Jones Services is now a NO CONTACT service company. Our plumbers, electricians and HVAC technicians are running NO CONTACT service calls. We literally stand in different rooms than our customers, emailing or reading out loud our findings. No handshakes, no paperwork, not even allowing customers to touch iPads. Our technicians wear disinfected gloves, use disinfected tools and whip down anything their gloves and tools touch after servicing equipment. We practice NO CONTACT at work now too. Technicians are not allowed in the office, equipment and parts are delivered to their trucks in the parking lot. Only one employee per vehicle. All company meetings are conducted via Zoom. Most office personal are working from home. Those in the office work apart from each other. No one wants to be quarantined with their toilets backing up, without water or electricity or heat or hot water and now without air conditioning or air filtration or air purification. We are doing everything we can to help all our employees stay health to protect ourselves and our customers.

"HVAC service was amazing from Jones Service. From start to finish everything was perfect. The price was very competitive. Love their work."

Call 845-527-0077 Why pay more to the big guys? Established in 2010 and locally owned, Neighborhood Plumbing, Heating & Cooling offers residential plumbing, heating, air conditioning and drain cleaning services in New Windsor, NY, Newburgh, NY, Cornwall, NY and surrounding areas. Master plumbers license #108. Quality work at fair prices!

"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,"

"Nobody wants plumbing issues, but when they arise, I ALWAYS know that I’m in great hands with Chris and his crew…from their office manager, Diane to all the guys working for them. Each one I’ve encountered has always been very personable and professional. Whatever the issue may be, they educate/explain what‘s going on and what needs to be done to remedy the situation. They’ve installed a water, repaired a furnace leak, installed an in-sink garbage disposal, replaced old knob shut-off valves for the “Lever“ type and FOUND my street-side water shut off valve that was buried below the driveway asphalt during the residence of the previous home owners and most recently disconnected the utilities from an in-ground pool equipment and drained the pool. I’ve used them so many times, I’ve begun to call Diane “Cuz!” lol! :-D HIGHLY RECOMMENDED!"

Water Heaters questions, answered by experts

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.

The standard copper wire gauge to use with any 30-amp circuit is a 10-gauge wire. The National Electric Code specifies a 10-gauge wire with appliances like water heaters running on 30 amps. If you try to use a smaller gauge wire, such as a 12 gauge, with a 30-amp breaker, you run the risk of the wire overheating and melting or causing a fire. Because of the safety hazards, the gauge of the wire is not an area to try to cut costs when connecting a 30-amp breaker to a water heater.

Venting a gas water heater out of the roof is preferable in most cases. Heated exhaust gases naturally rise, so a vertical vent pipe is efficient. If you’re trying to vent through a pipe exiting a wall, the angle of the pipe may be more horizontal than vertical, making the venting system less effective. If you go through a wall, you may need to add a fan to ensure a successful expulsion of the gases outdoors.

Water heater replacement costs around $1,300, but a total install will depend on a few factors. Solar heaters can cost upward of $3,700, while conventional gas heaters may cost less than $1,000. Tankless water heaters, common in apartments and homes without much space, cost around $2,600 to install. Expect the cost to increase significantly if new plumbing is required, or if there is damage from a previous water heater malfunctioning. 

The average cost to replace a water heater is $1,325. How much your replacement heater costs depends on the type, size, and complexity of installation. Gas and electric heaters may cost a similar amount out of pocket, but one type may cost more to operate than the other, depending on the cost of utilities in your area.
