Hvac what is a plenum

The return plenum box receives used air from the return vents and distributes it to your HVAC unit to be heated or cooled again. The cost of a plenum box repair depends on a few different factors: whether it is the return or supply plenum, what state the unit is in, and whether your technician discovers any other issues. Plenums are deceptively simple, but incorrect installation can cause big problems for your HVAC equipment.

If a plenum is installed in a way that does not allow for smooth airflow, you might end up with frozen direct expansion coils, tripped furnace limits, failed heat exchangers, and failed compressors.

You can also lose a great deal of efficiency if air is leaking from your plenum boxes. Having installation or repair done only by a skilled HVAC contractor will ensure that your plenum boxes are set up to do their jobs without fail.

Consumers that live in dusty areas or homes with poorly sealed ductwork may need to clean the filters once a month.

When they become clogged, your system has to work harder and the air quality in your home decreases as well. While changing the filter is simple the area around the filter in the plenum can also become dirty. For dust and loose debris, you can simply use a vacuum cleaner with a hose attachment but will need to find a suitable cleaner for grime on the plenum itself. Aside from keeping your plenum clean and the filter replaced, most maintenance is handled by professionals when something is amiss with these air distribution boxes.

With that in mind, be mindful of placement in areas with exposed ductwork. Plenums can be damaged or moved if bumped hard enough which can weaken or break the seal with your ductwork. If you intend to use a professional HVAC technician, which we recommend, then you simply need to familiarize yourself with the materials and options commonly used today. The cheapest alternative are plenum duct board kits , which are simple to install, but not exactly durable.

Some of the best plenums are in this class with an R6 insulation rating. There is a supply duct that is about 3 to 4 inches wide but no return. How can I get the system balanced so that all rooms have the same temperature all over the house? Oh, the outside wall of the converted garage is insulated. Mike, I just noticed that behind my return air filter is a large space about 3 feet deep and 2 feet deep.

This space has trash and dust from when the house was built in early I always thought this space should be much smaller and cleaner since it negates the need for a filter air is being sucked into a dirty space.

Your thoughts Please? Additional info, this is a sq feet home and the outside wall of the garage is insulated.
