Here are the 8 Furnace Warning signs that suggest you need a furnace replacement.
1. How old is your furnace model?
A better strategy to start is to check the furnace age and compare it to the national average. On average you can expect a home furnace to last anywhere between sixteen to twenty years. If your home furnace is nearing the average age, you need to look for replacement options. It is better to plan the replacement like most homeowners, so you get the time to look out for the best model. Stalling the replacement will result in a malfunction and will cause you to panic where searching for a replacement will become a worrisome activity for you to manage. Check your furnace to search for the pilot light. If you locate one, it is a sure confirmation that your model is likely an old one that has been running for over 25 years.
2. Observing an Increase in Gas & Electricity Bills?
A rise in your bills may not be the result of the increase in tariff of gas and electricity prices. When your furnace is old, it may end up consuming more energy bringing down its efficiency and mounting the extra charges on the utility bills. The old furnace will run longer, expend more energy and will cause your bills to go up. The additional amount you will save if you buy a new furnace system will make up for this necessary investment.
3. Any Furnace Servicing in the last two years?
Just like a car, your furnace will need replacement of parts as it ages. If the part replacements are frequent, it means that you are losing good money to replace the old parts and keep the furnace running. It is typical for the furnace unit to breakdown and brings you major replacement problems in the last two years of their functioning lives. Another way to assess the situation is the waiting time you have to endure to find the right part for replacement. The older the furnace is, the more difficult it is for you to find the replacement parts. On a cold and freezing night, this waiting period will bring you much annoyance and dismay.
4. Does your thermostat function at an optimal level to your satisfaction?
Do you feel that temperatures are uneven in your rooms? While some places in the house are cold and others are hot? Are you stuck adjusting your thermostat frequently with no results? These indicators suggest that your furnace lacks the power to distribute the air evenly in your house to maintain a comfortable temperature in all rooms.
5. Is the burner flame in yellow color instead of the blue color?

Another sound is the furnace blower operating excessively. Do the fan starts and stops continuously or does it flow cold air seldom?

7. How are you and your family feeling recently?
The furnace may get cracks inside the heat exchanger when it gets old. Such breaks can let carbon monoxide leak in your house.
