I’m not a fan of furnaces.
I feel like they are more work than they are worth. First, you are getting ductwork with a furnace. Ductwork just doesn’t make sense to me. Who wants their entire home the exact same temperature? What about when you cook in the summer or when you go to bed in the wintertime? Zone control is a smarter option. I also don’t like the upkeep there is with ductwork. You need to make sure it is clean since ahir, dirt, dust, and animals can get in there. You also need to ensure there isn’t evena miscrospcoitc hole or the energy bills rise up. Another con to a furnace is that they require a lot of work. I feel like my furnace always requires a good cleaning. I change the furnace filter monthly, vacuum out the inside of it and lubricate the fan motor belt. Even with these monthly tasks I still need to hire out professional heating service. I need a HVAC contractor to take a look at the inner workings and check for rust, dust and corrosion. The heater repairs aren’t cheap either when they crop up. There are certain parts, like the heat exchanger, that are priced the same as the furnace. The furnace also is a fire hazard. If it gets too dirty and then warms up, then it can catch on fire. It also can release carbon monoxide into the air quality. Doesn’t seem like a really safe system at the end of the day.
