Dealing with an old, inefficient furnace is more than just a headache; it is dangerous. In fact, keeping up with a poorly functioning heating system can be detrimental to your health and your family’s safety.

Marsh Heating and Air Conditioning is an HVAC company in New Hope, MN that values your comfort as well as your safety. That is why we partnered with Lennox Industries, one of the prime makers of innovative furnaces designed to meet your heating needs and comply with the government’s safety requirements.

Why an Old Furnace is Dangerous

Two of the main causes of dangers of old furnaces are associated with the their age and heat sources. Old furnaces, particularly those who are improperly maintained, are at a high risk of emitting carbon monoxide, a colorless, odorless gas that can kill, especially when a person is exposed to this chemical over an extended period of time. Since your furnace distributes the heated air all throughout your home, it can also carry with it fatal amounts of carbon dioxide without you even knowing it. Since carbon monoxide is odorless, it can be difficult to identify if your ductwork has a leak. Having said that, if you or your family has been experiencing flu-like symptoms, this could indicate that there is a carbon monoxide leak in your home.

In addition, an old furnace is a fire hazard. A gas furnace’s burner should produce a solid blue flame. But if it has a yellow color or is flickering, you should call your trusted HVAC technician for help as this could mean your home is leaking carbon monoxide and your furnace could start a fire at any time.

On top of your safety, an old, inefficient furnace is also more expensive to operate compared to a new one. Outdated furnaces can’t keep up with the efficiency of the latest models. This is especially true if you have a system that has an AFUE rating lower than 80 percent, which is the minimum requirement for all new furnaces these days.

The moving parts of older furnaces are less efficient and can fail at any moment, costing you a lot of money on repairs. Unfortunately, the older the furnace is, the harder it is to find replacement parts.

To avoid these problems altogether, consider getting a new, more energy-efficient furnace.

Features of the Lennox EL280 Gas Furnace

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 include special sound-absorbing materials that further reduce sound for even quieter operation.
