O'Hara Heating and Cooling is Michael O'Hara's Worcester HVAC business; the company says he founded it in 2020 and handles each job himself as owner and lead technician. It does residential and light-commercial installation, repair and maintenance around Worcester, Holden, Shrewsbury and nearby towns, and lists MassSave installer and Mitsubishi installation credentials. His Massachusetts HVAC licence (1010-SM-J1) is active. Its written reviews run from 2023 to 2024, all on HomeAdvisor. In a November 2023 review, one customer said Mike had replaced both AC condensers after they failed, relocated the condenser line for a remodel, replaced the thermostat and put in a new baseboard heating system, all on time and within budget. Another November 2023 customer who had used him for three or four jobs said he knew his sizing and equipment and was competitively priced. An August 2024 customer said he was on time, efficient and on budget. HomeAdvisor shows 4.9 stars from 9 ratings, and BBB gives the company an A-.
