A multistage system produces heat at two or more rates. This design allows room temperatures to be kept consistent.
According to HGTV, multistage systems require less electricity to keep temperatures constant than traditional heating and cooling systems, making them a more efficient choice.
The cost of installation for multistage heating and cooling systems varies depending on the brand and exact model of the system. Although initially prices could be expensive, the amount of money saved on utility bills in the long run makes them a better option than standard heating systems.
