Many homeowners do not regularly monitor their heating system. Especially if it is still working. They assume everything is fine. However, a furnace might break down unexpectedly. This mostly happens due to negligence.
Luckily, there is a way to avoid such inconveniences. Read on to learn more!
Check the filter
A clogged filter:
- Limits the airflow
- Overworks the motor
- Reduces heat transfer.
Restricted airflow can cause overheating and system shutdown.
You should:
- Check the filter after every 30-90 days.
- Change filters that are not reusable.
- Clean reusable filters.
Inspect the thermostat
Poor thermostat operation is risky. It can lead to:
- A short-cycling effect
- Uneven heating
- System shutdown.
The thermostat should be well adjusted. Do this as well:
- Test the temperature with a different thermometer.
- Change batteries (where necessary).
- Suppose your furnace is not efficient; consider upgrading to a programmable one.
Check the blower assembly
This component circulates warm air in your house. Monitor this:
- Odd sounds. For example, grinding and squealing
- Dust accumulation on fan blades.
- Cracks on belts (where applicable).
A faulty blower decreases the heating capacity. Suppose you notice any motor-related issues. In that case, seek a professional furnace repair service.
Examine the heat exchanger
This is an important element of safety. Check whether there is any sign of:
- Cracks
- Corrosion
- Damage
- Soot buildup.
Cracks are very dangerous. They may cause gas leaks. In such a case, call a licensed technician. They are the most qualified for this inspection.
Clean the vents
Dirty ducts will obstruct air. That decreases system efficiency. It also strains internal components.
Ensure that:
- The supply and return vents are clear.
- No dust buildup.
- Dampers are stable and free.
Test the ignition system
The new furnaces operate with electronic firing. The old ones, possibly with pilot lighting. Problems with ignition may cause safety issues.
Make sure that:
- The pilot flame is stable. It should be blue.
- Electronic igniters turn on immediately.
Check burner flames and gas connections
If you have a gas furnace:
- Test the air for a gas smell. Vacate immediately if present.
- Check the flames. They must be even and blue.
- Clean dust and debris off burners.
Flickering or yellow fires can be a sign of burning issues.
Clean the condensate drain
Obstructed drains may cause system failure. Check the drain line. It should not be clogged. Notice condensation? Clean the part with water. You can also use a mild cleaner.
Schedule annual professional maintenance
Finally, professional maintenance is a must.
An expert furnace technician will:
- Test system efficiency.
- Check electrical connections.
- Measure gas pressure.
- Perform safety diagnostics.
- Address any issues.
Servicing on a yearly basis prolongs equipment service life. This will minimize any chance of an emergency breakdown.
