My mother consistently told me, if you do it once it is your work. When my boyfriend Steve and I moved in together, I took that advice to heart. I am super careful about whatever job I do. I do the meal prep, laundry and all of the cleaning; Steve has to repair anything that breaks, handle garbage and deal with our funky HVAC system. Steve is totally going against the rule though. He keeps trying to change out his HVAC work, every now and then he will do laundry. Sometimes he will make lunch. Then he will later on mention the HVAC is not turning on again. I am not touching our HVAC unit. If I even mess with it once, I know I will forever be the HVAC repairman. I realize that heating and cooling systems come with a lot of work. That is why I never stepped near it. Every month you need to take out and clean the air filter, and you also have to replace the Freon within the AC a lot. The furnace blower needs to be oiled a lot, and also there are quarterly HVAC tune ups that need to be scheduled. Even doing this, there will be frequent HVAC repairs time and time again. I love that it is Steve’s job to worry about that. He keeps trying to get me to do them. He does not realize that I will go with no climate control before I mess with the HVAC system. It is worth it to never have to worry about it.
