ICM Controls Reports Record Sales Growth During FY2021

ICM Controls Reports Record Sales Growth, Improved Delivery Metrics, and Capital Improvements During FY2021


ICM Controls President & Chief Executive Officer Joseph Bonacci recently disclosed positive fiscal year 2021 performance results for the Syracuse, New York-based electronic controls designer and manufacturer. Highlights include a 30% growth in ICM’s annual sales and increased on-time delivery by 20%. Bonacci also noted the company’s substantial investment in millions of dollars of capital equipment, including automation machinery, and the addition of two new facilities—a 14,000 ft2 manufacturing facility and a 4,000 ft2 warehouse facility—all part of ICM’s continued commitment to vertical integration, speed to market, and providing high-quality, American-made products.

As a provider of parts for equipment used on the front lines to stop the spread of coronavirus, ICM Controls was granted an exemption from New York State’s 100% workforce reduction mandate and was able to remain operational throughout the pandemic. A change in last year’s sales strategy also bolstered growth as ICM expanded beyond its leading position in the HVAC industry and began aggressively targeting five new vertical markets: Appliance, RV, Marine, Pool & Spa, and Electrical.

In a year when businesses across multiple sectors are reporting decreased sales and reduced profits due to COVID, Bonacci credits the company’s performance to ICM’s ability to pivot on the fly. “2021 wasn’t a normal year for anyone in business. ICM is certainly no exception,” shared Bonacci. “However, a lot of businesses would be thrilled just to break even, but ICM was able to grow our market share and expand our market presence in a way that allows us to maintain the quality and value of our product portfolio and the satisfaction of our customers as priorities. I’m incredibly proud of every member of the ICM team. This kind of success would be commendable any year, but during a global pandemic, it’s really exceptional.”

ICM Vice President Zachary Kadah echoed this, saying, “ICM is known as an American manufacturer that delivers speed to market without jeopardizing quality. The ICM Team showed up every day through a pandemic to demonstrate our abilities last year and continues to do so now. We are proud to prove there is success making it in America.”

ICM designs and manufactures all of its products at its state-of-the-art manufacturing plant in Central New York, where it essentially combines three factories under one roof – captive printed circuit board fabrication, fully-automated electronic assembly, and captive injection molding, making ICM Controls one of the most vertically integrated facilities in the country. In light of pandemic-related shipping delays and import restrictions, ICM’s vertical integration and US-based manufacturing were competitive advantages.

ICM Controls Expands Into 5 New Vertical Markets


ICM Controls, a leading ISO Certified U.S.-based manufacturer of electronic controls, announced a major shift in its sales strategy to expand beyond its leading position in the HVAC industry and begin aggressively targeting five new vertical markets: Appliance, RV, Marine, Pool & Spa, and Electrical.

In support of its new growth initiative, the company also announced the addition of Roy Cramer, Thomas Victorin, and Michael St. Joseph to its sales team, as well as the promotion of Anish Donald to Global Project Manager. Cramer will serve as the National OEM Sales Manager for the HVAC and Appliance industries, and Victorin will serve as the National Sales Manager for both the OEM and Aftermarket for the RV, Marine and Pool & Spa industries. St. Joseph is the company’s new Eastern Regional Sales Manager in support of all divisions. They join a seasoned sales team that includes Mike Tracy, National Sales Manager for the HVAC and Appliance aftermarket, and Everett Mastrich, Western Regional Manager. Tracy is also the company’s acting Central Regional Manager.

“ICM is long-known for the quality of its product and the knowledge of its expert employees,” said ICM Controls President Joe Bonacci. “This expanded team ensures we have the leadership and sector knowledge to hit the ground running in these new markets as well.”

Roy Cramer joins ICM Controls from Probes Unlimited, where he spent more than a decade as their lead Sales Engineer calling on OEM accounts in the HVAC and Appliance industries. Thomas Victorin comes from Dometic Group, where he held the position as Chief Electrical Engineer for the past 6+ years. Michael St. Joseph previously worked for Carel USA for nearly 10 years, serving as Managing Director during his last five years with the company. Anish Donald has been with ICM Controls for almost three years as a Systems Engineer before his promotion to Global Project Manager.

“We already manufacture controls for several prominent OEM customers in each of these markets,” said Zach Kadah, Vice President for ICM Controls. “Additionally, a lot of our branded aftermarket controls that we sell to the HVAC industry cross over to these other markets already. With a concerted effort from our Sales & Marketing teams, our goal is to quickly capture market share and become a major presence across all industries.”

ICM Controls Launches 3 New Replacement Furnace Control Boards

ICM Controls, a leading ISO-certified, American-made manufacturer of electronic controls, announces the launch of three new replacement furnace control boards. The ICM2811ICM2812, and ICM2813 control boards are ETL-listed and affordable, high-quality OEM replacements for popular Goodman Mfg., White-Rodgers, and Lennox models.

The ICM2811 is a form, fit, and functional replacement for the Goodman PCBBF110/S, PCBBF123/S, 0130F00005/S, PCBBF112/S, B18099-26/S and compatible boards. The ICM2812 is a low-cost, board-only replacement for the White-Rodgers 50M56U-843 universal replacement board. Installers who prefer to order the control board complete with an assortment of cable harnesses can also order the ICM2812-KIT, making it a replacement for more than 150 additional OEM boards.

“In marketing the ICM2812, we wanted to give the contractor the flexibility to buy and stock up on just the replacement board or the entire kit,” said Kevin Jobsky, Senior Marketing Manager for ICM Controls. “White-Rodgers has done a sound job in building up an install base for its universal board, but contractors shouldn’t be forced to spend a lot of extra money on extraneous parts packaged into the OEM kit that is just going to end up in a landfill. ICM2812 allows contractors to buy exactly what they need.”

The ICM2813 is a form, fit, and functional replacement to the Lennox SureLight™ board, including part numbers 10M9301, 12L6901, 56L8401, 68M0801, 83M00, and compatible models.

“With the ICM2811, ICM2812, and ICM2813, ICM has three winners that should be very popular with wholesalers and contractors across the country,” said Jobsky.

ICM Controls has been manufacturing quality replacement controls for more than 36 years. Its vertically integrated manufacturing facility located in Central New York features a state-of-the-art printed circuit board shop, auto- and hand-assembly areas, plastic injection molding operations, design, and engineering services, as well as a renowned tech service department and call center for field support.
