// Bottom Line
This combination unit works best for homeowners replacing older split systems who want both heating and cooling efficiency without buying separate units. The 97% AFUE furnace and 13 SEER condenser deliver solid year-round performance at a competitive price point.

Review

ACiQ's 5-ton system combines a gas furnace and air conditioner in downflow configuration, making it a practical replacement for contractors working with Goodman legacy equipment. This unit replaces six previous Goodman models (GSX130603 through GSX130614), indicating solid manufacturer support for existing installations. The downflow design suits basements and crawl spaces where horizontal or upflow placement isn't feasible. At 120 pounds and 30 inches tall, it handles standard equipment pads without reinforcement concerns.

The 97% AFUE furnace with 100,000 BTU output and modulating burner delivers impressive winter efficiency, while the air conditioner's 60,000 BTU capacity and 13 SEER rating meet Energy Star requirements. The variable-speed ECM blower reaches 2,000 CFM maximum but runs at lower speeds during light-load conditions, reducing energy waste. R454B refrigerant meets current EPA standards. Electrical requirements of 32.8 to 45 amps are typical for equipment this size and compatible with most residential panels.

Pros & Cons

Pros

  • 97% AFUE furnace efficiency reduces heating costs significantly compared to 80-90% alternatives
  • 13 SEER air conditioner meets Energy Star standards and qualifies for many utility rebates
  • Modulating gas burner adjusts heating output automatically, improving comfort and reducing waste
  • Variable-speed ECM blower motor handles up to 2,000 CFM and adapts to actual heating and cooling demand
  • 10-year warranty with online registration provides solid protection for both components

Cons

  • 77 dB noise level runs louder than some competitors during compressor operation
  • Single-stage air conditioner cannot modulate cooling capacity like higher-end two-stage units
  • Requires 32.8 to 45 amp breaker, so older electrical panels may need upgrade

Who Should Buy

Best For

Contractors and homeowners replacing older Goodman furnace-AC combinations will appreciate the compatibility and straightforward installation. Budget-conscious buyers upgrading from 80% AFUE systems will see meaningful energy savings over 15-20 years of operation.

Consider Alternatives If

Those seeking ultra-quiet operation or maximum modulation capability should explore 14-16 SEER two-stage units, which command higher prices but deliver quieter, more efficient cooling.

Installation

Installation uses sweat valve connections with 3/8-inch liquid and 7/8-inch suction lines, requiring basic HVAC soldering skills. Pre-insulated suction line with 3/8-inch thickness reduces job-site insulation work. PVC or plastic exhaust flue compatibility suits homes with modern venting. Most experienced technicians complete installation in one day, though first-time installers should budget 1.5 days for careful setup.

Warranty & Reliability

The 10-year warranty covers manufacturing defects across both furnace and air conditioner components when registered online. This protection rivals competitors at similar price points. Coverage extends parts and labor through participating dealers, though homeowners should confirm local service availability before purchase. Warranty registration typically completes during installation.

Frequently Asked Questions

Can this unit replace my older Goodman system? +
Yes, it directly replaces six legacy Goodman models (GSX130603, GSX130604, GSX130605, GSX130611, GSX130613, GSX130614). Verify your existing model number against this list before ordering. Refrigerant lines and electrical connections match standard Goodman configurations, simplifying retrofit installation.
Will this system fit my basement installation? +
The downflow/horizontal design works well for basements. At 30 inches tall and 21 inches wide and deep, it fits standard equipment pads. Confirm your space accommodates 30-foot suction line routing with proper insulation. Plastic exhaust venting simplifies installation compared to traditional metal flue pipe.
How much will this reduce my heating and cooling bills? +
Upgrading from an 80% AFUE furnace saves roughly 17% on heating costs. The 13 SEER air conditioner saves approximately 25-30% versus 10 SEER units. Actual savings depend on climate, usage patterns, and thermostat settings. Calculate your specific payback period using local energy rates.
Is 13 SEER competitive with what else is available? +
13 SEER meets Energy Star standards and qualifies for utility rebates, but 14-16 SEER two-stage units offer better efficiency. This unit represents solid mid-range performance at entry-level pricing. Choose it for budget-conscious upgrades, not for maximum long-term efficiency gains.
What does the 10-year warranty actually cover? +
The warranty covers parts and labor defects on both furnace and air conditioner when you register online. Coverage typically extends through the product's first decade. Verify your installer participates in Goodman's service network before purchase to ensure local claim support.
