// Bottom Line
This Goodman system delivers reliable heating and cooling at an exceptional price point for contractors and homeowners on a tight budget. It's best suited for moderate climates where 80% AFUE heating is acceptable and cooling demands don't exceed 30,000 BTU.

Review

Goodman has long served the value-conscious segment of the HVAC market, and this 2.5-ton combo system exemplifies their approach. At $89, it undercuts many competitors significantly while delivering functional heating and cooling for residential applications. The system operates in upflow or horizontal configuration, making it flexible for different installation scenarios. This SKU (LS38343850) represents the no-frills option, prioritizing affordability over cutting-edge efficiency.

Performance specs tell a practical story. The 100,000 BTU furnace achieves 80% AFUE efficiency, meaning reasonable but not exceptional heating performance. Cooling capacity reaches 30,000 BTU with 14 SEER rating, adequate for moderate zones. The variable-speed blower motor pulls up to 2000 CFM, optimizing air distribution. Two-stage burner firing and single-stage cooling keep complexity down. Operating on 208/230V single-phase power, it requires a 17.1 to 25-amp breaker, fitting standard residential electrical panels.

Pros & Cons

Pros

  • Exceptional value at $89, making it accessible for budget-conscious buyers
  • 14 SEER cooling efficiency meets mid-range expectations for newer equipment
  • Variable-speed blower motor optimizes airflow and reduces energy waste
  • Two-stage burner provides better comfort control than single-stage alternatives
  • 10-year warranty with online registration covers manufacturing defects
  • Dual fuel compatibility, accepting both natural gas and propane

Cons

  • 80% AFUE is below modern standards, meaning 20% of heating energy is wasted up the flue
  • Not Energy Star certified, limiting rebate eligibility in many regions
  • Metal exhaust flue requirement adds installation complexity and cost
  • Single-stage condenser limits cooling efficiency gains on hot days

Who Should Buy

Best For

Contractors looking to stock affordable equipment for budget-conscious customers and homeowners replacing aging systems in mild to moderate climates. This unit works well for rental properties or applications where upfront cost matters more than premium efficiency.

Consider Alternatives If

Buyers in hot climates needing maximum cooling efficiency, homes in cold regions where heating dominates annual costs, or those pursuing ENERGY STAR rebates should explore higher-efficiency alternatives.

Installation

Installation demands basic HVAC knowledge. The metal exhaust flue requirement means proper venting must be planned before installation, adding both cost and complexity. Unit dimensions of 26 inches tall by 21 inches wide by 21 inches deep fit standard equipment closets. Weight of 22 pounds makes handling straightforward. Refrigerant lines come pre-sized at 3/8-inch liquid and 3/4-inch suction, with 3/4-inch insulation and 50-foot length supplied.

Warranty & Reliability

The 10-year parts warranty requires online registration but provides solid coverage for manufacturing defects. This protects your compressor and major components without cost during the critical first decade. However, coverage excludes labor and shipping, so budget accordingly. Goodman's reputation for honoring claims is solid, though response times vary by region.

Frequently Asked Questions

Why is this system priced so much lower than competitors? +
Lower efficiency ratings (80% AFUE, 14 SEER) reduce manufacturing and engineering costs. Single-stage cooling and basic controls eliminate premium features. Online Supply's direct distribution model cuts retailer markup, passing savings to buyers without sacrificing core functionality.
Can I install this myself, or do I need a licensed contractor? +
Most jurisdictions require licensed technicians for gas furnace installation due to safety codes. The metal flue venting requirement especially demands proper sizing and sealing. Cooling circuit evacuation also requires EPA-certified equipment. Budget $500 to $1,200 for professional installation.
How does 14 SEER compare to newer systems? +
14 SEER represents decent mid-range performance, meeting minimum standards in many states. Modern high-efficiency systems reach 18 to 24 SEER. Your cooling bills will run 15 to 30 percent higher than premium units, but upfront savings often justify this trade-off.
What's the real difference between this and Goodman's 16 SEER models? +
Higher SEER models feature variable compressor speeds and enhanced refrigerant circuits, reducing waste during partial loads. This 14 SEER unit runs single-stage cooling, cycling on and off fully. The premium models cool more efficiently in mild weather, saving energy but costing $2,000 to $4,000 more.
Is the 10-year warranty worth the registration hassle? +
Yes. Registration takes five minutes online and locks in a decade of compressor protection, your most expensive component. Skipping registration voids coverage completely, so spend the two minutes upfront.
