Furnace (gas)

The Home Wizard app calculates your ideal home care program to avoid problems with your Furnace (gas), but sometimes trouble can still occur. Here are answers to questions about furnace (gas) changing air filter.


I am spending my first winter in my home - brick, built in 1938, when I moved in in early spring, a friend installed a programable thermostat for the heating system (furnace, steam radiator). Today, "filter" popped up on the screen - does this refer to changing a filter in the furnace? How is this done? (or what type of professional should I get to do it?)


Dear Nicole:

Yes, many of the good newer programmable thermostats will display a reminder when its time to change the air filter on your furnace.

Regarding your second question, here is a link to a short video that describes how to change a furnace air filter:

As you will see in the video, changing a furnace filter is fairly easy to do, and since you should change them frequently (once a month for some types of filters), this is something that is good to learn how to do yourself.

Hope this is helpful.
