My grandson likes to play around with my heat pump. He’ll take pine needles and drop them into the unit while the fan is on and watch them get tangled up with the fan. I don’t really mind as long as he doesn’t get hurt. The heat pump has protective bars around it to prevent someone from getting their fingers caught up in the fan. Still, I don’t really feel comfortable with him playing with an HVAC device that has moving parts and is connected to a high voltage electrical source. I guess I’ll just have to make the heat pump off limits, but I don’t like to be the kind of grandpa that is always setting limits. When I was a kid we didn’t have HVAC systems with heat pumps and the like. We simply had window air conditioners and a gas furnace. I guess there were less things for us to get into trouble with back then. When you think about it, what little boy wouldn’t be attracted to a machine that blows air and makes a lot of noise? He also likes to fiddle with the thermostat. Even though the thermostat is high on the wall, it is lighted up so he is attracted to it in the dark hallway where it is located. He is always wanting me to lift him up so he can play with the buttons on the thermostat. Sometimes I let him change the temperature so he can learn his numbers better. He also likes the way the thermostat beeps when you adjust it. Maybe he’ll grow up to be an HVAC provider!
