When my wife and I we had to replace our forced air furnace and central air system in the late autumn due to carbon monoxide literally the evening before our son was to be born, I felt under pressure to get something in place.
I told them I needed a more powerful air conditioner for all the unique heat-generating equipment in my basement, especially since our old system had trouble keeping up. They said that the new unit was more than enough for the square footage. I reiterated again, that air conditioners don’t cool square footage, they cool BTU’s, and the average home doesn’t have a grow op and server farm in the basement generating heat. Then, they decided to hit me with the old “I’ve been doing this for {x} decades” speech.
Needless to say, I’ve had to consolidate servers, stop indoor gardening, replace the bulbs in the house with those shitty blue-hued LED’s that can’t dim right (and dimmer switches to handle the change in load characteristics), take the weather into account when cooking indoors and clean both sets of A/C coils on a more frequent basis. The air conditioner still can’t keep up and when we have a string of hot days, we can’t always count on the cooler evenings to get the house back down to “room temperature”.
Oh, and now our old chimney drips water into the basement.
