Determining whether your furnace needs repair or replacement depends on factors such as age, efficiency, and the extent of the issue. Generally, you should consider repairs if:

• The furnace is less than 10–15 years old.
• Repairs cost less than 50% of the replacement cost.
• Issues are isolated, such as a malfunctioning thermostat or clog in the blower.

However, furnaces older than 15 years with frequent breakdowns may be better candidates for replacement.

Strange noises from your furnace often indicate underlying problems:

• Banging or popping sounds: This could be due to delayed ignition or duct expansion.
• Squealing: A worn-out fan belt or motor could be the cause.
• Rattling: Loose panels or components might need securing.

If you hear unusual noises, it’s best to schedule an inspection promptly to prevent further damage or safety risks.
