Frequently Asked Questions

Are heat pump water heaters worth it in Florida?
Florida's warm year-round temperatures let a heat pump water heater pull heat from ambient air efficiently in every season. Compare current equipment and installation quotes on their own merits; the former residential federal credit is unavailable for property placed in service after December 31, 2025.
Do tankless water heaters have problems with Florida hard water?
Yes — Florida's hard water causes limescale buildup in the heat exchanger of tankless units, reducing efficiency and eventually causing failure. Annual descaling with white vinegar is recommended. A whole-home water softener upstream significantly extends tankless heater life.
