What is “high efficiency” and why does it matter? As we discussed in the New Systems Installations section, buying a new heat pump can be a daunting decision. One of the most misunderstood aspects is the importance of the efficiency. Most simply put , efficiency to an ac system is the same as miles per gallon to a vehicle. The higher the efficiency is, the less you will spend on your power bill. Many of our high efficiency units come with more benefits than just saving money on your power bill. Some can help with dehumidification and some come with a lifetime compressor warranty. The age of the system your replacing may play a factor in this decision as well. Chances are a base model system is going to be ten to twenty percent more efficient than what’s in place now.
