How do I know when to replace my furnace?
6 Signs You Need A New Furnace
For the average homeowner, determining whether or not you need to replace your furnace can be a difficult decision without professional advice. However, there are some signs to look for that indicate your furnace is nearing the end of its’ life. Remember these are just guidelines, and it is highly recommended that you call a professional before deciding to go ahead and replace your furnace.
1. Furnace is older than 15 years
While unfortunately there is no guaranteed expiry date on your furnace, it is generally believed that the lifespan is between 15 and 20 years. Of course, it is entirely likely that your furnace will need replacing sooner, depending on the environment that it is in and the maintenance that it received. But if your furnace more than 15 years old, you should exercise caution and make sure to get it inspected by a furnace and duct cleaning expert if it seems to be lacking.
2. Increased energy bills
If you’ve noticed that your energy bills seem much higher this year when the rates have not increased, this could indicate a deficiency in your furnace. Newer and well-maintained furnaces run more efficiently than older furnaces. Furnace repair may be sufficient to bring those energy bills down low again, however the increase in operating costs may warrant a replacement.
3. Difficulty heating home
One of the clearest indications that your furnace needs to be replaced is an apparent difficulty getting your home to maintain a comfortable temperature. However, it is recommended that you should not turn your heat up too high, as it will cause your furnace to work extra hard. Instead, call a professional to perform an affordable inspection that will let you know the nature of the problem.
4. Excess dust
If it seems like you will never be able to get rid of the dust in your home, it’s not you going crazy – it’s your furnace. One of the major functions of a furnace is to trap and remove dust and allergen particles from the air, making it a critical factor of indoor air quality. If the dust in your home seems to never go away, first try to replace the furnace filter. If this does not solve the problem, speak with a furnace and duct cleaning expert as soon as possible. Internal furnace components can sustain permanent damage if it has not been well maintained. And, going forward, it is recommended to replace your furnace filter every two months to maximize the life of your furnace and ensure healthy indoor air.
5. Strange smell, sound or appearance
If you are like most homeowners, you probably rarely ever go near your furnace. However, you can learn a lot about your furnace by simply being around it. Listen to the sounds it makes, smell for mustiness or leaking gas, and look for any corrosion or cracks in the system. If anything seems off, have a furnace and duct cleaning professional inspect it.
6. Take note of your furnace’s cycles
A well-maintained, good-working furnace will turn on when the thermostat dips below the set temperature, and turns off when it reaches that temperature. However, if it seems like your furnace turns on and off or seems like it is always one, you may want to schedule an appointment for an inspection.
