There are many things to take into consideration when deciding which option will better serve you. It’s not always an easy decision to make. It’s important to take your time and consider the pros and cons for your exact situation.
The first thing you’ll want to look at is the age of your air conditioning unit. If it’s more than ten years old, it’s probably time to really consider getting a new unit. They simply do not function as well as newer models. There is a good chance that the SEER rating is below the current standard, which means your unit does not have the energy efficiency that it should. A more efficient unit will certainly save you money on your monthly electric bill.
