Mini Split Heat Pump

It is designed for 24,000 btu. I did not know whether or not it would become too cold in Tennessee for her to keep my house warm. I bought one. In the description when I looked, he said nothing the system does not work below a certain temperature. When received and read the box, it says it will no longer heat when the temperature drops below 35 degrees F. I think I may have answered my question, but do you think it will work in Middle Tennessee.

Conventional heat pumps have auxiliary electric heater for temperatures below about 35 DEGS. You should check with a local provider to determine if the one you have in mind has this feature. I think so because the external heat pump coils can freeze at temperatures above 35 degrees and there is a need to address this problem. The auxiliary heat is the usual way.

yes, it would be sufficient.
