We are impressed with the longevity of many of the solar thermal systems we see on today’s homes. When repairs are needed, they often are just in need of a replacement expansion tank or circulator pump. Generally, we can do a system evaluation in under an hour, identify what failed component(s) need to be replaced and often complete the repair on the same site visit. On occasion, a system may need a more specialized part, at which point we can usually source the part and get it installed within the same week. Our labor rate is $110/hour and we charge an additional $90/hr for one direction of travel.
