Tankless doesn’t win every category. The right choice depends on your home, your budget, and how your household uses hot water.
A tank usually costs less up front, supplies the hot water stored in the tank, and is usually a straightforward swap. A tankless unit costs more up front, can provide continuous hot water when sized correctly, and is compact and wall-mounted, but may need gas, venting, or drain changes.
Switching from a tank to tankless is often possible. We check your gas or electrical capacity, the venting route, a place for condensate to drain, and how much hot water you use at once.

We’ll tell you plainly which makes sense.
A whole-house heating system often lasts around 10 to 14 years. Before that, a repair is usually the smart call. After that, it depends on what failed and how often it’s been happening.
Plenty of boilers can be repaired — many just need a part, a cleaning, or a system that’s set up properly. A modest repair on a sound boiler is usually worth it. Once a boiler is past about 15 years old, it’s worth pricing a replacement too.

If it’s below freezing and the house is cooling fast, call us at 1-800-754-0180 instead of using the form — pipes can freeze. Same-day service is available; call to check today’s schedule. We’re open Monday–Saturday, 8:00 AM–5:00 PM.
Smell gas? Don’t flip switches. Get everyone outside and call your gas utility or 911 from outside.
If you have a moment, check that the thermostat is set to Heat, the service switch and breaker are on, and (on a furnace or heat pump) the filter isn’t clogged. On a boiler, note the pressure if it’s well below where it normally sits.
More checks are on our no heat page.
