"One faucet required locating the inside water line leading to the faucet, and then cutting through paneling and sheetrock to remove and replace the faucet. The work was somewhat messy but they cleaned it up well, replaced the insulation & covered the exposed area with a removeable access panel.
The other faucet was easier to replace and included correcting sloppy work that had been done when the previous faucet had been installed.
The two workers were polite , neat and careful not to track water and mud into the house or basement

"Great. The contractor from Jimmy Gusky arrived on time and within 45 minutes had provided a full inspection and determined the unit was fine and had simply malfunctioned temporarily during several extremely hot day.s. So this saved me many thousands of dollars. Great experience."

"During an intense heatwave, Moises provided exceptional emergency service for our aging commercial HVAC units at the church, ensuring they kept running through the hottest days of the summer. Their prompt response, expert repairs, dedication to quality, and fair pricing were truly impressive. For reliable and top-tier HVAC services, Moises is a standout choice. I highly recommend Tyler, Moises, and the entire team at SwiftPro for all your commercial or residential HVAC needs!"

"I recently hired Fred's Plumbing and Heating to replace an electric water heater in my condo, and I cannot recommend Fredy enough. Fredy and his team did a fantastic job replacing my 50-gallon water heater. He gave me a very fair price and installed a top-tier 10-Year Warranty State ProLine® XE model as promised. ​What impressed me most was their attention to details. He was punctual, professional, and handled all the condo logistics perfectly. I will definitely be using Fred's Plumbing for all my future projects. A true professional!"

"I can't say enough about DB's Plumbing. I called in the morning, had a return call within hours and they were at my house that night. 24 hours later, the new hot water heater was installed! Price beat all others. Duncan was professional and knew exactly what he was doing. DB Plumbing is now my GO TO PLUMBER!"

"Albert and Joseph provided truly exceptional service during their visit to my home. Albert first installed my kitchen faucet and food processor, and then, both came back to install a water heater with remarkable professionalism, care, and efficiency. From the moment they arrived, they were responsive, respectful, and incredibly warm. They took the time to explain my options, helped me feel at ease, and ensured I understood why the water heater they recommended was the best choice on the market. On top of that, they went above and beyond by fixing a separate issue in my shower without hesitation. Their dedication, expertise, and kindness made the entire experience outstanding. I am deeply grateful for their work and highly recommend them."

Water Heaters FAQs, answered by experts

You don’t have to replace expansion tanks at the same time as your hot water heater. You may be able to go six to 12 years or more before needing to replace your expansion tank. At $150 to $450, hot water heater expansion tanks are usually much more affordable than the cost of hot water tanks themselves, which average about $1,190.

Unless you have previous plumbing experience or extensive experience with water heaters, you should avoid replacing your electric water heater yourself. This process involves disconnecting wiring and parts from the old water heater and reinstalling them onto the new one, among other difficult tasks. This job is best left to the pros to make sure that everything is connected correctly to avoid serious leaks or malfunctions.

Electric water heaters typically last 10 to 20 years, though proper maintenance can extend their lifespan. If your unit is over a decade old and showing signs of inefficiency—such as higher energy bills, frequent repairs, or leaks—replacement is a smart investment. Tankless models last over 20 years, which can make them a longer-lasting alternative to traditional tank water heaters.

No, boilers and water heaters are not interchangeable because they serve different primary functions. Boilers are used for central heating systems, providing hot water or steam to heat your home. In contrast, a water heater's purpose is to supply hot water for daily household use, such as for faucets and showers. A water heater alone cannot supply the warm water or steam needed for a central heating system.

While they are not interchangeable, it is common to have both a boiler and a water heater. In fact, a conventional boiler often works best when a water heater system is already in place. The two systems can be combined to provide both heating and hot water, either by pairing a boiler with an indirect water heater or by installing a premade combination boiler-water heater unit. For home heating, some homeowners may also opt for a furnace instead of a boiler.

If your water heater is about to celebrate the big 2-0, you may want to consider sending it off to greener pastures. While the water heater may seem to be working well, any conventional, tanked water heater over 10 years of age is at risk of failure. If your water heater is 20 years or older, your best move is to replace your aging heater before it completely breaks down.
