Are you in the market for a new heating system? If so, you should seriously consider the size of the unit you are deciding on. Far too many homeowners tend to think that the bigger the furnace, the better its performance; this is a myth. Proper furnace sizing is an important factor in choosing the right heating system for your home.

Marsh Heating and Air Conditioning is a leading heating company in Bloomington MN. We possess the knowledge and experience to help you find the furnace that meets your needs without you having to break the bank.

When a Heating System is Oversized

A heating system that’s too large for your home tends to keep the house warm regardless of the outside temperature. However, it also consumes more fuel, and when the system starts, certain areas may warm up too quickly and get uncomfortably warm before the thermostat is even able to read the right temperature. If your home doesn’t have proper insulation, this heat will easily get away, causing the unit to turn itself on and off (a process called short-cycling). When this happens, the furnace’s lifespan is greatly decreased.

When a Heating System is Undersized

Some homeowners believe that it’s more economical to buy a small furnace because it is significantly cheaper than a larger, high-efficiency unit. But if your furnace is undersized, it doesn’t have enough power to consistently heat your home. Therefore, it will need to run longer to increase the temperature, which puts it at risk of overheating. This problem causes the unit to perform poorly, increase your utility bills, and fail prematurely.

Features of the Lennox EL280E Gas Furnace

The Elite® Series takes the Lennox® promise of exceptional comfort and performance to the next level. This superior product family delivers remarkable efficiency. It’s time to elevate your environment. It’s time for Lennox Elite.

Save money and energy with the EL280E gas furnace. The Power Saver™ constant-torque motor design inside the EL280E gas furnace adjusts airspeed based on demand. Whether you’re heating or cooling, that means you’ll use less energy and see lower utility bills. The EL280E’s constant torque motor is up to 46 percent more efficient than standard motors.

The EL280E gas furnace features a two-stage operation using a bigger flame when heating demands are greater, and a smaller flame when they’re not, so you get more even temperatures and lower gas usage.

The EL280E’s ultra-low continuous fan speed provides a quiet, constant flow of air and enhances indoor air quality devices.

When matched with a Lennox air conditioner or heat pump, the EL280E can improve your cooling Seasonal Energy Efficiency Ratio (SEER), which leads to greater energy efficiency and lower energy costs.

Energy Efficiency

With an efficiency rating of up to 80 percent AFUE, the EL280E can save you hundreds of dollars in heating costs per year, compared to older, low-efficiency furnaces. (Actual savings will vary depending on your area’s fuel rates and your family’s lifestyle.)

Its dual-fuel capability can be incorporated with an electric heat pump to create a dual-fuel system that maximizes comfort and fuel efficiency by smoothly alternating between electric and gas heat, optimizing energy use and minimizing heating costs.

To minimize heat loss and maximize comfort and efficiency, Lennox created a sealed blower compartment for the EL280E.


This furnace has a Duralok Plus heat exchanger that is built from patented ArmorTuf steel that captures waste heat, and a stainless steel secondary heat exchanger that enables the unit to achieve industry-leading efficiency levels. This solid component exceeds industry requirements and extends the EL280E’s lifespan.

Its SureLight igniter increases its lifetime and improves reliability.

Its SureLight control board effectively controls its operation, guaranteeing better reliability and efficiency.

To further lessen heat loss, Lennox designed the EL280E with an elegantly-styled, durable steel cabinet with a high-quality paint finish.

The EL280E includes special sound-absorbing materials that further reduce sound for even quieter operation.
