1.5 Ton 14 SEER 80% AFUE 60,000 BTU Goodman Gas Furnace and Air Conditioner System - Upflow Review 2026

// Bottom Line

This Goodman system works well for budget-conscious homeowners upgrading from older single-stage equipment in moderate climates. The dual-stage burner and high-efficiency blower motor keep operating costs reasonable while the upflow configuration fits most basement and closet installations.

Review

Goodman's 1.5-ton upflow gas furnace and air conditioner system positions itself as a practical mid-market solution for homeowners upgrading aging equipment. Manufactured as SKU LS38343850 and replacing the GSX16S181 model, this unit combines proven furnace technology with contemporary cooling efficiency. At zero dollars, pricing appears promotional or incomplete, but the specification sheet reveals a straightforward, no-frills approach to residential HVAC that prioritizes dependability over cutting-edge features.

The heating side delivers 60,000 BTU across two burner stages, allowing partial-fire operation on mild days to reduce energy waste. The 80% AFUE rating means relatively standard heating efficiency by current standards, though acceptable for retrofit applications. Cooling capacity reaches 18,000 BTU with a 16 SEER rating and R410A refrigerant compatibility. The scroll compressor with single-stage operation runs at 71.5 dB, louder than variable-capacity competitors but typical for fixed-stage units. Multi-speed blower capability up to 1200 CFM provides good air handler flexibility.

Pros & Cons

Pros

Two-stage burner system reduces short-cycling and improves comfort on milder days
High-efficiency multi-speed blower motor with 1200 CFM maximum capacity optimizes air distribution
Energy Star certified with 16 SEER rating on AC side, reducing summer cooling costs
Compact dimensions at 22 inches tall fit tight installation spaces
10-year warranty with online registration provides decent coverage security

Cons

80% AFUE is standard but not high-efficiency, meaning 20% of fuel energy is lost up the flue
Single-stage condenser limits cooling modulation compared to two-stage models
71.5 dB noise level runs slightly loud at full capacity during startup cycles

Who Should Buy

Best For

Homeowners in zones 4-6 replacing 15+ year old systems who want reliable performance without premium pricing. This unit suits split-system applications where upflow mounting is required and existing ductwork can accommodate 1200 CFM airflow.

Consider Alternatives If

Anyone needing cold-climate performance should look at 90%+ AFUE units, and those seeking variable-capacity cooling should consider two-stage condenser models instead.

Installation

Upflow configuration suits basement and utility closet mounting in single-story homes. Unit requires 208/230V single-phase 60Hz electrical service with 12.4 to 20-amp breaker sizing. Metal flue exhaust connection needed for furnace venting. Standard A-coil design integrates with matching condenser and indoor coil. Installation fits standard cut-in dimensions, though field technicians should verify ductwork supports 1200 CFM airflow without excessive resistance.

Warranty & Reliability

Goodman backs this system with a 10-year parts warranty upon online registration. This mid-tier coverage protects against compressor, heat exchanger, and control board failures. Registration is mandatory to activate coverage, so buyers must complete paperwork promptly. No labor coverage included, meaning technician visit costs fall to the homeowner, a common limitation in this price tier.

Frequently Asked Questions

Is this a true 1.5-ton system, or does the 2.5-ton cooling rating matter? +

The spec sheet shows conflicting tonnage data, listing both 1.5 ton in the product title and 2.5 ton under tonnage. The 18,000 BTU cooling capacity equals 1.5 tons exactly. Verify with the seller before purchase, as this discrepancy suggests spec sheet errors needing clarification from Goodman directly.

Can this furnace work with my existing downflow ductwork and closet space? +

This unit is rated for upflow or horizontal configuration according to the airflow direction specification. Downflow applications require a downflow-capable model. Dimensions of 22 inches tall by 17.5 inches wide by 21 inches deep fit most closets, but measure your space before ordering.

What does the 80% AFUE efficiency rating mean for my heating bills? +

Eighty percent AFUE means 80 cents of every heating dollar converts to usable heat, with 20 cents lost through flue venting. Modern high-efficiency units reach 95% AFUE, potentially saving 15% on annual heating costs, though initial investment is higher.

How does this single-stage condenser compare to two-stage models? +

Single-stage condensers run at full capacity or off, consuming maximum power even on cool days. Two-stage models modulate output, reducing electricity use during mild weather. Two-stage systems cost more upfront but may lower cooling costs 10-15% over five years.

Will online registration for the 10-year warranty actually work, or is it a hassle? +

Goodman's online registration process is straightforward and takes five minutes. Registration confirms warranty activation immediately. Without registration, no warranty protection applies, so complete it before installation work begins.
