"Replacement of Bedroom Radiator valve was made on 1/20/25 by 5 PM. Heat from the radiator only came on the following day 1/21. Bedroom temperature never reached past 69 degrees while all other rooms were at 70 to 72. Also, the bedroom temperature tends to decrease to 66 in 2 to 3 hours from its pick of 69."

"We have been waiting for a call back for over 2 weeks. We had a 4k job to ground our above round pool a month ago. We need the inspection certificate to pass the village inspection. It failed after the first try so the company sent someone else to fix the issue in order to be complaint with our village. We waited from 12p-9p for someone to show up. We received a call late that night that they couldn't come and would come the following day. The electrician finally came 7 days ago. He "fixed the issue". He stated we would receive the inspection shortly. The inspection company just "needed a picture" of the change to approve it. My husband has called Universe several times. Left several messages for the DOO with no response. He just got off the phone with a "Chris S" who says he is a project coordinator. He argued with my husband stating, "we are at the mercy of the inspection company". Universe chose this inspection company! We paid for it! Our village inspector is coming tomorrow (appointment made three weeks ago thinking this would be resolved) and we still have no electrical inspection. My husband had surgery Monday and is supposed to be healing. I NEVER write bad reviews..i try to resolve first but I have nowhere else to go. All I need is the inspection certificate! My next step will be to stop payment. UGH..what is so difficult here?"

"I never leave bad reviews but feel compelled to warn people not to use this man's service. The most unprofessional, short tempered and hostile man. I am a young mother with a 3 month old infant, so getting our hvac fixed is crucial. Vinny canceled on us last minute and rescheduled twice, he bad mouthed other companies who had worked on our system previously, he told us to run our own wires, and then called my father in law stupid for doing it wrong. When I interjected saying that that wasn't very nice and asked my father if we should call someone else, he became irate, yelled at me for saying something, said i ?should mind my business? in my own home, raised his voice loud enough to startle my infant and made him cry, said he ?should have pushed us down the stairs?, and stormed out of the house like a disgruntled prima-donna. The whole situation left me and my baby rattled. This man thinks that the demand for his trade entitles him to speak down to and mistreat customers.Go elsewhere."

FAQs for heating and furnace service projects in Uniondale, NY
Consider replacing your gravity furnace when it's over 30 years old, when you experience frequent system failures, or when your heating bills continue rising despite maintenance. Many older gravity systems operate at substantially lower efficiency rates compared to modern alternatives, often 50% to 60% versus the 80% to 98% efficiency of contemporary furnaces.
Replacement also makes sense when your existing system shows signs of deterioration that could affect safety or when professional inspection reveals significant issues.
Most gravity furnace replacements require between six and 12 hours of professional labor, spanning one to two working days, depending on scheduling and complexity. Basic installations with minimal complications may be completed in a single day, while projects requiring extensive ductwork modifications or asbestos remediation will require additional time.
The timeline includes removal of the old system, preparation of the installation area, placement and connection of the new furnace, and thorough testing.
Watch for warning signs, including inconsistent heating throughout your home, unusual noises during operation, visible corrosion or damage to the heat exchanger, and steadily increasing energy consumption. If your furnace requires frequent repairs or if you notice a yellow or flickering pilot light instead of a steady blue flame, these may indicate serious issues.
Age remains a primary consideration—systems over 30 years old warrant replacement rather than continued repair.
Well-maintained gravity furnaces that pass professional safety inspections can continue operating, but they inherently carry more risk factors than modern systems. Potential concerns include less efficient combustion that may produce carbon monoxide, deteriorating components that could create fire hazards, and the possible presence of asbestos in insulation materials.
Modern furnaces incorporate numerous safety improvements, including automatic shutdown features, sealed combustion chambers, and electronic ignition systems that eliminate standing pilot lights.
