There will come a time as a homeowner where your furnace is going to break down, sometimes it can be repaired affordably or might just be time for a new.  But how to know when you need a new furnace is the tricky part.  Here are some of the signs that it is going to be time to replace your furnace and get something that will be more energy efficient and far fewer repair costs.

If your furnace is more than 15 years old

The life expectancy of the average furnace is about 18 years, but if it is more than 15 years old then you should get an ENERGY STAR rated furnace which is far more efficient than what you have now.  The new furnace will save you lots on your energy costs.

Your heating bill is through the roof

There are a number of reasons that your heating bill may be higher than normal, but if you have already had furnace repairs done and you know for sure that the air ducts have been spilled then spikes in heating costs shouldn’t happen.  The increased energy consumption could be from your furnace having to work harder.

Too many repairs

Your furnace will need the most repairs done at the end of its life, very similar to fixing an older car over and over.  In the last two years if you have had an HVAC company in more than three times it is time to look at a new furnace.

Your furnace is too loud

If you turn on your furnace and you hear popping, banging or any other weird noises then it is time to replace.  You may also notice that the blower turns off too frequently or it blows out cold air.  That means it is time to bring in a professional company to replace the unit.

The flame is yellow rather than blue

When the flame is yellow that means that your furnace is producing carbon monoxide which is dangerous.  Carbon monoxide has no smell, no taste and it can be fatal to your family.  That is why you need to have a carbon monoxide detector in your home along with a smoke detector.

Replacing your furnace is never fun and no homeowner wants to have to do it, but your furnace won’t live forever.  If it is costing too much to repair or your heating bills are skyrocketing then it is time to bite the bullet and get a new furnace.
