Review
The Goodman 2.5-ton horizontal system brings serious efficiency credentials to a package designed for tight installation spaces. With a 96% AFUE furnace and 16 SEER cooling coil, this unit hits the efficiency ceiling for mid-tier residential equipment. The horizontal A-coil configuration targets homeowners retrofitting attics or crawlspaces where standard upflow designs simply won't fit. Goodman's reputation for durability, backed by Cooling Comfort's 10-year warranty, makes this a credible choice for contractors seeking reliable dual-fuel solutions.
The furnace delivers 80,000 BTU heating output across two modulating burner stages, allowing the system to ramp down in milder weather rather than cycling on and off at full capacity. The air conditioning side produces 29,000 BTU cooling (technically 2.5-ton equivalent), paired with a scroll compressor known for smooth, quiet operation. Variable-speed ECM blower technology adjusts airflow between 0-1600 CFM based on demand, reducing energy waste and improving comfort. Energy Star certification confirms this unit meets EPA efficiency thresholds. Electrical demand runs 17.1-25 amps at 115V, fitting standard residential panels without upgrades in most cases.
Pros & Cons
Pros
- 96% AFUE furnace efficiency exceeds most single-stage competitors, reducing heating costs by 10-15% annually
- 16 SEER cooling rating delivers ENERGY STAR certification with meaningful efficiency gains over older 13-14 SEER units
- Horizontal A-coil configuration fits tight spaces where standard upflow units won't work
- Variable-speed ECM blower motor adjusts automatically for quiet operation and better dehumidification
- Two-stage burner provides modulating heat output for improved comfort and reduced cycling
- Scroll compressor is known for reliability with fewer moving parts than reciprocating designs
Cons
- Specs list both 2.5-ton and 3.5-ton tonnage with conflicting BTU ratings (29,000 cooling vs 80,000 heating), creating confusion on actual system capacity
- Single-stage air conditioning lacks variable capacity found in inverter-driven competitors, limiting part-load efficiency
- 71.5 dB noise level is moderately loud for a residential condenser, noticeable during operation
- Requires plastic PVC exhaust flue, limiting installation flexibility in some older homes with metal flues
- 10-year warranty requires online registration, which some contractors find burdensome for customer follow-up
Who Should Buy
Best For
Contractors and homeowners upgrading attic or crawlspace units in moderate climates who need both heating and cooling in a compact footprint. This system works especially well for homes with existing natural gas or propane lines seeking to replace 10-15 year old equipment.
Consider Alternatives If
Buyers in extreme climates needing maximum dehumidification or those with limited electrical service, as the 17-25 amp requirement may strain older panels.
Installation
Horizontal orientation requires careful mounting in attic or crawlspace, with proper condensate drainage toward sloped lines. The 3/8 inch liquid line and 7/8 inch suction line accept standard refrigerant connections. PVC exhaust flue (plastic only, no metal) must slope properly for condensate return and vent clearance. Right-side flue location matters for routing. Pre-charged coil pairs simplify field connections. Estimate 4-6 hours for experienced crews, longer if existing ductwork needs modification.
Warranty & Reliability
Ten-year coverage on parts and labor applies to original owner with online registration. Some components carry extended terms under separate manufacturer warranties. Registration requirement, while protective for the buyer, adds a documentation step. Coverage excludes misapplication, improper installation, and damage from system neglect. Extended warranties available through Online Supply for additional peace of mind.
