Frequently Asked Questions (FAQs)

Q: Why choose the 115 V version?
The 115 V (single-phase) DFVE is ideal for homes without 208/230 V supply, providing all the advanced features in a standard residential voltage configuration.

Q: Is it compatible with heat pumps?
Yes—the DFVE supports cooling and heat-pump applications via its internal EEV and is optimized for R-32 refrigerant.

Q: How quiet is it?
The variable-speed blower, ECM motor, and tight cabinet construction reduce noise and drafts compared to older units.

Q: How often should it be serviced?
At minimum once a year; more frequently in high-use, dusty, or humid environments to maintain performance and warranty eligibility.

Q: What is the benefit of the variable-speed blower?
It modulates airflow according to demand, minimizing drafts, improving dehumidification, lowering fan energy use, and maintaining stable comfort.
