Called these folks for plumbing concerns, and discovered they also provide electrical and HVAC help. Ryan (plumber) come out the day after my phone call, and performed a number of diagnostics. He will be returning with some fixtures we selected during his visit today.
He also provided estimates, at our request, for a new water heater and for a water-conditioning unit. We are more than happy with the service and pricing, and highly recommend these folks, at least insofar as plumbing is concerned although we would expect they're as competent and as honest with regard to the other home services they offer.
