Top 5 Furnace Repair Questions Homeowners in Coquitlam Ask

A reliable furnace is essential for keeping your home warm and comfortable during the colder months. But when something goes wrong, it can be frustrating and stressful. At Reliable Furnace Repair Coquitlam, we get many questions from homeowners about furnace issues. Here are the top five furnace repair questions and their answers to help you stay informed and prepared.
1. Why Is My Furnace Blowing Cold Air?
If your furnace is running but only blowing cold air, it could be due to:
- A thermostat issue – Make sure it’s set to “heat” and the fan is on “auto.”
- A clogged air filter – A dirty filter can restrict airflow and cause the furnace to overheat.
- A pilot light or ignition problem – Older furnaces have pilot lights that may need relighting.
If troubleshooting doesn’t work, it’s best to call a professional for furnace repair Coquitlam.
2. How Often Should I Replace My Furnace Filter?
You should replace your furnace filter every 1 to 3 months, depending on the type of filter and how often you use your heating system. A clean filter improves efficiency, extends your furnace’s lifespan, and helps maintain good indoor air quality.
3. Why Is My Furnace Making Strange Noises?
Unusual noises can be a sign of an underlying issue. Here’s what different sounds might mean:
- Banging or popping – Could be caused by dirty burners or expanding ductwork.
- Squealing – Often a sign of a worn-out belt or motor issue.
- Rattling – Loose parts or a broken component inside the furnace.
If your furnace is making loud or unusual sounds, it’s time to schedule furnace repair Coquitlam to prevent further damage.
4. What Should I Do If My Furnace Won’t Turn On?
If your furnace won’t start, try these steps before calling for service:
- Check the thermostat – Ensure it’s set correctly.
- Inspect the circuit breaker – A tripped breaker could be the issue.
- Replace the air filter – A clogged filter can shut down the system.
- If none of these steps work, you may have a more serious issue that requires professional repair.
5. How Do I Know If I Need a Furnace Repair or Replacement?
Most furnaces last 15 to 20 years, but if yours is breaking down frequently, making strange noises, or causing high energy bills, it might be time for a replacement. If repairs are becoming costly, upgrading to a new, energy-efficient furnace can save you money in the long run.
