I don't think what you are looking for really exists, in terms of a standardized list of HVAC/services loadings. Building codes don't usually specify dead loads, probably because they are, in principal, known. Typically only imposed (live) loads are specified. From the buildings I have worked on the services loadings were essentially copied from similar buildings/agreed with the HVAC contractor. There are some generic guidelines available. For example:
The Structural Engineers Pocketbook uses 0.15 kPa for ceiling and services
The Arup Structural Scheme Design Guide has 0.25 kPa nominal and 0.4 kPa for HVAC (I only have an old version so don't know if that has changed...)
The Steel Construction.info site (which is a pretty good resource) has 0.25 kPa as being a typical services loading.
ASCE 7-10 in Table C3-1 lists a dead load of 4 psf as a minimum 'mechanical duct allowance'. Which is likely where the 4 psf (0.19 kPa) mentioned in the comments originally came from and is consistent with the above references.
The Designing Buildings Wiki has 0.85 kPa for Raised floors, ceiling and building services equipment combined.
Hard to say if these would be applicable to your situation. Also
you would need to deal with heavy equipment (condensers, fans, heaters, etc) which are not considered in these loadings.
The HVAC contractors tend to want to put holes all over your structure as well, so it would probably save time and money to consult with them early in the design and sort out what they need.
