Furnace Replacement & New Heating Systems in Licking County
A new furnace should be sized for your house, not copied from the label on the old one. We measure, calculate, quote a firm price, and handle the permit and haul-away.

When it is time for a new furnace
Most gas furnaces in central Ohio last somewhere between fifteen and twenty-five years. The ones that last longest were sized correctly, got a filter change every few months and had a tune-up now and then. The ones that die early were oversized, starved for air or never serviced.
These are the signs we look at when a homeowner asks whether it is time:
- The furnace is past fifteen years old and needs a repair over a few hundred dollars.
- We found a cracked heat exchanger or corrosion in the combustion area.
- Gas bills keep creeping up while the thermostat setting stays the same.
- Some rooms are always cold, or the furnace runs constantly on cold days and never catches up.
- The furnace uses a standing pilot light and a natural draft into the chimney. Those are forty-year-old designs.
If you are on the fence, our repair or replace guide lays out the numbers.
Sizing: the step most installers skip
The most common mistake we see in Licking County homes is an oversized furnace. Someone replaced a 100,000 BTU furnace with another 100,000 BTU furnace because that is what was there, even though the house got new windows, attic insulation and siding since the original was installed. An oversized furnace heats the house in short bursts, shuts off, cools down and starts again. That short cycling wears out parts, wastes gas and leaves the house feeling drafty between cycles.
We size every replacement with a load calculation based on your square footage, insulation, windows, air leakage and ductwork. It takes longer than reading the old label, and it is the difference between a furnace that lasts twenty years and one that struggles.
A typical case: a 1990s two-story in Heath with a 120,000 BTU furnace heating about 2,000 square feet, where the load calculation comes in under 60,000. The homeowners assume the furnace is too small because the upstairs is always cold. It is the opposite. It blasted heat for three minutes, shut off, and the upstairs never got a steady flow. A correctly sized two-stage furnace runs longer, quieter cycles and the upstairs finally stays even.
Furnace quit and it is not worth fixing?
We can often install a new furnace within a day or two, and help with temporary heat in the meantime.
Choosing the right furnace
There are really three decisions to make: efficiency, how the burner and blower run, and whether to pair the furnace with a heat pump.
80% or 95%+ efficiency
An 80% furnace vents hot exhaust up a chimney or metal flue. A 95% or higher condensing furnace pulls so much heat out of the exhaust that it vents through PVC pipe and drains water. In most Licking County homes on natural gas, a condensing furnace pays back its higher price over its life, and federal efficiency rules are moving toward requiring condensing furnaces later this decade. Some homes, especially older houses with a furnace in a tight space and no easy path for PVC venting, are better served by an 80% unit. We will tell you which makes sense for your house.
Single-stage, two-stage or variable speed
A single-stage furnace is either fully on or off. A two-stage furnace runs on low most of the time and only goes to high on the coldest days, which means quieter, steadier heat. Variable-speed blowers move air more evenly and help with humidity control in summer when paired with central air.
Furnace plus heat pump
A dual-fuel setup pairs a gas furnace with a heat pump. The heat pump handles heating on mild days and the furnace takes over when it gets truly cold. It is a popular option for homeowners replacing an old air conditioner at the same time.
What installation day looks like
A standard furnace replacement takes one day. We protect floors from the door to the basement, shut off gas and power, remove the old furnace, set the new one, connect gas, venting, ductwork, condensate drain and wiring, and start it up. Before we leave, we measure gas pressure, temperature rise and combustion, check for carbon monoxide, and walk you through the new thermostat and filter.
A new furnace in Newark, Heath and most of Licking County requires a mechanical permit. We pull it with the city or the county building department and schedule the inspection. The old furnace goes on our truck, not the curb.
In a lot of Pataskala and Etna-area subdivisions built in the early 2000s, the original builder-grade furnaces are now twenty-plus years old and failing one after another. Most sit in basements with good access, which makes the swap straightforward, but we almost always find undersized return air. Adding a return during the replacement is often the best comfort upgrade the house will ever get.
Pricing and estimates
Replacement estimates are free. You will get a written quote with the equipment model numbers, efficiency ratings, warranty terms and everything included, so you can compare apples to apples. For typical ranges, see the Licking County HVAC cost guide. If your old furnace is still running and you are planning ahead, the weeks before the first hard freeze are the easiest time to get on the schedule.
Furnace replacement questions
How much does a new furnace cost in Newark, Ohio?
Most gas furnace replacements in Licking County fall between about $2,800 and $5,500 installed, depending on size, efficiency and how much venting or ductwork needs to change. A combined furnace and air conditioner replacement typically runs $7,000 to $13,000. We give you a written price before you commit.
How long does a furnace replacement take?
Most replacements are done in one day. Jobs that need a new venting path, new return ductwork or a switch from a chimney to PVC venting can take a second day.
Do I need a permit to replace a furnace in Licking County?
Yes. A furnace replacement requires a mechanical permit, whether through the City of Newark or the county building department for unincorporated areas. We pull the permit and schedule the inspection as part of the job.
Should I replace my air conditioner at the same time?
If the AC is more than about twelve years old, replacing both together usually saves money on labor and gives you a matched system that runs more efficiently. If the AC is newer, we can often keep it and match the new furnace to it.
What size furnace do I need?
The only reliable answer comes from a load calculation that accounts for your square footage, insulation, windows and air leakage. Copying the size of the old furnace is the most common way homes end up with oversized, short-cycling equipment.
