"They were very fast to respond to my call and were able to send someone within two hours. The replacement of the hot water heater went well. For the water pipes they use copper crimp fittings instead of soldering so it will be interesting to see how that holds up over the years. My only concern is how they ran the gas line. They use Gastite CSST which is fine, but the CSST is run so it goes downward then back up and then downward again before it enters black pipe that has a moisture trap. It seems to me that if there is any moisture it will end up in the CSST instead of the trap. In addition, there is a pretty good bend in the CSST right before it goes into the trap section. Also, Teflon tape was used on the all the joints instead of joint compound. I think I will get someone from a different company to come in and take a look at it."

"My grandson flushed his little yellow bus down the toilet Friday afternoon. I called several plumbers in the area. By late Saturday afternoon I had only 1 returned call saying they could come out Monday morning. A friend suggested I call Gentille Plumbing and Heating. I called them and they said they could come early Sunday morning. Ryan arrived promptly as promise and quickly determine how to approach the issue and retrieved the little yellow bus. Cleanup was quick and pricing fair. Ryan was professional , friendly and was on his way within 45 minutes of arrival. Thank You Gentille Plumbing and Heating"

"I recently had a brand new HVAC system installed for both heating and cooling, and I couldn’t be happier with the experience. The team at Comfort Professor was extremely professional from start to finish. They worked efficiently, paid attention to every detail, and left everything spotless when the job was done. The cleanup was perfect, which I really appreciated. Highly recommend them if you’re looking for quality work and a smooth, hassle-free installation!"

"We contacted Pro Comfort Control to bid on the installation of a ductless mini-split in our sunroom. With many companies the person who shows up is essentially a salesperson and isn't as knowledgeable about the systems and the intricates of installing them...not so with Ryan. He was able to answer every question and explain why he was answering in a specific way related to the individual peculiarities of our house. The quote was very competitive and they use great equipment and materials. The Office Manager Alex was easy to work with in regards to scheduling and any additional questions. Installation was great and as an added bonus they smelled gas in the crawlspace while installing the lines and quickly replaced a corroded propane line for our hot water heater. You will not find a better partner for all your home cooling and heating needs."

"I couldn't recommend these guys more. We had a 21-year old boiler replaced and upgraded, and a new hot water tank installed. I can't think of a single way they could have improved the whole process. From start to finish, they were knowledgeable, on time, clean, considerate, extremely professional and they did exactly what they said they would. The also installed a temporary hot water tank and left electric space heaters on the one night the burner was out of service. Everything is now working as they said it would, and a big bonus is their workmanship actually LOOKS great too! A+++"

Water Heaters FAQs, answered by experts

The average cost to install a new water heater is approximately $1,300, with a typical price range between $880 and $1,800. The final cost depends on several factors, including the type and size of the unit, its location and accessibility, and the amount of labor required. For example, installing a unit in a tight space like a crawl space can increase labor costs. The type of water heater significantly impacts the price: while a conventional gas heater might cost less than $1,000, tankless models can cost around $2,600 to install (and up to $3,500), and solar heaters can cost upwards of $3,700. Other factors that can affect the total price include the fuel type, vent system requirements, permits, and whether any additional plumbing work or repairs from previous water heater damage are needed.

Price variations arise from size, type (tankless or tank), efficiency grades, and installation complexity, including labor and materials.

When installing a new furnace, it's a good time to consider other projects that can enhance your home's energy efficiency. A great first step is to get a home energy audit, which will identify areas for improvement. Common recommendations include sealing or replacing windows and adding insulation to the attic. These upgrades can help you save money on monthly utility costs. You might also consider installing a smart thermostat to make heating your home more convenient and efficient.

If your gas water heater is over 20 years old, it should be replaced. Gas water heaters can last up to 12 years and while they can exceed this expectancy if well-maintained, a heater that's 20 years old would require replacement. The heater is unlikely to run as efficiently as a new model and could be more expensive to do so.

No, you’ll need to drain the tank before changing a water heater element, as the water heater element sticks through the side of the tank and uses a gasket to prevent water from pouring out. However, you don’t always need to drain it completely. If you’re only replacing the upper heating element, you can drain the tank until the water line is below the element. If you’re replacing the lower element, you’ll need to drain the whole thing.
