Prepare Your HVAC System for Fall: Essential Maintenance Tips

 As fall approaches, with cooler days and crisper air, it's the ideal time to ensure your HVAC system is

in top condition for the coming months. Regular maintenance is key to keeping your system running efficiently, prolonging its lifespan, and avoiding unexpected breakdowns. 

At Lockhart Industries Ltd. in Duncan, BC, we’ve put together a comprehensive guide to help you prepare your HVAC system for the fall.

1. Regularly Replace and Clean Air Filters 

Air filters are vital for maintaining indoor air quality and ensuring your HVAC system operates smoothly. When filters become clogged with dust and debris, the system has to work harder, increasing energy costs and leading to potential damage. To keep your HVAC system in peak condition:

• Replace air filters every 30-90 days.
• Check filters more frequently if you have pets or live in a dusty area.
• Lightly vacuum filters if they’re only slightly dirty to extend their life.

2. Clear Debris from the Outdoor Unit 

Your HVAC system's outdoor unit is exposed to the elements, making it susceptible to debris buildup from leaves, grass clippings, and snow. Regularly clearing the area around the unit helps maintain proper airflow and prevents potential damage. Here’s what you should do:

• Inspect and clear debris from the unit on a weekly basis.
• After storms or windy days, check for and remove fallen leaves and branches.
• In winter, remove snow and ice buildup around the unit.
• Always turn off the unit and wear gloves before performing any cleaning.

3. Inspect the AC Drain Pipe 

The AC drain pipe is responsible for removing condensation from your HVAC system. Clogging can cause water damage, mould growth, and system malfunctions if it becomes clogged. To prevent these issues:

• Turn off your HVAC system before inspecting the drain pipe.
• Check the drain pan for standing water and clean it to prevent mould.
• Use a garden hose or shop vac to clear any blockages in the drain pipe.
• Pour distilled vinegar down the drain pipe to keep it free from clogs.

4. Clean Indoor Vents and Registers 

Proper airflow is essential for your HVAC system to work efficiently, and this includes keeping your indoor vents and registers clean. Dust, pet hair, and other debris can obstruct airflow and reduce system efficiency. To ensure smooth operation:

• Regularly dust and vacuum around vents and registers.
• Move any furniture that may be blocking airflow.
• Use a vacuum brush attachment to clean inside vents thoroughly.

5. Maintain Your HVAC Humidifier 

If your HVAC system includes a humidifier, fall is a good time to perform maintenance to ensure it’s ready for the dry winter months. Proper care of your humidifier can improve indoor air quality and prevent discomfort caused by dry air. Follow these steps:

• Turn off the water supply to the humidifier.
• Replace the humidifier pad to prevent clogging from mineral deposits.
• Adjust the humidity setting to a comfortable level between 35-45%.
• Turn the water supply back on once the maintenance is complete.

6. Monitor Refrigerant Levels 

Refrigerant is crucial for your HVAC system’s cooling function. A low refrigerant level may indicate a leak, leading to poor performance and costly repairs. To avoid issues:

• Listen for unusual noises or observe any changes in system performance.
• If you suspect a refrigerant leak, contact a professional technician to inspect and repair the system promptly.

7. Listen for Unusual Noises 

Just like a car, your HVAC system may give early warning signs through unusual noises. These sounds often indicate a problem that needs attention. If you hear something unusual, don’t ignore it—start troubleshooting:

• Investigate airflow blockages or loose items in vents.
• If you can’t identify the source of the noise, call a professional to investigate.

Taking care of your HVAC system before the cold weather hits is crucial for ensuring a warm and comfortable home throughout the fall and winter. By following these maintenance tips, you can prevent costly repairs and extend the life of your system. However, some tasks are best handled by professionals to ensure your system is functioning at its best.
