How To Repair 4 Common Furnace Output Hose Problems

Posted on

Without a functioning furnace, your house could get mighty cold this winter. When it comes to central heating, it is best to get your furnace up and running as soon as possible--don't wait until winter is in full force. Before you call an HVAC specialist to come to your home and service your furnace, there are a few checks you should do yourself. This article gives you 4 things to check on your furnace output hose. These tasks will only take up an hour of your time, so you can do them immediately.

Repairing the Hose Between the Furnace and the Duct

Every furnace is slightly different in its construction, but all will have some sort of hose or duct that connects the furnace to the central duct system. This junction is of critical importance when it comes to the overall airflow of your heating system. If the junction has an aluminum hose, there is a better chance of it getting kinked, punctured, loose, or clogged.

Kinks

A kinked hose will be easy to identify. Kinking can happen as the furnace is turned on and off during normal usage. The sudden burst of air through the pipes can cause it to shift and maybe even kink. If this happens, it is best to just completely replace the hose.

Holes and Punctures

To find holes in the hose, you need to run your furnace. As soon as the fan kicks in and you hear the air blowing feel near the hose. Any air flow you feel could be coming from tiny holes in the hose that are too small to see.

Loose Connections

Another common cause of escaping air is due to the hose ends being loose. The hose can easily get knocked loose. Some hoses are secured to the fitting with a hose clamp, while others might just have duct tape. Buy new hose clamps, and/or new duct tape to reinforce the connections. A hose clamp that is reinforced with duct tape will stay air tight for a long time.

Clogging

Clogging in your hose is probably impossible to detect unless you remove the hose from the connection. Look through the hose and make sure there is nothing blocking it. Also check the perimeter around the connections for any blockages.

If these repairs don't improve the air flow of your furnace, you should call an HVAC specialist. As soon as your furnace is professionally serviced, you can start to enjoy an HVAC system that is running at maximum efficiency.
