Preparing your HVAC system for the fall season

Fall is right around the corner. As the leaves change colour and the air starts to cool down, it's time to shift your focus from cooling your home to heating it. A well-maintained HVAC system is crucial for staying comfortable during the colder months. Here's how you can get your system ready for fall:

Check and replace your air filter

The first step in preparing your HVAC system for the fall season is to check your air filter. Over the summer, your air filter has likely accumulated a lot of dust, pollen, and other debris. A dirty air filter can restrict airflow, making your system work harder than it needs to. This can lead to higher energy costs and potential damage.

Replacing the air filter is an easy task that you can do yourself. If it's dirty, swap it out for a new one. It's a small investment that can make a big difference in your HVAC system's performance. Depending on your home's conditions, you should replace the filter every one to three months or more frequently if you have pets, allergies, or other factors that contribute to increased dust and debris.

Inspect the furnace

Fall is when your furnace will start to see more use, so it's important to inspect it now. If your system has a pilot light, check to make sure it's burning a steady blue flame. A yellow or orange flame could indicate a problem with the gas or ventilation system.

Also, listen for any unusual noises when the furnace is running. Strange sounds like banging, rattling, or squealing could indicate a mechanical issue that needs addressing.

If you haven't done so in the past year, schedule a professional tune-up. A technician will inspect all the key components, clean the burners, and check the heat exchanger (a device that transfers heat from the combustion chamber to the air that circulates through your home) for cracks or other potential issues. This step is vital for both safety and efficiency.

If you find that your unit needs replacing, it's crucial to hire specialist to install furnace safely. Proper installation is key to ensuring the unit operates efficiently and safely, minimizing the risk of issues down the line.

Clean your vents and ducts

Dust and debris can also accumulate in your vents and ducts over time, especially after a busy summer of cooling your home. Dirty vents and ducts can reduce airflow and diminish air quality in your home, making your HVAC system less efficient.

Taking some time to clean your vents can help improve indoor air quality and ensure your system runs smoothly. You can use a vacuum with a hose attachment to reach into the ducts as far as possible. If you notice excessive dust buildup or suspect there might be mould or pests in the ducts, consider hiring a professional for a thorough cleaning.

Clean around your outdoor unit

If you have a heat pump or central air conditioning system, it's essential to check the outdoor unit. Over the summer, leaves, dirt, and debris can accumulate around it, which can impede airflow and reduce efficiency.

Start by turning off the power to the unit. Then, remove any debris from around the unit and gently clean the fins using a soft brush or hose. Be careful not to bend the fins, as this can restrict airflow.

Trimming back any vegetation within a reasonable distance of the unit, such as two to three feet, will also help maintain proper airflow. Keeping the area clear ensures that your system can operate efficiently during the fall and beyond.

Test your thermostat

Your thermostat plays a crucial role in the operation of your HVAC system. Before the weather gets cooler, test your thermostat to make sure it's functioning correctly. Set the temperature to a few degrees lower than the current room temperature and listen for the system to kick on.

If your thermostat is not responsive or the temperature readings seem off, it might be time to replace it. Consider upgrading to a programmable or smart thermostat, which can offer better control over your home's temperature and help save on energy costs.

Inspect and seal ductwork

Your ductwork plays a significant role in distributing warm or cool air throughout your home. However, leaks or gaps in the ductwork can cause significant energy loss, making your system work harder to maintain a comfortable temperature.

Walk through your home and check the visible ducts for any signs of damage, such as holes, gaps, or loose connections. You can use duct tape or mastic sealant to fix small leaks. However, if you notice extensive damage or if the ductwork is difficult to access, it's a good idea to call in a professional. Sealing your ductwork can improve your HVAC system's efficiency by up to 20 per cent, which translates to lower energy bills and a more comfortable home.

Conclusion

Preparing your HVAC system for the fall season doesn't have to be complicated, but it's crucial for maintaining a worry-free fall and winter season. By following these steps, you'll not only extend the life of your unit but also ensure it's ready to keep your home warm and cosy as the temperatures drop.
