// Bottom Line
This Goodman system delivers solid performance for homeowners in moderate climates who prioritize heating efficiency over cooling power. The 96% AFUE furnace and Energy Star rated air conditioner make it a practical choice for contractors seeking dependable, cost-effective equipment at competitive pricing.

Review

Goodman's horizontal gas furnace and air conditioner combo addresses a specific market segment, homeowners seeking to prioritize heating efficiency without overpaying for premium cooling capacity. At $3,136, this 120,000 BTU system carries competitive pricing for dual-stage equipment and includes Energy Star certification. The horizontal A-coil configuration fits tight attic or basement installations where traditional vertical units won't work, making it practical for retrofit applications and new construction.

The heating side is this system's strength, delivering 96% AFUE efficiency with a two-stage burner that modulates for partial-load operation. On cooling, the two-stage scroll compressor achieves 18 SEER1 on the condenser, though the 47,000 BTU capacity undercuts typical 4-ton expectations. The variable-speed ECM blower handles up to 2,000 CFM and adjusts airflow based on demand, improving temperature consistency. At 72 decibels during operation, noise levels remain acceptable for residential settings.

Pros & Cons

Pros

  • 96% AFUE furnace efficiency translates to lower heating bills in northern climates
  • Two-stage compressor and burner system reduces energy consumption and noise at partial load
  • Energy Star certified with 18 SEER1 cooling rating on condenser unit
  • Variable-speed ECM blower motor offers better temperature control and humidity management
  • 10-year warranty with online registration provides solid long-term protection
  • Plastic PVC venting reduces installation costs compared to metal exhaust requirements

Cons

  • 47,000 BTU cooling capacity falls short for true 4-ton cooling demand in hot climates
  • 72 dB noise level at full operation may be noticeable in quiet residential settings
  • Requires licensed technician for gas line installation, adding labor costs to project

Who Should Buy

Best For

Contractors and homeowners in northern or moderate climates where heating demand exceeds cooling demand will appreciate the high furnace efficiency. This system is ideal for mixed-climate applications where the 120,000 BTU heating output justifies the investment and the modest cooling capacity meets seasonal needs.

Consider Alternatives If

Skip this unit if you live in hot climates requiring consistent high-capacity cooling or if you need true 4-ton cooling performance. The 47,000 BTU output won't handle peak summer cooling demands effectively.

Installation

This system requires a trained, licensed technician to connect gas lines safely and vent the flue through plastic PVC pipe. The 158-pound weight and horizontal configuration fit challenging spaces but demand proper structural support. Electrical requirements are modest, running on 115V single-phase with breaker sizing between 29.3 and 50 amps. Installation should include AHRI certification verification using the included certificate number 7368845 for warranty validation.

Warranty & Reliability

Goodman backs this system with a 10-year parts and labor warranty, activated through online registration. This coverage is solid for residential use but standard across mid-tier manufacturers. Extended warranties may be available through dealers. Registration ensures claims processing and proof of purchase, so complete it immediately after installation.

Frequently Asked Questions

Why does the spec sheet list both 4 ton and 5 ton ratings? +
The condenser unit is rated at 5 tons, but the furnace and system are marketed as 4 ton. The 47,000 BTU cooling output matches a true 4-ton capacity (12,000 BTU per ton). This mismatch can occur when units are matched for moderate climates where heating demand drives sizing decisions rather than peak cooling load.
Can I install this myself or do I need a professional? +
You must hire a licensed HVAC technician. The safety warning explicitly requires trained installation for gas connections and flue venting. Improper gas line connections or venting can cause death or injury. Many jurisdictions legally require licensure for installation, so verify local codes before proceeding.
How does the 18 SEER1 compare to modern standards? +
SEER1 of 18 is good but not exceptional for 2024 standards. Premium systems exceed 20 SEER1. However, this rating reflects real-world conditions better than older SEER metrics. For moderate cooling climates, 18 SEER1 delivers adequate efficiency at reasonable cost.
Is this system right if I need 4 tons of actual cooling capacity? +
No. The 47,000 BTU cooling output equals approximately 3.9 tons of capacity. If your load calculation requires true 4-ton cooling for summer comfort, choose equipment rated at 48,000 BTU or higher to avoid undersizing issues and comfort complaints.
What does the 10-year warranty actually cover? +
Goodman covers parts and labor defects for 10 years when registered online. Coverage applies to manufacturing defects only, not neglect, improper installation, or normal wear. Review the full warranty document included in resources before assuming specific coverage limits apply to your situation.
