What Drives Costs in Largo?
Prices vary by unit type: tank gas ($750–$1,900), electric ($850–$2,100), tankless ($1,400–$3,300+), and heat pump ($1,700–$3,800). Labor and permit fees add to the total.

Sediment Buildup
Hard water and warm temps accelerate sediment accumulation, reducing efficiency and causing rumbling noises.

Faulty temperature-pressure relief valves can drip or fail, risking water damage; code requires discharge within 6 inches of the floor.
