What is the average life expectancy of an air conditioning system?
Most systems have a lifetime of 10 to 20 years. As your equipment gets older, its efficiency can decrease dramatically. You may notice that it gets noisier and needs repairs more often. When a unit begins to show its age, you have two choices: overhaul the system or replace it.
Because heating and air conditioning technology improves over time, a unit designed with newer, more energy-efficient equipment makes sense, especially if your system is 10 or more years old. Our authorized air conditioning and heating professionals can provide an in-home estimate on the cost of a new system.
Will installing a bigger air conditioner perform better?
No, you don’t want your heating or cooling system to be too large. Air conditioners control the comfort level in your home by cooling the air and by removing humidity. An oversized air conditioner can cool your home faster, but it will use more energy and will not remove humidity adequately. In addition, your existing ductwork may not be able to support the airflow of a larger system.
A unit that is too big for your home will have short-run cycles. It can take only a short time to cool the air, but the unit shuts off before enough air blows across the indoor coil where moisture condenses into water and drains from your system. Too much moisture left in the air can lead to mold and mildew problems. These short-run cycles also mean your system starts and stops more often, which uses more energy and causes a lot of wear and tear. An air conditioner operates more efficiently during long-run cycles.
