Our Furnace Replacement Process

Replacing your furnace is a big step, but it does not have to feel overwhelming. Universe guides you through every stage so you know exactly what is happening and what comes next.

You get a technician who evaluates your home before recommending anything. They look at your current system, your ductwork, your fuel source, and your home’s actual heating load. Nassau County homes built in the 1950s and 1960s often have layouts and ductwork that require careful assessment before a replacement can be correctly sized. You receive upfront pricing before any work is committed, so you know what system is going in, what it costs, and why it fits your home before you decide. Same-day and emergency scheduling are available when waiting is not an option.

Your old furnace is removed and your new system is installed to manufacturer specifications and local codes, covering gas or oil connections, ductwork, and controls. You get your home back clean when the crew leaves.

Your new furnace runs through a complete heating cycle before anyone leaves. You confirm it is heating correctly, get a walkthrough of the controls, and have your questions answered before the job is closed.

Nick was very knowledgeable & personable.
Universe is lucky ๐Ÿ€ to have such a great employee
We had a serviceman come to our house to check into our heating issues. Our burner is showing corrosion due to living near the ocean. We could either repair or replace. We are going to replace the system. The serviceman, Anthony was knowledgeable and not pushy.
This edit is in regards to a recent appt for my AC tune up. The fact that I keep getting rescheduled the day before my appt and after confirming is highly unprofessional. You also need to come up with a better response as to why you are rescheduling as your reps use the same line verbatim. Like everyone else my AC requires maintenance. I had to take days off of work to accommodate YOUR availability only to be cancelled each time, now twice! Its highly inappropriate and unprofessional. Do not bother making appts with this company!

April.2026 update. Alex came and did my tune up. He was very knowledgeable and professional. Thank you for all your time and help. Much appreciated!
Frank N was wonderful. He explained everything thoroughly.
Barney R 3 is wonderful, knowledgeable and professional person. I am very happy to work with him.

Bob was extremely knowledgeable and professional. Outstanding service.
I called at 1:15 in the morning due to my oil burner leaking oil. Dylan was at my home by 8:00 a.m to fix the problem. He knew what the problem was right away and fixed it. He was efficient and clean.
Jake was very professional and provided great details regarding services. I really appreciate the time and attention to details that he took.
The service was great and friendly, doesnt seem like there is any bull. A little expensive but worth it for the service.
Chester, the Universe Home Services HVAC technician, and Anthony the plumber, did an excellent job. These folks are highly recommended.
Just had new HVAC system and water heater installed by Universe home services. It was a very smooth process. Frank from sales gave us different options for installation. Explaining everything clearly. Ms. Tara answered all my follow up questions over the phone. They gave us a date for the job within couple of days of signing the contract. Keith and his crew arrived on time and explained how the process will go. They did a clean job and halled away the old equipment . Trevor the electrician inspected all the electrical work before leaving. They finished in one day as promised. I will recommend them
David was great. Explained everything that had to be done . Also gave me several options and a honest opinion. Thanks Dave

We are really happy with our service contract with Universe, it keeps our systems humming and costs reasonable. They come right away and are very clean and professional. It seems all plumbers make that claim but these guys actually are.

What Changes When You Replace Your Furnace

Long Island homeowners who replace aging furnaces notice the difference from the first heating season.

Long Island fuel oil prices and PSEG rates are among the highest in the country. When you replace a furnace that is 15 or 20 years past its efficiency peak, that gap shows up on your bill immediately. Most homeowners see a meaningful reduction from the first full heating season.

If you have been living with a bedroom that stays cold, a thermostat that never quite gets satisfied, or heat that varies noticeably between floors, that is not how it is supposed to work. A replacement correctly sized for your home fixes that. You set the temperature and the house reaches it.

Every homeowner with an aging furnace knows the feeling: October comes and you wonder if this is the year it fails. A new system with a manufacturer warranty behind it ends that calculation. You stop managing a declining asset and start expecting your home to be warm.

A large share of Nassau County homes still run on oil. Replacement is when most homeowners make the switch. No more delivery schedules, no storage tank, no exposure to oil price swings. Universe handles the full conversion as part of the job.

Why Long Island Homeowners Choose Universe for Furnace Replacement

The company you choose for your furnace replacement determines whether the job is done right and whether you have someone to call afterward.

Universe has earned the trust of Nassau and Suffolk County homeowners through honest work and consistent results.

Gas furnaces, oil furnaces, oil-to-gas conversions: your technician has done all of it in Nassau and Suffolk County homes. You get someone doing a familiar job, not figuring it out on yours.

Universe has been replacing furnaces in Levittown, Hicksville, Massapequa, and across Nassau and Suffolk County since 1954. Your technician draws on that history the moment they walk in.

The estimate is free. It covers your home’s actual heating load, your existing ductwork and fuel source, and your options. You know the cost and the reasoning before anything is scheduled.

When a furnace replacement surfaces a plumbing or electrical issue, you do not need a second contractor. Universe covers all three trades. One call.

Furnaces fail at night, on weekends, in January. Universe offers same-day replacement and 24/7 emergency response across Nassau and Suffolk County. Farmingdale, Rockville Centre, Huntington, Babylon: same response everywhere.

National Grid rebates apply to many furnace installations, especially oil-to-gas conversions. Universe identifies what you qualify for and handles the paperwork. You do not leave money on the table.

After the installation, Universe is still your number. Questions, service needs, maintenance: the same company that installed your furnace is the one you call.


Protect Your Investment with the Home Comfort Club

Your new furnace is worth protecting.

Most furnace failures that turn into emergency calls started as something small a fall tune-up would have caught: a heat exchanger showing early stress, an igniter near the end of its life, a filter so blocked the system is straining.

The Home Comfort Club schedules that visit automatically every fall, before the heating season begins. Members also get priority scheduling, a discount on repair work, and no dispatch fee when work is performed. Contact us to learn what the membership covers.

Is It Time to Replace Your Furnace?

Most furnaces communicate clearly when they are done. The question is whether you are listening.

Furnaces typically last 15 to 20 years. Many homes in Nassau County neighborhoods built during the postwar era, including Levittown, Massapequa, and Hicksville, are still running original equipment from the 1960s and 1970s. A furnace at that age is not just less efficient. It is carrying real failure risk through every winter that passes.

Homeowners in Merrick, Seaford, and Bellmore who find themselves scheduling furnace service every year are often past the financial threshold where repair makes sense. When the cumulative cost of keeping an aging system running approaches what a replacement costs, the calculation has already shifted.

Long Island homeowners pay some of the highest heating costs in the country between PSEG electricity rates and fuel oil prices. When your bills keep rising with no change in how you use the heat, your furnace is losing efficiency and making an already expensive situation worse.

A furnace that leaves rooms cold, produces banging at startup, or runs constantly without your home reaching the thermostat setting has stopped meeting your home’s demands. In Nassau County homes that have had additions or reconfigured layouts, an undersized or aging furnace makes these problems worse with every passing season.
