When you have trouble bringing heat inside your home, it may be time to consider replacing your furnace entirely. Most homeowners’ first thoughts will go toward simply repairing the appliance. While a professional will always see if repairs are possible first, it is vital to know when to cut your losses and know when it is time to get a new one.
1. It Needs Constant Repairs
Think of your furnace like a car. If you always need to repair certain components once every few months, then it is more cost-effective in the long run to simply get a new one. During the last couple of years in a furnace’s life, it will start breaking down much more frequently. When you need to contact a technician to come out once every few months, ask about getting a new one installed. You definitely do not want your furnace breaking down in the middle of winter.
2. It Is More Than 15 Years Old
Most furnaces are built to last between 15 and 20 years. Even if everything seems to be working fine, it may be best to replace it sooner rather than later. As furnaces get older, they become far less energy efficient. You do not want to deal with a faulty furnace for the last couple of years of its lifespan. It is best to simply invest in a new one once yours becomes 15 years old.
3. Your Energy Bills Increased
When your energy bills increase substantially, you need to look into the culprit. The answer could be any number of issues, but if nothing else seems to be causing problems, then you need to look toward your furnace. This is one issue you want to remedy right away. Many homeowners delay a new furnace installation because they are concerned about the cost. However, if you allow your electric bills to run out of control, then you could end up spending a lot more than the installation cost in the near future.
4. It Makes Strange Sounds
One telltale sign your furnace is on its last legs is that it will begin making odd noises. You may start hearing a banging, popping, or rattling sound coming from the furnace. These sounds could be a result of internal components becoming loose and banging around the inside of the unit. You need to be particularly mindful if these sounds are accompanied by a reduction in heat produced by the furnace.
5. There Is a Yellow Burner Flame
When a furnace works properly, it will produce a blue flame. However, when it begins to degrade, the blue flame will turn yellow. This is an extreme issue because a yellow flame indicates your furnace is producing carbon monoxide, a dangerous gas that can be fatal if too much is inhaled. There are various other signs that show your house has an excess of carbon monoxide, and they include:
- Rust forming on the pipes
- Presence of moisture on walls and windows
- Lack of any upward draft in the home’s chimney
- Streaks of soot form around the furnace
Any of these signs indicate that it is time to invest in a new furnace, but if several of them are present, then you absolutely need to get a new one. Any time you plan on installing a new furnace in your home, you want to leave the work to experienced professionals. It is dangerous to install a new furnace when you do not have any experience, so leave this work to the trained professionals. With a professional installation, you can be confident your new furnace will last for decades until you have to fuss with it again.
