Water Heater Problems... In Hudson Massachusetts Installations, Replacements, and Repairs

Same day in almost every case. We’re based in Hudson, so most addresses are minutes away. We keep 30 water heaters in our warehouse — gas, electric, and power-vent — so we usually don’t need to run to a supply house. Call (978) 562-3736. A cold shower in a Hudson colonial in January is not something you wait until tomorrow to fix.

That’s exactly why we built this page. Look at the photos above. If your heater has a metal flue pipe running into a chimney, it’s gas. If it has no flue but a power cord, it’s electric. If it has a black plastic blower motor on top with PVC pipes, it’s power-vent. If none of them match, take a photo with your phone and text it to us. We’ll identify it and tell you what a replacement costs before we even roll the truck.

A standard 40-gallon gas water heater typically runs between $1,500 and $2,200 installed. A 50-gallon power-vent unit runs $1,800 to $2,800. Electric heaters are usually $1,200 to $1,800. The exact cost depends on the unit you choose, whether the venting and gas line are in good shape, and whether the old heater drained clean or left us a mess. We give you a firm quote before we touch anything.

Usually yes. The most common cause is a bad thermocouple — the safety sensor that tells the gas valve the pilot is burning. If the thermocouple is shot, we swap it in about 30 minutes and the heater runs again. If the gas valve itself is failing or the burner assembly is rusted out, replacement makes more sense than repair. We’ll tell you which one applies before we do either.

A power-vent unit uses a blower motor to push exhaust gases through PVC pipe instead of relying on a chimney draft. As the blower ages, the bearings wear and the fan gets louder. A rattle usually means a loose mounting screw or debris in the blower housing. A high-pitched whine is the motor itself going. We can replace the blower motor on most Bradford White and Rheem units. If the tank is old and the motor is shot, full replacement is usually the smarter call.

Most standard gas and electric water heaters last 8 to 12 years. Power-vent units tend toward the shorter end of that range because the blower motor adds a failure point. Hudson’s municipal water is treated with chlorine, which accelerates corrosion inside the tank slightly compared to untreated well water. The single best thing you can do for longevity: drain a few gallons from the tank every six months. It clears the sediment off the bottom before it hardens. Almost nobody does it, but the heaters that get drained last.

No. A leak from the bottom of the tank means the steel shell has rusted through from the inside. There’s no patching it. Shut off the water supply to the heater immediately, turn off the gas or electric, and call us. The tank will continue to leak until it’s replaced, and a small leak can become a flooded basement with little warning.

If your water heater was sized for two people and now there are four, or if it’s eight years old and the bottom is layered with sediment, the recovery time stretches out. Sediment insulates the water from the burner, so the heater runs longer to reheat the same volume. A 40-gallon tank with heavy sediment might only deliver 30 gallons of usable hot water. We can flush the tank and see if it recovers — if the sediment is too dense or the dip tube is broken, replacement is the fix.
