DIY Furnace Repairs: What You Can Do Versus When To Call a Technician
When your furnace stops working during cold winters, it’s tempting to try and fix the issue yourself to save money. While some maintenance tasks are perfectly safe and effective to handle on your own, more complex repairs should always be left to the professionals. Attempting advanced DIY furnace repairs can lead to dangerous situations, voided warranties – or even a complete system failure.
In this guide, Peppy Heating & Cooling outlines tasks homeowners can safely tackle, common troubleshooting tips, and clear indicators that it’s time to call an HVAC expert.
Safe DIY Furnace Tasks You Can Handle at Home
Most DIY furnace repairs revolve around basic maintenance tasks that can improve efficiency and reduce the risk of costly breakdowns. These steps can often resolve minor issues and extend the lifespan of your heating system.
1. Replace the Air Filter
Changing the air filter is the easiest and most impactful task you can do. A clogged filter restricts airflow, forcing your furnace to work harder and increasing your energy bills. Aim to replace the filter every 1-3 months, depending on usage and filter type.
2. Clean Furnace Components
Dust and debris can collect in and around your furnace, impacting performance. Use a vacuum with attachments to clean vents, registers, and around the furnace housing. For extra cleaning, gently wipe accessible components with a soft cloth or brush.
3. Inspect the Thermostat
Ensure your thermostat is set to “eat” mode and that the temperature setting is above room temperature. Replace the batteries if needed and check for dust buildup that could interfere with its operation.
4. Check the Power Source
Verify the furnace is receiving power. Reset tripped circuit breakers and ensure the power switch near the unit is in the “on” position. For gas furnaces, check that the gas valve is open and the pilot light is lit.
Tools Every Homeowner Needs for Furnace Maintenance
Stock your toolkit with these essentials for safe and effective furnace maintenance:
- A digital thermometer for checking air temperature.
- A screwdriver set for accessing panels and components.
- A vacuum with attachments to clean vents, registers, and surrounding areas.
- Replacement air filters
- A wire brush for cleaning burners.
- A flashlight to inspect hard-to-see areas.
- Safety gloves and a dust mask to protect yourself.
When To Call an HVAC Professional
While basic maintenance and troubleshooting can solve some problems, certain situations require professional expertise to avoid injury, further damage, or safety risks.
Contact a licensed HVAC technician if you encounter any of the following:
- Gas odors or carbon monoxide alerts. These are serious hazards that require immediate professional attention.
- Electrical issues or burning smells, AKA signs of wiring problems or overheating components.
- Strange noises, like grinding, squealing, or banging, that can indicate mechanical failures.
- Frequent cycling. If the furnace is turning on and off rapidly, it could mean a failing thermostat, clogged filter, or other issues.
- Yellow or flickering pilot light may point to ventilation or gas issues.
- No heat despite troubleshooting. If basic steps don’t resolve the issues, it’s time to call a technician.
- Unusually high energy bills. This could signal that your furnace is working harder than necessary due to inefficiencies.
Furnace Maintenance Tips to Prevent Repairs
Regular maintenance is key to avoiding unexpected breakdowns and costly repairs. Be sure that you’re scheduling your annual inspections before the major seasons to ensure your system is in peak condition.
Additionally, you’ll want to:
- Keep vents and registers clear of obstructions.
- Seal air leaks in ductwork to improve efficiency.
- Monitor your system for unusual changes in performance.
