Heating and cooling systems that are well maintained can last anywhere from 15 to 25 years. If your AC unit is over 10 years old and you have seen an increase in your energy bills, you may want to look into upgrading to a new unit with higher efficiency ratings.
Choosing the AC unit with a lower price does not always equal the best value. The minimum standard SEASONAL ENERGY EFFICIENCY RATIO, or SEER, rating for heating and cooling systems has increased in the southern region. The rating, which measures the energy efficiency of an air conditioning system over the course of an entire cooling season, has increased from 13 to 14 in many areas throughout the U.S., including Georgia. A higher efficiency system might cost an extra $800 up front, but could save you $300 per year in energy costs.
Regular maintenance is necessary to keep your HVAC functioning at optimum levels. Over time, dirt, debris and other foreign substances can cause build up in your system, erode electrical connections and cause other damage that is expensive to replace. Ensuring your system is clean and maintained annually can extend the life of your system and help you avoid expensive and preventable repairs in the future.
