2.5 Ton 13 SEER 80% AFUE 80,000 BTU Goodman Gas Furnace and Air Conditioner System - Upflow Review 2026

// Bottom Line

This Goodman system makes sense for budget-conscious homeowners and contractors needing a straightforward replacement in existing upflow installations. At $2,053, you're getting respectable 80% AFUE heating and 13 SEER cooling without paying for premium efficiency tiers.

Review

The 2.5-ton Goodman system delivers straightforward heating and cooling without unnecessary frills. At $2,053, this unit sits in the practical sweet spot for replacement projects and new construction where budget matters. Online Supply positions this SKU LS38343850 as no-nonsense equipment backed by Goodman's manufacturing heritage. You're getting an upflow-capable furnace paired with an A-coil evaporator, making it compatible with most existing ductwork layouts.

Performance figures tell a realistic story. The 80% AFUE rating means 80 cents of every heating dollar actually heats your home, matching standard non-condensing furnaces. Cooling output hits 30,000 BTU with a 13 SEER rating, which represents solid mid-range efficiency. The variable-speed blower motor (2,000 CFM maximum) adjusts to your heating and cooling needs, unlike fixed-speed alternatives. Two-stage burner operation reduces short-cycling during shoulder seasons. R410A refrigerant keeps the system current with EPA standards.

Pros & Cons

Pros

Exceptional value at $2,053 for a complete 2.5-ton system with furnace and coil included
Variable-speed blower motor improves comfort and reduces runtime noise versus single-stage alternatives
80% AFUE is industry standard for non-condensing furnaces, meaning predictable heating performance
Two-stage burner allows lower heating output during mild weather, reducing cycling and energy waste
10-year warranty with online registration provides solid peace-of-mind coverage for parts

Cons

Not Energy Star certified, so it won't qualify for certain utility rebates available to higher-efficiency models
80,000 BTU heating capacity may require supplemental heat for colder climates below zone 5
Single-stage condenser compressor means no part-load cooling efficiency, unlike two-stage units

Who Should Buy

Best For

Homeowners in moderate climates (zones 5-8) replacing older furnaces want to minimize upfront costs without sacrificing reliability. Contractors installing systems in rental properties or cost-sensitive residential markets benefit from Goodman's reputation for durability at this price tier.

Consider Alternatives If

Skip this if you need Energy Star certification for rebates, live in very cold climates requiring 100,000+ BTU heating, or want premium efficiency ratings like 95% AFUE or 16+ SEER.

Installation

Upflow configuration fits standard furnace closets and basement installations in most homes. The unit measures 30 inches tall by 21 inches wide and deep, making it compact enough for tight spaces. You'll need 208/230V single-phase power with a 16.7 to 25-amp breaker. Metal exhaust flue is required for safe venting. Installation demands proper ductwork sizing and refrigerant line connections, tasks best left to licensed technicians.

Warranty & Reliability

The 10-year parts warranty applies when you register online after installation. This covers compressor, furnace heat exchanger, and evaporator coil defects. Real-world experience shows Goodman handles warranty claims straightforwardly. You'll need proof of professional installation to validate coverage. The warranty doesn't cover labor, so budget separately for service calls.

Frequently Asked Questions

Why is this unit cheaper than competitors with similar tonnage and SEER ratings? +

Goodman prioritizes manufacturing efficiency and straightforward features over premium materials. You're paying for honest performance, not marketing budget. Single-stage condenser and non-condensing furnace keep component costs low while maintaining reliability across millions of installed units.

Can this system work with my existing ductwork designed for a 3-ton unit? +

The 2.5-ton capacity fits 3-ton ductwork just fine, though you won't achieve full cooling output if ducts are significantly undersized. Maximum CFM of 2,000 suits most standard residential installations. Have a technician measure your ductwork to confirm compatibility before ordering.

How does 80% AFUE compare to high-efficiency furnaces I've heard about? +

80% AFUE is industry baseline for standard furnaces. Premium condensing units reach 95% AFUE but cost 50 to 70 percent more. The 15-point efficiency gap typically recovers its cost over 12 to 15 years in colder climates. This 80% unit suits moderate zones and budget-first decisions.

Should I choose this or a Carrier or Lennox system at a higher price point? +

Goodman and Carrier are owned by the same parent company, using identical compressors. Premium brands charge more for features you may not need. This system delivers equivalent cooling and heating for substantially less. The difference lies in trim, controls, and marketing rather than core performance.

What happens if something breaks after the warranty expires? +

Goodman parts remain affordable and widely available through HVAC suppliers. A typical compressor replacement runs $600 to $900 in labor and parts. Most contractors stock Goodman components, keeping repair turnaround fast and cost-effective compared to boutique brands.
