Clinks, pops, squeaks, or grinding. If you are hearing sounds that the unit never made before then it is time to call a professional. Even if the system still provides you with adequate temperature control, the sounds are an indication of am issue that lif left untreated will likely develop into a more expensive repair.
Look around the system. Is there lots of condensation or perhaps pools of water? This could be either a problem with the refrigerant which has started to leak or a problem with the drainage system. If you find these issues in your HVAC system, then maintenance or repairs should be the next step.
If you find that there is a pungent odor from your HVAC system, then there are usually two possibilities. 1) there is a problem with the wiring and some of the insulation has burnt away. 2) If the small is musty, then it means that there is pooled water in the system that has become a breeding ground for mold and mildew.
Are different rooms different temperatures even though they are controlled by the same thermostat? This could be an issue with the thermostat itself for possibly the duct work.
