Goodman Heat Pump Reviews: Pros, Cons, Performance and Top Picks

Goodman Heat Pump Review (2024 Update)

Goodman, a low-cost heating and cooling brand founded by Harold Goodman in 1982, has been owned by global HVAC giant Daikin since 2012 . This review provides performance and technical specifications for Goodman's four heat pump models, highlighting top models, pros, and cons.

Goodman Heat Pump Overview

Daikin has reduced the Goodman heat pump lineup to four models :

1. GSZ14 (15 SEER/9.0 HSPF) and GSZ16 (16 SEER/9.0 HSPF): Single-stage heat pumps.
2. DSZC16 (16 SEER/9.5 HSPF) and DSZC18 (18 SEER/9.5 HSPF): Two-stage heat pumps.

Technical Specifications

1. Single-stage heat pumps: Affordable but less efficient, noisy, and may overshoot thermostat set points .
2. Two-stage heat pumps: More expensive but quieter and more comfortable, running at 65% capacity unless setpoint changes or outdoor temperatures fluctuate quickly .
3. Top models: GSZ16 (single-stage) with defrost function and high/low-pressure switches, and DSZC18 (two-stage) with defrost, pressure switches, and ComfortNet Communication compatibility .
4. Compressors: Standard quality in single-stage models, Copeland Ultratech scroll compressor in two-stage models .
5. SmartShift technology: Short-cycle prevention for compressor protection and longevity .
6. Factory-installed filter driers: Remove moisture from refrigerant to maintain effectiveness .

Pros and Cons

Pros:

• Excellent value, combining good quality with low prices .
• Industry-leading warranties, including complete unit replacement for failed compressors .
• All models are Energy Star rated, with potential for significant energy company rebates .
• Nationwide availability of installers and repair parts .
• Use of environmentally-friendly R-410A refrigerant .

Cons:

• Questionable reliability beyond 10 years .
• Limited model options compared to other brands .
• Lower efficiency ratings than competitors' top models (e.g., Lennox XP25, Carrier Infinity 20) .
• Labor costs on repairs not covered beyond 12 months in most warranties .
• No modulating/variable-capacity heat pump offered, unlike other top brands .
• Sold to any HVAC company, not just Goodman-certified installers .

Considerations

1. Trade-off between lower price (12-15 year lifespan, potential mechanical issues) and higher cost (20+ year lifespan) .
2. Climate: In extreme weather, opt for higher efficiency models (20+ SEER), which Goodman does not offer .
3. Comfort: Single-stage models provide poor climate control, two-stage models are better, and modulating/variable-capacity heat pumps (not offered by Goodman) are best .

Conclusion

Goodman heat pumps offer good value for budget-conscious consumers but may not provide the longevity or advanced features of premium brands. Carefully consider your climate, comfort needs, and long-term costs when deciding if a Goodman heat pump is the right choice for your home.
