Lennox Merit® Series ML193 Gas Furnace

When a furnace is approaching the end of its life, it tends to work harder in order to provide the heating demands of your home. As your furnace ages, it loses its efficiency, especially if it has not been regularly maintained by a professional. A poorly functioning furnace can cause a lot of inconveniences to you and your family.

If anyone in your family suffers from allergies caused by airborne dust, pollen, mold or viruses, it means that you have a poor indoor air quality. Old furnaces are unable to moisturize and clean the air to your home which not just triggers allergies but also affects other body organs such as the throat, nose and even the lungs.

Older furnaces can form cracks in the heat exchanger. This results in the leakage of carbon monoxide, a very harmful gas. That is why pros recommend having working carbon monoxide detectors in your home. If there has been a leak of this dangerous gas in your home, you will show symptoms like headaches, nausea, disorientation, irritation of the skin and eyes, and other signs of illness. Opening your windows can help air out your home but it is important to call a heating technician immediately to seal up the leaks and make the necessary repairs.

It is quite normal for you to have higher heating bills when fuel prices go up. However, that may not be the only reason why your heating bills go up during winter. As furnaces go older, they tend to lose their efficiency, especially if they haven’t been regularly maintained. Because of inefficiency, an older furnace needs to run longer to give you that warm, toasty feeling. This extended operation uses more energy and as a result, you have to pay more to get your desired temperature.

If you notice any of these issues, you may need to consider replacing your furnace.

In this article, will highlight a specific furnace in Lennox’s Merit Series, the ML193.
