About Cavelli Heating and Cooling, LLC
Cavelli Heating and Cooling, LLC operates as a locally owned HVAC contractor serving Cleveland and surrounding Ohio communities. The business holds a 5-star rating across nine client reviews, with customers consistently highlighting the technician's methodical approach to system diagnostics and installations. Mark handles service calls personally and maintains direct communication with homeowners throughout each project. The company specializes in updating aging heating and cooling systems, including conversions from older oil-based heating to modern high-efficiency gas furnaces and central air conditioning.
The contractor distinguishes itself through individualized attention and technical precision. Mark performs every aspect of the work personally rather than delegating to subcontractors, and he responds to communication promptly according to multiple reviewers. The business installs high-efficiency equipment from major manufacturers and has experience with systems exceeding thirty years in age. Homeowners note that Mark takes time to explain how to balance airflow and educate customers on their new equipment's operation.
Reviewers describe several specific scenarios demonstrating the company's reliability. One homeowner needed a complete heating and cooling transformation, converting from oil heat with no air conditioning to a new furnace and AC unit. Mark planned vent locations meticulously and ensured proper airflow balance throughout the home. Another reviewer called on Mark during summer to install their first-ever central air conditioning system alongside a new gas hot water tank and furnace, all high-efficiency units that continue operating seamlessly. A third customer specifically mentioned Mark saved them money compared to larger companies while delivering the same quality result.
