Navien expertise
High-efficiency equipment needs correct setup
Navien condensing boilers and tankless water heaters are sophisticated equipment. Most of the problems we see come from gas supply, venting, condensate drainage, water quality, piping and control setup — not from the unit itself.
Navien is one of our areas of specialized expertise — not the limit of what we service. The same diagnostic approach applies to every boiler and water heater we work on.
