Concord Furnaces, Air Conditioners & Heat Pumps

Voomi Supply carries Concord gas furnaces, split air conditioners, and heat pumps, from base 80% AFUE single-stage furnaces to 97% AFUE two-stage models, paired with air conditioners and heat pumps rated up to 16 SEER. Concord is manufactured by Allied Air Enterprises, a Carrier family company that also builds the Ducane brand, and is sold primarily through wholesale HVAC distributors rather than retail stores. Every order ships with Voomi's 30-day return policy and free help matching a system to your home.

Furnace Efficiency Tiers: 80%, 95%, 96%, and 97% AFUE

Concord furnaces are built across four efficiency tiers, and the right one depends on climate, budget, and how long you plan to stay in the home:

AFUE Rating

Stage Type

Best For

80%

Single-stage, constant torque

Lower upfront cost, moderate climates, replacement budgets

95%

Single-stage, constant torque

Higher efficiency without the cost of a modulating system

96%

Single-stage, constant torque

Colder climates wanting near-top efficiency at a single-stage price

97%

Two-stage, modulating (G2E/G2V)

Maximum efficiency and even heat distribution in cold climates

 

What "Constant Torque" Means on a Concord Furnace

Most Concord furnaces in this collection use a constant torque blower motor, which automatically adjusts speed to maintain steady airflow as filters load up or duct static pressure changes. That's different from the standard PSC motors used in older or base-tier furnaces, which run at a fixed speed regardless of system conditions. A constant torque motor uses less electricity than a PSC motor and delivers steadier comfort, without the higher cost of a fully variable-speed ECM motor.

Concord Air Conditioners and Heat Pumps

Concord split air conditioners and heat pumps in this collection run on R-410A refrigerant and are rated up to 16 SEER, including the Legacy series air conditioners and 4HP16L heat pumps. A Concord air conditioner or heat pump is built to pair with a matching Concord furnace or air handler cabinet, so check tonnage and cabinet width together rather than choosing the outdoor and indoor units separately. For heating-only or cooling-only equipment outside this collection, see our full Residential Heating Systems and Heat Pump Systems collections.

Choosing the Right Orientation

Concord furnaces are sold in upflow, downflow, and horizontal configurations, and the wrong orientation won't fit your existing ductwork or venting even if the tonnage and efficiency are correct. Upflow furnaces pull air in from the bottom and push heated air out the top, typical for basement installations feeding ductwork above. Downflow furnaces do the reverse, common in closet installations feeding ductwork below a home built on a slab. Horizontal furnaces lay on their side for attic or crawlspace installations. Check your existing furnace's orientation before ordering a replacement.

Frequently Asked Questions

Concord is manufactured by Allied Air Enterprises, part of the Carrier family of companies, which also produces the Ducane brand. Concord equipment is sold through wholesale HVAC distributors rather than big-box retail.

The AFUE percentage is how much fuel the furnace converts to usable heat, so a 97% AFUE furnace wastes less energy than an 80% model. Higher-AFUE furnaces cost more upfront but lower monthly heating bills, and the payback period depends on your climate and local gas prices.

A constant torque blower motor automatically adjusts its speed to maintain steady airflow as filters load up or duct conditions change, using less electricity than a fixed-speed PSC motor while costing less than a fully variable-speed ECM motor.

Yes, Concord outdoor units are designed to pair with matching Concord furnaces and air handlers. Confirm tonnage and cabinet width match between the indoor and outdoor units before ordering, since a mismatch reduces efficiency even when both parts are Concord-branded.

Current Concord air conditioners and heat pumps in this collection run on R-410A refrigerant. Check the rating plate on any existing outdoor unit before ordering a replacement to confirm refrigerant type.

Check your existing furnace's airflow direction and installation location. A basement furnace feeding ductwork above is typically upflow, a closet furnace on a slab feeding ductwork below is typically downflow, and an attic or crawlspace furnace lying on its side is horizontal.

Warranty coverage varies by model and is listed on each product page. Registering the system after installation is typically required to activate the full manufacturer warranty period.
