Heat pump expenses

Hello my name is Jessica and I'm a single mom to two boys. All three of us have medical issues and life has been challenging but we make the best of it. It's been just the 3 of us for the past 3 years and although I try my best to use the resources available the heat pump going out is an expense I just can't cover. I did get approved for a rebate through my electric company but we are still left with $3000 to come up with in order to replace our heat pump. Asking for help is challenging for me but I can't let winter hit without getting this huge house expense fixed. My boys have been troopers with our AC out but with our cold winters I don't want to put them through that. If you can please help us meet this goal it would be a life saver. If you don't have change to spare I completely understand but hope you can share this so that we might just get a chance at getting this covered. I thank anyone who's taken the time to read this!
