, medical suites and warehouses across North Jersey, including packaged rooftop units and split systems.
Heights is licensed and insured under NJ HVAC Lic. #197400 and brings 56 years of industry experience to commercial work. Our mechanical engineer handles load calculations and system design and our own crew does the electrical, so the job is coordinated by one contractor.
Hot Spots, High Bills And Systems That Cannot Keep Up
Commercial cooling problems are rarely uniform. One zone bakes while another is freezing, the front of a retail space is warm every afternoon, the conference room is unusable when it is full, or a server room creeps up on a hot day. Those are load and distribution problems as often as they are equipment failures, and they respond to a proper assessment rather than a parts swap.
The straightforward failures still hurt most. A rooftop unit down during a heat wave, a compressor that will not start, a refrigerant leak that has quietly been draining the system for months. What matters is getting an accurate diagnosis quickly and knowing whether you are looking at a repair or a replacement before you commit money to either.
What Our Commercial AC Service Includes
On a service call we check refrigerant charge and pressures, test compressors, contactors, capacitors and control circuits, inspect condenser and evaporator coils, verify airflow and filter condition, and check condensate drainage and economizer operation where present. Because control and electrical faults are so common in commercial equipment, we troubleshoot the wiring as thoroughly as the mechanical side.
For replacement and new installation we start with a load calculation that reflects how the space is actually used, including occupancy, lighting, kitchen and equipment heat. We then specify equipment, coordinate curb adapters and crane work for rooftop changeouts, handle permits and inspections, complete the electrical, and commission the system so airflow and capacity match the design.
Signs Your Commercial AC Needs Service
- System runs constantly but never reaches setpoint
- Noticeable hot and cold zones in the same space
- Breakers tripping when the unit starts
- Ice forming on refrigerant lines or the coil
- Water dripping from ceiling units or near air handlers
- Energy costs climbing with the same occupancy
- Musty smell coming from the supply vents
- Repeated refrigerant top-offs season after season

Our Commercial AC Process
Get the details
We ask about the equipment, the affected areas and how urgent it is, so the technician arrives with the right tools and parts.
Diagnose thoroughly
Refrigerant, electrical, controls and airflow all get checked. Repeated refrigerant top-offs usually mean a leak that should be found and repaired.
Present options with upfront pricing
You get the repair cost, the realistic condition of the equipment and, where it applies, a replacement comparison. No surprise fees.
Repair or replace with minimal disruption
We work around your business hours where we can, and coordinate permits, curb adapters and crane sets for rooftop changeouts.
Verify and document
We confirm charge, temperature split and airflow, record the work performed, and can set the equipment up on a maintenance schedule.
Commercial Cooling Options We Offer
Packaged rooftop unit service and replacement
The most common commercial setup in this area. We service, repair and change out rooftop units including curb adapters and crane coordination.
Commercial split systems
Condenser and air handler systems for offices, suites and smaller retail spaces where a rooftop unit is not practical.
Ductless and multi-zone systems
Zone-by-zone cooling for server rooms, converted spaces, offices within warehouses and tenant fit-outs.
Refrigerant leak detection and repair
Finding and fixing the leak instead of refilling the system every season, which is both cheaper and better for the equipment.
Preventive maintenance visits
Coil cleaning, electrical checks, charge verification and filter service before the cooling season, available as an ongoing program.

Commercial AC FAQs
Can you service our AC without closing the business?
In most cases yes. We schedule around your hours where the work allows it and keep occupied areas usable while we work.
My system keeps needing refrigerant. Is that normal?
No. Refrigerant is not consumed, so a system that needs repeated top-offs has a leak. We locate and repair it rather than selling you refrigerant every season.
Do you offer maintenance agreements for commercial AC?
Yes, as an option. We scope the visits to your equipment list and your operating season rather than applying a fixed package.
What if the system fails after hours?
You reach a live person any time you call 201-245-7772. They take the details and book you into the next available appointment.
How long does a rooftop unit replacement take?
Most straightforward changeouts are completed in a day once the crane and curb adapter are arranged. We give you a firm plan before scheduling.
