As the sun sets on summer and cooler days of fall arrive in Los Angeles, it’s the perfect time to check in on your HVAC system. Regular maintenance not only keeps your home comfortable but can also lead to significant savings. In fact, performing seasonal maintenance can save homeowners up to 30% on energy bills. This fall HVAC maintenance checklist will help you prepare your system for the changing temperatures and ensure optimal performance throughout the season.
Why Seasonal HVAC Maintenance is Important
Seasonal HVAC maintenance is crucial for several reasons. Regular upkeep boosts efficiency, reduces energy costs, and helps prevent unexpected breakdowns. According to the US Department of Energy, neglected systems can lose up to 5% of their efficiency each year. By investing time in seasonal maintenance, you can enjoy a healthier living space, improved air quality, and increased system longevity.
Inspect and Replace Air Filters
Inspecting and replacing air filters is one of the simplest tasks that can have a huge impact on your HVAC system.
Find the air filter compartment in your HVAC system.
Examine the filter; replace it if it's dirty or discolored.
For optimal results, replace or clean your filter every 30 to 90 days, depending on how frequently you use your system and the air quality in your area.

Changing or cleaning air filters can lead to up to 15% improved efficiency in your HVAC system.
Check Thermostat Settings
Next, adjusting your thermostat settings is essential as fall temperatures drop.
Ensure your thermostat is set to “Heat” mode, if your model allows.
Set the temperature to a comfortable level, such as 68°F.
If you don’t have one yet, consider investing in a programmable or smart thermostat, which can save you around 10% on your heating bills.
Regular adjustments help maintain comfort while optimizing your system's energy consumption.
Clean the Condenser Unit
Cleaning your HVAC condenser unit supports its efficiency and longevity.
Turn off the power to the unit before starting.
Clear away any debris, dirt, or leaves surrounding the unit's exterior.
Use a garden hose to gently wash the fins. Avoid pressure washers as they can damage delicate components.
Keeping the condenser unit clean can prevent overheating, which can ultimately save you costly repairs.
Inspect Ductwork for Air Leaks
Leaky ducts can lead to inefficient heating and increased energy costs.
Look for visible signs of damage in ductwork.
Use duct tape or mastic sealant for minor repairs.
For significant issues, consider hiring a professional technician to address the problem.
Sealing duct leaks can enhance your home’s energy efficiency by up to 20%, while also improving indoor air quality.
Schedule a Professional Inspection
While many tasks can be handled on your own, a professional inspection is invaluable.
Search for HVAC technicians with solid reviews in your area.
During the inspection, the technician will check all components and identify potential issues.
You might also schedule a fall HVAC tune-up, ensuring everything is ready for winter.
These inspections can reveal hidden problems and provide reassurance that your system is functioning optimally.
Clear the Area Around the Unit
It’s important to keep the area around your outdoor HVAC unit clear for better airflow.
Remove any overgrown branches, bushes, or debris close to the unit.
Aim to maintain at least a two-foot radius around the unit, allowing for unrestricted airflow.
Regularly check this space, especially in fall when leaves accumulate.
Clearing this space can prevent airflow issues, allowing your system to run more efficiently.
Test Your Heating System
Testing your heating system before colder weather hits ensures everything is working correctly.
Activate your heating system and listen for any unusual noises.
Check to see that warm air flows from the vents in every room.
If there are any issues, consult a professional for assistance.
Early testing helps you catch and resolve issues, ensuring you have reliable heating when you need it.
Prepare for Winter
As we move from autumn to winter, preparing your home is essential for comfort and efficiency.
Seal cracks and gaps in windows and doors to reduce heat loss.
Insulate exposed plumbing pipes, especially in unheated spaces.
Close vents in rooms you rarely use, which can help save energy.
Taking these steps helps your HVAC system work less and save energy, leading to lower bills.
