Proper care of a downflow gas furnace starts with proper installation and continues through routine cleaning and maintenance. But before you can even have a downflow gas furnace installed, you need to make sure it’s the right fit for your home.
Downflow gas furnaces are so named because of the direction that air flows through them. The cooler air is taken in at the top and directed downward, heating up as it travels, and then is expelled through the bottom of the furnace into ducts that feed the rest of the house. Because of this configuration, downflow gas furnaces are typically installed in attics as opposed to basements.
If you have a basement and you’d rather install your furnace there, then an upflow furnace is probably the better choice for you. However, as many newer homes don’t have basements at all, downflow gas furnaces are growing in popularity and usefulness.
As with any other furnace, it’s important to have a downflow gas furnace professionally installed. This will ensure that the venting system is properly in place and that your house will be heated as effectively and efficiently as possible.
Of course, there are some other things you can do to help your furnace heat your home and keep your energy bills down. For instance, make sure you have proper insulation everywhere, particularly in the attic and crawlspaces where much of the normal heat loss in a home occurs.
You can also make your home more airtight in the winter by sealing up any unused windows and doors with plastic and making sure all storm windows are in place. Basically anyplace that a draft could develop, you could be losing heat and that costs you money. So to ensure that all of the money you’re spending to heat your house is actually going to that purpose, check periodically to make sure your home is still sealed up tight.
Also, just like any other type of furnace, a downflow gas furnace will require regular maintenance to make sure it continues to run efficiently and to replace any parts that may have worn out over time. Having a professional technician come out once a year to carry out this type of service will wind up saving you a bunch of money and can help catch problems before they are able to get out of hand.
