Furnace replacement prices, published up front
Most HVAC companies won't say a number until someone is standing in your basement. We publish ours, so you know whether you're looking at a repair or a replacement budget before you call. These are installed prices, before rebates:
New gas furnace
$2,000 – $4,000A new gas-fired furnace, installed and tested, tied into your existing ductwork, gas line and venting.
Furnace + AC combo
$6,500 – $8,500Furnace, coil and condenser: a complete new heating and cooling system, installed in one project.
Not sure it needs replacing?
$150A service call with a full diagnosis, so you know exactly what's wrong and what the repair costs before you decide.
How to read these numbers: they're planning ranges based on the equipment we install most often. The firm price depends on the BTU size of the furnace your home needs, the efficiency rating you choose, and how much venting, gas piping or ductwork has to change. We give you a written number after we see the system, and nothing starts until you approve it. Full breakdown on our HVAC pricing page and in the new furnace cost guide.
Every furnace replacement includes
- Free in-home estimate with a written price
- Furnace sized to your home, not to the old nameplate
- New venting, gas and condensate connections as needed
- Carbon monoxide and safety testing before we leave
- Utility rebate paperwork filed for you
- 10-year manufacturer parts + 5-year Lumen labor warranty
- Financing for every credit profile

Repair or replace your furnace? The honest math
A well-maintained gas furnace usually lasts 15–20 years. Skip maintenance and that can drop to 10–12. Age alone isn't a reason to replace a furnace that runs well, but age combined with a big repair bill usually is.
A common rule of thumb: if the repair costs more than a third of a replacement and the furnace is past 12–15 years old, replacement usually wins. With a new furnace at $2,000–$4,000, that means a $700+ repair on an old unit deserves a second look.
Signs your furnace is near the end
- Repairs every season instead of every few years
- Rising gas bills with no change in how you use the heat
- Uneven heat, long run times or short cycling (turning on and off constantly)
- A yellow burner flame instead of blue, or rust and cracks around the unit
- It's 15+ years old and the current repair quote is a big one
If the honest answer is "repair it," that's what we'll tell you. Our furnace and boiler repair service call is $150 and includes the full diagnosis. If your furnace won't start right now, run through our 5 checks before you call first, and read how long a furnace lasts for the longer version of this math.
How a Lumen furnace replacement works
1. Call, text or send the request form
Call or text (267) 252-2969 any time, day or night, or use the form on this page. Tell us the age of your furnace if you know it and what it's doing. If you've lost heat, say so and we treat it as an emergency.
2. Free in-home estimate
We look at the furnace, the venting, the gas line and the ductwork, and size the new unit to your home. You get a written price, the rebates your utility pays on the model we're quoting, and your financing options, all before you commit to anything.
3. Installation, done to code
Our crew removes the old furnace and installs the new one with the venting, gas piping and condensate drain it needs, then ties it into your ductwork and seals the connections. Every installation is safety-tested, including carbon monoxide checks, before we leave.
4. We file your rebates
Rebate programs have efficiency rules and filing deadlines. We install equipment that qualifies, document it, and submit the applications for you.

Choosing the right replacement furnace
Size it to the house, not the old label
The furnace that came out of your basement isn't proof of what your home needs. Houses get new windows, insulation and additions, and plenty of original furnaces were oversized to begin with. An oversized furnace short-cycles: it heats the house in quick bursts, wears out its parts early and leaves rooms uneven. We size the new furnace to your home so it runs in steady, efficient cycles.
Efficiency: why 95% AFUE is the number to know
AFUE is the share of the gas you pay for that becomes heat in your home. A 95% AFUE furnace turns 95 cents of every gas dollar into heat. High-efficiency furnaces cost more up front, burn less gas every winter, and are the models the rebate programs pay on. PGW's $400 furnace rebate requires 95%+ AFUE, and Energize Delaware's furnace rebate requires 96%+ AFUE. High-efficiency furnaces vent through PVC pipe and drain condensate, which we plan for on the estimate.
Brands we install
Recent furnace replacements on our recent work page include Lennox, Goodman and Coleman gas furnaces. We quote the model that fits your home, your budget and the rebate rules, and we check ENERGY STAR certification before you sign whenever a rebate is part of the plan.
Basements, attics and crawlspaces
Furnaces in the Philadelphia area live everywhere: tight rowhome basements, attics and crawlspaces with barely enough clearance. We've done all three. Low-clearance installs take careful layout, because every connection still has to be serviceable once the equipment is in.
Replacing the AC or water heater at the same time
If your air conditioner is the same age as your furnace, replacing both in one project saves labor and gives you a matched system. That's our furnace + AC combo at $6,500–$8,500. If the water heater is also near the end, doing it in the same visit shares the venting and gas work. A standard water heater adds $1,500–$2,000.
No ductwork? A furnace may not be the answer
Many older Philadelphia rowhomes were built around radiators, not ducts. If your home heats with a boiler, see boiler and heating system installation or read boiler vs. furnace for Philadelphia rowhomes. If you're weighing electric heat, a heat pump installation heats and cools from one system, and in Delaware a hybrid heat pump + furnace system earns one of the larger rebates.
Furnace rebates in PA, NJ and Delaware
Utility rebates cut the cost of a high-efficiency furnace, and we file the paperwork for you. Rebates pay only on ENERGY STAR certified equipment, so we quote qualifying models whenever a rebate is part of your plan.
- Philadelphia (PGW EnergySense): $400 on a 95%+ AFUE gas furnace. Income-qualified households can get up to $800. The program runs through August 31, 2027.
- New Jersey: high-efficiency gas furnaces qualify for utility rebates of 30% of cost, up to $600 per unit. A furnace + AC combo can claim both.
- Delaware (Energize Delaware): $350–$750 on a 96%+ AFUE gas furnace, more when replacing an 89% or older unit. A hybrid heat pump + furnace system pays $1,450–$2,250. Delaware rebates start with a $50 home energy assessment.
The federal tax credit is gone. The 30% Energy Efficient Home Improvement Credit ended on December 31, 2025. If a company is still selling a new furnace on that credit in 2026, it isn't available. The utility rebates above are what's real. See every program on our current rebates page.
Financing a new furnace
Approved credit finances through Joist homeowner financing. Bad or limited credit goes through Microf, a lease-purchase program that approves without a traditional credit score (available in PA and DE; not offered in NJ). Both are arranged on the free estimate visit.
I honestly never write reviews, but Lumen absolutely deserves one.
I needed a new gas furnace and they were fast, professional, and had the best price by far. I shopped around, got multiple quotes, and nothing even came close. From the first call to installation, everything was smooth and stress-free.
The team showed up and got the job done quickly. No pressure, —just honest, quality work.
If you're searching around like I was, stop searching and call them ASAP. You won't do better.
Nat Alie
Mark and team did a great job. We lost heat during the coldest week of the year and he came out immediately and did an urgent installation and was flexible about scheduling. He was fair and transparent about price and really clear about what he was doing. We definitely plan on working with him in the future if other repairs are needed. Highly recommend!
Lucy Gleysteen
We hired Lumen Heating & Cooling to replace our entire HVAC system, including a new furnace, air conditioner, ductwork, and thermostat. From the estimate to the installation, the entire process was smooth and professional. The crew was knowledgeable, respectful, and paid attention to every detail.
The quality of the work exceeded our expectations, and our home is more comfortable than ever. If you're looking for a trustworthy HVAC contractor in Media, PA, Wayne, PA, or the surrounding areas, I highly recommend Lumen Heating & Cooling. They provide excellent customer service, fair pricing, and top-quality workmanship. We will definitely use them again for any future heating and air conditioning needs.
