// Bottom Line

Review

The 1.5 ton Goodman heat pump occupies a practical middle ground in today's HVAC market. Priced at $1,409, it delivers mainstream efficiency without the premium cost of variable-capacity or inverter-driven systems. Goodman's reputation for straightforward engineering shows here, with a focus on delivering 18,000 BTU cooling and heating capacity through proven scroll compressor technology. Online Supply backs this unit with Online Supply branding and full Goodman documentation, making it accessible for both DIY and professional installations.

Performance metrics tell a solid story. The 16 SEER1 rating and ENERGY STAR certification mean this system consumes roughly 20-30 percent less electricity than older air conditioners rated around 13 SEER. The variable-speed ECM blower motor runs at partial capacity when loads are light, reducing runtime and noise while maintaining comfort. At 72 dBA, it is moderately loud but within acceptable residential ranges. Refrigerant R410A and the single-stage scroll compressor provide reliable operation without exotic maintenance requirements.

Pros & Cons

Pros

  • 16 SEER efficiency rating meets ENERGY STAR requirements and reduces operating costs by approximately 20-30% versus baseline models
  • Variable-speed ECM blower motor automatically adjusts to 1,200 CFM maximum, improving comfort and reducing energy waste during partial-load operation
  • Upflow and downflow configuration versatility accommodates both basement and attic installations without requiring separate SKUs
  • Compact footprint at 36 inches tall by 29 by 29 inches suits tight mechanical closets and retrofit applications
  • Scroll compressor design offers proven reliability with low vibration and minimal noise at 72 dBA

Cons

  • Single-stage condenser limits part-load efficiency compared to two-stage competitors, though variable blower partially compensates
  • 72 dBA noise level is moderately loud for units installed near living spaces or bedrooms
  • 3/8-inch and 3/4-inch line sizing requires precise matching during installation or replacement of existing systems

Who Should Buy

Best For

Contractors and homeowners replacing older 13-14 SEER systems who need a dependable, affordable upgrade with straightforward installation. This unit works well for 1.5 ton applications in moderate climates where heat pump performance is reliable year-round.

Consider Alternatives If

Buyers in extreme climates requiring heavy heating backup should evaluate the optional electric heat options carefully, as 3-15 kilowatt capabilities vary by configuration and add cost.

Installation

This coil requires straightforward plumbing with 3/8-inch liquid line and 3/4-inch suction line connections, both sweat valve compatible. The A-coil orientation supports both upflow and downflow mounting, adapting to most indoor unit locations. Electrical demands are minimal, requiring just 12.4 to 20 amps at 208/230V single-phase, making it compatible with standard residential service. Installation guides and service manuals are well documented in Goodman's resource package.

Warranty & Reliability

The 10-year parts warranty, activated by online registration, provides solid peace of mind for a $1,409 investment. This aligns with Goodman's competitive warranty tier and covers manufacturing defects comprehensively. Registration takes minutes and is strongly recommended, as it separates this from shorter-term alternatives.

Frequently Asked Questions

Can this 1.5 ton unit replace my old 2 ton system? +
Not directly without load analysis. A 1.5 ton unit produces 18,000 BTU cooling and heating, versus 24,000 for 2 ton systems. If your home truly needs 2 ton capacity, downsizing risks inadequate comfort. Have a contractor calculate cooling load before substituting.
What do the electric backup heat options mean for installation? +
Optional 3-15 kilowatt electric strip heaters can supplement heat pump output in extreme cold. These require separate circuit wiring and controls. Discuss backup heat needs with your installer, as northern climates may require 8-10 kW for reliable cold-weather performance.
How much can the variable-speed blower actually save me? +
Variable ECM motors typically reduce blower energy by 15-25 percent versus single-speed designs by ramping down during light cooling loads. Real savings depend on your climate and thermostat programming. Expect modest monthly utility reductions, not dramatic transformations.
Is 16 SEER good enough, or should I pay more for higher SEER ratings? +
16 SEER is efficient and covers most residential budgets well. Higher SEER units (18-20) often use variable-capacity compressors and cost 30-50 percent more. The payback period for premium SEER rarely justifies the expense unless you plan 20-plus year ownership.
Does the 10-year warranty cover labor or just parts? +
The 10-year warranty covers parts only. Labor costs are your responsibility or your installer's, depending on contractual terms. Always clarify labor coverage separately with your service provider before purchase.
