Founded at the turn of the last century, Stanley Ruth is one of the oldest family-run businesses in the United States. What started as a modest clock-repair shop in Queens in the 1890s, then pivoted to electronics repair and electrical contracting, before becoming an HVAC provider.

In 2018, John Holsapple and his partners, Greg Shapiro and Zach Cooper, acquired Stanley Ruth, continuing the legacy of New York City’s premier heating and air conditioning company for thru-wall PTAC installations, replacements, and repairs.
