Help Matthew's Family Replace HVAC System

Hello everyone! My name is Matthew, and I need some help on behalf of my family and house. Unexpected HVAC leaks have caused us to receive quotes that are unattainable for us to pay for at the moment due to rising monthly costs and my current job hunt. I am looking only to cover the replacement of both the outdoor unit and internal air handler as we contend with the back and forth weather changes as Spring approaches (for the past week we have had both snow and almost 80 degree temps).

Currently dealing with fans and electric heaters, we are having to shuttle our children to and from their grandparents as the house shifts from livable to unbearable. Please help if you can, as every bit is greatly appreciated and viewed with the utmost gratitude.
