First floor of home not getting any hot air

Hey all!

We recently purchased a townhome. The townhome was built in 2019 (so only ~3 years old). It is a 3-floor townhome. The 1st floor contains the entrance and one bedroom, as well as the garage. The 2nd floor contains the living room and kitchen. The 3rd floor contains more bedrooms. For some reason, we are not getting any hot air coming out of the vents on the 1st floor of the home. I am confident that the vents/dampers are open. I have checked them multiple times. The furnace is located in the garage on the 1st floor, and the 2nd and 3rd floors each have their own Nest thermostat.

Here is a quick diagram of the home/situation:

Any ideas on what could be causing no heat to come out of the 1st floor vents? Thanks for any help!

Sounds to me like the ducting is dis-connected somewhere. Do you get no air or just not hot air? What controls the temperature to the first floor?

OK, have you tried partially closing the vents on 2nd & 3rd floor to see if more heat is pushed to 1st floor.

This in nothing more than a typ basement being cold (1st floor) because we all know heat rises!

Then you are in trouble.
If the first floor damper is open and you aren't getting any air on the first floor..... there is a problem.
