4 Ton 17 SEER 97% AFUE 120,000 BTU Goodman Gas Furnace and Air Conditioner System - Horizontal Review 2026

// Bottom Line

This Goodman system excels for homeowners upgrading to a high-efficiency horizontal setup in attics or crawlspaces where PVC venting is feasible. The 97% AFUE furnace and variable-speed blower make it cost-effective over time, though upfront pricing and the tonnage mismatch require careful planning.

Review

The Goodman CHPF4860D6 is a horizontal split-system furnace and air conditioner designed for retrofit and new construction projects where space is limited. Positioned as a mid-tier residential option, it balances efficiency gains with reasonable cost, making it appealing to contractors seeking reliable equipment without premium pricing. The system earned AHRI certification number 7424268 and carries Energy Star qualification, signals of compliance with modern efficiency standards.

Performance metrics highlight the furnace's 97% AFUE rating, which converts nearly all natural gas or propane into usable heat. Cooling capacity reaches 47,000 BTU with an 18 SEER2 rating, translating to roughly 18 dollars of cooling output per watt consumed. The modulating burner adjusts firing rates rather than cycling on and off, reducing temperature swings. Variable-speed ECM blower ranges to 2,000 CFM maximum, allowing the system to run efficiently at partial load during mild weather.

Pros & Cons

Pros

97% AFUE furnace efficiency reduces heating costs significantly compared to older systems
Modulating burner stages optimize fuel consumption and maintain consistent comfort
Variable-speed ECM blower delivers precise airflow control and quieter operation at partial load
18 SEER2 cooling efficiency qualifies for Energy Star and available rebates
10-year warranty with online registration provides solid protection for the investment

Cons

Tonnage mismatch: System rated as 5-ton cooling but specs show 4-ton 47,000 BTU capacity, creating confusion during sizing
Right-side flue location limits installation flexibility in some attic layouts
72 dB noise level is moderately loud for equipment running in occupied spaces

Who Should Buy

Best For

Homeowners replacing a furnace and AC unit in attic or horizontal crawlspace installations where PVC venting is available. This system works well for moderate climates where high-stage heating and two-stage cooling balance efficiency with comfort.

Consider Alternatives If

Those needing vertical upflow installations, customers in areas requiring metal chimney venting, or homes that genuinely need true 4-ton cooling capacity should verify tonnage specifications before committing.

Installation

Horizontal configuration suits attics and tight spaces; dimensions measure 24.5 inches tall by 26 inches wide by 21.125 inches deep. PVC venting requirement simplifies installation compared to metal chimneys and lowers material costs. Right-side flue placement restricts placement options in some layouts. Electrical demand ranges from 29.3 to 50 amps on 208/230V single-phase power. Sweat valve connections and 3/8 inch liquid line standard connections integrate with most existing copper piping.

Warranty & Reliability

Goodman provides a 10-year parts warranty when owners register the system online, a meaningful commitment for HVAC equipment. This coverage protects against component failures on the compressor, blower, and heat exchanger during the decade following installation. Registration is straightforward and extends protection beyond the baseline warranty, rewarding diligent homeowners and contractors.

Frequently Asked Questions

Why does the spec sheet list both 4-ton and 5-ton ratings? +

The unit model suggests 4-ton cooling capacity, but the tonnage field lists 5-ton. This discrepancy likely reflects the furnace's heating size or a catalog inconsistency. Always cross-reference the actual 47,000 BTU cooling output with your load calculation before purchasing to ensure proper sizing.

Can this system work with my existing R22 refrigerant lines? +

The system accepts both R410A and R22, offering flexibility during retrofit scenarios. However, using R22 in newer equipment carries environmental concerns and higher long-term costs. R410A is the recommended choice and aligns with current EPA standards and future regulations.

How much will this system reduce my heating bills? +

A 97% AFUE furnace consumes roughly 15 to 25 percent less fuel than typical 80% AFUE models, depending on climate and usage patterns. Savings vary regionally but homeowners in cold climates often recoup the investment within 5 to 7 years through reduced energy consumption.

Is this system quieter than standard single-speed models? +

The variable-speed ECM blower runs at lower speeds during partial load, significantly reducing noise compared to constant-speed motors. At 72 dB, it remains moderately loud during full-capacity operation, comparable to normal conversation volume, but quieter during milder weather.

What does the 10-year warranty actually cover? +

Goodman covers parts for a decade with online registration, protecting major components like the compressor and heat exchanger. Labor and refrigerant are typically excluded, so review your specific warranty document and installer agreements for complete coverage details.
