Frequently Asked Questions
Its variable-speed blower ramps airflow up and down gradually instead of switching full-on and full-off, and two-stage heating runs mostly on low fire. Together that means less noise, fewer temperature swings, and steadier comfort.
For larger homes, multi-level layouts, or anyone sensitive to noise and temperature swings, yes — the comfort and quiet are a real upgrade. For smaller, well-insulated homes a single-stage 96% furnace like the ML196E is often the better value. We will give you a straight recommendation at the quote.
Yes — it is dual-fuel ready. Pairing it with a heat pump lets the heat pump carry most of the season and the furnace handle the deep cold, and the heat pump side can qualify for up to $7,500 through the Home Renovation Savings Program.
