3 Things You Should Consider Before Buying a New Furnace

A Feature on the Lennox EL180E Gas Furnace

For most homeowners, replacing an old, inefficient furnace is a major decision because it involves not only the comfort but also the safety of everyone in the home. Buying a new heating system can be overwhelming, since there are a lot of factors that need to be taken into consideration before deciding on a particular model.

Four Seasons Air Specialists is your friendly heating company in Shoreview MN that offers professional advice on choosing the furnace that suits your needs.


Old furnaces, particularly those between 10-15 years of age, naturally experience a decline in performance, causing your utility and repair costs to move upwards.

If you have an old furnace that’s unable to provide your family’s heating needs, a new furnace could be the answer to your problem.

Fuel Type

Most furnaces run on either gas, electricity or oil, and you should choose a system that uses the right fuel your home is equipped with. A gas-fired unit tends to be more efficient than its oil-based counterpart, and these days, AFUE ratings range from 80 AFUE up to 98 AFUE. Understand that fuel costs are not fixed, and in some cases, they tend to fluctuate over 10 percent per year. Ask your preferred HVAC company for expert advice.

Thermostat Compatibility

If you’re still using one of those conventional thermostats, you might need to upgrade it when you replace your furnace. While many thermostats work just fine with an array of furnaces, but there are some models that don’t. Also, there are thermostats designed to boost your furnace’s efficiency.

Features of the Lennox EL180E Gas Furnace

The EL180E has an efficiency rating of up to 80 percent AFUE, which can save you hundreds of dollars in heating costs per year, compared to older, low-efficiency furnaces.

When compared to a standard single-speed motor, the Power Saver motor delivers significant energy savings, without sacrificing comfort. Its constant torque motor adjusts airspeed based on demand, helping the furnace use less energy in heating and cooling modes. The EL180E is 33 percent more efficient than standard motors. When working with an air conditioner or a heat pump as part of a complete Lennox home comfort system, it can increase overall cooling efficiency by one or more SEER points. That translates to more savings on energy after the last snowfall.

Its Power Saver™ motor operates at constant torque to help maintain consistent airflow. This technology not only provides energy boost capabilities improving the overall system efficiency, similar to a variable speed furnace but also delivers higher SEER ratings in cooling mode. In continuous fan mode, this technology helps keep energy waste to a minimum.

The consistent flow of air helps keep temperatures inside your home comfortable, even as the weather outside is changing. And because it’s continually rotating, the Power Saver motor delivers quiet heating performance, removing the noisy startup sounds associated with single-stage motors.

Every component of the EL180E 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.

To minimize heat loss and maximize comfort and efficiency, Lennox created an insulated blower compartment for this model.

For your peace of mind, the EL180E comes with a 20-year limited warranty on the heat exchanger and a 10-year limited warranty on all remaining covered components.


The EL180E 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.

The EL180E includes special sound-absorbing materials that further reduce sound for even quieter operation.

To further lessen heat loss, Lennox designed the EL180E with an elegantly-styled, durable steel cabinet with high-quality paint finish.

Its top vent with rotatable inducer simplifies horizontal installations.

Its Surelight Igniter’s nitride design provides long product life and reliable operation.

The EL180E’s Surelight Integrated Furnace Control manages furnace operation and provides direct readout diagnostics for quick troubleshooting. That means your technician won’t take that much time finding out what’s wrong with the system.
