You’re probably looking at your furnace and wondering when you should replace it. Either your furnace is indicating signs that you need an update or you just have a knack for being prepared for whatever may come in the future. Either way we are here to help you and give you pointers for what to watch.

Your Current Furnace Is Costing You More Money

A furnace that is no longer working as optimally as it should be loses efficiency over time. Your unit will have to work longer to meet the required temperature which means it will be using more gas (if it’s a gas furnace) or more electricity (if it’s an electric furnace). In return your bills will increase.

Shelling out money for unreasonably frequent repairs that have to be done is a red flag. The parts in your heater are probably so worn out that it constantly breaks down, and replacing the parts might be less cost-effective rather than just purchasing a new one.

Try checking its system and see if it’s up to date with that of what has been available in the market for the past years. Really old setup is prone to constantly break, costing you more money in the long-run than purchasing a new one. A pilot light still present in a furnace is tell-tale indicator that it is time to retire your trusted heater as it has most likely been serving mankind for more than 25 years now.

Another symptom for an old gas furnace that needs to be swapped in for a later model, is when someone or multiple people inhabiting the house start to get symptoms of the flu. Get your unit checked if it is still using gas as this could be signs of carbon monoxide poisoning, caused by a broken heating system that is not working properly.  

The Atmosphere Is Dry And Dusty

Ridding the air of dust and humidifying the environment is one of the features of modern furnaces. When the opposite is happening in your residence, chances are your unit is not functioning properly anymore or it is out-of-date and an update might just be for you.

Take note that low humidity encourages colds, flu and other infections. Viruses at this environment find this favorable and are able to survive longer and better than usual.  Your eyes start to feel dry and irritated and your skin starts to get scaly and itchy.

Although too much humidity is known to cause excessive mucus resulting in congestion, an overly dry environment creates feelings of congestion. You would not want to spend your Christmas with a stuffy nose.

On And Off

This is called “short cycling.” Heating systems automatically shut down when the desired temperature has been achieved and starts operating again when things start getting chillier. Short cycling on the other hand is not a good sign and should be taken seriously. Have your HVAC technician check it and see what their advise would be.


There are more ways to tell that your furnace needs replacing. Ask a professional or have one check yours at home for a complete evaluation. If you don’t have a reliable specialist yet, contact Westshore Mechanical at (616) 837-8088.
