How can we sound proof basement?

Out HVAC is in basement.  We can hear furnace running in the basement when we are sitting in our living room and it is very loud. How can we sound proof it?  Shoud we cover  the top of the furnace?


How many inches clearance should we have from the top of the furnace?

    Step 1: Have someone check the furnace to ensure it doesn't require maintenance that would reduce the sound.

    Step 2: Put something to dampen the sound in the flooring.

    Step 0: Don't even THINK about putting sound dampening material anywhere near the furnace.

    as far as how close can you put something to the caseing of the furnace depends on type of heat fossil fuel, electric resistant an local codes. Also the owners manual usually has a schematic showing this.

    But you'd be better off soundproofing the floor you'll get 2 benefits from it lower noise an added insulation for floor which will require the heat to run less.

    But no matter what you do you will still hear some noise as most of your noise is probably coming threw the ductwork.

    NO.  you want nothing touching the top of the furnace.  It's a safety issue.  sound deadening?  insulation on the basement ceiling is the way to go, possibly several inches thick.  this may require building a false ceiling to hold up the insulation.  -- grampa

    Call an HVAC technician.  Blower motor could be bad.

    You know better than to cover the furnace …

    Depending on where it is in the basement… you could enclose it as a utility room.If it’s fossil fuel combustion you need to make sure it has fresh air intake.
