A need for more space prompted Expert Heating and Cooling to leave its longtime base of operations on West Jefferson in Trenton seven years ago and migrate a few miles west to a new building on Allen Road in Woodhaven.

                The move has worked out well for the company, which has broadened its customer base throughout the southern and western Wayne County areas and even led to the opening of a second location in Canton in 2007.

                But owner Mark Angellotti says the company has not forgotten its roots and still feels a strong bond with the community it had been a part of for nearly three decades.

                “Even though my address says Woodhaven, our roots and our hearts are in Trenton,” said Angellotti, adding that Trenton residents remain a key component of the firm’s customer base.

“Trenton people support us like crazy, and we do our best for them, too. I think a lot of people still consider us a Trenton business.”

                Part of that stems from the fact that Angellotti remains an active volunteer in town, continuing an involvement in the Trenton Rotary Club that stretches back to 1997. He also is active in his own hometown, Riverview, serving as the head coach of the Gabriel Richard High School football team.

                But Angellotti retains a special connection with Trenton, where he first became a business owner in 1997 when he and a partner purchased Expert Heating and Cooling from Bob Maharas, one of the founders.

                “At the end of the day, Trenton residents care about their community,” he said, pointing to examples like strong community turnout for the high school’s Homecoming Game and widespread support of Rotary events such as the PNC Roar on the River. “I’m as proud of being a Trenton Rotarian as I am of Expert Heating.”

                Expert now occupies a 42,000-square-foot building at 21811 Allen Road. Its former 10,000-square-foot home on West Jefferson was purchased by local architect Bob Howey, who basically gutted the one-story building and erected a two-story office building now considered one of the downtown area’s best assets. “It has worked out well for both of us,” Angellotti said.

                The company also acquired a 6,000-square-foot office location at 7320 N. Haggerty Road in Canton a few years ago to help support its growth into Wayne County’s western communities.

                Expert is a full-service heating, ventilation and air conditioning company for both residential and commercial customers. The residential end of the business has surged as of late with customers trying to take advantage of the federal tax incentive that expires Dec. 31. The incentive provides a tax credit of 30 percent on new energy efficient HVAC systems, up to a maximum of $1,500.

                Angellotti called the incentive the “HVAC version of ‘cash for clunkers,’ ” the popular program initiated by the government in 2009 to spur new car sales.

                Expert is a licensed installer for Carrier HVAC systems. Carrier also is helping to spur business by offering a $300 rebate on some of its products. That rebate also is set to expire at the end of the year.

                “We have done a tremendous amount of residential furnaces based on those rebates,” Angellotti said.

                Expert Heating and Cooling was founded in 1975, when Bob Maharas and George Burns purchased what was then called Trenton Heating and Cooling. In 1993 Maharas became the sole owner, and his son, Mike, assisted him running the company until 1997, when the younger Maharas and Angellotti bought the business from Bob. A few years later Angellotti bought out his partner and became the sole owner.

                More information about the history and services of Expert Heating and Cooling can be obtained on its Website, The phone number in Woodhaven is (734) 676-4488.
