5 Best Furnace Brands Compared in 2026
The short answer
The best furnace brands for your shortlist depend on the full model, load and installation scope. These five named families compare two-stage gas heat, blower type and documented limitations. The order is a reading order, not a reliability league table.

The best furnace brands offer more than one kind of furnace. Compare a named model family. Units with the same badge may have different features. These five candidates give you useful questions for equal-scope bids. We read the makers' model records. We checked the warranty terms too. We have not tested these furnaces in homes or ranked their long-term failure rates.
1. Carrier: Performance 96, 59TP6
Carrier Performance 96, 59TP6
Our verdict:
Two-stage comfort with service options
Consider when you value two-stage heat and can compare the written parts and labor options.
Compare Carrier costs- Up to 96.7% AFUE
- Two-stage heat; variable-speed blower
- Warranty choices depend on dealer participation
Keep in mind: Data sharing for remote diagnostics is optional; eligible sizes and emissions limits need checking.
Product details checked October 2026
Carrier's 59TP6 model page describes a two-stage furnace with a variable-speed blower and up to 96.7% AFUE. Two heat stages let the flame run low or high. Blower speed is a different feature. Compare both fields on a bid rather than treating the words as one system.
Consider this family if you value comfort controls. Get the warranty options in writing too. Carrier's remote fault checks need a thermostat that works with the unit. They also need your consent to share data.
That is an optional service choice, not a condition we assume for every home.
You still need to check the exact size. Check local emissions rules and dealer terms too. The page limits its certified ratings by size and position. Ask for the full suffix and supporting rating record.
Use our Carrier furnace cost guide to compare what the proposal includes.
2. Lennox: EL297V
Lennox EL297V
Our verdict:
Two-stage heat with variable airflow
Consider for a condensing replacement where variable airflow is useful.
Compare Lennox costs- Up to 97% AFUE
- Two-stage heat; variable-speed blower
- Exact controls and installed scope need a quote
Keep in mind: A family efficiency ceiling is not the rating of every capacity; verify the full model.
Product details checked October 2026
The Lennox EL297V pairs two-stage heat with a variable-speed blower. Lennox publishes an efficiency ceiling of 97% AFUE. That ceiling describes the family. So the quoted capacity still needs its own rating and install check.
Put it on your shortlist when you want two-stage heat and a bid that explains variable airflow. Ask which control is included and whether the quoted setup uses any linked-system features. A new control can affect both the unit package and the scope of setup work.
The maker's price symbol is relative. It does not give you a dollar quote. Do not turn it into a national price tier. Our Lennox furnace cost guide shows how to compare models, controls and installed scope without assigning an unproven price.
3. Goodman: GR9T96
Goodman GR9T96
Our verdict:
Two-stage heat with multi-speed airflow
Consider when you want two heat stages without assuming the blower is variable-speed.
Compare Goodman costs- Up to 96% AFUE on current family page
- Two-stage heat; multi-speed ECM blower
- Upflow/horizontal family; check full suffix
Keep in mind: Published warranty summaries differ by date. Use the certificate supplied with the full model.
Product details checked October 2026
Goodman's current GR9T96 page describes two-stage heat and a multi-speed ECM blower, with up to 96% AFUE. Multi-speed is not the same claim as the variable-speed blower on the other named candidates. Read that distinction on each bid. Keep the exact blower claim tied to the model.
Consider this family when two heat stages matter and the installer can record the full model and fit. GR means the upflow/horizontal family. A different cabinet position needs the correct model. A bid that says only Goodman 96 leaves too much unstated.
Warranty terms can change. The date and version of the record matter. We do not substitute an older lifetime claim for a current certificate. Ask the installer to attach the exact terms for the supplied unit. See the Goodman furnace cost guide for the unit-versus-install comparison.
4. Rheem: R962V
Rheem R962V
Our verdict:
Four-way installation configuration
Consider when cabinet orientation is a key constraint.
- 96% AFUE family
- Two-stage heat; variable-speed airflow
- Four-way multi-position design
Keep in mind: Fit and emissions compliance need the exact model and local installation assessment.
Product details checked October 2026
Rheem's R962V family record names two-stage heat, variable airflow and a four-way multi-position design. Its family efficiency is 96% AFUE. The linked SKU is one family member. It does not suit every heating load.
Consider it when the cabinet position matters to the job. Ask if the quoted position suits that model's instructions. Find out if the drain or duct joint needs to change. A flexible family does not make every existing installation suitable.
The drawback is that family features alone do not settle site fit or total cost. Keep those decisions in the written scope. We do not claim a price for your home. Nor do we promise that stock is available.
5. Trane: 96 Two-Stage Variable Speed, formerly S9V2
Trane 96 Two-Stage Variable Speed, S9V2
Our verdict:
A documented two-stage alternative
Consider as another two-stage bid with the same load and installation scope.
- 96% AFUE in Trane brochure
- Two-stage heat; variable-speed blower
- Name formerly S9V2 in current lineup
Keep in mind: Do not confuse it with the 97 model formerly S9V2-VS.
Product details checked October 2026
Trane's gas furnace brochure maps the 96 Two-Stage Variable Speed furnace to the former S9V2 name. It is a two-stage, 96% AFUE candidate. Do not confuse it with the 97 model, formerly S9V2-VS.
Use this candidate to obtain another bid for the same load and scope. A full model code matters more than a shortened series name. Ask for the stated rating, the covered-parts terms and separate labor terms with that proposal.
The limitation is that a brochure's claims do not prove this unit lasts longer than another brand. A ranking of failure rates needs fair data from an outside source. None is asserted here, and there are no customer-star scores in our selection basis.
Factors to consider when choosing the best furnace brands
Match the unit to a stated heating load before comparing features. ACCA Manual J addresses that load. Size, orientation, airflow and venting remain separate fit checks. An efficiency ceiling alone cannot choose the unit.
| Decision | Evidence to request | Why it matters |
|---|---|---|
| Capacity | Full model and load report | A family name does not establish output |
| Comfort | Heat stages, blower and controls | Similar words can describe different features |
| Rating | Exact model's published rating | Family ceilings need qualification |
| Installation | Included and excluded work | Equipment prices are not installed totals |
| Warranty | Current certificate and labor terms | Parts coverage does not define every service cost |

Use the furnace replacement cost calculator once each bid has a clear scope. Compare bundles as bundles, or separate unit and labor as separate costs. Keep any unpriced venting, ducts or electrical work beside the result.
FAQ
Which furnace brand is the most reliable?
These sources do not support a like-for-like brand-wide failure ranking. The shortlist uses the makers' stated features. It shows their limits too. Ask about local parts support, install records and written service terms when comparing bids. A long parts warranty and a low failure rate are different things; do not treat one as proof of the other.
Is a higher AFUE always the right choice?
Not by itself. A higher rated efficiency can be useful, but your installed cost, fuel use and site fit still matter. A condensing replacement may change venting and drainage scope. Compare those costs and the full model before making a choice.
No household savings amount is promised here.
Can I compare two-stage models across brands?
Yes, if the load, airflow and installed scope are like-for-like. Check the blower separately from the gas valve. Include controls, needed site work and labor terms. Two proposals with the same heat stages can still differ in cabinet fit, unit package and what the installer has agreed to do.
