About Us

Our primary service area covers eight counties in Northern and Central New Jersey: Morris County, Bergen County, Essex County, Monmouth County, Hudson County, Middlesex County, Union County, and Passaic County. We serve commercial and industrial clients throughout this region, from single-site businesses to multi-location portfolios. For emergency service, we respond throughout the service area 24 hours a day, 7 days a week.

No. We are exclusively a commercial and industrial HVAC, refrigeration, and energy management contractor. That specialization is intentional — commercial systems are fundamentally different from residential equipment in size, complexity, controls, refrigerant types, and code requirements. Our technicians are trained on commercial and industrial equipment, and our tools, vehicles, and inventory are set up for commercial work. This focus means you get a team that works on commercial systems every day, not a residential company trying to handle a commercial call.

KCG is a Service-Disabled Veteran-Owned Small Business (SDVOSB), certified through the U.S. Small Business Administration. This means the company is majority-owned and controlled by a service-disabled veteran of the U.S. Armed Forces. Our SBA certification (valid through January 2029). For government agencies and large corporations with supplier diversity programs, this certification means KCG qualifies for set-aside contracts and counts toward veteran-owned procurement goals.

We offer 24/7 emergency service and our dispatch operates around the clock. For critical situations — a heating failure in winter, a walk-in cooler down with product at risk, or a data center cooling alarm — we prioritize getting a technician on site within 2 to 4 hours across our eight-county service area. For urgent but non-critical calls, we typically respond same-day. Our full-service contract clients receive priority dispatch, meaning they move to the front of the queue.

We work on all major commercial HVAC and refrigeration brands including Trane, Carrier, Lennox, York, Daikin, Mitsubishi, Heatcraft, Bohn, and Copeland. We are not locked into a single manufacturer, which means we recommend the best equipment for each application and budget rather than pushing one brand. Our technicians carry factory certifications on multiple platforms and our parts inventory covers the most common components across brands.

KCG was founded in 1991 and has been operating continuously for over 34 years. Many of our client relationships go back over a decade. Our technician retention rate is well above the industry average — several members of our team have been with us for 10-plus years, which means the technician who services your building knows your equipment, your history, and your preferences.

Yes, and that is one of the reasons clients choose us. In buildings like grocery stores, warehouses, and pharmaceutical facilities, the HVAC and refrigeration systems are interconnected — changes to one affect the other. Having a single contractor who understands both systems eliminates the finger-pointing that happens when separate HVAC and refrigeration contractors each blame the other for a problem. Our technicians are cross-trained on both disciplines, which means faster diagnosis and more complete solutions.

Yes. Our dispatch line at 973-335-3884 is staffed around the clock, including nights, weekends, and holidays. Commercial HVAC and refrigeration emergencies do not wait for business hours — a heating failure at 2 AM in January or a walk-in cooler down on a Saturday night requires immediate response. Our on-call technicians are dispatched directly and carry the parts and tools needed for the most common emergency repairs. Full-service contract clients receive priority emergency dispatch.

We serve virtually every type of commercial and industrial facility: office buildings, retail stores, supermarkets and grocery stores, restaurants, warehouses and distribution centers, pharmaceutical and laboratory facilities, data centers, schools and universities, houses of worship, medical offices and clinics, manufacturing plants, and government buildings. Each building type has different HVAC and refrigeration requirements, and we design our maintenance programs around the specific needs and operating schedules of each facility.

Yes. KCG holds NJ HVACR Contractor License #19HC00737600, which authorizes us to perform all heating, ventilation, air conditioning, and refrigeration work in the state. We carry full general liability insurance, workers’ compensation coverage, and commercial auto insurance. We provide certificates of insurance to clients and property managers upon request — most of our clients require current COIs on file. Our licensing and insurance are maintained continuously and are never allowed to lapse.

Yes. We are happy to provide references from clients in your industry or building type. Many of our client relationships span over a decade, and our clients are generally willing to speak with prospective customers about their experience. We can also share our Google reviews, where we maintain a 4.6-star rating. We believe the best indicator of our work quality is what our existing clients say when you ask them directly.

We offer both. Most of our clients are on service contracts because they provide predictable costs, priority service, and better equipment longevity. We offer preventative maintenance (PM) contracts that cover scheduled inspections and routine maintenance, and full-service contracts that also include repair labor and most parts. For clients who prefer time-and-materials, we provide that option as well — you call when you need us and we bill for the work performed. We typically recommend starting with at least a PM contract because the data we gather during inspections helps us prevent failures and extend equipment life.

Our dispatch line operates 24/7 at 973-335-3884. After-hours and weekend calls are answered by our team — not an answering service — and dispatched to on-call technicians who are already in the field-ready rotation. Service contract clients pay pre-negotiated after-hours rates. Time-and-materials clients are billed at our standard after-hours rate. For emergencies that are critical to your operation — lost cooling in a data center, a freezer failure with product at risk, no heat in an occupied building during winter — we treat them as top priority regardless of when the call comes in.

Three things. First, technician consistency — our techs know your building, your equipment, and your history. You are not getting a different person every visit who has to start from scratch. Second, decision-making speed — when you need a repair approved or an equipment recommendation, you are talking to people who can make that call immediately, not waiting for regional office approval. Third, accountability — we are local, we are accessible, and our reputation depends on every single job. We do not have the luxury of losing a client and replacing them with the next name on a national account list.

Yes. We provide free on-site estimates for equipment replacements, new installations, and service contract proposals. The estimate includes a site survey, load calculation if needed, equipment recommendations with options at different price points, and a written proposal. For larger projects — full building HVAC replacements, BMS installations, or multi-phase retrofits — we provide a detailed scope of work and project timeline. There is no obligation and no pressure. Call us at 973-335-3884 or contact us through the website to schedule an estimate.

We prioritize hiring experienced commercial HVAC and refrigeration technicians with NJ journeyman or master licenses. All technicians carry EPA Section 608 Universal certification for refrigerant handling. We invest in ongoing training — manufacturer-specific courses, controls and BMS programming, and safety certifications. We also participate in veteran hiring programs and trade school partnerships to develop the next generation of technicians. Our retention rate is well above the industry average because we pay competitively, provide consistent work, and do not burn out our team with unreasonable on-call rotations.

Yes, and property managers are one of our largest client segments. We understand the unique challenges property managers face — multiple buildings, tenant comfort complaints, budget constraints, and the need for reliable documentation. We provide detailed service reports for every visit, maintain equipment inventories for each building, and communicate directly with on-site building engineers when applicable. Many property management companies use us as their preferred HVAC and refrigeration contractor across their entire NJ portfolio because they get consistent quality and a single point of accountability.

All equipment we install comes with the manufacturer’s standard warranty — typically one year for labor and five to ten years for compressors, depending on the brand and model. We handle all warranty claims directly with the manufacturer on your behalf, including documentation, troubleshooting, and parts procurement. If an issue arises during the warranty period, you call us — not the manufacturer’s 800 number. We also offer extended labor warranties on installations for clients who want additional coverage beyond the manufacturer’s standard warranty period.
