"Was able to come the same day. He picked up and installed a new gas hot water heater and the Installation costs were very reasonable. Would highly recommend. He even called after the installation to make sure I was getting hot water and there were no leaks."

"Woke up one morning and noticed that one of the zones of my furnace was off so I called several contractors, Hudson valley HVAC was the second I was in contact with. Mitch walked me through what we thought was the problem and was kind enough to offer to help me fix it myself in an effort for me to save some money. As it turned out it was beyond my abilities and in fact it ended up that four pipes burst. Mitch had one of his guys come over to get started on the work arrived at 11:30 a.m. Monday didn't leave till after midnight Tuesday morning and the job was done with great care to detail. I can't speak highly enough about Mitch and Nick at Hudson Valley HVAC. Not only was the price competitive the first thing they did was offer us heaters when they arrived because the house had gotten so cool. They were professional and personable and I would highly recommend them to anyone who needs HVAC services."

"Moved heavy boiler up difficult site. Installed in one day. Very professional and patient in detailed explanations of complex zoning issues. Prices are high in Dutchess Co. compared to other areas of NY. I generally think plumbers are a safer bet for a maintenance plan and longer lasting businesses than most HVAC companies."

"Nate called me quickly after my request had been submitted for a replacement 40-gallon natural gas hot water heater. Nate made an excellent first impression; as I spoke to him on the phone, I knew he knew what he was talking about. The heater was installed that day with meticulous attention to detail, and the price was below the initial quote."

"We have used Joe for multiple projects over the past 10 years and he never disappoints. He is courteous, prompt, and knowledgeable. We recently had our hot water heater breakdown and Joe came right away and replaced it. There were some problems with the unit and he kept coming back until everything is now perfect. He is extremely patient and never loses his cool. It is so refreshing to deal with someone who is dependable and easy to work with."

"Two guys took their time explaining everything repaired and replace my piping and spigot since I had a leak also tested my water to see if it safe to drink. I live in Woodbury NY and the water is not safe to drink by the way. Great professional guys and did the job quick. Going to set another appointment to put a filter in the kitchen for cooking and for the fridge line to be used for drinking water and ice."

"I had an excellent experience with Aquarius Master Plumbing and Heating. On a Sunday, I submitted a request through the Angie app for a leaking toilet seal that was allowing water to drip into my basement. They responded almost immediately and scheduled a technician for 8:00 AM the very next morning. Jason arrived on time, quickly diagnosed the problem, and completed the repair efficiently. It was obvious he was highly experienced—everything he did was second nature to him. He worked neatly, kept the work area clean, and took pride in his workmanship. On top of that, he was courteous, professional, and a true gentleman. From the prompt response to the quality of the repair, the entire experience exceeded my expectations. I would not hesitate to use Aquarius Master Plumbing and Heating again and highly recommend them."

"I had a plumbing leak since February 2024 whereas the leak was coming from my bathroom shower leaking into my kitchen, when I immediately contacted my home warranty American Shield, they never provided me with a Plumbing contractor. From February 22, 2024 until March 24, 2024, I continued to have leakage. American Home Shield then told me they had no contractors to assist me with my plumbing issues and therefore wanted me to identify a Plumbing contractor and then submit the diagnosis to them for review and approval. I then identified Royal Class Service and they diagnosed the leakage as a Shower Valve Replacement whereas they would need to open drywall from the closet to gain access for repair. The estimate from Royal Class was over $2,000.00. American Home Sheild then sent PROSERVICE HVAC & PLUMBING for a second option located in Connecticut. They stated that Royal Class inflated the cost repair and this Pro-Service Company was supposed now take over the repairs. I waited three more weeks because when I called Pro-Service requesting a date for repair they continuously told me they are waiting for valve they ordered from Home Depot. They are the worse!!! I'm Disabled and was out of my shower usage for three months. Well on a Thursday of early May, I happen to see Neighborhood Plumbing truck and contacted Anthony (contractor). Anthony came to home so professional and concerned to assist me with the well overdue plumbing issue and Neighborhood Plumbing repaired this in less than two hours at a price that was extremely fair and far more less than Royal Class quoted and five star professional than American Home Sheild and Pro-Service located in Connecticut. Please don't get taken by these companies. Anthony could have attempted to inflate his prices and robbed me like Royal Class attempted or he could have never come back to repair just as Pro-Service did. But, Neighborhood Plumbing does not have professional integrity they get the job done at a cost that's not ROBBERY! I had a horrible experience with these former companies and I urge you to seek out Neighborhood Plumbing if you need Plumbing, Heating & Cooling Services. Thank you Neighborhood Plumbing,"

Water Heaters questions, answered by experts

A single shower consumes an average of over 17 gallons, while brushing your teeth with the water running uses up to four unnecessary gallons. Watering the lawn spreads hundreds of gallons of water across the yard each time. Limiting water usage in these areas can significantly cut down your water bill.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

Homeowners insurance may cover the repair or replacement of a water heater if it's damaged by a covered peril, such as a fire or a burst pipe. However, policies typically do not cover repairs or replacement needed due to normal wear and tear, old age, or lack of maintenance. For these issues, a home warranty or a manufacturer's warranty may provide coverage. While the policy might not pay to fix or replace the malfunctioning appliance itself, it often covers the cost of water damage restoration caused by the faulty water heater. Always check with your insurance provider to understand the specifics of your policy.

Depending on the brand of water heater, you may need to install an expansion tank in order to meet the conditions for warranty coverage. It’s important for consumers to read the fine print of the warranty to see if an expansion tank is necessary. Even if an expansion tank isn’t required for the warranty, it’s usually mandated by building codes—although not for tankless water heaters.

While a water heater explosion is rare, it is a serious danger. Be aware of these critical warning signs:

  • Sulfur or Rotten Egg Smell: This is a major red flag, especially for gas water heaters. It can indicate a gas leak, which could ignite and cause an explosion.

  • Leaking Pressure Valve: If the temperature and pressure (T&P) relief valve is leaking, it may not be able to properly regulate internal pressure, creating a risk of bursting.

  • Shaking or Rumbling: Loud rumbling or shaking from the tank can be a sign of extreme pressure buildup.

  • Excessive Heat: If the exterior of the water heater feels unusually hot to the touch, the unit may be overheating dangerously.

  • Rust-Colored Water: This can be a symptom of severe internal corrosion that compromises the tank's integrity.

If you notice any of these signs, especially a gas smell, you must act immediately. Shut off the gas supply to the water heater and call a professional plumber right away to prevent a potential disaster.
