Review
The Goodman 3 Ton, 16 SEER upflow gas furnace and air conditioner system represents a solid mid-tier choice for residential HVAC replacement. SKU LS38783850 combines proven Goodman manufacturing with modern efficiency standards, delivering an Energy Star certified system that appeals to budget-conscious homeowners and contractors seeking reliable performance without premium costs. This configuration is particularly common in retrofit applications where existing ductwork and venting infrastructure limit equipment choices.
Performance specs reveal a heating-focused design with genuine strengths. The 97% AFUE rating and 80,000 BTU output provide excellent heating efficiency, while the modulating burner reduces energy waste by varying fire rate based on demand. Cooling capacity reaches 35,000 BTU through a two-stage scroll compressor, though the 18 SEER rating lags some competitors. The variable-speed ECM blower motor adjusts airflow from 0 to 1200 CFM, matching system output to load conditions and reducing ductwork noise.
Pros & Cons
Pros
- 97% AFUE furnace rating exceeds most standard systems, reducing heating costs significantly over time
- Modulating burner adjusts heat output in real-time, improving comfort and reducing short-cycling losses
- Variable-speed ECM blower motor delivers up to 1200 CFM with lower electricity consumption than fixed-speed alternatives
- Two-stage condenser enables efficient operation at partial load, saving energy during mild weather
- PVC exhaust compatibility simplifies installation in many retrofit scenarios, reducing labor costs
- 10-year warranty with online registration provides solid coverage for major components
Cons
- SEER rating of 18 is competitive but not top-tier, trailing premium inverter-driven systems by 2-4 points
- Weight of 30 lbs and compact 21x21x30 inch footprint may complicate installation in tight attic or basement spaces
- R410A refrigerant requires EPA certification and proper recovery procedures during service or replacement
- 71 dB decibel level is moderate-to-loud during operation, potentially noticeable in quiet residential settings
- Tonnage specification shows 5 tons for cooling but only 3 tons, creating confusion about actual capacity
Who Should Buy
Best For
Homeowners in northern climates or those with high heating costs will see the greatest benefit from this 97% AFUE system. Contractors installing replacement systems in homes with plastic vent exhausts will appreciate the simplified venting requirements and straightforward upflow configuration.
Consider Alternatives If
Buyers seeking maximum cooling efficiency (SEER 20+) or those in noise-sensitive environments should explore alternatives with higher SEER ratings or scroll compressor upgrades designed for quieter operation.
Installation
Installation proves straightforward for standard upflow applications. PVC exhaust requirements simplify venting compared to metal B-vent systems, saving installation time and cost. The 21x21x30 inch footprint fits most mechanical closets, though tight spaces may challenge technicians. Electrical requirements are modest at 208/230V single-phase 60 Hz, with breaker sizing between 21.3 and 35 amps. Suction and liquid line sizes are standard, requiring 3/8 inch and 7/8 inch connections respectively.
Warranty & Reliability
Goodman provides 10-year comprehensive coverage when you register online, covering parts and compressor failure. This warranty is respectable but not exceptional compared to some competitors offering 12 or 15-year terms. Registration is mandatory to activate the full term, so homeowners must document the purchase promptly. Labor costs are the homeowner's responsibility, though the 10-year timeline covers most component failures before natural wear occurs.
