Budget and Total Cost
I did not focus only on the sticker price. I also considered installation costs, maintenance, and possible energy savings over time. For me, the best option was not necessarily the cheapest one, but the one that offered the best overall value. I wanted a system that would perform well for years without causing unnecessary expenses.
