Who has had recent favorable experience with hydronic heating service, please? I'd just as soon deal locally. Boiler's fine and fairly new; no need to replace it. Rather, want someone completely familiar with the slab piping and valve systems on Eicher houses. Problem: with all valves open, some rooms warm up just fine; others stay stone cold. I'd appreciate your recommendations.
Please direct recommended companies to poster via a PM.
Thank you.
