Review
This Goodman horizontal system represents a solid midrange option for HVAC replacement in homes where space constraints matter. The combination of an 80,000 BTU furnace with 97% AFUE and a 23,600 BTU cooling capacity condenser targets contractors managing attic and crawlspace installations. SKU LS38343850 carries a 10-year warranty and qualifies for ENERGY STAR, signaling genuine efficiency credentials rather than marketing claims.
Real-world performance hinges on the furnace's modulating burner and the condenser's variable-speed ECM blower. The 97% AFUE rating means nearly all fuel converts to heat, with only 3% wasted up the PVC flue. At 16 SEER2 cooling and 71.5 dB operating noise, the air conditioning side delivers respectable quiet operation. However, the single-stage compressor design means cooling capacity stays fixed rather than ramping down in mild weather, a tradeoff against the efficiency gains.
Pros & Cons
Pros
- 97% AFUE furnace efficiency reduces heating costs significantly compared to 80s-era units
- 16 SEER2 cooling rating qualifies for ENERGY STAR and utility rebates, lowering total installed cost
- Modulating gas burner and variable-speed ECM blower motor reduce short-cycling and improve comfort
- Compact horizontal dimensions (21.125 inches H x 17.5 inches W x 26 inches D) fit tight attic spaces
- PVC exhaust compatibility simplifies venting in modern homes without masonry chimneys
Cons
- Single-stage condenser design may cycle more frequently in extreme heat, reducing part-load efficiency gains
- 3-ton condenser paired with furnace creates oversizing concerns if original AC was 2 tons, potentially wasting cooling capacity
- Limited documentation on matched system performance, AHRI certificate references unit pairing but individual component ratings less clear
Who Should Buy
Best For
Homeowners in moderate climates replacing 20+ year old systems who want straightforward efficiency gains without major renovation. Contractors installing in existing horizontal/downflow configurations where ducting allows for proper airflow without major modifications.
Consider Alternatives If
Anyone needing a true 2-ton system should verify tonnage carefully, as this unit ships as 3-ton capacity despite product title saying 2-ton. Those requiring ultra-high efficiency should compare two-stage or variable-capacity equipment.
Installation
Horizontal orientation requires proper drain placement and slightly different ductwork connection geometry than vertical units. The 1200 CFM maximum airflow and 3/8-inch liquid line connections are straightforward for experienced installers. PVC exhaust needs termination at least 3 feet from windows and doors per code. Pre-charge refrigerant configuration (R410A or R22 compatibility) allows flexibility for existing lineset retrofit jobs without complete system evacuation in many cases.
Warranty & Reliability
The 10-year parts warranty requires online registration, a common Goodman requirement that many homeowners overlook. Coverage includes compressor, which typically fails between years 5 and 8 in poorly maintained systems. This protection adds genuine value versus no-name brands offering 5-year limited coverage. Evaporator coil carries separate warranty documentation, important if future refrigerant leaks develop.
