Furnace maintenance and cleaning

Getting your furnace ready for winter is essential to ensure your home stays warm and comfortable during the colder months. Here are the steps you can follow to prepare your furnace:

1. Schedule a Professional Inspection:

It’s a good idea to start by scheduling an annual furnace inspection and maintenance service with a qualified HVAC technician. They will perform a thorough check to identify and address any issues, ensuring your furnace operates efficiently and safely throughout the winter.

2. Change or Clean the Furnace Air Filters:

Replace or clean the air filters in your furnace. Dirty filters can restrict airflow, reduce efficiency, and potentially lead to costly breakdowns. Depending on the type of filter you have, you may need to replace it every 1-3 months.

3. Check the Thermostat:

Make sure your thermostat is working properly. Test it to ensure it can accurately control the temperature in your home. You may also want to consider upgrading to a programmable or smart thermostat for more efficient heating control.

4. Inspect the Vents and Ducts::

Check all the vents and ducts in your home for obstructions, such as furniture, curtains, or other items that may block airflow. Clean vents and registers to ensure proper circulation.

5. Clear the Area Around the Furnace:

Remove any clutter or obstructions from the area around your furnace. Ensure there is enough space for proper ventilation, and nothing is blocking access to the furnace.

6. Test the Ignition and Safety Controls:

During the professional inspection, the technician will check the ignition system and safety controls to ensure they are working correctly. Do not attempt to do this yourself, as it involves potentially dangerous components.

7. Check for Gas Leaks (if applicable):

If your furnace runs on natural gas or propane, have a professional check for gas leaks and ensure that all gas connections are secure. Safety is paramount when dealing with gas appliances.

8. Lubricate Moving Parts:

Some furnaces have moving parts that require lubrication. Consult your furnace’s owner’s manual or ask a technician if lubrication is necessary.

9. Test the Blower Motor:

Test the blower motor to ensure it’s functioning correctly. If you notice any unusual noises or a lack of airflow, contact a professional technician for further inspection.

10. Replace Batteries:

If your thermostat or carbon monoxide detector requires batteries, replace them to ensure they function correctly throughout the winter.

11. Consider a Carbon Monoxide Detector:

Ensure you have a functioning carbon monoxide detector installed near your furnace to alert you to any potentially dangerous carbon monoxide leaks.

12. Stock Up on Filters and Necessary Supplies:

Purchase replacement air filters, and have any necessary supplies or spare parts on hand in case of an emergency. This includes extra furnace filters, spare fuses, and the contact information for a reliable HVAC technician.

By following these steps and scheduling professional maintenance, you can help ensure that your furnace operates efficiently and safely throughout the winter, keeping your home warm and comfortable. Contact Doyle Home Services today to schedule your annual furnace clean and service.
