Should I Repair or Replace My Furnace?

While no one can predict exactly when your furnace will go out, there are a few clues that a furnace needs to be replaced.

How Old Your Furnace Is

Heaters usually last around 12–17 years. If yours is 10 years old or more, it has an increased chance of breaking down. You should start the process for replacing by researching new furnaces ahead of time.

Increased Energy Bills

Worn down furnaces won’t be as efficient. If yours hasn’t undergone preventative furnace maintenance, you risk losing further furnace efficiency and dealing with steeper energy costs.

Frequent Repairs

You should think about replacing your furnace if yours need repairs more consistently.

Spotty Heating

An older furnace system can struggle to properly heat your home. Leaky ductwork and a dirty furnace filter can also stir up trouble.

Three Benefits of a New Furnace

While furnace installation can feel intimidating, new furnaces include new features worn down systems can’t compete with. In addition, you’ll be able to relax knowing you won’t have to replace your system for years to come.

A new furnace should provide:

Improved Efficiency

Todays furnaces are very resilient and offer higher efficiency ratings versus systems from 20 years ago.

Quieter Operation

A newer furnace includes the latest in quiet operation technology. You won’t always notice when it starts running.

Peace of Mind

Modern HVAC technology ensures your heating will last longer and run with increased energy efficiency. With our service agreements, you’ll never lose out on an important annual tune-up again.

What to Expect From Willco's Furnace Installation Process

01

It’s Easy to Contact Us

Call, text, chat, or schedule an appointment directly from our website. You can even use our instant online quote tool to start pricing out options right away.

When you reach out to Willco, our office staff sees that message and responds as quickly as possible. We’ll ask some questions to understand your goals and concerns before the appointment, allowing us to show up prepared.

02

In-Home Evaluation & System Selection

A new furnace should fit the house, not just the square footage on paper. We look at your current system and fuel supply, floor plan, ductwork or radiators, insulation and windows, and the comfort problems you have been living with.

03

Furnace Sizing

There is a big difference between installing a new system and installing the right one. A furnace that is too small keeps up in November and loses ground in a January cold snap. One that is too large short-cycles, wastes fuel and leaves the far rooms cold. Winter design temperatures across our service area run from about 3F in Sussex County, the coldest in New Jersey, to 8F in Passaic County, so capacity that works elsewhere in the state can fall short here.

04

Clear Pricing & Financing

Price matters, and we recognize that homeowners want to know exactly what they’re paying for before committing.

When presenting options, we’ll walk you through the choices, explain the value behind certain equipment and the installation process, and present financing options. Helping you make smart decisions for your home and budget always takes priority over making a sale.

05

Installation Day & Follow-Through

Willco technicians are trained to arrive prepared, protect work areas, wear booties indoors, and leave your home the way they found it. We provide clear arrival windows and keep you updated if that ever changes.

06

Long-Term Support

Once your new furnace is installed, the relationship does not suddenly end. We have built our reputation on answering the phone and making things right when something needs attention, which matters most on a purchase this size.

Heating System Types

There is no one-size-fits-all answer for heating. When we come out for an estimate, our goal is to match the right system to the home and the homeowner.

Gas Furnaces

For homes on a natural gas main, a high-efficiency gas furnace is usually the most economical option. Condensing models reach the 90%-plus AFUE range, though they vent differently than an older unit.

Propane Furnaces

Common across North Jersey wherever the gas main does not reach. Propane is a delivered fuel, so correct sizing matters more. An oversized furnace works through a tank faster than one matched properly.

Oil Furnaces

Fuel oil still heats a large share of homes in the parts of Sussex and Warren counties that sit beyond the gas main. A modern oil furnace is often the right answer when there is no gas main nearby and the tank and lines are sound. We also handle oil to gas and oil to propane conversions.

Factors That Affect Furnace Installation Cost in North Jersey

Pricing varies, and we know that’s often the biggest concern for homeowners. Here’s what can affect the cost of your new system:

✓Home size and layout
✓Ductwork condition or design
✓Brand and energy efficiency of the unit
✓Type of heating system being installed
✓Zoning or smart thermostat upgrades
✓Permits or local code requirements

Willco is not trying to be the cheapest name on the list. Our focus is quality work, fair pricing, and long-term trust. That’s why we offer financing options to help spread out the cost and consider available rebates and incentives when making recommendations.

Furnace Installation FAQs

There is no single number, because the cost depends on the fuel you are on, the efficiency and staging of the equipment, the size and layout of the house, the condition of your ductwork, whether venting or a chimney liner needs work, and permit fees. We give you a written, flat-rate estimate after we have seen the house, and financing is available at no added cost to your proposal.

Age, repair history and parts availability usually settle it. Under about twelve years with a first significant repair, repairing generally makes sense. Past fifteen, with repeated failures or parts that are getting hard to source, replacement is normally the better use of the money. We will give you an honest read during a free evaluation, including when a repair is the right call.

It depends on what is available at your address. Natural gas service is common across much of Morris County and in the larger Sussex and Warren boroughs, while many outlying streets are on delivered fuel instead. We install gas, propane and oil furnaces, and we handle oil to gas conversions where a main is available.

Winter design temperatures across our service area range from 3F in Sussex County, the coldest of any county in New Jersey, to 8F in Passaic County. An undersized furnace keeps up in mild weather and falls behind in a cold snap. An oversized one short-cycles, which wastes fuel, wears out the ignition and heat exchanger sooner, and leaves rooms furthest from the air handler cold. We size from the house rather than from the label on the old unit.

Yes. We work across Sussex, Morris and Warren County and nearby North Jersey communities from our Branchville shop. You can find your own town in the service area list further down this page, and each town links to a page with the local detail.

Yes, through NEIF and Service Finance Company, at no additional cost added to your proposal. Options include interest-free promotional terms and longer plans with lower monthly payments. We will walk through what you qualify for during the estimate.

We had transferred from oil to gas AND we had an air conditioner unit installed. They were 2 big jobs and we ran into some trouble. I can say that Willco was very responsive and I felt they cared about us. Their goal of a job well done is evident in how they operate. I would definitely recommend them.
