"We were very pleased with the work that the Genove technicians did. They removed our 40-year-old gas boiler and associated water heater and replaced it with a new system. They tested the new system carefully, put explanatory tags on all of the relevant pipes and faucets, and cleaned up well. The team members were polite and worked hard. We had similarly good experiences when Genove technicians came to repair our central AC system. They were knowledgeable and efficient, got the system going again, and the price was fair. We continue to use this company for heating and AC repairs."

"I called the company on Sunday evening and they responded promptly early in the morning. My system was installed by them 3 years ago but somehow I missed last year's annual servicing. With the current heat wave it was severely underperforming. They sent out Robert Duclos within the hour. He diagnosed the problem---not enough Freon in the system, grass and mulch build-up in the compressor, valves buried under the landscaping--and fixed it all for the price of the annual service contract. I would definitely recommend them for anyone needing central a/c work."

"Hello, Yellow Dog Home Services was phenomenal! Jeffrey was able to come the same day, complete an assessment, and define the next steps for the installation of a new hot water heater the following day. He is very personable, professional, knowledgeable and affordable. Yellow Dog is now saved in my iPhone for future project needs! Richard"

"Replaced my water heater in an emergency and went tankless. Super happy with the entire team. They provided me temporary hot water and came back the next day to put on the tankless water heater. They gave me options and I’m happy with going tankless"

Water Heaters questions, answered by experts

If you want instant hot water and to reduce water waste while improving convenience, a hot water recirculating system is worth it, especially if you find your hot water heater is not hot enough. These systems can save thousands of gallons of water each year so you don't have to wait for hot water at faucets and showers. The upfront investment can be high, especially for systems requiring additional plumbing, but the long-term savings on water bills and added comfort make them a worthwhile upgrade.

Tankless water heaters heat water as it passes through the unit instead of storing heated water in the tank. Their ability to produce hot water on an as-needed basis makes them more efficient. However, they are generally more expensive than traditional units. Is a tankless water heater worth it? Most homeowners will save money with a tankless unit in the long run by using less energy.

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.

The average cost to replace a water heater is around $1,325, with a typical range of $900 to $1,800 for a standard replacement. The final price depends on the type of heater (tank vs. tankless), its size, fuel source (gas or electric), and the complexity of the installation. A simple one-to-one replacement will be on the lower end of the cost spectrum. However, if you are switching from one type of heater or energy source to another, you can expect labor costs to be significantly higher due to the extra work involved. It's also worth considering that while gas and electric heaters may have similar upfront costs, their long-term operating costs can differ based on local utility prices.

Basements, specifically those without any air conditioning, are the best location for a hybrid water heater. These rooms are less likely to experience extreme temperature fluctuations, which can affect your hybrid water heater’s efficiency and performance. Basements often have more than enough space for their tanks and proper air circulation. Hybrid water heaters can also be a bit noisy, but putting them in your basement will keep the noise away from your main living areas.
