Ver professional and helpful
Anthony Krachenfels from Universe Home Service was very professional and knowledgeable. He was honest about the situation and mentioned that he could have charged for opening up the ceiling to find out the problem, but since it wasnโ€™t a plumbing issue and not his area of specialty, he chose not to charge for that work. I really appreciate and respect his honesty.

He cleaned up really nicely afterwards.

He also recommended a reliable company for the necessary repairs, and they did a great job. If anything else comes up in the future, I will definitely be calling Universe Home Service again.
Great service, great technicians

Signs Your Furnace Needs Repair

When your furnace is not working right, the problem can show up in a number of ways.

Our technicians diagnose the issue accurately and restore dependable heat to your Long Island home.

A furnace that runs but blows cold air, or will not start at all, is one of the most urgent calls we handle across Hicksville, Bethpage, and Levittown. The cause could be an ignition failure, a tripped safety limit, a thermostat problem, or a fuel supply issue, and we pinpoint it and restore heat quickly.

Cold spots in certain rooms while others stay warm often point to airflow restrictions, ductwork issues, or a blower problem. We see this regularly in split-level and ranch homes across Wantagh, Seaford, and Bellmore where original ductwork has not been rebalanced in decades. Evaluating the full system brings consistent warmth back to every room.

A furnace that short-cycles, turning on and off repeatedly without completing a full heating cycle, puts strain on components and drives up energy costs. Homeowners in Merrick, East Meadow, and Massapequa call us for this repair regularly, and identifying the root cause protects the system from further wear.

Banging, rattling, squealing, or grinding sounds from your furnace are never normal. These noises can signal loose components, a failing blower motor, or ignition problems that need professional attention before they worsen, and the calls we handle most often come from older homes in Mineola, Valley Stream, and Rockville Centre where systems are well into their second decade.

If your heating costs have been climbing with no change in usage or fuel prices, your furnace is losing efficiency. We see this regularly across Garden City, Syosset, and Plainview as systems age, and inspection usually turns up worn parts, airflow restrictions, or performance issues forcing the system to work harder than it should.

A furnace that struggles to light, short-cycles after ignition, or shows a yellow flame instead of blue needs immediate attention. We handle these calls regularly in Amityville, Lindenhurst, and Copiague where older gas and oil conversions are common, and combustion problems are both a comfort issue and a safety issue that gets diagnosed and resolved correctly.

Why Long Island Homeowners Trust Universe for Furnace Repair

Choosing who handles your furnace repair in Farmingdale, Huntington, or anywhere across Long Island matters when the temperature is dropping.

A technician who responds quickly, arrives prepared, and tells you the truth about what they find is what separates a real fix from a callback.

Same-day service is available for most furnace repair calls across Nassau and Suffolk County, and for no-heat emergencies in Copiague, West Babylon, Deer Park, and North Babylon, 24/7 service means you are never left waiting through the night.

Our technicians work on gas furnaces and oil systems, which are both common across Long Island, and they arrive knowing the failure patterns specific to this market rather than applying generic textbook answers to regional problems.

You hear your options and the repair cost before any work begins, and because our service vehicles carry common furnace parts, most repairs are completed in a single visit rather than waiting on a parts order.

Universe is a BBB Accredited Business and PHCC member, and every furnace repair is backed by those standards.

Should You Repair or Replace Your Furnace?

When your furnace needs a significant repair, replacement is a fair question to ask.

Both options get an honest read with no pressure in either direction, based on the system in front of us and what the next several heating seasons look like.

Gas furnaces typically last 15 to 20 years, and oil furnaces can run longer with good maintenance. A unit under 12 years old with an isolated component failure is almost always worth repairing, while one past 15 to 20 years facing a major repair, especially if the heat exchanger is involved, is worth a replacement conversation.

A furnace that has needed service more than once in the past year is wearing out across multiple components. When repair costs approach half the cost of a new system, replacement delivers more reliability per dollar than continued investment in aging equipment.

An older furnace losing efficiency runs longer to deliver the same amount of heat, which shows up on your heating bill. On Long Island, where oil and gas costs run higher than the national average, the monthly savings from a newer high-efficiency unit add up faster than in most markets.

A cracked or corroding heat exchanger is a safety issue that ends the conversation. Your technician gives you an honest assessment of what is actually in front of them before any decision is made.

Frequently Asked Questions About Furnace Repair

How often should I schedule furnace maintenance?

Annual maintenance is the standard, and fall is the right time to do it. A pre-season tune-up on your furnace checks the ignition system, inspects the heat exchanger, cleans the burner, tests safety controls, and verifies the system is ready for the heating season. Most furnace failures we handle in January and February would have shown up as a minor issue in October, and Home Comfort Club members have this visit scheduled automatically.

What are the signs my furnace needs repair?

Uneven heating, unusual sounds, short-cycling, a yellow or flickering pilot flame, or a furnace that will not start are all signals something needs attention. Rising energy bills with no change in usage are also worth investigating, and on Long Island where winters regularly hit the mid-20s, scheduling service before a problem gets worse often prevents a no-heat emergency on the coldest night of the season.

How long does a furnace repair take?

Most furnace repair calls are completed in a single visit. Our service vehicles carry common parts for gas and oil systems, so the majority of repairs do not require a return trip. The total time depends on the nature of the failure and the parts involved, and your technician gives you a realistic estimate before starting.

Do you service both gas and oil furnaces?

Yes. Our technicians work on both gas and oil furnace systems across Long Island. Oil systems, which remain common in many Nassau and Suffolk County neighborhoods, require specific expertise in burner service, nozzle replacement, and oil pump maintenance, and we handle both equipment types with the same single-visit service.

Is it better to repair or replace my furnace?

That depends on the age of the system, the cost and nature of the repair, and how often it has been needing service. A furnace under 12 years old with an isolated failure is almost always worth repairing, while one past 15 to 20 years with recurring issues or a major component failure is worth a replacement conversation. You hear an honest assessment based on what the technician actually finds.
