Review
Goodman's 2/3-ton horizontal unit enters the market as a straightforward efficiency play for contractors and homeowners tired of aging single-stage equipment. The SKU GMVM970603BN pairs a scroll-compressor air conditioner with a modulating gas furnace, both tuned for the modern efficiency standard. At 16 SEER and 97% AFUE, this system qualifies for Energy Star recognition and positions itself as a practical middle-ground choice, avoiding both budget-tier performance and premium-tier pricing.
Cooling capacity reaches 24,000 BTU (or 60,000 BTU heating output, though tonnage specs show inconsistency in documentation). The two-stage condenser and modulating burner reduce short-cycling and improve part-load efficiency, while the variable-speed ECM blower motor adapts airflow to demand. Operating at 71 dB with R410A refrigerant and handling up to 1,200 CFM, this unit runs quieter than fixed-capacity competitors and maintains comfort without oversizing.
Pros & Cons
Pros
- 16 SEER cooling efficiency qualifies for Energy Star and many utility rebates, reducing operating costs by 20-30% versus 13 SEER units
- Two-stage scroll compressor and modulating gas burner provide quieter operation at 71 dB and better comfort control than single-stage alternatives
- 97% AFUE furnace with variable-speed ECM blower maximizes heating efficiency, delivering 60,000 BTU across a wider range of operating conditions
- 10-year warranty with online registration covers major components, protecting against compressor and heat exchanger failures
- Compact horizontal configuration (34.5 x 17.5 x 28.75 inches, 118 lbs) fits tight attic and basement spaces where larger systems won't fit
Cons
- Specs list both 2-ton and 3-ton tonnage designations with conflicting cooling/heating BTU values, creating confusion about actual system capacity
- Requires licensed technician installation due to gas connections and venting requirements, adding $1,500-$3,000 to total cost
- 71 dB noise level is acceptable but noticeably louder than premium variable-capacity compressor systems operating at 65-68 dB
Who Should Buy
Best For
Homeowners with existing ductwork seeking a reliable mid-efficiency upgrade for mixed climates where cooling and heating loads are moderate. Contractors looking for an AHRI-certified system (Certificate 7424264) that balances efficiency standards with affordability.
Consider Alternatives If
Anyone in heating-dominant climates who rarely uses air conditioning, or buyers requiring premium efficiency ratings above 18 SEER should explore higher-tier options instead.
Installation
Installation requires a licensed HVAC technician due to natural gas and propane fuel connections, PVC venting requirements, and local code compliance. The horizontal A-coil configuration demands proper ductwork alignment with 3/8-inch liquid and 7/8-inch suction lines. Standard 115V single-phase 60Hz power (15.7-20 amps) fits most residential panels. Plan 4-8 hours for a complete changeout in existing homes.
Warranty & Reliability
Ten-year parts and compressor coverage applies when registered online within 30 days of purchase. This protects against scroll compressor failure and heat exchanger defects but excludes normal wear, refrigerant loss, and improper installation. Registration is straightforward through Goodman's website and provides peace of mind during a unit's peak efficiency window.
