What affects the price

Then there is the efficiency rating of the unit itself; higher-rated systems cost more upfront but often lower monthly utility bills. You also have to consider the brand, the type of fuel source, and whether you need to upgrade electrical components to handle the new equipment. Exact pricing confirmed free on the call.
