4 Ton 13 SEER 96% AFUE 80,000 BTU Goodman Gas Furnace and Air Conditioner System - Upflow Review 2026

// Bottom Line

This ACiQ combo system excels for homeowners upgrading from older two-piece units who want high heating efficiency without replacing their entire infrastructure. The 96% AFUE furnace and 13 SEER air conditioner handle most residential climates well, especially in moderate zones where extreme seasonal demands are less critical.

Review

The ACiQ ACIQ-48-EHPD-UPG represents a straightforward, competent solution for residential HVAC replacement. This 4-ton upflow system combines a gas furnace and air conditioner in one package, eliminating the complexity of sourcing matched components separately. It's positioned as a mid-tier option, lacking premium features like inverter-driven compressors but offering solid fundamental performance at reasonable cost. ACiQ manufacturers equipment under parent company Goodman, ensuring manufacturing standards and supply chain reliability that contractors depend on.

Performance numbers tell the real story here. The furnace delivers 80,000 BTU output at 96% AFUE, meaning 96 cents of every natural gas dollar converts to usable heat, the legal maximum for non-condensing units. The air conditioner provides 48,000 BTU cooling capacity with 13 SEER1 efficiency using R454B refrigerant. The variable-speed ECM blower motor runs from 0 to 1600 CFM, matching airflow to actual heating and cooling demands rather than running full blast constantly. Energy Star certification confirms independent verification of these efficiency claims.

Pros & Cons

Pros

96% AFUE furnace efficiency means lower winter heating bills and reduced natural gas waste
13 SEER cooling with R454B refrigerant meets current EPA standards without retrofit hassle
Variable speed ECM blower motor adjusts airflow from 0 to 1600 CFM for comfort and efficiency
PVC/plastic flue compatibility simplifies venting in many existing installations
Two-stage burner reduces temperature swings and improves comfort over single-stage models
Energy Star certified system qualifies for utility rebates in many regions

Cons

Single-stage compressor in the air conditioner limits part-load efficiency compared to variable capacity units
76 dB noise level is audible during operation, noticeable in quiet homes
5-ton capacity mismatches the stated 4-ton rating, creating confusion during system sizing

Who Should Buy

Best For

Contractors installing matched furnace-condenser pairs for residential replacements in climate zones 3-5, and homeowners in moderate climates prioritizing heating efficiency without premium cooling capabilities. This system works best where heating season costs exceed cooling costs.

Consider Alternatives If

Anyone in hot climates needing multi-stage cooling, homes with very tight noise budgets, or builders planning premium installations where variable-capacity compressors justify higher costs.

Installation

The upflow configuration and compact 30x21x21 inch footprint fit standard utility closets and basement installations. PVC/plastic flue requirement simplifies venting compared to metal flue-dependent systems. Electrical demands are moderate, requiring 26.3 to 45 amp breaker sizing on standard 115V 1-phase 60Hz service. Sweat valve connections use standard 3/8 inch liquid and 1 1/8 inch suction lines with 1/2 inch insulation included for 50 feet of lineset.

Warranty & Reliability

Ten-year coverage applies when registered online within 30 days of installation, a standard practice across the industry. This warranty covers compressor, coil, and furnace heat exchanger failures. It does not cover routine maintenance, refrigerant recharges, or damage from improper installation. Online registration is free and takes five minutes, making this warranty accessible to both contractors and DIY-inclined homeowners.

Frequently Asked Questions

Why does the spec sheet list 5-ton capacity when this is marketed as a 4-ton system? +

This appears to be a data entry error in the specifications. The model designation and cooling output of 48,000 BTU confirm this is a 4-ton unit, not 5-ton. Verify tonnage independently before ordering to ensure proper system sizing for your load calculation.

Can I install this myself, or do I need a licensed contractor? +

While technically possible for experienced DIYers, refrigerant handling and gas connections legally require EPA certification and often state licensing. Most states mandate professional installation for warranty validity. Budget for professional installation costs of $1,500 to $3,000 depending on your region and existing ductwork condition.

How does 13 SEER compare to newer 14-16 SEER systems I'm seeing advertised? +

13 SEER meets current minimum federal standards and saves about 30% versus 10 SEER equipment. Higher SEER ratings (14-16) require variable-capacity compressors and cost $1,500 to $3,000 more. In moderate climates, 13 SEER returns adequate efficiency without premium pricing.

This system uses R454B refrigerant. Will older equipment work with this? +

No. R454B is incompatible with systems designed for R410A or R22. If replacing a condenser only, the furnace and coil must be compatible with R454B. This matched pair ensures proper operation without cross-refrigerant issues.

What happens if something breaks after the 10-year warranty expires? +

Repairs are out-of-pocket. Compressor replacement typically costs $600 to $1,500. Extended warranties offered at purchase can extend coverage, but usually cost 15 to 20% of system price and require careful terms review.
