S97V (Downflow/Horizontal)

Enjoy greater comfort and performance thanks to a Modulating Operation that offers a more consistent indoor environment — keeping cold spots to a minimum.

Quiet and efficient comfort is what you get with a Mainline Gas Furnace. The new patented heat exchanger design provides improved airflow, which reduces operating sound by 20%. The variable-speed ECM motor also contributes to a quiet, more efficient operation. It’s engineered to provide better humidity control while using less power. Overall, this is one of the quietest furnaces on the market. And because it’s high-efficiency, your monthly energy bill will benefit, too.

Reliability is of the utmost importance when it comes to your home’s comfort. Our gas furnace comes standard with the direct spark ignition (DSI), one of the most reliable ignition systems available today.

Protect your home with Mainline's Water Management System. The industry’s first blocked drain sensor will shut off your furnace when a drain is blocked, preventing water spillage and potential water damage to your home. All this and one of the best warranties in the industry translate to fewer repair bills and more cozy nights at home.

Easy installation and maintenance features benefit consumers, too. This means savings on installation costs and maintenance. The Mainline gas furnace is designed with diagnostics — our industry-first, 7-segment LED display that makes service calls quick and easy.

Reap Savings Through Maximum Efficiency
The ML98V gas furnace is not only high-performing, it also saves you energy and money. A 98.7% AFUE rating may qualify you for local and/or utility rebates. It’s everything you need in a gas furnace — and more.

Energy Savings are a welcome bonus to any heating system. Maximum airflow and a patented heat exchange design mean the Mainline gas furnace uses fuel efficiently and economically. It gets an ENERGY STAR® rating for maintaining comfortable temperatures while reducing energy consumption and lowering utility bills.
