Review
Goodman's 2-ton gas furnace and air conditioner system represents the practical middle ground in HVAC equipment selection. Distributed under the Online Supply SKU LS38343850, this downflow configuration combines a 40,000 BTU furnace with a 24,000 BTU condenser unit, serving the substantial residential replacement market where contractors balance performance, durability, and project margins. The downflow A-coil design makes it adaptable to basement installations common in many regions.
This system delivers 14 SEER cooling efficiency with a single-stage rotary compressor and 80% AFUE heating via a two-stage gas burner. The multi-speed blower motor reaches 1200 CFM maximum, providing adequate air distribution for typical home sizes. Refrigerant compatibility with R410A or R22 supports retrofit flexibility. At 71 dB operating noise and 22 pounds unit weight, it remains relatively compact for tight installation spaces without sacrificing cooling output.
Pros & Cons
Pros
- 14 SEER cooling efficiency is respectable for non-premium tier equipment and handles 2-ton cooling loads reliably
- 80% AFUE furnace with two-stage burner provides adequate heating output at 40,000 BTU for moderate climate zones
- Multi-speed blower motor with 1200 CFM maximum capacity adapts to varied ductwork configurations and room sizes
- Two-stage heating and single-stage cooling simplify troubleshooting and reduce service call complexity for technicians
- 10-year warranty with online registration offers solid protection without requiring expensive extended coverage purchases
Cons
- No Energy Star certification means this system doesn't qualify for some utility rebate programs that homeowners expect
- 80% AFUE is significantly below modern 95%+ standards, resulting in higher annual heating costs for end users
- Single-stage compressor lacks variable capacity, so it cycles on and off rather than modulating for better comfort and efficiency
Who Should Buy
Best For
Contractors handling replacement jobs in moderate climate zones where upfront equipment cost directly impacts job profitability. This system works well for budget-conscious homeowners willing to accept standard efficiency in exchange for reliable performance and lower installation costs.
Consider Alternatives If
Homeowners in cold climates should pursue higher AFUE furnaces, and anyone prioritizing minimum operating costs should compare 16+ SEER units despite the price premium.
Installation
This downflow unit requires metal exhaust flue connections and standard 120V, 60Hz single-phase power within 14.3 to 25 amp breaker capacity. Suction and liquid lines measure 3/4-inch and 3/8-inch respectively, with 50 feet of pre-insulated suction line included. Installation height is 34.5 inches with 14-inch width and 28.75-inch depth, making it suitable for compact mechanical rooms. Straightforward two-stage heating integration simplifies controls.
Warranty & Reliability
Online Supply backs this unit with a 10-year warranty activated through online registration. This coverage is standard for mid-tier Goodman equipment and protects against manufacturing defects and component failures. Unlike some premium brands, registration is required to activate coverage, so contractors should confirm homeowner completion. Coverage typically excludes labor and shipping.
