Furnaces are typically out of sight and out of mind — right up until cold weather hits. At that point, homeowners hope their furnace is in good working order to help keep the house warm as temperatures drop. 

While it’s easy to adjust a thermostat, change batteries, and even change filters, there’s a lot more that goes into the process of making sure your furnace is safe and ready to use.

Part of good home maintenance is preparing your mechanical equipment for upcoming seasonal changes. When it comes to your furnace, it needs to be checked at least once every year, and several benefits are associated with such maintenance.

You will:

  • ensure your furnace is in peak performance.
  • decrease health risks.
  • prolong the system’s lifespan.
  • save energy.
  • prevent costly expenses down the road for emergency repairs or replacement. 

Some experts report up to 75 percent of no-heat calls in the winter are related to a lack of maintenance. 

And, it can be a health hazard. Technicians say a furnace checkup can reveal carbon monoxide leaks, which are hard to detect because the gas is colorless and odorless.

Carbon monoxide can lead to headaches, dizziness, nausea, and even death. An estimated 500 people die each year, and 15,000 people are taken to emergency rooms, due to carbon monoxide exposure. 

Furnace manufacturers recommend annual inspections as well as maintenance by a certified technician. Their warranty terms are clear about damage caused by improper or lack of maintenance.

Further, it is recommended that each side of your HVAC system get inspected and serviced once per year — air conditioning in spring and heating in the fall. 

A furnace tune-up can take between 90 minutes and two hours, and this mostly depends on the age of your furnace. 

You may be surprised to find just how much HVAC technicians can get done during this time. 

They inspect for safety issues as well as performance problems that can be addressed to help extend the life of the furnace by 20 to 40 percent and make it more energy efficient.  

Technicians will follow a checklist to cover all the important elements. 

Here are some things you can expect from a typical furnace inspection and cleaning:

  • Check thermostat settings to make sure the system is properly operating.
  • Inspect electrical connections and test voltage on the system components to prevent failure in the future.
  • Lubricate moving parts.
  • Inspect the condensate drain for obstruction.

Yes, an HVAC tune-up is well worth your time and money! Just like your car, the HVAC system is a complex piece of machinery full of critical and moving components that experience wear and tear over time. Your furnace gets considerable “mileage” each season. 

Be sure your home is warm and comfortable this winter by scheduling a furnace inspection.
