Modern HVAC technology

I know, I know. It’s never a good idea to rub it in someone’s face when you happened to know something they didn’t. I just have a hard time keeping my comments to myself when the answer has seemed so entirely clear to me all along, and no one will stop to listen to what I have to say. That’s how I get myself into big trouble time and time again with my significant other. He is constantly disregarding my good advice, getting himself into hot water, and then acting as though he’s baffled when the solution was what I told him in the first place. This time, though, he really took things to a new level with his stubborn attitude when he refused to have our central heating system examined by a professional HVAC technician. For a year, our furnace has not operated correctly. It has produced patchy warmth, with many days that our home doesn’t ever reach the target temperature set on the thermostat. There is regularly cool air flowing from our air vents even though the furnace is chugging along at full steam, leaving me to assume that there is some sort of problem with the heating device. I’ve been asking my significant other for many months to please help me to afford a professional HVAC service, so we can finally have our furnace running properly before winter sets in. He refused and procrastinated so many times that we had no choice but to fire up the heating system last week for the first time… only for the entire furnace to implode upon startup. Now the only thing that’s keeping us warm are the heated arguments we’ve been in as we attempt to select a whole new central heating system.
