If your furnace has reached the end of the line, the replacement is your chance to fix the things that annoyed you about the old one: the cold back bedroom, the noise, the fuel bills. We install gas furnaces for homes throughout North Jersey and treat the ductwork as part of the job, not an afterthought.
Heights Plumbing, Heating & Cooling is family owned and operated, licensed and insured, and our mechanical engineer sizes each system from a heat loss calculation. We also do our own electrical work, so the install is handled by one crew from start to finish.
Why A New Furnace Sometimes Disappoints
Homeowners spend real money on a new furnace and are surprised when the comfort problems stay exactly the same. That usually happens for one of two reasons. The furnace was sized off square footage or off the old nameplate, so it is oversized and short cycles. Or the ductwork was never right in the first place, and no amount of new equipment fixes undersized returns and leaky trunk lines.
A high-efficiency furnace also changes the venting and condensate requirements, and it needs a properly matched airflow setup to actually reach its rated efficiency. Skipping any of that turns a good piece of equipment into an expensive disappointment.
What Our Furnace Installation Service Includes
We begin with a load calculation and a look at the whole system: the ducts, the returns, the filter location, the venting path, the gas line and the electrical. From there we recommend a furnace with the right capacity and staging, and tell you honestly whether duct modifications are needed to get the performance you are paying for.
On install day we disconnect and remove the old unit, set the new furnace, connect gas, venting and condensate, make our own electrical connections, adapt the plenum and ductwork, fit a proper filter arrangement and install the thermostat. We pull the permit, handle the inspection, then set gas pressure, measure temperature rise and static pressure, and verify the unit is running within the manufacturer specification before we hand it over.
Signs You Need A New Furnace
- Furnace is 15 to 20 years old or older
- A cracked or corroded heat exchanger was found
- Repairs are becoming routine every winter
- Loud operation you have simply learned to live with
- Rooms that never reach the thermostat setting
- Rising gas bills with no change in usage
- Rust, soot or moisture around the unit
- Replacement parts no longer readily available

Our Furnace Installation Process
Survey and load calculation
We measure the home and run a heat loss calculation, and inspect the ductwork, returns and venting before recommending anything.
Equipment selection and quote
We present suitable furnaces with upfront pricing, explain the differences between single-stage, two-stage and modulating, and let you choose.
Permit and scheduling
We pull the required permit and schedule the install, giving you a realistic timeline and an on-time arrival window.
Installation day
Old unit out, new furnace in, with gas, venting, condensate, plenum work, filter setup and our own electrical connections all handled by our crew.
Startup, testing and inspection
We set gas pressure, verify temperature rise and static pressure, walk you through the thermostat and meet the town inspector.
Furnace Options We Offer
High-efficiency condensing furnaces
Sealed combustion units that vent through PVC and recover more heat from the same fuel. These require condensate drainage and correct venting.
Two-stage and modulating furnaces
Units that run longer at lower output, which means steadier temperatures, quieter operation and fewer hot and cold swings.
Standard-efficiency replacements
A practical choice where venting, chimney or budget constraints make a condensing furnace impractical.
Furnace plus AC system replacement
Replacing both at once so the furnace blower, coil and condenser are properly matched and the whole system performs as designed.
Ductwork modification and sealing
Correcting undersized returns, leaky trunks and bad transitions, because the duct system decides how the furnace actually performs.
Oil-to-gas furnace conversions
Moving a home off oil heat, including equipment, gas piping, venting and permits handled as one project.

Furnace Installation FAQs
How long does a furnace installation take?
A straightforward changeout is often completed in a day. Jobs involving new venting, ductwork changes or a fuel conversion take longer, and we tell you the timeline before we start.
Do I need to replace my ductwork too?
Not always. We inspect the ducts and returns as part of the assessment and only recommend changes where they are limiting performance. We will show you what we found.
Should I replace the air conditioner at the same time?
If the AC is a similar age, doing both together lets us properly match the blower, coil and condenser and usually saves on labor. If the AC has years left, there is no need to rush it.
What efficiency rating should I get?
It depends on your venting, how long you plan to stay and your fuel use. We lay out the payback honestly rather than pushing the most expensive unit on the list.
Do you remove and dispose of the old furnace?
Yes, removal and disposal of the old equipment is part of the installation, and we leave the work area clean.
