HVAC

My Heating Ventilation Air Condition (HVAC) went out in May 2020. My brother brought me a window unit which helped during the summer but now it is turning cold. I have raised 2200.00 but I still need to raise 2600.00. I have bipolar mental illness so I am struggling to stay in my home. Working in my yard in the Spring, Summer, Fall and well Winter also keeps me going clears my head to combat my mental illness. Please help me raise this 2600.00 to help me buy a new HVAC unit.
