Goodman
3.5 Ton Heat Pump
Goodman Up to 15.2 SEER2 Single-Stage, R-32 | GLZS4BA4210
$2,543.99
A 3.5 ton heat pump produces 42,000 BTU of heating and cooling for larger single-family homes around 1,800 to 2,100 square feet. Buyers at this size are often replacing an older AC-and-furnace pair and considering going all-electric with a single heat-pump system.

Swapping a separate air conditioner and furnace for one heat pump consolidates two systems into one and eliminates on-site fuel burning. The trade-off is planning for cold-weather heat: an all-electric heat pump uses an auxiliary heat strip for backup, while a dual-fuel setup keeps a gas furnace for the coldest days and lets the efficient heat pump handle the rest. Your climate and energy prices decide which makes sense.
Weighing all-electric vs dual fuel for a 3.5 ton system? We'll walk you through it →
Yes — it does both jobs. Going all-electric adds an auxiliary heat strip for backup; a dual-fuel configuration keeps a gas furnace for the coldest days. Which is better depends on your climate and energy costs.
Larger single-family homes of roughly 1,800–2,100 sq ft, confirmed with a load calculation that accounts for both heating and cooling.
All-electric uses an electric heat strip for backup heat. Dual-fuel pairs the heat pump with a gas furnace that takes over in extreme cold, using the heat pump the rest of the time for efficiency.
Usually, if it handled a similar-capacity system before — but it's worth confirming the ducts and blower move enough air, since undersized ducts hurt both heating and cooling performance.
Often yes. Replacing fossil-fuel heating with an efficient heat pump can qualify for federal tax credits and utility rebates. Check current programs before you buy.
