Constant Hissing Noise from Turned Off Condo HVAC

History
I moved into a new condo build in June 2015 (not even registered). Initially the building HVAC system was not turned on, it was still under going the final phase of set up. Builder still had to have the plumbers come in and ensure the valves where in the correct positions.

After the plumbers came, a constant faint hissing noise could be heard from the HVAC in my bedroom. Please note the building HVAC system was still not turned on. Complained to the builder about the noise and they had come and check the system. Afterwards, no noise.

Building HVAC system was turned on, I did not need the AC as the weather had been cool and did not turn on the HVAC.

A few weeks later a fishy mold smell was being emitted from the HVAC unit. Complained to the builder, they had the plumber come and check out the system. Afterwards, the smell decreased (still there, especially in the mornings), but the constant hissing noise returned (louder than before).

Complained about the noise and they had a plumber and a representative of the HVAC unit inspect the unit, and was told that "This is normal. That it will dissipate as more people move in and use their HVAC".

I can live with the smell....alot of air freshener, but the noise is making sleep impossible.

What I do not understand is why they where able to fix the noise the first time, but now they are saying the noise is normal.

Should I be contacting HVAC person to check on the unit?
