HVAC not working great

Sometimes I feel like I hate myself. I typically seem to make the most foolish decisions. I experienced an HVAC system failure plus that’s because I kept putting off the necessary HVAC maintenance! It was just the other month too when my engine in my SUV locked up because I failed to change the oil on time! I went way over the suggested oil change mileage! So I basically destroyed my SUV and my HVAC unit in the course of a few months. I think at this rate I’m going to burn the lake house down on accident somehow, someway! I’m trying to get it together here and learn to take care of all my important maintenance needs. I purchased another car, but a cheap one! Honestly, the thermostat wasn’t even entirely working good in the car! I mean the heating was working a little bit, however the air conditioner failed to work altogether. I knew that I had to take care of my HVAC unit before anything and when the HVAC specialist looked it over, he was surprised. He said the HVAC duct was clogged up and the air filter was the worst he has ever seen. I couldn’t believe that I let it go that long without changing it. He said that I was lucky that the heat exchanger wasn’t cracked or I would have to purchase a new HVAC unit altogether. Thankfully, he was able to clean everything out, put in a new air filter and get the unit working after a few minutes. I was so thankful for my working HVAC although I was disappointed with the expensive repair bill!
