4 Ton 13 SEER 96% AFUE 120,000 BTU Goodman Gas Furnace and Air Conditioner System - Upflow Review 2026

// Bottom Line

This ACiQ system excels for homeowners in mixed heating and cooling climates who want strong efficiency without premium pricing. The 96% AFUE furnace and 13 SEER condenser deliver real energy savings, especially for gas-heated regions where winter heating dominates utility bills.

Review

The ACiQ 4-ton system positions itself as a balanced offering in the mid-market HVAC space. This upflow configuration combines a high-efficiency furnace with a standard-efficiency air conditioner, making it particularly strong for regions where winter heating drives energy costs. The unit ships with a 10-year warranty when registered online, and ACiQ's brand reputation centers on reliability and contractor support. At this price point, the system targets budget-conscious homeowners and value-focused contractors who need dependable performance without premium features.

Real-world performance depends heavily on furnace usage. The 120,000 BTU furnace operates at 96% AFUE, meaning 96 cents of every dollar spent on gas converts to usable heat. The cooling side delivers 48,000 BTU at 13 SEER, which ranks solid but not exceptional in today's market. The two-stage burner modulates between high and low fire, improving comfort during mild heating days. Variable-speed ECM motor provides 2000 CFM maximum airflow and reduces standby electricity draw compared to fixed-speed blowers found on economy units.

Pros & Cons

Pros

96% AFUE furnace efficiency captures nearly all fuel energy, reducing heating costs significantly compared to 80-90% models
13 SEER cooling efficiency meets Energy Star standards and qualifies for many utility rebates
Dual fuel capability with natural gas and propane options provides flexibility for different installations
Two-stage burner modulates heat output for better comfort and efficiency than single-stage alternatives
Variable-speed ECM blower motor adjusts airflow to match load, reducing electricity consumption and noise

Cons

Single-stage compressor in the 5-ton condenser means less modulation and efficiency in partial-load cooling scenarios
76 dB noise level is louder than some premium competitors, potentially noticeable during operation in quiet neighborhoods
5-ton cooling capacity creates a mismatch if paired with a 4-ton load requirement, risking oversizing inefficiencies

Who Should Buy

Best For

Homeowners in northern and transitional climates where heating runtime exceeds cooling will see strong ROI from the 96% AFUE furnace. Contractors valuing straightforward installation and reliable performance on mixed-duty applications will appreciate the ECM motor and proven ACiQ platform.

Consider Alternatives If

Buyers in hot climates where cooling dominates should prioritize higher SEER ratings, and those seeking ultra-quiet operation should evaluate premium models with variable-speed compressors.

Installation

This upflow unit requires proper ducting sized for 2000 CFM maximum airflow. Suction line insulation must be 1/2 inch thick over 50 feet of refrigerant piping using 1 1/8 inch tubing. Liquid line uses 3/8 inch with sweat fittings. Electrical requires 26.3 to 45 amp breaker from a 115V single-phase panel. PVC or plastic exhaust flue is mandatory. Most installations take 4 to 6 hours for experienced technicians.

Warranty & Reliability

Ten-year parts coverage applies when you register the system online within 30 days of installation. This warranty covers compressor, blower motor, and heat exchanger defects but excludes maintenance neglect and improper installation. Registration is free and takes five minutes online, making this a realistic protection for most buyers willing to follow through on paperwork.

Frequently Asked Questions

Why does the spec sheet list 4 ton but also say 5 ton tonnage? +

This product shows conflicting data, likely a manufacturer error. The 48,000 BTU cooling capacity equals 4 tons, while the tonnage field shows 5 ton. Verify with the seller or AHRI certificate 7368842 before purchase to confirm actual cooling capacity and ensure proper system sizing for your home.

Can I install this in a downflow configuration? +

The spec sheet lists configuration as upflow/downflow, suggesting downflow capability exists. However, the primary listing emphasizes upflow design. Contact the manufacturer or your installer to confirm whether downflow modification requires different ductwork or components before committing to that orientation.

How much will this system reduce my heating costs compared to an 80% AFUE furnace? +

At 96% AFUE versus 80%, you gain 16 percentage points of efficiency. On a 100,000 BTU heating load, the 96% furnace uses roughly 20% less gas annually. Actual savings depend on local gas prices and your climate's heating degree days, but northern homeowners typically see 15 to 25 percent yearly heating cost reduction.

How does 13 SEER compare to modern air conditioner efficiency standards? +

13 SEER meets Energy Star minimums but ranks below current regional standards in hot climates, where 15 to 16 SEER is common. For moderate cooling demand areas, 13 SEER delivers good efficiency without premium cost. If cooling runtime is significant in your region, consider higher SEER alternatives for faster payback on efficiency upgrades.

What does the 10-year warranty actually cover? +

Parts coverage includes compressor, blower motor, heat exchanger, and refrigerant charge for defects. Labor is typically not covered. Registration within 30 days is mandatory. Read the full warranty document before installation to confirm coverage limits and claim procedures with your specific retailer.
