I'm just thinking he is trying to correct something that's not a problem. Lots of ale yeast do well at the 58 - 62 temp range.
Air temp and ground temp are 2 very different things. Boston (like most of the NE) is having an unusual heat wave right now that will end tomorrow (here in PA we've been in the 90's for the last 4 days and tomorrow the high is 65F and the low near 50). Look at their 10 day forecast and you will see the majority of the days are in the mid-low 60's and at night in the upper 40's. That is AIR-temp. The ground temp at basement level will be much colder and will stay that way for the majority of the summer.
Remember even when soil temp at hop/vegetable/flower levels gets warm the soil several feet down will maintain a much colder temp, and that is where the basement will be losing the heat.
