We've installed furnaces in the Philadelphia area since 2001. Here's what the tier list actually looks like from the contractor side of the business.

The honest answer: most major furnace brands make equipment that will heat your home reliably for 15–20 years if sized correctly and installed properly. The brand matters less than you think. What matters more: proper sizing, quality installation, and parts availability when something eventually breaks.
That said, there are real differences between tiers, and some brands make service harder and more expensive than it needs to be. Here's how the market breaks down from our perspective after 25 years of installs in Philadelphia, Montgomery County, and Bucks County.
These brands make excellent equipment. Variable-speed motors, high modulation ratios, quiet operation, advanced humidity control. Carrier's Infinity series, Lennox's SLP99V, and Trane's S9V2 are genuinely impressive pieces of equipment. Installed cost: $9,100–$14,500 for high-end models. The tradeoff: proprietary controls and thermostats that require their own dealer to service, higher parts costs, and repair bills that can run 30–50% more than a comparable York or Goodman repair.
This is where McCorry does most of its work. York and Goodman hit 96%+ AFUE at price points $1,950–$3,900 below premium brands. Parts are available from multiple suppliers. Any qualified tech can service them. Warranties are strong: 10-year parts when registered, lifetime heat exchanger on select York models. Installed cost: $5,800–$9,800 for high-efficiency models. Real-world performance for a typical Philadelphia home is virtually identical to premium brands — the difference shows up in comfort features (humidity control, variable speed) not in reliability or longevity.
Goodman's entry-level single-stage 80% AFUE models start around $4,900 installed. For rental properties or homes where the owner wants the lowest upfront cost and a working furnace, these are fine. For a primary residence in the Philadelphia area where you're heating 150+ days a year, the efficiency penalty adds up fast and the single-stage operation is noticeably less comfortable. Spend the extra $1,050–$1,550 for the 96% two-stage version.
We've worked on every major brand since 2001. Our decision to stock and install York and Goodman comes down to four things:
The problem isn't always a "bad" brand. It's proprietary ecosystems. Some manufacturers build thermostats, controls, and communicating systems that only work with their own equipment and can only be serviced by their own dealers. That's fine when the system is new and the dealer is responsive. It becomes a problem when:
We're not naming names here because the situation changes. Ask your contractor directly: "Can any qualified HVAC company service this equipment, or does it require your specific dealer?"
After the brand question, these factors have a bigger impact on how your furnace performs and how long it lasts:
An oversized furnace short-cycles: it heats the space too quickly, shuts off, and repeats. This creates temperature swings, excessive humidity in summer, premature heat exchanger wear, and higher utility bills. Sizing requires a Manual J load calculation based on your home's square footage, insulation levels, window area, and air leakage. Rule of thumb sizing (1,000 sq ft per ton, etc.) is not accurate enough.
A 96% AFUE furnace installed with a leaky duct system effectively performs like an 80% unit. Proper sealing, correct static pressure, right-sized ductwork, and accurate refrigerant charge (if a heat pump or AC is involved) determine real-world efficiency. A good installer pulls permits, does a combustion analysis, and sets up the airflow correctly.
Annual tune-ups catch failing ignitors, cracked heat exchangers, and blocked flue passages before they become emergencies. A $200 annual maintenance visit can prevent a $1,550 emergency service call in January.
| Brand Tier | Example Models | Installed Cost (Philadelphia) | McCorry Installs? |
|---|---|---|---|
| Premium | Carrier Infinity, Lennox SLP99V, Trane S9V2 | $9,100 – $14,500 | Carrier yes, others on request |
| Best Value | York YP9C, Goodman GMVC96, Rheem R96V | $5,800 – $9,800 | Yes (primary brands) |
| Budget | Goodman GMSS92, entry-level single-stage | $4,900 – $6,500 | Yes, with caveats |
For most Philadelphia homeowners, York and Goodman offer the best value: solid warranties, readily available parts, and straightforward repairs. Premium brands like Carrier, Lennox, and Trane perform well but cost $1,950–$3,900 more upfront with marginal real-world efficiency differences.
We install Carrier from the premium tier when customers want it. We steer most customers toward York and Goodman because parts are available from multiple suppliers, repairs are straightforward for any qualified tech, and the value-to-performance ratio is better for typical Philadelphia homes.
Avoid brands with proprietary parts that only their own dealers can source. When your furnace breaks at 11pm in January and needs a part, you want options. Some brands deliberately restrict parts distribution to force customers back to their dealer network.
No. A correctly sized and properly installed mid-range furnace will outperform a premium brand installed wrong. Manual J load calculation, proper duct sizing, correct refrigerant charge, and sealed connections matter more than the nameplate on the equipment.
With annual maintenance, York and Goodman furnaces typically last 18–22 years in the Philadelphia area. Both brands carry 10-year parts warranties when registered within 60 days of installation.
