Furnace Installation in Upper Montclair
When a 90-Year-Old System Finally Calls It Quits
Gas Furnace Installation Upper Montclair, NJ
When a furnace installation goes right, you stop thinking about your heating system entirely. No cold spots on the second floor, no furnace cycling on and off every twenty minutes, no waking up at 2 AM to check the thermostat. You just come home to a warm house and that’s how it should be.
That matters more in Upper Montclair than it does in a lot of other places. The median construction year for homes here is 1938, which means a large portion of the housing stock was built before modern insulation standards existed. Large Victorian and Colonial Revival homes on the hillside above Bloomfield and Nutley lose heat faster than newer construction, and an undersized or worn-out system simply can’t keep pace with a drafty, multi-story pre-war home through a full New Jersey winter.
The right furnace properly sized for your actual home changes that completely. If your home is still running on an old oil system, a new high-efficiency gas furnace also opens the door to eliminating oil delivery altogether. For homes in the 07043 ZIP code that haven’t made the switch yet, that conversation alone is often worth having before anything else.
HVAC Contractor Upper Montclair, NJ
We’ve been doing this work in Essex County since May 15, 1973. That’s not a marketing number it means we’ve installed and replaced heating systems in the exact type of large, pre-war homes that line Upper Mountain Avenue and the streets around Bradford Elementary. We know what’s behind the walls of a 1910 Colonial Revival because we’ve worked in those homes for decades.
We’re family-owned and operated, hold NJ HVAC License No. 19HC00022600, and have earned a 5.0-star Google rating across more than 500 reviews. We’ve also been HomeAdvisor Screened and Approved for five consecutive years. We focus exclusively on HVAC no plumbing, no oil service, no distractions. Just heating and cooling, done well.
We offer free estimates, a workmanship guarantee, and financing through FTL Finance. If you need same-day service or you’re dealing with an emergency, we’re available 24 hours a day, seven days a week.
Furnace Replacement Process Upper Montclair
It starts with a free estimate. We send a technician to your home to look at your existing system and assess what you actually need not what’s easiest to sell. For older Upper Montclair homes, this step matters more than it does in newer construction. A large pre-war home has different load requirements than a mid-century ranch, and getting the sizing right upfront is what prevents problems down the road.
If your home still runs on oil, this is also when the oil-to-gas conversion conversation happens, because the two decisions are connected. Once you’ve agreed on the scope and equipment, we pull the required mechanical permit through the Township of Montclair Building Office that’s standard for any furnace installation in this area, and it’s not something you should have to manage yourself.
The installation itself is typically completed in a single day for a straightforward replacement. If the job involves converting from oil to gas, the timeline extends to account for PSE&G’s safety inspection, which is required after new gas equipment goes in. After the work is done, we test the system, schedule the permit inspection, and walk you through the new equipment. No disappearing act after the job is finished.

Heating System Installation Upper Montclair, NJ
Furnace installation in Upper Montclair isn’t a one-size-fits-all job. The homes here many of them built between the 1890s and 1930s in the Erwin Park area and along the corridors near the Upper Montclair and Mountain Avenue train stations have heating challenges that newer suburbs simply don’t. Original chimneys, old plaster walls, complex floor plans, and limited ductwork access all factor into how a modern furnace gets installed correctly. We work through those complications rather than around them.
We cover full system replacement, new furnace installation in homes converting from steam or hot water radiator systems, and oil-to-gas conversions for homes in the 07043 ZIP code that are ready to make the switch. We install and service all major brands, including Trane, Lennox, Weil-McLain, and Utica so if your current system is one of those, there’s no brand-related gap in the conversation.
Essex County falls within NJ Energy Subcode Climate Zone 4A, which sets minimum efficiency requirements for new heating equipment. Every installation we complete meets or exceeds those standards. Financing is available through FTL Finance for homeowners who’d rather spread the cost of a larger project over time.
How much does furnace installation cost for homes in Upper Montclair, NJ?
Furnace installation in Upper Montclair typically runs between $3,500 and $8,500 depending on the unit, efficiency rating, and scope of the job. If your home requires an oil-to-gas conversion rather than a straight furnace swap, the all-in cost in New Jersey generally falls in the $12,000 to $18,000 range that includes the new equipment, the gas line work, and the PSE&G safety inspection that’s required after installation.
The age and size of the home can affect the final number. A large pre-war Colonial Revival with limited existing ductwork is a more involved job than a straightforward like-for-like replacement in a newer home. The best way to get an accurate number for your specific property is to schedule a free estimate we provide those at no cost and no obligation, so you know what you’re looking at before any decisions are made.
My Upper Montclair home still has a steam radiator system can I switch to a furnace?
Yes, and it’s one of the more common projects in Upper Montclair. A large portion of the housing stock in the 07043 ZIP code was built before forced-air systems were standard, so steam radiator and hot water boiler setups are still running in homes all over the area. Converting from a steam or hot water system to a modern gas furnace is entirely doable, but it’s not a simple swap it requires installing ductwork throughout the home, which in a pre-war property with plaster walls and old framing takes more planning than it would in newer construction.
The payoff is significant. A modern high-efficiency gas furnace delivers more even heat distribution, better humidity control, and substantially lower operating costs compared to aging steam systems. We’ve been working in Essex County homes since 1973, which means this type of conversion in this type of home is familiar territory not an unusual edge case.
How long does a furnace installation take from start to finish?
For a standard furnace replacement pulling out the old unit and installing a new one in the same location with existing ductwork the installation itself is typically completed in a single day. The full timeline from your first call to a permitted, inspected, and operational system is usually a few days to a week, depending on permit processing through the Township of Montclair Building Office and equipment availability.
Oil-to-gas conversions take longer. If you already have an active gas line at the property, the process typically runs two to four weeks. If PSE&G needs to run a new gas line to the home, expect four to six weeks. That timeline accounts for PSE&G’s scheduling, the installation work itself, and the required safety inspection after the new gas equipment is in. We manage the permit and inspection coordination you don’t need to chase that down yourself.
What size furnace do I need for my older Upper Montclair home?
Sizing a furnace correctly is one of the most important parts of the job, and it’s where a lot of contractors cut corners. Too small and the system runs constantly without ever fully warming the space. Too large and it short-cycles turning on and off too frequently which causes uneven temperatures, poor humidity control, and premature wear on the equipment.
For Upper Montclair’s older homes, proper sizing is especially important. A 3,500- or 4,000-square-foot Victorian on the hillside above Bloomfield has very different heating requirements than a smaller, tighter modern home. The pre-war construction era meant minimal insulation by today’s standards, and homes on the eastern slope of the Watchung ridge tend to be more exposed to wind than valley-floor towns to the east. We assess your home’s specific conditions before recommending equipment not a ballpark guess based on square footage alone.
Do I need a permit for furnace installation in Upper Montclair, NJ?
Yes. Any furnace installation or replacement in Upper Montclair requires a mechanical permit issued through the Township of Montclair Building Office at 205 Claremont Avenue. This is a New Jersey Uniform Construction Code requirement, and it applies whether you’re doing a like-for-like replacement or a full system conversion. The permit process includes a post-installation inspection to confirm the work meets code.
You don’t need to manage this on your own. We pull the permit as part of the job it’s included in the scope of work. We hold NJ HVAC License No. 19HC00022600 and handle the permit and inspection coordination on every installation. If you’re also converting from oil to gas, there’s an additional PSE&G safety inspection required after the new gas equipment is installed, separate from the municipal permit inspection. Both get handled as part of the process.
How do I know if I should repair my old furnace or just replace it entirely?
The general rule in the HVAC industry is that if a repair costs more than half the price of a new system and the equipment is more than 15 years old, replacement usually makes more financial sense. But in Upper Montclair, there’s an additional layer to that conversation. Many homes here are running systems that are far older than 15 years some original to the home’s construction in the 1920s or 1930s. At that age, parts availability becomes a real issue, and efficiency is typically a fraction of what a modern high-efficiency unit delivers.
There’s also the oil-to-gas question. If your home is still on oil heat and the boiler or furnace is reaching end of life, a repair just extends the life of a system you’ll eventually replace anyway and delays the fuel cost savings that come with switching to gas. Our approach is to give you an honest assessment of what your system actually needs, not push you toward a replacement if a repair genuinely makes sense. The free estimate is the right starting point for that conversation.
