This is a ventilation system question. The return air path is the route (usually through ducting but could be through some other route such as a window or vent) that the air takes. Typically a building ventilation system would have both supply and extract systems. The return air path is this.

None. Probably the home was built for forced air and converted to boiler/baseboard heating.
SA stands for supply air. Air is delivered to your space from a sort of air handling unit(fan). This is the conditioned air whether heat or cooling. This air would be returned to the air handling unit to be reconditoned through the return air(RA) duct .
If it is the airflow that is making the noise, this is caused by undersized ducts. If you recently had your equipment replaced be sure the airflow is set properly for the size equipment you have. If it is, look into increasing the return air grille size. That may give you some improvement. If the noise is still objectionable the duct size will probably need to be increased.
To replace stair risers effectively and efficiently, follow these steps: Measure the dimensions of the existing risers. Remove the old risers carefully using a pry bar and hammer. Cut new risers to the correct size using a saw. Attach the new risers to the stairs using construction adhesive and nails or screws. Sand and paint or stain the new risers for a finished look.

To replace stair treads and risers effectively, follow these steps: Measure the dimensions of the existing treads and risers. Remove the old treads and risers carefully using a pry bar and hammer. Cut the new treads and risers to fit the measurements. Install the new treads and risers using construction adhesive and nails or screws. Finish by sanding and staining or painting the new treads and risers for a polished look.
Risers on a motorcycle are used to raise the handlebar. The handlebars are attached to the risers which in turn are attached to the front end of the bike. They are cylinders made of metal. dmx
You will hear air circulating in the cold air return (or return air grille) when the heater or air conditioner is running.
Most companies will ship (2) risers in a single set.
A cold air return is similar to a return air grille, which is needed for air to travel to the furnace to be filtered, heated OR cooled and then recirculated.
I need to know what the codes are on stairs? Treads@risers an hand rails ?for what degree of slope
Bleachers are for people to watch, for example, sporting events, and risers are for the performers, for example chorus's.
When replacing stair treads and risers in a staircase, it is important to follow these best practices: Measure and cut the new treads and risers accurately to ensure a proper fit. Remove the old treads and risers carefully to avoid damaging the staircase structure. Use a strong adhesive or screws to secure the new treads and risers in place. Finish the new treads and risers with a protective coating to prevent wear and tear. Regularly inspect and maintain the staircase to ensure safety and longevity.
