Is a Bryant Evolution furnace worth it over a Legacy?
A Bryant Evolution is worth it over a Legacy if you'll stay put and want steadier, quieter heat; the gain is mostly comfort, not gas savings. The 987M modulates with a variable-speed blower, while Legacy furnaces are single-stage and simpler to repair. Many buyers land on a two-stage Preferred instead.
Key points
- Bryant has three furnace tiers: Legacy (entry), Preferred (middle) and Evolution (top). The model number tells you which one you have.
- The Evolution 987M is modulating with a variable-speed blower, rated by Bryant up to 98.5% AFUE. Legacy furnaces are single-stage.
- The efficiency gap between a condensing Legacy and an Evolution is small. The difference you feel is steadier heat and quieter operation.
- Bryant's parts and heat exchanger warranties depend on registering within 90 days, on both lines.
- For most Minnesota homes a two-stage, variable-speed Preferred furnace is the value sweet spot.
A Bryant Evolution furnace is worth the extra money over a Legacy when you plan to stay in the house and care about steadier, quieter heat. The Evolution 987M modulates its flame and runs a variable-speed blower, so it holds temperatures evenly through a Minnesota winter. It won't cut the gas bill much compared with a condensing Legacy, because the rated efficiency gap is small. Many buyers land in the middle, on a two-stage Preferred furnace.
What are Bryant's three furnace tiers?
Bryant is owned by Carrier Global and shares much of its engineering with Carrier. It sells furnaces in three tiers: Legacy at the entry level, Preferred in the middle and Evolution at the top. Our Bryant brand page covers the whole lineup, and the Bryant vs Carrier comparison explains how the two brands line up.
Bryant's model numbers do the sorting for you. On current furnaces, a model that starts with 8 is an 80% furnace venting into a metal flue, and one that starts with 9 is a condensing furnace venting through PVC. The last letter usually gives the burner type: M for modulating, T for two-stage, S for single-stage. The table compares a few current models using Bryant's published ratings (checked September 2026):
| Model | Line | Burner | Blower | Rated AFUE |
|---|---|---|---|---|
| 987M | Evolution | Modulating | Variable-speed | Up to 98.5% |
| 926T | Preferred | Two-stage | Variable-speed | Up to 96.7% |
| 916S | Legacy | Single-stage | Multi-speed ECM | Up to 97% |
| 912S | Legacy | Single-stage | Fixed-speed | Up to 92.1% |
| 800S | Legacy | Single-stage | Fixed-speed | 80% |
Bryant's Evolution and Preferred variable-speed blowers adjust to hold a set airflow. The Legacy 916S uses a multi-speed constant-torque motor that's set at installation, which is a step up from an old single-speed blower but doesn't adjust itself.
What modulation changes in a Minnesota January
A furnace is sized for the coldest days, but most of the heating season is far milder than that. A single-stage furnace runs at full fire every time it starts, even on a 30°F November afternoon. It heats the house quickly, shuts off, the house drifts down, and it starts again. You feel that as warm blasts and cool gaps, and upstairs rooms in a two-story swing more than the main floor.
A modulating furnace like the 987M adjusts its fire to the load. On a mild day it runs low and long. On a -20°F night it runs near full. Longer, lower cycles mean:
- Steadier temperatures from room to room, and less difference between floors
- A quieter blower most of the time, since it rarely runs at full speed
- More air passing through the filter and past the humidifier, which only works while the blower runs. See our whole-home humidifier guide for why that matters in a dry Minnesota winter.
A two-stage Preferred furnace gets you much of that benefit: a low stage for most days and a high stage for cold snaps. Our post on the quietest furnaces goes further into staging and noise.
Venting is the same story on either line. Every 9-series furnace vents through PVC out a side wall or the roof, needs a condensate drain and, on direct-vent installs, a combustion-air pipe. In Minnesota those pipes need the snow kept off them, because a drift over the intake or exhaust can shut any condensing furnace down, and a condensate line run along a cold rim joist can freeze in deep cold. Our post on a frozen furnace condensate line covers that one. Moving from an old 80% furnace to any condensing Bryant can also leave the water heater alone in an oversized chimney, which may need a liner. That belongs in the quote whichever tier you pick.
What modulation doesn't change much is the gas bill compared with a condensing Legacy. The rated efficiency gap between 97% and 98.5% is small. The big savings come from moving off an old 80% furnace, as our AFUE explainer shows.
Living with each line
| Question | Legacy | Evolution |
|---|---|---|
| How it heats | Full fire every cycle | Modulates to match the load |
| Blower | Fixed-speed, or multi-speed ECM set at install | Variable-speed, adjusts itself |
| Thermostat | Any standard 24-volt thermostat | Evolution Connex for the communicating features |
| Fault codes | Status light on the furnace board | Fault history readable at the wall control |
| Repair parts | Simplest and cheapest | Variable-speed motors and boards cost more |
| Best fit | Rentals, tight budgets, simple houses | Larger two-stories, zoned systems, heat pump pairing |
What controls does a Bryant Evolution furnace use?
The Evolution furnaces pair with Bryant's Evolution Connex control, a communicating thermostat. Bryant lists features such as Perfect Heat, which manages how the furnace runs for steadier comfort, and Perfect Humidity, which handles summer moisture removal when it's matched with a Bryant air conditioner or heat pump. The communicating setup also stores fault history, which we read first when something goes wrong.
The trade-off is repair cost. Variable-speed motors and communicating boards cost more to replace than simple parts. For a sense of scale, national cost guides such as HomeGuide put a variable-speed (ECM) blower motor at $800–$2,300 and a standard PSC blower motor at $500–$1,400. A Legacy furnace is the simplest Bryant to repair, which is one reason we like it for rentals.
What warranty do Bryant Evolution and Legacy furnaces carry?
Bryant's product pages for the 987M and 916S (checked September 2026) list the same core coverage when the furnace is registered on time:
- A 10-year parts limited warranty with registration within 90 days, dropping to five years if it isn't registered
- A lifetime limited heat exchanger warranty for the original owner with registration, 20 years without it
- On the 987M, Bryant's Red Shield 10-year unit replacement warranty, which applies to heat exchanger failure only
Terms change, so read the current certificate at install. We handle registration as part of our install paperwork, and our own 2-year labor warranty on installs sits on top of Bryant's parts coverage.
Rebates, and which Bryant we'd pick
Utility furnace rebates are tied to efficiency. CenterPoint Energy's heating rebates require equipment listed with verified AFUE and let you use the dealer of your choice, and Xcel Energy runs its own gas furnace rebates. Check the current program page before you buy. Our Xcel and CenterPoint rebate guide lists where to look. The federal 25C credit ended for equipment placed in service after December 31, 2025, so don't count on it.
How we'd usually match them to houses:
- Legacy 80% (800S family): rentals, or homes where condensing venting can't be routed
- Legacy condensing (912S, 916S): tight budgets in homes that can vent through PVC
- Preferred two-stage (926T): most Minnesota ramblers, split-levels and two-stories on natural gas
- Evolution 987M: larger two-stories, zoned systems, or homes pairing the furnace with a Bryant heat pump
If you're still choosing between brands, our guide to the best furnace brands for Minnesota winters puts Bryant next to the others.
How much does a Bryant Evolution or Legacy furnace cost?
Our installed furnace range is $4,500–$9,500: roughly $4,500–$6,000 for 80% furnaces and $6,500–$9,500 for 96–98% models. A Legacy 800S sits toward the low end and an Evolution 987M toward the top, with venting, returns and the thermostat moving the rest. We size every replacement with a Manual J load calculation, not by copying the old nameplate. In older city houses, venting and returns often drive the price; our page on furnace replacement in Minneapolis explains why.
Questions to ask on any Bryant quote
- Which exact model is quoted, and was it sized with a load calculation?
- What venting changes are included: PVC routing, the condensate drain, and a liner for the water heater if it's left in the chimney?
- Which thermostat is included, and does it keep the communicating features on an Evolution?
- Who registers the warranty within Bryant's 90-day window?
- Does the rebate you're counting on require an AHRI listing or a registered contractor?

Call 612-429-3465, any day from 7am to 9pm.
Questions
Is a Legacy furnace a bad furnace?
No. Legacy is Bryant's simplest line, not a weak one. A single-stage furnace with a fixed-speed blower has fewer parts to fail and cheaper parts when they do. It runs at full fire every cycle, so it's louder and less even than a staged furnace, but it heats a Minnesota house fine when it's sized correctly.
Does an Evolution furnace need the Evolution thermostat?
To get the communicating features, such as Bryant's Perfect Heat and Perfect Humidity functions and stored fault history, it pairs with the Evolution Connex control. If you prefer a different smart thermostat, ask before you buy, because some features depend on Bryant's own control.
Will an Evolution furnace cut my gas bill?
Compared with an old 80% furnace, yes, because any condensing furnace wastes less fuel up the flue. Compared with a Legacy 916S, which Bryant rates up to 97% AFUE, the difference in rated efficiency is small. Buy the Evolution for comfort and quiet, and expect gas savings to come mainly from moving off an 80% furnace.
Is Bryant the same as Carrier?
Not quite. Bryant and Carrier share a parent company, Carrier Global, and much of their engineering, but they use different model names and sell through different dealer networks. Bryant's Evolution, Preferred and Legacy line up roughly with Carrier's Infinity, Performance and Comfort. Many repair parts cross over between Bryant and Carrier furnaces of the same generation, which helps when something breaks in January.
