Water Heater Services We Provide
Tank or Tankless?
A conventional tank heater costs less upfront and is a reliable workhorse for most families. A tankless unit costs more to install but delivers endless hot water, lasts up to twice as long, and trims your gas bill. The right answer depends on your household size, usage patterns, and gas line capacity — we'll give you a straight comparison with real numbers for your home.
Warning Signs to Watch For
Water heaters rarely die without notice. Rust-tinged hot water, rumbling or popping sounds, moisture around the base, and dwindling hot-water supply all signal trouble. Most tanks last 8–12 years — if yours is in that range and acting up, have it looked at before it fails and floods the basement. Ask about $50 off a new water heater.
Frequently Asked Questions
How long does a water heater replacement take?
A straightforward tank swap typically takes 2–3 hours. Tankless conversions take longer due to venting and gas line work — usually completed within a day.
What size water heater does my family need?
A family of four typically does well with a 40–50 gallon tank or an appropriately sized tankless unit. We factor in bathrooms, appliances, and peak usage before recommending a size.
Is a leaking water heater an emergency?
A leak from the tank itself means replacement — and it can fail quickly. Shut off the water supply and call us; we offer same-day and 24/7 emergency response.
