“Needed emergency intervention for heating issue, One Hour AC and Heating answered the call. Josh was the service tech who responded to my home and was very knowledgeable and helpful. He diagnosed my issues quickly and helped me understand my options. I joined the company’s membership program for yearly service and savings because of their professionalism and timeliness. Needed to add here - the installation team finished the complete removal and replacement of my basement furnace in less than 8 hours. Chris, my installation tech was very polite and professional; I truly appreciate his skills and expertise being put to use in my home. Thanks to the entire group!”
