Particularly in the winter, a broken furnace may be a huge annoyance. While some issues require a professional, there are several furnace problems that homeowners can troubleshoot and fix on their own. Understanding when to attempt a repair and when to call an expert for furnace repair in Denver can save time and money.
1. Checking and Replacing the Air Filter
A blocked or dirty air filter is one of the most basic yet frequently ignored furnace problems. Airflow is restricted by a filthy filter, which increases system workload and increases the risk of overheating and shutdowns. To correct this:
- Turn off the furnace.
- Remove the filter and check for dust buildup.
- Replace it with a clean one if necessary.
The furnace’s lifespan is increased and efficiency is maintained by routinely changing the air filter (once in between 1 and 3 months).
2. Resetting the Thermostat
If your furnace isn’t turning on or maintaining the correct temperature, the thermostat may be the culprit. Before calling for furnace repair in Denver, try these steps:
- Make sure the “heat” mode is selected on the thermostat.
- Replace the batteries if it’s battery-operated.
- Verify that the temperature setting is suitable for the space.
Sometimes, a simple thermostat adjustment or reset can resolve heating issues.
3. Inspecting the Furnace Power Supply
A furnace that won’t start could have an issue with the power source. Homeowners should:
- Verify that the circuit breaker is on and hasn’t tripped.
- Check the furnace switch (usually located nearby) to make sure it’s set to “on.”
- Inspect the power cord for any damage.
If these steps don’t resolve the problem, there may be an internal electrical issue that requires a professional’s expertise.
4. Ensuring Proper Airflow
Blocked vents and registers can effectively prevent warm air from circulating. To ensure proper airflow:
- Keep vents open and free from obstructions.
- Vacuum dust and debris around vents.
- Check for visible blockages in ducts.
Proper airflow ensures even heating and prevents unnecessary strain on the furnace.
5. Reigniting the Pilot Light or Resetting the Ignition
Older gas furnaces use a pilot light, while newer models have electronic ignitions. If the furnace isn’t heating:
- Locate the pilot light and relight it following the manufacturer’s instructions.
- If the unit has an electronic ignition, try resetting it by turning the furnace off and back on.
If the pilot light won’t stay lit or the ignition continues to fail, professional furnace repair in Denver may be required.
6. Cleaning the Flame Sensor
A dirty flame sensor can prevent the furnace from staying on. This safety device shuts down the system if no flame is detected. To clean it:
- Turn off the furnace and locate the flame sensor (usually near the burners).
- Remove it using a screwdriver.
- Gently clean it with fine-grit sandpaper or a soft cloth.
- Reinstall the sensor and restart the furnace.
A properly functioning flame sensor ensures the furnace operates safely and efficiently.
When to Call a Professional
While some furnace issues are easy to fix, others require expert attention. Call a professional for furnace repair in Denver if you experience:
- Unusual noises like banging or screeching.
- A persistent gas smell, which could indicate a leak.
- Repeated system shutdowns or a furnace that won’t turn on.
- No heat production despite troubleshooting efforts.
Attempting to fix complex issues, such as gas leaks or major electrical failures, without proper training can be dangerous. In these cases, hiring a certified technician is the safest option.
Conclusion
Knowing how to handle minor furnace repairs can save money and keep your home warm during the winter. Regular maintenance, like changing filters and ensuring proper airflow, helps prevent major problems. However, when issues persist or involve safety risks, calling a professional for furnace repair in Denver is the best course of action.
By understanding what you can fix and recognizing when to seek expert help, you can keep your furnace running efficiently and avoid costly breakdowns.
