Why You Should Buy the Lennox ML193E Gas Furnace

Posted: 2021-03-23

An old, inefficient furnace can be a pain in the neck. Not only does it fail to provide your desired temperature, but it also costs a lot to operate. Trying to keep up with one does more harm than good. That’s why here at Four Seasons Air Specialists, we help homeowners like yourself to evaluate their existing heating systems and see if they need to upgrade to a new one. As your top heating company in Grant MN, our goal is to make your home as energy-efficient and comfortable as possible.

With that in mind, allow us to introduce one of the high-efficiency furnaces from Lennox’s Merit Series: the ML 193E.

Features of the Lennox ML193E Gas Furnace

The Energy Star Factor

Different gas furnace efficiency requirements and labels are used for certain regions of the country. In the southern half of the U.S., where homes generally need less heating, certified gas furnaces will be labeled with a unique “U.S. South” ENERGY STAR logo. These systems are up to 11 percent more efficient than traditional furnaces.

Because of the many features they offer, high-efficiency furnaces are recommended not only by professionals, but the U.S. government itself, which particularly presents a federal tax credit of up to 30 percent, or up to $1500 if you invest in a high-efficiency furnace for your home.

ENERGY STAR-approved furnaces have higher Annual Fuel Utilization Efficiency (AFUE) ratings and higher efficiency blower motors, making them more efficient than regular models.

To receive the ENERGY STAR label, a furnace should meet strict energy efficiency guidelines set by the U.S. Environmental Protection Agency (EPA). When you choose an ENERGY STAR-certified furnace and take steps to optimize its performance, you can improve your home’s comfort while saving energy in the process. This results in lower energy costs as it also protects the climate by helping prevent harmful carbon pollution and reducing other greenhouse gases.

Also, when your home is properly insulated and air sealed, you can get better heating performance from your ENERGY STAR-qualified furnace.

Standard Features

The ML193E comes with a 20-year Limited Extended Warranty on the heat exchanger. Lennox also offers a 5-year Limited Warranty on covered parts. With registration, this product may be eligible for valuable 10-Year Limited Extended Warranty coverage.

Every component of the ML193E has proven itself through extensive testing in our research labs. So you can take comfort knowing the furnace will deliver reliable performance, season after season.

The ML193E offers continuous comfort at a smart price. But value doesn’t mean compromise. It’s still built to exacting Lennox® standards, with the Lennox commitment to your comfort.

When the ML193E is paired with a Lennox® heat pump, it creates a system that can automatically alternate between electricity and gas to keep you warm. So you’re always using the most energy-efficient way to keep comfortable.

Energy Efficiency

Compared to older, low-efficiency models, the ML193E has an efficiency rating of 93 percent AFUE that can save you hundreds of dollars in heating costs per year.

When paired with a Lennox® heat pump, the ML193E creates a system that can automatically alternate between electricity and gas fuel to keep you warm. So you’re always using the most energy-efficient way to keep comfortable.

The blower compartment of the ML193E is tightly sealed, permitting less than 1% air leakage. This means more of your air and energy go toward keeping you comfortable.


The ML193E’s Power Saver constant-torque motor adjusts airspeed based on demand, helping the furnace use less energy in heating and cooling modes. The ability to adjust airflow based on demand makes this furnace 46% more efficient than standard motors.

This furnace has a Duralok Plus heat exchanger that is constructed from patented ArmorTuf steel that captures waste heat, and a stainless steel secondary heat exchanger that allows the unit to achieve industry-leading efficiency levels. This solid component exceeds industry requirements and extends the furnace’s life.

Its SureLight® ignitor is designed with silicon nitride construction for long product life and reliable operation.

Its SureLight® integrated control board ensures full control of furnace operation.

To further lessen heat loss, Lennox designed the ML193E with an elegantly-styled, durable steel cabinet with a high-quality paint finish.
