EXCELLENT Based on 2711 reviews Posted on Google Don PanecTrustindex verifies that the original source of the review is Google. My wife, Susan, and I were extremely satisfied with the professional service, attention to detail and expertise that Gino, the certified service technician from Ray O. Cook Heating and Air displayed on our service call August 4, 2026. Gino was courteous, on time, hard working and took pride in being able to thoroughly inspect and recommend needed repairs to the 4 HVac systems that provide cooling to our home. We were especially surprised to learn that Gino treats each customer’s home as if it were his own home or his mother’s home and provides a high level of service and attention to detail in all that he does. By the end of the day, after Gino had completed servicing on all 4 of our systems, Susan and I had no reservations about signing up to be Ray O Cook Service Club members and have our HVAC and Heating units routinely serviced per their annual contract. We feel very fortunate to have discovered this amazing company.Posted on Google Robert BoehmTrustindex verifies that the original source of the review is Google.
