Where are these noises coming from?

I recently upgraded my Heating & A/C equipment. I used to have central Heating & A/C that used air duct throughout the house. The air duct worked to get every room to the same temperature. My family and I hated this. I have 3 sons, a picky hubby and I am not exactly easy to get along with. The group of us could never agree on a heating or cooling setting. Both of us all had a unusual temperature preference. It seemed like all year long every one of us would change the thermostat over and over again. My hubby would always lower it, my oldest child would raise the temperature, my middle child would adjust the fan speed and my youngest child would turn the Heating & A/C off. Because the rapid fire Heating & A/C changes were costing myself and others currency, I changed the type of Heating & A/C every one of us had. My family and I now have ductless Heating & A/C. The ductless mini chop has an air handler and thermostat in each room of the house. Every room can have its own certain  temperature control program. This is called Heating & A/C zone control and it is amazing. My household has never been so glad. Each of the women control their own Heating & A/C needs in their dining rooms. Our community areas like the residing room and home office, are only slightly off from 1 another. Everyone gets along way better now and the zone control has entirely saved myself and others currency. I have certain rooms of the beach house that hardly get any Heating & A/C. My youngest child rarely even turns her on too. Also, the thermostat settings are never messed with anymore.
