Why this unit

The 700A11 was the first variable-capacity geothermal unit offered to homeowners, and it is still the benchmark. Instead of switching between one or two fixed speeds, it glides anywhere from 20% to 130% of nameplate capacity, the widest range in the industry, so it delivers exactly the heat or cooling the house needs at that moment.

That constant right-sizing is why it posts 47.0 EER cooling and 5.2 COP heating, roughly 30% better than any two-stage geothermal unit, and why rooms stop swinging between too warm and too cold.

Best for: Owners who want the best running costs available, full stop.

  • Variable capacity, 20% to 130%, the industry's widest range
