The Goodman GSZC18 wins this head-to-head comparison, taking 2 out of 4 categories. It's the stronger choice for most homeowners, especially those who prioritize most affordable heat pump option in our lineup. That said, the Rheem EcoNet is still a solid product and may be the better pick if you specifically need budget-conscious homeowners who still want smart features.

Cold-climate rated heat pumps maintain heating capacity at sub-zero temperatures, which is critical for New England winters.
Goodman is our go-to when budget is the primary constraint. It's manufactured by Daikin, so the underlying engineering is sound. Our crews install it quickly — usually under a day for a standard ducted replacement. The 10-year parts warranty is actually the best in the budget tier. We're upfront with homeowners: this is a great system for moderate climates, but for inland New England winters, a cold-climate model is a better long-term investment.
Rheem EcoNet is our budget-friendly option for homeowners in milder areas. The included EcoNet thermostat is a nice touch at this price point. Our crews install it in a single day for ducted replacements. For inland New England locations that regularly see single digits, we always pair it with backup heat strips and have an honest conversation about upgrading to a cold-climate model.
