The key to an effective and efficient HVAC system is making sure your ducts and vents are always open and clean. Over the years, your HVAC system is bound to get a little clogged up and dirty. Usually, this dirt doesn't do enough to reduce the airflow of your system, but it can resulted in dirty air that causes allergies. However, your HVAC system can get clogged at certain junctions, leading to a malfunctioning furnace and/or air condtioner. This article explains 2 ways to service your system so it runs more efficiently.
How to Clean the Output Pipe Vent
One of the quickest and easiest ways to service your furnace and AC unit is to clean the output pipe and vent. The furnace has a pipe that moves air outside of your home. This helps the blower in circulating air into the ducts and into your home (whether you are running the AC or the furnace). The output pipe runs out of the bottom of the furnace and into the walls, where it eventually comes out on a nearby exterior wall. Finding the output pipe is usually simple. It is often just 3" or 4" off the ground and it has a small vent covering it. This vent is made to prevent outside dirt from getting in to the pipe in clogging. However, the vent can get clogged from both inside and outside. It is very useful to frequently remove the vent from the pipe and clean it on the inside and outside. Cleaning the vent on your output pipe will only take a few seconds, but it could drastically improve the air flow of your furnace.
How to Clean the Filter
Every furnace also has an air filter. This filters out dirt and dust that the furnace blows out, before it gets to the ducts. Furnace filters can last a very long time before they need to be replaced. However, they can get especially dirty and dusty if they are in a room that is also dusty. The filter is attached to the actual furnace unit and you can find it very easily. It has its own compartment which you can access by simply opening a door (no tools required). If you cannot remember the last time you replaced your filter, now is the perfect time to do it. Furnace filters are affordable and easy to replace.
As you can see, these two basic jobs will only take a few minutes of your time. But in the long run they could help your HVAC system run more efficiently, saving you some cash in the process. If these don't improve your system much, or if you have larger issues, contact a company that specializes in heating and air conditioning repairs.
