What We Check Before Recommending Equipment
Navien units are commonly considered for high-demand homes and efficient hot water upgrades.
Correct sizing, venting, gas supply, and condensate routing matter as much as the unit itself.
Maintenance planning helps protect performance in hard-water areas.
