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

// Bottom Line

This Goodman 2.5 ton system works best for homeowners upgrading from older equipment who want reliable heating and cooling without premium pricing. The 80% AFUE furnace and 13 SEER air conditioner strike a practical balance between efficiency and affordability for moderate climates.

Review

The Goodman 2.5 ton upflow system is a straightforward choice for homeowners replacing aging HVAC equipment without chasing premium efficiency ratings. SKU LS38343850 combines gas heating and air conditioning in one matched pair, simplifying installation for contractors. Goodman's reputation for durability makes this configuration popular among HVAC shops managing cost-sensitive residential replacements where performance matters more than cutting-edge specifications.

Heating output reaches 80,000 BTU with a two-stage burner and multi-speed motor delivering up to 1200 CFM, while cooling capacity provides 30,000 BTU (2.5 tons) at 13 SEER. The 80% AFUE furnace efficiency is respectable for non-condensing models, though it runs hotter than 90%+ condensing alternatives. Reciprocating compressor with R410A or R22 compatibility and single-stage condenser design keeps complexity and cost reasonable for straightforward installations.

Pros & Cons

Pros

Two-stage burner with multi-speed blower delivers flexible heating from 80,000 BTU capacity, reducing short cycling and improving comfort
13 SEER cooling efficiency matches mid-range market standards for reasonable operating costs without high upfront investment
80% AFUE furnace efficiency is adequate for most residential applications and avoids premium high-efficiency equipment costs
Multi-speed blower motor with 1200 CFM maximum capacity enables better air distribution across typical 2-3 ton homes
10-year warranty with online registration provides solid coverage for furnace and coil components, standard for this price tier

Cons

80% AFUE and 13 SEER are both one generation behind current high-efficiency standards, meaning higher operating costs over 15-year lifespan
Single-stage air conditioning condenser cannot modulate capacity on mild days, reducing efficiency compared to two-stage units
73 dB noise level runs slightly louder than premium models, which can be noticeable in quiet residential settings

Who Should Buy

Best For

Contractors installing replacement systems for budget-conscious homeowners and HVAC shops needing reliable baseline equipment for mid-sized residential applications. This system is ideal when upfront cost matters more than achieving maximum long-term efficiency savings.

Consider Alternatives If

Homeowners in cold climates needing high-efficiency heat, those planning to stay 20+ years seeking lower utility bills, or anyone prioritizing ENERGY STAR certification and modulating capacity should explore 95% AFUE furnaces and 16+ SEER air conditioners instead.

Installation

This upflow system requires metal exhaust flue, 208/230V single-phase 60Hz power, and 16.7 to 25 amp breaker sizing. Dimensions of 22 inches height by 17.5 inches width by 21 inches depth fit standard utility closets or basement locations. The 3/8 inch liquid line and 3/4 inch suction line with 50-foot maximum run length accommodate typical residential layouts with standard sweat valve connections.

Warranty & Reliability

Ten-year full warranty on furnace and coil components with online registration provides solid coverage for manufacturing defects and component failure. This warranty period is standard for mid-tier residential equipment and covers both heating and cooling sections, reducing out-of-pocket risk during early years after installation.

Frequently Asked Questions

What's the actual heating capacity in BTU, and is it adequate for my home? +

This unit delivers 80,000 BTU of heating output, typically suitable for 1,500 to 2,200 square feet in moderate climates. Two-stage burner operation means it runs at partial capacity most of the time, reducing energy waste. For very cold climates or larger homes, consider larger tonnage systems or high-efficiency models with better part-load performance.

What electrical work is required during installation? +

This system needs 208/230V single-phase 60Hz power with a dedicated breaker sized between 16.7 and 25 amps. Most residential homes have compatible service. Your electrician should verify your panel capacity and install appropriate breaker before the HVAC contractor connects equipment to avoid startup issues.

How does 80% AFUE compare to newer furnaces, and what will operating costs look like? +

80% AFUE means 20% of fuel energy escapes through the exhaust, while modern 95%+ AFUE condensing furnaces retain more heat. Over 20 years, a 95% AFUE unit saves $2,000 to $4,000 in heating costs depending on climate and gas prices. This system works best when upfront cost matters more than long-term savings.

Is 13 SEER cooling efficiency competitive, and should I wait for higher SEER models? +

13 SEER represents mid-2010s technology and is competent but not premium. Current ENERGY STAR units hit 16+ SEER with lower operating costs. If you plan 15+ years of ownership in a warm climate, higher SEER models justify higher upfront investment through utility bill reduction. Otherwise, this tier balances performance and affordability.

What does the 10-year warranty actually cover, and what isn't included? +

Coverage includes furnace heat exchanger, compressor, and evaporator coil defects with online registration. Labor, refrigerant, ductwork, and normal maintenance are not covered. Most failures occur after five years, so this warranty protects against early manufacturing defects rather than long-term repairs.
