The older the furnace, the more likely it becomes to let you down. Then again, it wasn’t designed or built to last forever. The average lifespan of a furnace is 12 – 15 years. Furnace Repair  With proper care and maintenance, it can last longer.  On the other hand, and without regular maintenance, it might not make it to its 12th birthday. Still, if you live in your home long enough, you’ll need to replace it.  Is that time now?  It could be if you notice any of the following warning signs. I Repair or Replace My Furnace Large increases in heating costs If your heating bills are significantly higher than normal, maybe all it needs is a good cleaning.  But, if it’s up there in years, built up wear and tear can be the cause.  There’s no way to tell for sure without a professional system diagnosis. Noisy Operation Any number of things can cause your furnace to make loud, unappealing noises.  If you hear banging, chances are there’s something wrong with your fan assembly.  A popping or wheezing noise indicates a problem with air distribution.  These are likely repairable issues.  Cracked Heat Exchanger A cracked heat exchanger indicates a possible carbon monoxide leak, and that can spell big trouble. If your heat exchanger is cracked and up there in years, this is a great time to replace it.  The cost of the repair will likely not be worth it. Frequent On and Off Cycling Frequent system cycling indicates one of a few possibilities:  a clogged filter, improper airflow, or a problem with your thermostat. These are usually simple repair jobs.
