Can I, the home owner, safely replace the filter?

Here is a link to the Lennox G43 Owners Guide. On page 4 it advises you to check your filter(s) monthly. It also provides details on what filter is needed. Most homeowners are able to check the filters on their own. However if you feel uncomfortable doing it yourself, you can always hire a licensed contractor to do routine maintenance. You may want to consult with the contractor during the visit on doing it yourself in the future.
