Jake did an excellent job with my furnace check up. He was extremely professional and answered all my questions. He helped me navigate my humidifier settings and my air conditioner cover placement. I definitely recommend Jake and Seimer heating and cooling. They are the best.

Dane was fantastic to work with. He was incredibly patient and took the time to explain exactly what needed to be done in a way that was easy for the average person to understand. His knowledge and experience were evident throughout the entire conversation, which gave me confidence in the recommendations he provided. I also greatly appreciated that he did not try to upsell unnecessary services and instead focused on what was truly needed. Honest, professional, and highly knowledgeable. I would definitely recommend him to others.

Very professional and timely service! The inspection of all five furnaces was thorough and detailed, with clear communication regarding the status of each unit and recommendations for future replacement considerations for furnaces that are over 20 years old. The technician also went above and beyond by providing a battery for a non-functioning thermostat. Excellent service, attention to detail, and customer care. Highly recommended!
