Review
The Goodman 3-ton upflow gas furnace and air conditioner system sits squarely in the value segment, offering respectable performance at $732 before any available rebates. Online Supply positions this SKU LS38783850 as an accessible entry point for homeowners replacing aging equipment and contractors managing tight project budgets. The unit combines 97% AFUE heating with 18 SEER1 cooling, two ratings that indicate thoughtful engineering across both seasonal demands.
Performance data reveals competent engineering within realistic limits. The furnace delivers 80,000 BTU heating output through a modulating burner that reduces cycling losses, while the air conditioning side produces 35,000 BTU cooling capacity with a two-stage scroll compressor. The variable-speed ECM blower adjusts between zero and 1,200 CFM based on load conditions, improving efficiency during mild weather. However, the 35,000 BTU cooling output runs lighter than nominal 3-ton sizing, suggesting this performs better in moderate versus hot climates.
Pros & Cons
Pros
- 97% AFUE heating efficiency exceeds most competitors in this price range, reducing gas bills noticeably
- Two-stage scroll compressor with variable-speed ECM blower handles part-load efficiency well, matching capacity to actual demand
- 18 SEER1 rating on the AC side represents solid cooling performance for a budget-friendly unit
- Modulating burner stages heat more responsively than single-stage alternatives, improving comfort and reducing short-cycling
- Energy Star certified, qualifying for utility rebates that can offset initial purchase cost
- PVC exhaust compatibility simplifies installation in retrofit applications where metal venting is problematic
Cons
- 35,000 BTU cooling capacity falls slightly short of typical 3-ton expectations (42,000 BTU), indicating this may be undersized for hotter climates
- 71 dB noise level during operation ranks louder than premium competitors, noticeable in quiet residential settings
- 10-year warranty requires online registration, creating an extra administrative step that some buyers overlook
Who Should Buy
Best For
Homeowners in moderate climates upgrading 15-plus year old systems and contractors installing equipment for price-conscious customers who value dependability. This system particularly suits those who qualify for utility rebates, since the $732 price point becomes even more attractive after incentives.
Consider Alternatives If
Buyers in very hot climates needing maximum cooling capacity should explore higher-tonnage units, and those prioritizing whisper-quiet operation should consider premium alternatives despite higher costs.
Installation
Installation demands standard HVAC practices with some modern conveniences. The unit runs on 115V single-phase 60Hz power, requiring breaker protection between 21.3 and 35 amps, well within typical residential panels. Refrigerant compatibility with both R410A and R22 provides flexibility for retrofit work. Plastic PVC exhaust piping, supported by 50 feet of insulation-wrapped suction line and 3/8-inch liquid line, simplifies residential installation compared to traditional metal venting systems.
Warranty & Reliability
Goodman backs the system with a 10-year comprehensive warranty when activated through online registration, a standard protection level matching mid-tier equipment. The separate evaporator coil warranty ensures that the often-failure-prone cooling component receives dedicated coverage. Registration takes minutes and protects your investment, though some buyers fail to complete it, forfeiting coverage eligibility.
