Review
Goodman's 3-ton downflow system combines a 100,000 BTU furnace with a matching air conditioner coil to deliver heating and cooling for mid-sized homes. This SKU (LS38783850) positions itself in the contractor-grade segment where reliability and straightforward installation matter more than cutting-edge features. The unit ships ENERGY STAR certified and includes a 10-year warranty with registration, appealing to professionals who value proven performance over marketing hype.
The furnace delivers 96% AFUE efficiency using a two-stage burner and variable-speed ECM blower that adjusts to actual heating demand rather than running full-blast constantly. Cooling capacity reaches 34,800 BTU from a single-stage scroll compressor using R410A refrigerant. The unit maxes out at 2000 CFM airflow with a 208/230V single-phase electrical requirement and 18.7 to 30-amp breaker sizing. These specifications suit residential applications where moderate cooling and steady heating efficiency matter.
Pros & Cons
Pros
- 96% AFUE furnace efficiency with two-stage burner minimizes heating fuel consumption and operating costs
- Variable-speed ECM blower motor matches airflow to demand, improving comfort and reducing energy waste compared to single-speed alternatives
- PVC exhaust compatibility simplifies installation in retrofit applications where traditional metal flues aren't practical
- ENERGY STAR certified with 10-year warranty including online registration protection
- 2000 CFM maximum airflow handles 3-ton cooling capacity effectively for mid-sized residential applications
Cons
- 73.5 dBA noise level is louder than some premium competitors, noticeable in quiet living spaces during operation
- Spec sheet shows both 15 SEER and 16 SEER1 ratings, creating confusion about which efficiency standard applies
- No price listed, making value assessment difficult for budget-conscious buyers comparing alternatives
Who Should Buy
Best For
Contractors installing systems in homes where PVC exhaust venting offers cost or logistics advantages, and homeowners in moderate climates wanting efficient heating without paying for top-tier equipment. The variable-speed motor makes it especially suitable for homes with ductwork challenges.
Consider Alternatives If
Buyers in extremely hot climates requiring heavy cooling loads should look at higher-tonnage units, and those prioritizing whisper-quiet operation may find the 73.5 dBA output frustrating.
Installation
Downflow configuration requires proper ductwork planning in basement or attic installations. PVC exhaust venting simplifies routing compared to metal flues, reducing installation labor in tight spaces. The compact 30 by 21 by 21 inch footprint fits most equipment closets or utility rooms. Technicians need standard refrigerant recovery equipment and proper electrical disconnect sizing. Pre-charge and startup typically require 2 to 3 hours of labor.
Warranty & Reliability
The 10-year parts warranty requires online registration to activate full coverage, protecting against compressor and heat exchanger failures. This warranty is solid for mid-tier equipment but shorter than some premium competitors offering 12 to 15 year coverage. Registration is straightforward and necessary documentation should be retained for any future service claims.
