Is Your Furnace Telling You It's Time for Attention?

Your furnace is one of the most important appliances in your Calgary home, especially during our harsh winters. Recognizing the warning signs of a failing furnace can help you avoid an unexpected breakdown on the coldest night of the year.

Warning Signs to Watch For

1. Age of Your Furnace

Most furnaces have a lifespan of 15-20 years. If your furnace is approaching or exceeding this age, it's time to start planning for a replacement, even if it's still running.

2. Rising Energy Bills

If your heating bills have been steadily increasing without a corresponding increase in usage, your furnace is likely losing efficiency.

3. Frequent Repairs

If you're calling for repairs more than once a year, those costs add up quickly. A good rule: if repair cost exceeds 50% of a new furnace cost, replacement is better.

4. Uneven Heating

Some rooms too hot while others are too cold? This could indicate your furnace is struggling to distribute heat evenly throughout your home.

5. Strange Noises

Banging, popping, rattling, or squealing noises often indicate mechanical problems. Persistent noises in an older furnace suggest worn components.

6. Yellow Pilot Light

A healthy furnace flame should be blue. A yellow or flickering flame could indicate carbon monoxide issues - a serious safety concern requiring immediate attention.
