Signs Telling You Need a New Furnace

Most homeowners only consider getting a new furnace when their existing unit has already completely failed. However, the best time to shop for a new system is before it totally breaks down. There are signs telling you that your furnace is due for a replacement.

If you notice any of these signs, it is probably time to get a new furnace.

An Old Furnace

A well-maintained heating system can last up to 12-15 years. If your unit is past its 15-year mark and starts to show a decline in performance, there is a high possibility that it needs a replacement sooner than later. Even if the system still works, it no longer operates at maximum efficiency, which causes it to consume more energy.

Older furnaces require more maintenance than newer ones. When a furnace is approaching the end of its life, it tends to break down repeatedly, costing you hundreds if not thousands of dollars in repair — not to mention the level of stress it brings to your family.

Old furnaces usually work harder in an attempt to provide your family’s heating needs. This extra burden on the unit results in higher energy bills and recurrent repairs. Depending on the number and types of repairs, these costs, when added up, can be almost as much as the cost of a new unit.

If you observe a constant increase in your utility bills without a parallel increase in use, consider getting a new furnace. The amount of money you save in the long run can be equivalent to a new, more efficient heating system.

Frequent Sickness in the Family

As a furnace ages, cracks can develop in the heat exchanger, which can cause the discharge of carbon monoxide into your home undetected. This colorless, odorless, deadly gas can cause certain health issues and symptoms such as a headache, nausea, weakness, dizziness, blurred vision, and shortness of breath. For your family’s safety, it’s best to contact an HVAC professional to determine whether your existing furnace is still safe to use or if it needs a replacement.

Hot and Cold Spots

Inconsistent heating is one of the results of an inefficient furnace. If you have to adjust the thermostat again and again because you feel that some rooms are warmer than others, you may be dealing with a furnace that lacks the power to effectively heat your entire home. Older, inefficient heating systems are unable to properly distribute heated air throughout the home.

A Noisy Furnace

If your furnace has been producing unusual sounds like popping, hissing, and banging, it could mean that it’s starting to deteriorate. While you can think that it may only need a simple repair, but there’s the possibility that it’s actually nearing the end of its life. An HVAC professional can give you expert advice on whether your furnace needs a repair or a replacement.

Poor Indoor Air Quality


An underperforming furnace results in an unclean, unsafe indoor air. If you have someone in your household who suffers from allergies caused by airborne dust, pollen, mold or viruses, operating an inefficient furnace puts them at risk of worsening their condition. Old furnaces are unable to properly humidify and clean the air in your home, which not only prompt allergies but also affect other body organs such as the throat, nose and even the lungs. Poor indoor air can also result in too much dryness in your indoor air, damaging the walls, wood flooring, furniture, and plants in your home. Furthermore, if you notice plants starting to wilt, or family members who are suffering from dry eyes and itchy throats or headaches, you may need to consider getting a new furnace. These are clear signs your furnace is unable to keep a healthy indoor air.
