Rebates Can Make the Difference
When shopping for a system, remember to consider potential rebates that the system you are considering could be eligible for. After factoring in rebates and a lower operating cost (thanks to higher SEER), a more efficient system with a higher upfront investment could end up being cheaper in the long run!
