Review
The Goodman 1.5 ton gas furnace and air conditioner combo (model LS38343850) sits squarely in the mid-market sweet spot. It's built for contractors who need reliable equipment without bleeding customer budgets dry. Goodman has earned respect for producing sturdy, repairable equipment, and this upflow configuration handles both heating and cooling duties in one compact package measuring just 22 inches tall.
Performance metrics show a 60,000 BTU heating capacity with 80% AFUE efficiency and 18,000 BTU cooling output at 15 SEER. The two-stage burner adjusts heat delivery for comfort, while the high-efficiency multi-speed blower maxes out at 1,200 CFM. Energy Star certification confirms it meets federal baselines, though the 80% AFUE increasingly looks modest compared to 95%+ options. Cooling capacity runs 2.5 tons on the condenser side, so slight oversizing occurs relative to the 1.5 ton advertised capacity.
Pros & Cons
Pros
- Two-stage burner delivers better comfort than single-stage units by modulating heat output
- High-efficiency multi-speed blower optimizes airflow at 1,200 CFM maximum capacity
- Energy Star certified with 80% AFUE meets most regional efficiency standards
- 10-year warranty with online registration provides solid long-term protection
- Compact upflow/downflow design fits tight installation spaces at 22 inches tall
Cons
- 15 SEER rating lags newer units hitting 16+ SEER, increasing long-term operating costs
- Scroll compressor is durable but noisier at 71.5 dB compared to variable-speed alternatives
- 80% AFUE is becoming dated as 95%+ AFUE systems become mainstream
Who Should Buy
Best For
Contractors replacing older 13-14 SEER systems in residential applications will appreciate the straightforward upflow installation and proven Goodman reliability. Homeowners on tight budgets who prioritize upfront cost over maximum efficiency savings will find good value here.
Consider Alternatives If
Skip this unit if you need cutting-edge efficiency, live in extreme climates, or want a system designed for the next 15 years, as AFUE and SEER standards are rising industry-wide.
Installation
This upflow unit requires standard metal exhaust flue venting and 208/230V single-phase 60Hz power, needing a 12.4 to 20 amp breaker. Refrigerant lines use 3/8-inch liquid and 3/4-inch suction connections with 50 feet maximum line length. Installation demands proper A-coil integration and ductwork verification. Most HVAC pros can handle this in a single day, making retrofit projects straightforward.
Warranty & Reliability
Goodman backs this system with a 10-year parts and labor warranty upon online registration. That's competitive for the price point and covers the compressor, blower motor, and heat exchanger. Registration is mandatory to activate coverage, so contractors should handle this paperwork upfront rather than leaving it to homeowners.
