WaterFurnace Logo

The 700A11 uses WaterFurnace’s exclusive variable capacity technology to provide comfort unlike any system you’ve ever experienced. While other conditioning systems run at one or possibly two capacities (high and low), the 700A11 scales compressor output and airflow to exactly the level needed for any heating or cooling situation.

Every 7 Series unit is computer run-tested to ensure flawless performance at start-up. In the unlikely event it needs to be serviced, your unit is backed by one of the best warranties in the industry.
