Review
Goodman's 1.5 ton horizontal heat pump and furnace system represents competent mid-range equipment for contractors and homeowners balancing efficiency against budget constraints. The package combines a 60,000 BTU gas furnace with 18,000 BTU cooling capacity, arriving preassembled for quicker jobsite installation. SKU LS38343850 replaces the older GSZ140191 model and carries Energy Star certification, positioning it as a genuine efficiency upgrade over legacy single-stage systems from the 2010s.
Performance metrics tell the efficiency story clearly: the furnace delivers 96% AFUE, which converts nearly all fuel to usable heat compared to 80% units common in older homes. On the cooling side, 14 SEER1 rating meets modern standards without exceeding them, meaning real-world seasonal efficiency sits solidly in the middle tier. The variable-speed ECM blower motor adapts airflow between 0-1200 CFM, reducing fan energy waste during mild weather when full-capacity operation isn't needed. Two-stage burner operation minimizes short cycling, a key factor in consistent indoor temperatures and fuel economy.
Pros & Cons
Pros
- 96% AFUE furnace efficiency significantly reduces heating costs compared to 80-90% single-stage units
- 14 SEER1 cooling efficiency meets Energy Star requirements with $0 asking price reflecting clearance value
- Variable speed ECM blower motor delivers up to 1200 CFM with quieter, more flexible operation than fixed-speed alternatives
- Two-stage burner minimizes short cycling and provides modulating heat output for better comfort
- Horizontal A-coil configuration fits tight attics and closets where vertical setups won't work
- Lifetime heat exchanger warranty plus 10 years parts coverage with online registration offers strong protection
Cons
- Single-stage compressor lacks the efficiency gains of two-stage or variable-capacity cooling systems in partial load conditions
- 70 dBA sound level runs louder than newer two-stage compressor designs, particularly during full cooling cycles
- 1.5 ton capacity is undersized for homes larger than 1800-2000 square feet in moderate climates
- R410A refrigerant requires EPA certification for technician service, limiting DIY maintenance options
Who Should Buy
Best For
Contractors retrofitting horizontal HVAC setups in space-limited homes and homeowners in moderate climates (zones 4-5) seeking efficient year-round heating and cooling without premium equipment costs. This system works well for 1200-1800 square foot homes where single-stage performance meets actual load requirements.
Consider Alternatives If
Buyers in hot climates needing aggressive cooling capacity or those prioritizing ultra-quiet operation should explore variable-capacity compressor models with two-stage or modulating cooling for better efficiency at partial loads.
Installation
This horizontal A-coil configuration requires upflow ductwork and fits standard attic or closet spaces measuring at least 34.5 inches tall by 17.5 inches wide by 28.75 inches deep. Electrical demands remain modest at 115V single-phase 60Hz with breaker sizing between 11.8 and 20 amps. Refrigerant lines use 3/8 inch liquid and 3/4 inch suction connections with standard sweat valve fittings. PVC exhaust venting accommodates plastic flue pipe, simplifying installation in many retrofit scenarios.
Warranty & Reliability
Goodman backs the heat exchanger with lifetime coverage, a significant advantage for furnace longevity concerns. Parts receive 10 years protection upon online registration, though labor typically requires separate service contracts. This tiered approach provides peace of mind on major components while clarifying that extended repair coverage involves additional cost. Lifetime heat exchanger coverage particularly appeals to homeowners planning to occupy homes long-term.
