Question 1

What types of commercial HVAC systems do you service?

Accepted Answer

We service the full range of commercial HVAC equipment installed across NYC and Long Island, including rooftop units (RTUs), split systems, VRF/VRV systems, chillers, cooling towers, commercial boilers (steam, hot water, and condensing), make-up air units, packaged units, heat pumps, exhaust systems, and building automation/BAS controls. Our technicians are trained across all major commercial manufacturers and handle service, repair, replacement, and new installation.

Question 2

Do you work on RTU rooftop units?

Accepted Answer

Yes — rooftop units are one of our core specialties. We service, repair, and replace single-zone and multi-zone RTUs from Carrier, Trane, Lennox, York, Daikin, AAON, and others. Typical work includes compressor and condenser repair, economizer service, gas heat section repair, belt and bearing replacement, refrigerant leak diagnostics, and full RTU change-outs with crane lifts coordinated by our team.

Question 3

Can you handle VRF (Variable Refrigerant Flow) systems?

Accepted Answer

Absolutely. VRF/VRV is a growing share of our commercial workload. We design, install, commission, and service VRF systems from Daikin, Mitsubishi, LG, and Samsung — including heat-recovery configurations for mixed-use buildings. Our techs are trained on branch controllers, refrigerant piping, and proprietary controls, and we hold the EPA Section 608 certifications required to work with VRF refrigerants.

Question 4

What is the difference between a chiller and a boiler system?

Accepted Answer

A chiller produces chilled water that's circulated through air handlers or fan coils to cool a building, while a boiler produces hot water or steam for heating. Large commercial buildings often run both — chillers in summer for cooling, boilers in winter for heat — and rely on pumps, valves, and controls to distribute that water through the building. We service both sides of the plant, including chillers, boilers, pumps, controls, and piping accessories.

Question 5

Do you offer preventive maintenance contracts?

Accepted Answer

Yes. We offer flexible preventive maintenance agreements (PMAs) for property managers, GCs, and building owners — typically quarterly or semi-annual visits with detailed equipment reports, filter changes, coil cleanings, combustion analysis, refrigerant checks, and priority emergency response. Contracts are scoped to your equipment list and budget, and PMA clients get priority dispatch and discounted labor rates on repairs.

Question 6

What areas do you serve?

Accepted Answer

We serve the greater NYC Metro area — Manhattan, Brooklyn, Queens, the Bronx — plus all of Nassau County and western Suffolk County on Long Island. Our office is at 264 W 40th St in Midtown Manhattan, and we dispatch technicians across the five boroughs and Long Island daily.

Question 7

How fast can you respond to an emergency?

Accepted Answer

For true emergencies — no heat, no cooling in occupied space, refrigerant leaks, flooding, gas smells — we target a 2-to-4-hour on-site response window in our core service area, and same-day response for most commercial calls. PMA contract clients are dispatched first. Call (332) 600-4640 and our dispatcher will give you an honest ETA based on current load and your location.

Question 8

Do you charge extra for after-hours emergency service?

Accepted Answer

After-hours, weekend, and holiday rates are higher than standard business-hours rates — this is industry standard and reflects the cost of pulling a technician outside normal scheduling. We're transparent about the rate before we dispatch, and our PMA contract clients receive discounted emergency labor rates as part of their agreement.

Question 9

Are you available on weekends and holidays?

Accepted Answer

Yes. We staff a 24/7 emergency line every day of the year, including weekends and major holidays. Routine, non-emergency service is scheduled Monday through Friday, with Saturday available by appointment and Sunday reserved for emergencies only.

Question 10

Do you service nationwide projects?

Accepted Answer

Our direct service footprint is the NYC Metro and Long Island region. For multi-site clients with locations outside that area, we can coordinate equipment specs, manage warranty work through manufacturer service networks, and support facilities teams remotely — but on-site labor outside our region is handled by partner contractors, not our own crews.

Question 11

Do you offer free estimates?

Accepted Answer

Yes — estimates for new installations, system replacements, and project work are free. A site visit is usually required so we can verify equipment specs, access, and existing conditions before quoting. For diagnostic and repair calls on existing equipment, a standard service-call/diagnostic fee applies, which is credited toward any repair you approve.

Question 12

How do I request a quote?

Accepted Answer

The fastest path is to call (332) 600-4640 or fill out the form on our Contact page with your address, equipment type, and a short description of the project. For larger jobs (chillers, boilers, full system change-outs, VRF design), we'll schedule a walk-through with one of our project managers and follow up with a written scope and pricing within a few business days.

Question 13

Are you insured and certified in New York?

Accepted Answer

Yes. Com+ Mechanical is fully insured to perform commercial HVAC and refrigeration work in New York State and New York City, and our technicians are EPA-certified, NATE-certified, and factory-trained. We carry general liability and workers' compensation coverage that meets or exceeds the requirements of property management companies, REITs, and general contractors we work with. Certificates of insurance are available on request.

Question 14

What brands and manufacturers do you work with?

Accepted Answer

We service every major commercial HVAC manufacturer, including Carrier, Trane, Lennox, York, Daikin, Mitsubishi, LG, AAON, Rheem, Bosch, Weil-McLain, Burnham, Lochinvar, Aermec, Multistack, and more. We're brand-agnostic on repair and brand-strategic on installs — we'll recommend the equipment that best fits your building, budget, and long-term operating cost.

Question 15

How do I schedule preventive maintenance?

Accepted Answer

Call (332) 600-4640 or email info@complusmechanical.com with a quick description of your equipment (type, quantity, location, age if known). We'll set up a walk-through, build a PMA scope tailored to your equipment list, and propose a visit cadence — typically quarterly for critical equipment and semi-annual for standard systems. Once signed, we schedule visits in advance and send a written report after each one.
