Five Signs Your Furnace Need to be Replaced

There’s nothing worse than waking up in the middle of the night to a freezing cold house. If you’ve ever had your furnace break down or malfunction, you know how miserable it can be to suffer through the cold temperatures while waiting for a repair or replacement. If only you could diagnose a furnace that will soon fail and need replacement before it happens! Luckily, the furnace repair and replacement experts at Carey and Walsh have put together a list of the warning signs to look out for that your furnace may soon break down.


1. Colder Temperatures Than Normal

If your furnace is blowing cold air, obviously there is some kind of problem with the heating mechanism. This could be caused by a number of different problems including, the heat exchanger, pilot light, and fan motor. If you notice cold spots in different areas throughout your home, the furnace is likely having trouble blowing the air to the furthest spots from an air vent. If there is no cold air coming out of the vents at all, the problem is probably with your pilot light or heat exchanger. All of these problems are complex and should be looked at by a certified HVAC technician like those at Carey and Walsh.


2. Strange Noises

It is normal for your furnace to make some noise. However, there are some noises that should make you consider calling a technician. If you hear excessive banging, rattling, or popping, there is probably a problem with at least one of the components of your heating system. Another noise to watch out for is constant cycling. If your furnace is turning on and off more frequently than normal, it’s an indication that it may need to be repaired or replaced. This can be caused by many different problems so be sure to call a heating expert who can diagnose the problem for you.


3. Increased Heating Bill

If you have noticed you heating bill skyrocket without any equivalent increase in use, there is probably an issue with your system. Even if you have seen your bill creep slowly upward, there may be a problem that is causing your heating system to run less efficiently. It’s possible that the only problem with your furnace may be a clogged air filter or something similarly easy to fix. However, when a larger problem exists, a replacement =may be more cost effective than repairing the issue.


4. Furnace is Older Than 15 Years

The typical lifespan of a furnace is about 15-20 years. As long as you have had proper maintenance and cleaning performed on your unit and it is under 15 years of age, you probably don’t have to worry about it breaking down or needing a replacement. However, if it is older than 15 years, You should probably start paying attention to any strange activity or behavior from it. Your heating system could be ready to give out at any time, and it is better to replace your furnace before you absolutely have to!


5. Yellow Pilot Light

A normal pilot light color flame is a consistent, bright blue. If your flame turns yellow or starts flickering, there is an issue with your pilot light. This is a sign that your burner is producing dangerous carbon monoxide. If you notice a yellow light, flickering, condensation, rotten egg smell, or rust, turn off your furnace immediately and call a technician from Carey and Walsh.
