An HVAC unit is a furnace that also incorporates vents and a central air conditioner into your home. Condensation from air conditioning coils contains bacteria that can form slime and clog the condensate pan drain tube. Moisture from outside can also enter a furnace through the duct work, which can cause the rust to grow. Check your central air conditioning unit to make sure it isn't producing condensation that is traveling through the ventilation system into the furnace area. Problems with the condensate pump A series of hoses will be connected to your furnace, whether you have a standalone furnace or one that is connected to an air conditioner as well. After the first stage, the hot exhaust gasses are cycled through a second combustion stage, resulting in exhaust with very little heat. So what exactly is a condensing furnace and what makes it more efficient than a traditional unit? Condensation from air conditioning coils contains bacteria that can form slime and clog the condensate pan drain tube. Complete DIY projects like a pro! If the pipe that runs the condensate to the outside of the house freezes over, your furnace won’t be able to work! If these hoses become blocked up, knotted or obstructed in any way, it could cause the natural flow of water to back up onto the furnace and produce the appearance of condensation. Once a condensing furnace has converted all of its energy into heat indoors, a fan vents moisture and gases outdoors through a PVC pipe. This high efficiency venting system must be installed when you install the new furnace. This can be caused by a few different phenomena but doesn't necessarily indicate a problem with the furnace. Since more heat is pulled from the air as it moves through the furnace, the exhaust air naturally is … His articles have appeared on a variety of websites. Hunker may earn compensation through affiliate links in this story. Lilley holds a Bachelor of Arts in film and video production from the University of Toledo in Ohio. Over the winter months, outdoor heat pump equipment often freezes, resulting in a layer of ice encasing the unit. PVC intake and exhaust vent pipes must be supported all the way from the furnace to the discharge points outside. Typically, there is a combustion issue or bad flue design. Outdoor cooking — Speaking of the outdoors, taking all of your cooking outside will remove the issue of releasing steam into the air entirely. This process creates condensate, or moisture, from the furnace's heat exchanger. Now that you recall what condensation is, let’s answer the next question: Long term condensation leads to various issues with your AC system. If you have a humidifier installed on the outside of your furnace, it may be malfunctioning if you see a puddle of water. This type of furnace contains two heat exchangers that help it produce more heat. If the furnace is producing condensation during the winter, the problem could be that one of these pipes has frozen and is backing up all the way to the main furnace unit. They formed because the warm air got cooled down to its dew point by the cold soda can. condensation in the walls is not a concern in the summertime. Normally condensation does not accumulate on older single pane windows since they are drafty and the moisture passes right to the exterior without a barrier. These pipes run throughout your house, and certain pipes even run outside. I.D. That is why it is rare to see condensation in homes older than 80 years. Stephen Lilley is a freelance writer who hopes to one day make a career writing for film and television. The water vapor and carbon dioxide created go outside. Sagging PVC Vent Pipes. You Think: Natural Gas Furnace -- Water Leaking from the Furnace? In a few seconds, you’ll see droplets of water forming on the outside of the can. Certain types of furnaces naturally produce condensation over time. At the same time, the blower for room air is moving air across the outside of the tubes containing combustion gases. Without this, indoor air will permeate the insulation and condense internally against the pipe. Next, buy a package of slime preventing tablets (one choice is AC-Safe Air Conditioner Pan Tablets; sold at Amazon.com). You can prevent slime and eliminate drain tube clogs in two easy steps. Why your high-efficiency condensing furnace is leaking water First off, consider yourself lucky. Condensation caused by the production of heat must get carried out of your home via pipes. These furnaces often have a specialized drain used to collect the condensation that should prevent you from ever seeing it. Condensation or sweating is a common problem with air conditioner ducts. Other Aspects of High Efficiency Furnace Venting Look in your install manual, most manufacturers will call for the furnace to be installed with a slight forward pitch to allow condensate to drain from the heat exchanger. When you see water puddling around the furnace with the A/C running, you have a clogged condensate drain tube. That usually eliminates clogging for good.
