    Question Variable Speed vs Multi Speed: Thermostat Critical?

    I have read here that Variable Speed is superior to Multi-Speed when it comes to blowers, but most of the comments I've read involved having a specific level of thermostat.

    Is a high end thermostat a requirement for getting the most out of a VS blower?

    If we assume a relatively dumb/cheap thermostat on both units does the VS still hold a large margin over MS?

    Also there have been comments about cost-to-replace: Are VS blowers considerably more expensive to replace than MS ones?

    Thermostat doesn't matter for VS/Multispeed unless it's a communicating system. A better thermostat will make either system work better.
