7 Tips for Avoiding Expensive Furnace Repairs

7 Tips for Avoiding Expensive Furnace Repairs

Furnace repairs can be expensive, which is one reason you want to avoid them. Also, serious comfort and safety issues, such as a warm, muggy home or a release of carbon monoxide, can precede them. Fortunately, there are ways to avoid a furnace repair that can cost thousands of dollars. Here are 7 tips to keep your furnace working smoothly and avoid serious damage or heater failure.

Some costly furnace repairs you can avoid include:

  • Ignitor ($150 to $500)
  • Gas valve ($200 to $600)
  • Blower motor ($150 to $2,000)
  • Draft inducer motor ($200 to $2,500)
  • Circuit board ($200 to $600)
  • Flue pipe ($400 to $800)
  • Combustion chamber ($100 to $600)
  • Heat exchanger ($100 to $1,500)
  • Coil ($600 to $2,000).¹

*These service costs depend on whether a component can be fixed or replaced.

Ways to Avoid Furnace Repairs

Your furnace may need fewer repairs and even last up to 20 years if you:

1. Keep Your Heating System Clean

Dust, dirt, and debris can collect on furnace components and cause them to malfunction. The effects can range from poor performance to overheating to a furnace shutdown. To start, regularly dust and vacuum your home so contaminants aren’t pulled through return vents into heating equipment. Also, your heating contractor should clean the furnace as preventative maintenance (you should keep clutter away from the unit as well). And every few years, schedule a ductwork cleaning to remove accumulated debris.

2. Change the Air Filter Often

Changing the air filter is a simple task. Just make sure you’ve purchased the same one or a filter compatible with your furnace. It should easily slide into its housing. Filters catch dust, lint, and other particles and debris that are floating in the air. If not captured, these can interfere with your heating system and reduce indoor air quality. By changing the filter every one to three months, you can help your furnace work less hard, so major repairs are less likely.

3. Keep Your Ductwork in Top Shape

Problems with ductwork can strain your furnace. If ducts are dirty, leak air, or are poorly designed, the unit may work much harder and less effectively. To avoid expensive furnace repairs, have a professional design and install ductwork. It should also be regularly inspected, cleaned, and, if necessary, sealed and repaired. 

4. Maintain an Optimal Indoor Temperature

Turning the thermostat way up won’t cool your home faster. Many people set it higher than necessary and turn it lower when they’re feeling too warm. To protect your furnace, try to find a comfortable medium so you can keep the thermostat at a stable temperature. It might not completely avoid repairs. However, it can increase the amount of time between them and increase the system’s operating life.

5. Keep the Thermostat Clean

A dusty thermostat may struggle to communicate with your furnace, causing it to be overworked. Periodically clean off the unit and make sure the wires are in good condition. If they’re loosely connected or frayed, they won’t send the right signals to your heating system. Your furnace may then turn on and off too frequently or run constantly, causing excess wear, increasing energy usage, and raising your utility bill.

6. Don’t Wait When Furnace Repairs Are Necessary

If your furnace makes strange, loud noises or releases foul odors, don’t hesitate to call a professional. A lack of heating, uneven temperatures around your home, or signs of rust or wear on the unit are not worth ignoring. The longer you wait, the more a repair is likely to cost. It can mean the difference between spending a couple hundred dollars to $1,000+.

7. Schedule Annual Furnace Tune-Ups

Hiring a professional to inspect your furnace, lubricate moving parts, and perform minor repairs as needed can help you save. These services should be included in your heating contractor’s maintenance plan. It’s a small investment when you consider furnace repair costs. To save money, schedule furnace maintenance at least once a year; it can prevent a minor issue from escalating to something more serious and expensive.
