What to Consider When Replacing Your AC Unit

Discusses the reasons why an AC unit may need to be replaced and what to consider when purchasing a new air conditioner. The five main reasons why AC units may fail are old age, frozen coils, overworked capacitors and contactors, electrical issues, and a defective thermostat. The article suggests that if your AC unit is over 10 years old and needs a major repair, it may be worth considering replacing it with a new high-efficiency unit. Some important factors to consider when purchasing a new unit include energy efficiency, space changes, and cost. Air conditioner efficiency is assessed by its seasonal energy efficiency ratio (SEER), which is calculated by dividing the system’s cooling output over one year by the energy it uses to achieve that output. The article suggests that it is recommended to choose the highest SEER that you can afford, especially if you live in a sweltering climate.
