Excellent service, customer friendly, knowledgeable & informative technician. Friendly & courteous scheduling person. I rate Zenner & Ritter, Inc., an exemplary company and would confidently refer them to my family and friends!
Outstanding service. Keith came within two hours of my call. He diagnosed the problem — after another professional HVAC man had been there the day before and the furnace still did not work. New furnace needed installed within two days. Outstanding. Keith was professional, thorough and kind. I 5star this company.
Our repair person was very professional and took the time to let me know what he was doing. He also made a suggestion as to how we may keep our A/C drains clean and save some maintenance cost.
