Review
The Goodman 1.5 Ton 15 SEER heat pump from Online Supply represents smart value engineering in the residential HVAC market. This horizontal A-coil configuration targets replacement applications where space constraints matter and budget considerations drive purchasing decisions. At $766, it undercuts many comparable units while maintaining Energy Star certification and a respectable 10-year warranty. Contractors appreciate the straightforward specifications, while homeowners benefit from balanced heating and cooling capacity rated at 18,000 BTU in both modes.
Performance data reveals a unit designed for steady-state operation rather than extreme conditions. The variable-speed ECM blower motor manages the 1,200 maximum CFM efficiently, distributing conditioned air while minimizing runtime in partial-load scenarios. With SEER1 efficiency of 14 and single-stage rotary compression, expect reliable operation in moderate climates but reduced efficiency during peak summer cooling or winter heating demands. The system draws between 11.8 and 20 amps at 208/230V single-phase, fitting standard residential electrical panels without upgrade requirements.
Pros & Cons
Pros
- Variable speed ECM blower motor reduces energy consumption versus fixed-speed alternatives, supporting the 15 SEER rating
- Excellent price point at $766 for an Energy Star rated system with 18,000 BTU cooling and heating capacity
- Flexible backup heat options from 3 to 15 kilowatts allow customization for different climate needs and existing infrastructure
- 10-year warranty with online registration covers parts and labor, protecting your investment long-term
- Compact horizontal A-coil design (34.25 inches tall, 29 inches wide and deep) fits tight attic spaces efficiently
Cons
- Single-stage compressor cannot modulate capacity in extreme temperatures, reducing efficiency compared to multi-stage competitors
- SEER1 rating of 14 lags behind newer SEER2 standards and higher-efficiency models in the market
- 70 dB noise level at full load exceeds some homeowner comfort preferences, particularly in quiet neighborhoods
Who Should Buy
Best For
Contractors replacing older 1.5 ton systems on tight budgets and homeowners in moderate climates seeking balanced efficiency and affordability. This unit works best in regions without extreme temperature swings where single-stage cooling meets seasonal demands reliably.
Consider Alternatives If
Anyone in severe climate zones, high-humidity regions, or homes requiring premium efficiency should explore dual-stage or variable-capacity compressor models instead.
Installation
Installation requires standard refrigerant line connectivity using 3/8 inch liquid and 3/4 inch suction lines, with 3/4 inch insulation thickness on suction to prevent condensation. The horizontal orientation suits attic mounted applications where headroom limits vertical coil placement. Most qualified technicians complete install in 4 to 6 hours. The 50-foot refrigerant line set included reduces material costs and simplifies first-time jobsite setup.
Warranty & Reliability
Goodman backs this unit with 10 years of parts and labor coverage upon online registration, a strong commitment for the price point. This protects against compressor failure, motor burnout, and refrigerant leaks during the critical first decade of operation. Registration through Online Supply activates coverage immediately, with documentation provided in the included service manual.
