How To Change Your Furnace Filter (Trane Furnace)
Of all the DIY plumbing and HVAC tips out there, knowing how to change your furnace filter is one of the simplest, but most important. Depending on the quality of your filter, you may need to replace it every month. So here’s a step-by-step tutorial that will walk you through replacing your filter. (This will be especially useful for those with Trane furnaces.)
1. Get to know your furnace
Understanding the basic layout of your furnace will make it easier to change your furnace filter. It will also ensure you do it correctly. The filter is located near the air return. The direction of air flow moves from the air return to the air supply, which you will want to remember when you insert your new filter.
2. Get a clean filter
Make sure your replacement filter is the same size as your old one. You should find the dimensions labeled on the old filter. We’ve explored filter types in another post, but it’s worth repeating that pleated is more efficient than non-pleated. So if your old filter isn’t pleated, it’s worth the upgrade.
3. Turn off the furnace
Turn off the furnace before you replace the filter. Otherwise, unfiltered particles might enter the HVAC system, and would be putting your own safety at unnecessary risk.
You furnace likely has a switch located nearby. If your furnace doesn’t have a switch, simply lower your home’s thermostat.
4. Locate the filter rack
As illustrated in Step 1, the filter rack is located next to the air return. There is usually a lid or latch that you will need to open in order to access the old filter.
5. Remove the dirty filter
Removing the old filter is as easy as pulling it out of the furnace rack. Take note of the old filter’s size and orientation as you remove it! An arrow indicating the direction of air flow is usually located on the filter, which makes this step easy. The air flow should be directed toward the air supply.
6. Insert the clean filter
When you insert the clean filter, make sure the arrow indicating the direction of air flow is in the correct direction. Simply push the filter into the filter rack, and close the lid or latch.
7. Turn on the furnace
Turn the furnace back on — either by switch or thermostat, depending on your setup.
