Lennox Merit Series ML180 Gas Furnace

A healthy and comfortable home environment needs a furnace that is both efficient and in excellent operational condition. It’s the kind of system that does its job well without consuming too much energy while maintaining good indoor air quality.

Your furnace is the very piece of equipment that gives you comfort in the midst of a relentless weather. Just like any other appliance, it may fail at some point, blowing cold air instead of warm. Knowing your furnace and what causes it to break down will give you an idea if you can fix the problem yourself, if it’s time to call a professional for repair, or it may be time for it to hang up the gloves.

A trusted heating company in Hugo, MN like Four Seasons Air Specialists can give you expert advice to help you decide which particular furnace best fits your home. In partnership with Lennox Industries, we offer an array of furnaces designed to give you comfort and peace of mind.

When to Consider Replacing Your Existing Furnace

When a furnace is nearing the end of its life, it tends to work harder in order to provide the same level of heat. As your furnace ages, it loses its efficiency, especially if it has not been professionally maintained. This results in higher energy consumption and frequent calls to your heating company for repair or parts replacement. The problem is, the older your furnace, the harder it is to find replacement parts.

If you experience a steady increase in your utility bills and repair costs, replacing your furnace would make more sense.

If your furnace is 15 years or older and it’s making loud noises, you need to pay attention because it may need replacing. Here are some furnace noises to watch out for and might tell you it’s time to upgrade.

A loud bang or pop when turning on the furnace may mean you have dirty furnace burners which delay the burners from igniting, causing an excess of gas to build up. You should never ignore this noise because these small explosions could crack the heat exchanger which is an expensive component to repair.

If your furnace produces a squealing or whining noise, it may be caused by loose, slipping, or fraying blower belt, inadequately lubricated shaft bearings, or a malfunctioning blower motor. If these parts need to be replaced, finding new ones may be difficult and expensive.

If you experience any of these, you might want to consider furnace replacement.

Features of the Merit^® Series ML180 Gas Furnace

Every component of the ML180 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.

From its heavy-gauge steel cabinet and aluminized steel heat exchanger to its sealed blower compartment, the ML180 is built to deliver reliable comfort, year after year.

An AFUE of 80% means 80 cents of every dollar spent on gas goes directly toward heating your home. That can mean potential savings of hundreds of dollars per year when compared to an older furnace.

The ML180 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 hot surface igniter controls furnace operation to ensure reliable, efficient performance.
