Should You Repair Or Replace Your Furnace?

Construction & Contractors Blog

Unlike cars, furnaces are fairly simple machines. That's good. The simpler the machine, the less likely it is to break down or need repairs. However, because of this, when one part on a furnace goes bad, the rest of it is unlikely to work, too. So, how do you know when you should have your furnace repaired and when you should have it replaced? Read on to find out.

When To Repair

Furnaces operate on a fairly simple premise. Fuel is ignited in the burner. The burner produces heat, which it transfers to the heat exchanger. Cold air is removed from your home and fed across the heat exchanger. The air is then warmed up and fed back into your house.

Throughout this stage, any piece can become clogged, dirty, or less efficient. If you've had your furnace for 10 years or less, and it's starting to have problems, it probably just needs a cleaning or repairs. Sometimes the problems with your heating system don't always occur in the furnace either. That's why it's always best to hire a professional to inspect your system. Some typical problems include:

  • Ignition issues
  • Fuel line blockages or clogs
  • Dirty air filters
  • Improperly functioning blower motors
  • Malfunctioning or misreading thermostats

These are usually quick fixes that don't cost a lot to diagnose and repair and don't hurt your overall heating efficiency.

When To Replace

Most furnaces have life expectancy rates of 16 to 20 years. So, if you had a new one installed around the time one of your kids was born, and that same child is just about ready to leave high school, or already has, then any problems might be a sign that it's time to replace your furnace.

Also, similar to cars, the more problems a furnace has in a year, the more likely it is you'll need to replace it. One major concern is always the failure of the heat exchanger. These components are usually the most expensive part of the furnace, and, when they go out, it's time to consider a new unit.

Other signs that your furnace might need to be replaced include:

  • Rising heating costs (not based on real-world rises in heating prices, or colder winters)
  • Multiple parts needed replacement within a 1–3 year period
  • Yellow flames within the burner instead of blue
  • Rising carbon monoxide levels
  • Rattling and squealing noises

These are problems that signify your furnace is slowly worsening and will only get worse and can cause major health concerns. Contact a furnace repair company like Kohl Heating & Air Conditioning for more information.

All About Building a Home

Welcome to my website. I'm Albert Frost. Besides my dad, one of my biggest role models was my uncle Rick. He was a construction contractor who would let me come on his construction sites and also taught me everything he knew about building homes, including how to install hardwood flooring and add insulation. I always wanted to grow up to build houses like my uncle. I used to help my uncle with a lot of the grunt work needed to make a home a reality. But then I hurt my back playing football. Until I heal completely, I'm going to devote as much of my time as possible to teaching others about various construction topics I'm interested in.
