Review
The Goodman HKSC19CB represents the sweet spot in the mid-range heat pump market. This 3-ton unit combines practical engineering with accessible pricing, making it a workhorse choice for residential HVAC contractors and cost-conscious homeowners. Weighing just 9 pounds and measuring 24 inches wide by 21 inches deep, it fits standard equipment pad footprints without modification. Goodman's reputation for no-frills durability backs this model, supported by solid efficiency metrics and straightforward service parts availability.
Performance data justifies the efficiency claims. The unit delivers 35,000 BTU cooling capacity with an 18 SEER rating and 64,800 BTU heating output using R410A refrigerant. The variable-speed ECM motor adjusts airflow between part-load and full 1,375 CFM capacity, reducing runtime on mild days and noise during shoulder seasons. Two-stage compressor staging means the system rarely runs at full bore, extending component life and reducing energy spikes. Operating at 208, 230, or 240 volts single-phase, it matches most residential electrical panels without expensive upgrades.
Pros & Cons
Pros
- 18 SEER efficiency rating beats the industry baseline and qualifies for Energy Star, lowering operating costs in cooling-heavy months
- Variable-speed ECM blower motor delivers 1,375 CFM maximum with modulating capacity, reducing noise and improving temperature consistency
- Two-stage condenser design allows partial-load operation during mild weather, cutting energy waste when full capacity isn't needed
- Two-stage scroll compressor provides reliable long-term performance and smoother operation than single-stage alternatives
- Generous 10-year warranty with online registration protects your investment against manufacturing defects
Cons
- 72 dBA noise level is noticeably louder than high-end inverter-compressor units, which may concern noise-sensitive homeowners
- R410A refrigerant is older technology and less efficient than newer R32 or R454B alternatives found in premium systems
- Heating output of 64,800 BTU requires electric backup heat in cold climates, adding operational costs in winter
Who Should Buy
Best For
Contractors installing systems in middle-market new builds and replacements will appreciate the balance of efficiency, reliability, and install-friendly design. Homeowners in mild-to-moderate climates who prioritize energy savings without stretching into premium-tier pricing will see real ROI within 3-5 years.
Consider Alternatives If
Buyers in harsh winter climates needing strong heating performance or those seeking the quietest, most efficient technology should evaluate higher-capacity units or inverter-driven systems.
Installation
Installation favors experienced technicians. The system requires 57 to 60-amp circuits depending on configuration, with maximum breaker size of 60 amps for circuit one and 50 amps for circuit two. Sweat-type connections use 3/8-inch liquid and 7/8-inch suction lines with 3/4-inch insulation. Line sets ship up to 50 feet, accommodating indoor-to-outdoor distances without additional component purchases. Standard tools and Goodman's detailed installation manual make setup manageable for certified installers.
Warranty & Reliability
Goodman backs the HKSC19CB with a full 10-year parts and compressor warranty upon online registration. This coverage protects against manufacturing defects but excludes wear items, refrigerant loss from leaks, and damage from improper installation or neglect. Registration is free and straightforward, making the warranty accessible. For a unit at this price point, 10 years is competitive and reflects confidence in durability.
