While expensive, that's an impressive turnaround on the time frame. But being in Florida, I imagine A/C systems can be a high priority. Even still, a 2 day turn around for that sort of job is impressive. Not many contractors I've interacted with either privately or through work in facilities management can get that sort of turn around and live up to it.
I live up northeast of Edmonton, Alberta, where it's all about the heating - it's code to have more than 1 heating source in case of a power or gas outage during the 5 or 6 months we're living in an arctic wasteland. 10 degrees below freezing is a warm day this time of year here, so I have to laugh when Floridians post pictures of the frost they get.
