Lochinvar HVAC & Plumbing Services

Lochinvar boilers are known for their high-efficiency modulating condensing designs, particularly in their Knight and Noble series, which deliver strong performance with precise temperature control and solid turndown ratios. These systems are built to handle both space heating and indirect domestic hot water, with stainless steel heat exchangers that hold up well when properly maintained. Compared to other brands in the same category, Lochinvar offers good control logic and serviceability, though like any high-efficiency unit, they require correct installation, proper venting, and clean system water to avoid premature failure. I’ve installed and serviced a range of Lochinvar systems and know where they perform best and where shortcuts cause problems—especially with piping layouts, combustion setup, and system protection. When installed correctly, they’re reliable, efficient boilers that make sense for both retrofit and new construction applications.
