      Reid was very helpful and professional. He took the time to explain the likely issue with our HVAC system and helped me understand how the system works overall. I really appreciated that he didn’t just look at the problem, but also walked me through what he was seeing and answered my questions. Great service and a very positive experience.

      I had Reid Demosky visit my home for a check up of all my HVAC mechanical systems - including the water softener. Reid was a true professional from start to finish. We started with an overview of my equipment and a discussion around issues I wished to have addressed. Reid's technical knowledge was "best in class" - he went about this annual review methodically and thoroughly. His explanations were easy to understand and informative. I will be very pleased to have Reid return at anytime to service my equipment.

      Today we experienced the first of our annual fall and spring service calls. We are very impressed by Wiehler’s comprehensive service—inspection, repair where necessary, and cleaning of our plumbing, HVAC systems and gas fireplaces. Curtis and Carter were extremely knowledgeable, worked tirelessly, and paid attention to every last detail, including fastidious clean-up before leaving. Curtis also took time to patiently explain our systems, what to watch for going forward, and provided a clear explanation of our billing. Many thanks!
