What causes a creaking popping noise in hardwood floors.
My hvac floor vent has started squeeking.
And some systems are much louder than others.
One provides the path for the conditioned air to go from the furnace to the rooms around the house the second duct system allows the air in the rooms to return to the furnace for heating or cooling.
The 2 12 floor joists on a 16 foot span are well within span limits for single family residences therefore they are not likely the cause due to excessive deflection.
If so you have a belt drive blower.
For example a house with plenty of return air including return vents in every room.
This is especially the case when at this point in the year it has been sitting for several.
The blower wheel and housing will also squeal when they malfunction.
Outdoor fan motors and indoor blower motors squeal loudly when they re going bad.
All air vents connected to your heating and air conditioning duct system meaning supply registers ceiling diffusers floor vents and return grilles make some noise when the system s fan is running.
Moving on if you feel comfortable remove the cover of your furnace blower compartment.
The average system lasts about 15 to 20 years and there are several things homeowners can do to maximize the life of their system and get the most out of their investment.
Your furnace s duct work can make squeaking noises when it rubs against the floor sheathing.
It s nothing at all.
Creaking popping and snapping sounds can emanate from a hardwood floor that has been nailed to a wood subfloor as well as one that has.
Blower and fan noises such as squeaks squeals and rattles may be transmitted through the duct system.
To start you should know that unless your system is super old or a commercial system it is highly unlikely that your system is belt driven but you never know.
I suspect your squeak is the ductwork sheet metal moving up and down along the shaft of the vertical nail or bracket holding it to the bottom of the floor joists.
If you start hearing a popping noise there may be some issue with your ducts that may need to be repaired such as undersized ducts closed vents flimsy ducts or a clogged air filter.
For some units this sound is normal upon start up.
Hvac systems can be a costly investment one most homeowners should only have to make a few times in their life.
Many units emit a slight squeal under normal operation.
If this is indeed the cause your next step would be to replace the belt or call us.
Do you see a belt attached to the blower.
