Exposure to cold environments is dangerous to your health, but thanks to your furnace, you can remain productive in the day and have a relaxing, peaceful sleep at night. A furnace has the ability to heat and filter your indoor air effectively, giving you the comfort and safety you need when the temperatures become unbearably cold. However, there are times when your heating system will blow cold air instead of warm.

Marsh Heating and Air Conditioning is your trusted heating company in Coon Rapids MN. We have an array of energy-efficient furnaces that can effectively protect you from the cold.

Overheating Issues

When a furnace overheats, it turns itself on and off indiscriminately. This issue is called “short cycling”, which is the main cause of high fuel consumption and furnace failure. A dirty filter can result in your furnace restricting the airflow within the heat exchanger, causing it to work harder than normal. Checking and replacing the furnace filter periodically can help avoid overheating. This practice is one of the easiest things you can do to keep your furnace running smoothly. Do not ignore this issue as repeated overheating can damage the heat exchanger, which is quite a costly part to repair or replace.

Closed registers can also lead to overheating by increasing the pressure in your air ducts. This issue slows down your furnace blowers and decreases the airflow within the system.

A clogged evaporator coil, a dirty blower wheel, or a broken gas valve can also contribute to the overheating of your furnace.

It helps to have your furnace checked by a qualified professional, who can identify the cause of the problem and rectify it to avoid having more serious problems.

However, if the complication is too severe and your unit is too old, it might be wiser to upgrade to a new furnace instead. As the system grows older, finding replacement parts can get more and more challenging.

Features of the Lennox EL280 Gas Furnace

The EL280 can adjust the size of its flame based on heating demand, allowing it to fine-tune your comfort and your energy savings with greater precision than a conventional furnace.

This product comes with a 20-Year Limited Warranty on Heat Exchanger. 5-Year Limited Warranty on covered components. This product may be eligible for valuable 10-Year Limited Extended Warranty coverage with product registration.

The EL280 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.

The EL280’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 EL280 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 EL280 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 EL280.


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 EL280’s lifespan.

The EL280’s 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 EL280 with an elegantly-styled, durable steel cabinet with high-quality paint finish.

The EL280 is equipped with special sound-absorbing materials that further reduce sound for even quieter operation.
