Review
Goodman's 3 ton upflow gas furnace and air conditioner system represents practical, no-nonsense equipment engineering for the mid-market. Configured as an integrated unit, it pairs a two-stage gas furnace with a single-stage reciprocating compressor air conditioner, designed primarily for retrofit applications where existing ductwork can be leveraged. This SKU (LS38783830) from Online Supply targets contractors and homeowners balancing upfront cost against dependable performance in moderate heating and cooling climates.
Performance specs show 100,000 BTU heating output with 80% AFUE efficiency and 36,000 BTU cooling rated at 13 SEER. The high-efficiency multi-speed blower motor handles up to 2,000 CFM across both heating and cooling cycles. This combination delivers reasonable comfort without premium efficiency penalties. Operating voltage is 120V single-phase at 60 Hz, with electrical demand between 19.1 and 30 amps, making it compatible with standard residential service panels. R410A refrigerant ensures compliance with current EPA regulations.
Pros & Cons
Pros
- Two-stage burner heating with 100,000 BTU output covers most residential applications efficiently
- 13 SEER rating and high-efficiency multi-speed blower motor keep operating costs reasonable
- 80% AFUE furnace efficiency is respectable for non-condensing models and widely serviceable
- 10-year warranty with online registration provides solid coverage for peace of mind
- A-coil upflow/horizontal configuration fits standard retrofit installations with minimal ductwork changes
Cons
- Not Energy Star certified, meaning it trails SEER 14+ competitors in cooling efficiency
- Single-stage compressor lacks variable capacity, reducing comfort during partial-load conditions
- 74 dB noise level runs louder than variable-speed alternatives, noticeable in quieter homes
Who Should Buy
Best For
Contractors completing cost-effective residential replacements and homeowners in moderate climate zones seeking reliable heating and cooling without premium pricing. This system works well for properties where efficiency standards are adequate rather than exceptional.
Consider Alternatives If
Buyers prioritizing minimum operating costs, those in hot climates requiring sustained cooling, or homeowners who value quiet operation should explore SEER 16+ and variable-speed compressor models.
Installation
Installation requires standard sweat connections using 3/8-inch liquid line and 7/8-inch suction line piping with 3/8-inch insulation thickness. Proper sizing assumes 30-foot lineset maximum, though professional HVAC technicians should verify refrigerant charge and airflow against local codes. Upflow configuration fits attic or utility closet placement. Metal exhaust flue is mandatory, and 30-inch height, 21-inch width/depth footprint needs verification before ordering.
Warranty & Reliability
The 10-year warranty applies when you register the unit online after purchase, covering compressor and parts. This is competitive for mid-tier equipment but requires proactive registration to activate. Online Supply manages claims through Goodman's network, though response times vary by region. Proof of professional installation may be required, so retain contractor documentation.
