How to Locate Your Furnace Filters

Air Filter Located Behind Return Grills
AC Filters are often located on the wall behind a return grill. If your filters are located in the return grill you may have multiple air filters to replace. Locate all of the return grills in the house. You may also have different size filters in each return. Don't assume they are all the same size. Check before ordering your filters.
Sometimes you can see the filter behind the return grill. If the return grill has filters, it probably has a latch instead of screws. The latch can be on the top, side or bottom of the grill depending on how it was installed. The image below has a 2 latches on the bottom that swing out to unlock and open the grill.
Pull down on latches to open the grill and replace the AC filter. be careful when removing the grill that the whole grill doses not fall. It is a good idea to hold the grill securely when opening.

Most thermostat controls have a setting to reset the filter. This will create an alert or reminder on the control, usually at a set period such as, 3 months, when it is time to change your filter.
On this control the filter reset is on the bottom left in the red box. Pressing the filter button resets the filter alarm so you will receive a warning on the display when it is time to change the filter. Setting a filter subscription is another good way to make sure you change your filters when it is time to properly maintain your system.
Expert Tip: Put FAN ON LOW to Maintain AIR QUALITY
There are a few benefits of continuously running the fan on an HVAC system, including:
- Improved Indoor Air Quality: Running the fan continuously can help to circulate air and remove impurities, such as pollen, dust, and pet dander, resulting in improved indoor air quality.
- Increased Comfort: Running the fan continuously can help to distribute cool or warm air throughout the home, resulting in more consistent temperatures and increased comfort.
- Enhanced Energy Efficiency: Running the fan continuously can help to reduce the load on the HVAC system, potentially reducing the amount of energy required to heat or cool the home.
- Improved Humidity Control: Running the fan continuously can help to control humidity levels in the home, preventing mold and mildew growth, and promoting overall comfort.
Evenly Distribute Air Through Out the Home
When the fan is running it does not take the home as long to heat up or cool down as when the fan is not running. When a fan is running, it helps to distribute the air generated by the HVAC system more evenly throughout the space, which can allow the temperature to reach the desired level more quickly. This means that the HVAC system doesn't have to run as long to achieve the desired temperature, which can help to reduce the amount of energy consumed.
By circulating the air, the fan can also help to reduce hot and cold spots in the home, which can make the environment more comfortable. This can be especially beneficial in homes with poorly insulated rooms or high ceilings, where it can be difficult to maintain a consistent temperature.
Energy Consumption
It's important to note that running a fan continuously can also consume energy, so it's not just about the reduction of energy consumption by the HVAC system. However, in many cases, the energy saved by the HVAC system can outweigh the energy consumed by the fan, leading to overall increased energy efficiency.
** It's important to note that the benefits of continuously running the fan can vary depending on the HVAC system and the home's specific needs. Before making the decision to run the fan continuously, it is recommended to consult with a professional to determine the best course of action for your specific HVAC system and home.
