Review
The ACiQ 3 Ton 13 SEER horizontal system slots into Goodman's reliable mid-market lineup as a direct replacement for older GSX130362, GSX130363, and GSX130365 models. This 120,000 BTU furnace targets contractors and homeowners upgrading from 1980s-era equipment or installing new systems in space-constrained applications. The horizontal A-coil design makes it practical for attics, basements, and crawlspaces where traditional upflow units don't fit. ACiQ maintains the Goodman reputation for straightforward engineering and service-friendly design without the premium pricing of marquee brands.
Heating performance centers on the 96% AFUE rating with two-stage burner operation, meaning the system runs at 60% capacity during moderate outdoor temperatures and kicks to full 120,000 BTU output only in deep cold snaps. The variable-speed ECM blower motor runs quieter during low-demand periods and ramps to 2000 CFM maximum when needed. Cooling rates at 36,000 BTU with 13 SEER1 efficiency deliver adequate seasonal performance for moderate climates, though southern installers may want 14+ SEER units. The reciprocating compressor and single-stage condenser keep the design simple and maintainable.
Pros & Cons
Pros
- 96% AFUE heating efficiency significantly reduces winter fuel costs compared to 80% baseline systems
- Variable-speed ECM blower motor adjusts airflow up to 2000 CFM for better temperature control and lower runtime noise
- Two-stage burner allows modulating operation during milder weather, improving comfort and efficiency
- Horizontal configuration fits crawlspaces and attics where upflow isn't practical
- 120,000 BTU heating capacity covers most single-zone residential applications effectively
Cons
- 13 SEER cooling is good but not exceptional; mid-range systems offer 14-16 SEER for modest upgrades
- R454B refrigerant requires contractor certification, adding potential service costs
- 74 dBA decibel level runs slightly louder than premium variable-capacity units during peak operation
Who Should Buy
Best For
Homeowners replacing failed Goodman GSX130362 or GSX130363 units who want straightforward efficiency gains without paying for top-tier performance. Contractors installing horizontal systems in basements, attics, or mechanical closets where space constraints rule out vertical configurations.
Consider Alternatives If
Buyers in extremely hot climates seeking maximum cooling efficiency or those wanting ENERGY STAR certification should look at higher-SEER alternatives or premium brands.
Installation
Horizontal installation requires upright mounting in attics or parallel positioning in crawlspaces, demanding careful ductwork routing to the A-coil inlet. PVC exhaust venting simplifies flue termination through walls or roofs without masonry chimneys. The 120-pound unit needs 208-230V single-phase 60 Hz service with 19.1 to 30-amp breaker sizing. Suction lines require 3/8-inch insulation thickness and 30-foot maximum run lengths per R454B specifications. Proper condensate drainage is critical in horizontal mounting.
Warranty & Reliability
Ten-year parts and compressor warranty applies with online registration, covering manufacturing defects and component failures. This matches industry standard mid-tier coverage. The included Goodman evaporator coil warranty extends protection on the matched cooling side. Warranty does not cover installation errors, refrigerant losses, or lack of maintenance, so proper commissioning and annual servicing are essential.
