Replacing the air filter in your home or office is an important task that can help improve air quality, reduce energy costs, and extend the life of your heating and cooling system. To make it easier, we've put together a step-by-step guide on how to replace an HVAC filter. First, turn off the HVAC unit and remove the access panels to reach the filter. Then, take out the old HVAC filter and insert the new one, paying attention to the arrows on the sides of the filter.
Finally, close the access panels and turn the HVAC unit back on. It's recommended to change the air filter every month, especially during higher winter and summer months when the air conditioning system operates at its maximum capacity. If you have an HVAC unit that tends to be used almost all year round, it's best to replace the filter every three months. Each HVAC filter has a MERV rating which measures its efficiency in capturing contaminants that pass through the heating and cooling system.
To find the right size filter for your system, check your manual or measure it yourself. Once you have a new filter, locate where your oven filter is; some filters are located on the ceiling, but most are in the ducts near the oven. Then, replace your air filter regularly to improve indoor air quality and help your HVAC system work more efficiently. Finally, it's a good idea to perform professional maintenance on your air conditioning systems even if you're trying to replace your air filters regularly.
This will help protect your HVAC system from loose debris or a loose filter that escapes into the duct.
