Furnace Breakdowns – Frequently Asked Questions
How often should professional maintenance be scheduled?
Schedule a comprehensive tune-up at least once a year, ideally in early fall before the heating season begins.
What’s the number one cause of furnace breakdowns?
Dirty filters and lack of regular maintenance account for nearly 75% of preventable furnace failures.
Can I run my furnace without a filter temporarily?
Never operate your furnace without a filter – this can cause serious damage to your system and void your warranty.
Why does my furnace smell when I first turn it on?
A brief dusty smell is normal when first starting your furnace for the season, but it should dissipate within an hour.
How long should my furnace run in one cycle?
Typical cycles should last 10-15 minutes. Shorter or longer cycles might indicate efficiency issues.
What temperature should I set my thermostat to prevent problems?
Keep your thermostat between 68-72°F during the day and no lower than 65°F at night to maintain optimal system operation.
When should I consider replacing instead of repairing?
Consider replacement if your furnace is over 15 years old or if repair costs exceed 50% of a new unit’s price.
Emergency Preparation Tips For Furnace Breakdowns
Don’t wait until your furnace breaks down. Schedule you preventive furnace maintenance today and avoid those middle-of-the-night emergency calls.
Remember, in Clearwater’s climate, your furnace might not run as often as in northern states, but that makes regular maintenance even more critical. Sitting idle for months can lead to unexpected issues when you need heat the most.
