WM. E.Donnelly Heating & Cooling has served Cleveland and surrounding Cuyahoga County since 1992, earning a 4.8-star average from 16 customer reviews. The family-owned contractor employs certified technicians and holds an Ohio contractor license. Service areas include Cleveland proper, Lakewood, Parma, and nearby suburbs. Homeowners seeking furnace or central air service can reach the office at (216) 521-7000.
Annual preventive maintenance visits form a key part of how Donnelly builds long-term customer relationships. Technician Dave, mentioned by name across multiple reviews, conducts furnace and central air inspections and advises homeowners on equipment lifecycle decisions. The company also handles full equipment replacements, with one customer noting confidence after a new furnace and cooling system installation two years prior.
A negative review from a customer familiar with HVAC work provides a candid look at how diagnostic visits work. Technician Dave spent an hour examining a furnace with an ignition issue, explained the faulty ignition control valve and pilot with spark rod, and quoted $600 or more for parts. He then recommended a supervisor visit to estimate a full replacement. The customer chose to purchase a new ignition control for $115 and a pilot assembly for $45 at a local supply house and completed the repair independently. Positive reviewers, however, credit Dave with thorough annual inspections and clear guidance on whether to repair or replace aging equipment.
What Customers Say
One of 3 reviews cites a $186 diagnostic fee and $600-plus repair quote as excessive, while 2 reviews praise technician Dave by name for reliable annual inspections and clear communication about equipment condition. The contrast reflects a common divide: customers facing big repair bills sometimes feel pushed toward replacement, while customers in routine maintenance relationships value the consistency and preventive approach.
