HG Plumbing & Heating Solutions as fully licensed & insured take great pride in our experience, expertise, quality and customer service, that we provide to meet the consumer's needs. It is our mission to provide excellent workmanship, and complete customer satisfaction, from start to completion of a project. In order to understand the needs and expectations of our customers, we take great care to work and communicate, with every customer in a professional manner. Our reputation is based on service, safety and quality, regardless of how large, or small the job. Call us today!

"TLDR: This is a great plumbing company and Harris is my current go-to trustworthy plumber. I highly recommend you give HG a call for an estimate if you need plumbing work. I really loved all the work, and I'm rather difficult to please. My experience (over last few months in 2024): HG Plumbing installed our new hot SS water storage tank, a new toilet for a 1/2 bath, and a LG steam washer and dryer (GAS) in our new laundry room. Harris also added a new dryer exhaust vent to bring us up to code, which was quite tricky due to the how the old (incorrect) vent was run, and he came up with a great customized solution for us, which none of the other three plumbers I met with suggested. 10/10 on ALL the work. Harris and his team was on time, easy to communicate with (text/phone/email--he responds to everything!), PROFESSIONAL, and cleaned up nicely after themselves. Plumbing on the North Shore feels very expensive and HG prices are actually reasonable for the area, especially considering the excellent quality of the services. Invoices are up front and clear and Harris is extremely knowledgable, personable and easy to talk to (answered all my questions and concerns--and had many). We discussed whole house water filtration and few other upgrades done the line, and Harris is an amazing resource on all things plumbing and local/code issues. For those with MCS or healthy home concerns: I have sensitivities to many home improvement odors/chemicals and Harris was very understanding and respectful of this. Even the caulk he used was low VOC and finished off gassing extremely quickly. Normally I take 3-4 estimates before committing for non-emergency/maintenance work, but from now on I'm just calling HG. Done right is everything in plumbing and much more cost effective in the long run."

FAQs for water heater repair or service projects in Cold Spring Harbor, NY

Warning signs include fluctuating water temperatures, a pilot light that repeatedly goes out, unusual noises from the tank, or complete heating failure. You might also detect a rotten egg smell, indicating a potential gas leak, or notice water that never reaches the proper temperature. If your water heater is over eight years old and displaying these symptoms, the gas valve is a likely culprit. Professional inspection is recommended, especially if gas odors are present.

Water heater gas valves are not universally interchangeable. Each valve must match your specific water heater's make, model, and specifications. Important compatibility factors include gas type (natural gas vs. propane), BTU rating, connection types, and physical dimensions. Using an incorrect valve can result in poor performance, premature failure, or dangerous gas leaks. Always consult your water heater's documentation or a professional plumber to identify the appropriate replacement valve for your unit.
