Best Heating & Air Conditioning / HVAC In Long Island City

“I am extremely satisfied with my recent experience with Sideris Plumbing & Heating. John Jr. was professional, patient, and highly knowledgeable throughout the entire process. What initially began as an assessment of my unusually high-water bill and a concerning gas smell quickly turned into a thorough and insightful evaluation of my entire plumbing and boiler system.
Living in a multifamily home, I find the boiler system to be complex, so I especially appreciated his keen attention to detail. He identified that my boiler for the second floor was incorrectly routed to the first-floor gas water heater, an issue I likely would not have discovered on my own. John Jr. took the time to clearly and thoroughly explain everything and ensuring I fully understood. He was able to successfully fixed the issue right away, including identifying a small gas leak. Additionally, he provided helpful recommendations for addressing my high-water bill, even though no active water leak was found.
I highly recommend Sideris Plumbing & Heating and truly appreciate the outstanding service provided.“
