HVAC creating a slight metallic smell every time it starts up (lemmy.ml)

The best way I can describe it is when you have an oven on clean mode, that you start smelling that metallic kind of smell.

The watchmen came and put new filters on the HVAC unit, but I still get a wiff of it for the first 20-30 seconds of the unit starting up, and then it doesn't smell anymore. I'm wondering if whatever that smell is, is unhealthy, and what it could be?

Would getting a higher MERV filter help or is it likely something wrong with the unit?

Does it happen during heating or cooling?
