After losing hot water and downstairs heat on a Sunday evening, I called Bill Lohsen mid-Monday morning. I reached the answering service, but Larry returned my call and within an hour Caleb and an assistant were in our basement assessing the issue. I appreciated Caleb's customer-centric approach as he patiently explained the problems, pointed out the issues, identified next steps, and postulated potential pitfalls down the road. For the next couple of hours he and his assistant worked efficiently to fix my system, replacing a faulty main circulator, mixing valve, expansion tank, and feed & back flow combo in the process. Midway through the work, Larry arrived to help them. He showed me the flaky residue (see photo) from the rubber piping that circulates the radiant heat and indicated he'd be back in touch to schedule another visit to flush the system. Aside from not hearing from him yet (it's been almost 3 weeks) and the size of the bill (over $1,200, which seemed to make sense to me itemized--it's just a bitter pill to swallow), service was excellent--customer care, attitude, alacrity, expertise, approach--all top notch. If I have a future issue, I will call them again. read more
