Water Heater Service FAQ
My water heater isn't producing hot water, what should I check?
For electric units, check the circuit breaker. For gas units, check the pilot light and make sure the gas valve is open. If neither resolves it, call us. Most no-hot-water calls are diagnosable and repairable on the first visit.
Is it worth repairing my water heater or should I replace it?
It depends on the failed part, tank condition, repair cost, warranty coverage, water quality, and service history. A sound tank with a replaceable component may be worth repairing. A tank leaking through its body needs replacement. We inspect the equipment and explain both options when either is reasonable.
Do you offer same-day water heater replacement?
Same-day tank replacement may be available when the required unit is in stock and scheduling allows. We stock Bradford White tank units. Call us at 603-623-0412.
How often should a tankless water heater be descaled?
Annually in most Southern NH homes. Hard water accelerates scale buildup and can significantly reduce efficiency and heat exchanger life if left untreated.
