Common Causes Of An Upstairs Furnace Not Working
Furnace issues can disrupt your comfort quickly. Understanding the common causes can help you identify and resolve problems efficiently.
Electrical Issues
Electrical problems often cause furnaces to malfunction. Check the following:
- Power Source: Ensure the furnace is connected to a working power outlet. A tripped circuit breaker or blown fuse can cut power.
- Wiring: Inspect wiring for frayed or damaged areas. Faulty wiring can prevent the furnace from receiving power and functioning properly.
Thermostat Problems
Thermostats control the temperature and operation of your furnace. Problems can arise from:
- Incorrect Settings: Verify that the thermostat is set to heat mode and the temperature setting is appropriate.
- Malfunctioning Thermostat: If adjustments don’t impact the furnace, consider replacing the thermostat. A faulty thermostat may not signal the furnace to operate.
- Frequency of Replacement: Replace filters every 1-3 months. Clogged filters restrict airflow, leading to overheating and potential shutdowns.
- Cleaning: If filters are reusable, clean them according to the manufacturer’s instructions to maintain airflow and efficiency. Dirty filters can also lead to higher energy costs.
Troubleshooting Steps
When your upstairs furnace isn’t working, follow these troubleshooting steps to identify and resolve the issue effectively.
Check Power Supply
- Confirm Power Connection: Ensure the furnace is plugged in or connected to its power source. Inspect any circuit breakers or fuses related to the furnace; if they are tripped or blown, reset or replace them.
- Inspect Wiring: Look for signs of damaged or frayed wires. If you find any, contact a qualified technician for repair or replacement to ensure safety.
- Turn on the Switch: Some furnaces have an on/off switch, often located near the unit. Make sure it’s in the ‘on’ position.
Inspect Thermostat Settings
- Check the Mode: Ensure the thermostat is set to ‘heat’ instead of ‘cool’ or ‘off’. Misconfigurations can prevent the furnace from activating.
- Adjust Temperature: Raise the thermostat setting above the current room temperature. If the furnace doesn’t start, the thermostat might be faulty.
- Replace Batteries: If your thermostat runs on batteries, replace them to avoid power issues that could affect its performance.
- Locate the Filter: Find the access panel of your furnace and locate the air filter. It typically slides in and out easily.
- Inspect Filter Condition: Check for dirt accumulation or damage. A clogged filter restricts airflow, causing the furnace to work harder and potentially shut down.
- Replace or Clean Filter: If the filter looks dirty, either replace it or clean it according to the manufacturer’s instructions. Ideally, you should replace filters every 1-3 months to maintain optimal airflow.
By systematically following these steps, you can pinpoint and potentially resolve issues with your upstairs furnace efficiently.
When To Call A Professional
Sometimes, troubleshooting your upstairs furnace isn’t enough, and you’ll require professional assistance. Recognizing the right time to call for help can save you time and ensure safety.
Signs You Need Help
- Unusual Noises: Listen for banging, clanking, or hissing sounds. These signals often indicate mechanical problems requiring expert attention.
- Persistent Smells: Detecting strong gas or burning smells often signifies a potentially hazardous situation. Leave the area immediately and contact a professional.
- Inconsistent Heating: If certain rooms remain cold despite adjustments, your system may have a more significant issue that an expert needs to address.
- Frequent Cycling: A furnace that repeatedly turns on and off may indicate malfunctioning components that require replacement.
- Check Credentials: Confirm the technician is licensed and insured. This ensures they are qualified to handle your specific furnace issues.
- Read Reviews: Look for customer reviews and ratings online. Experienced technicians often have a track record of reliability and customer satisfaction.
- Get Estimates: Request quotes from multiple technicians. Comparing estimates helps you find a fair price and understand the scope of work needed.

Preventative Maintenance Tips
You can keep your upstairs furnace running smoothly with proper preventative maintenance. Regular checks and replacements play a crucial role in enhancing the efficiency and lifespan of your unit.
Regular Filter Replacement
Replace your air filter every 1-3 months to maintain optimal airflow. A clogged filter can restrict airflow, making your furnace work harder and leading to breakdowns. Use the following steps for filter replacement:
- Turn off the furnace.
- Locate the air filter compartment, typically near the blower.
- Remove the old filter and inspect it for dirt and damage.
- Insert a new filter, ensuring it’s oriented correctly.
- Turn the furnace back on and check for normal operation.
Annual Maintenance Checks
Schedule annual maintenance checks for your furnace. These inspections help identify potential issues before they become major problems. During the maintenance check, a technician typically performs these tasks:
- Cleans the furnace components.
- Checks the electrical connections.
- Inspects and lubricates moving parts.
- Tests the thermostat for accurate readings.
- Evaluates overall system performance.
By investing in annual maintenance, you enhance the reliability of your heating system and improve indoor comfort during colder months.
