7 Series 700A11
The most efficient heating and cooling unit you can put in a house.
- 47.0
- EER cooling
- 5.2
- COP heating

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.
