DiMarco & Associates LLC

At DiMarco & Associates, LLC, we combine the resources, technology, and training associated with a large HVAC provider with the personal attention and responsiveness of a local contractor. Based in Chagrin Falls, we serve homes and businesses throughout Northeastern Ohio, including Twinsburg, Mayfield Heights, Cleveland, Aurora, Beachwood, Solon, Shaker Heights, Lyndhurst, Kirtland, Willoughby, Chesterland, and Chardon. Our performance-driven approach goes beyond installing or repairing equipment: we measure, test, and verify that each system operates efficiently, safely, and as designed.

As Carrier Comfort Specialists, we design, install, and service HVAC systems using advanced diagnostics, industry best practices, and manufacturer-approved standards. Our capabilities include airflow and static-pressure testing, system commissioning, combustion analysis, and indoor air quality evaluations. By studying the data behind a system’s performance, we can identify problems that might otherwise affect comfort, air quality, energy efficiency, or equipment operation. We also provide eco-friendly system design, water heater replacement, advanced filtration, and ventilation solutions. Our heating services cover furnaces, heat pumps, boilers, and geothermal systems, and we service all makes and models of heating equipment. Annual and multi-year preventive maintenance agreements are available, with temporary portable heating systems provided to members during equipment outages.

For commercial customers, we handle installations, repairs, ductwork, computer cooling rooms, and HVAC needs in both new and older buildings. We test, adjust, and balance systems to measure airflow, uncover existing issues, and help equipment run at optimal levels. We can also conduct full data-center evaluations to assess cooling efficiency throughout the year. Whether we are working in a home, commercial property, or specialized technical environment, our focus remains the same: hands-on service supported by careful testing, technical expertise, and solutions built around HVAC performance.
