How Long Do Air Conditioners Last and When Should You Replace Yours?

According to, a central air conditioning unit usually lasts for about 15 to 20 years. So, if your unit is approaching that age, you may want to consider replacing it. Moreover, you may save 20% to 40% by replacing it with a newer, more efficient model.

Generally, there are several factors that determine the air conditioner’s lifespan. The first factor is how often you use the system. Turning off and on constantly during hot weather puts wear and tear on the system. Additionally, any build-up of dust and grime will damage the AC compressor. This is the part of your AC system that pumps the freon throughout the system.

Second, if the house is too large for the unit. The wrong size unit will quit sooner than one that is the correct size for the square footage of the house. Finally, while freon lasts forever, your unit can develop leaks, especially in the evaporator coil. After all, this is one of the main parts of the unit that can corrode and cause leaks. These leaks will allow the freon to escape, causing the unit to stop cooling.

Can You Afford a New Central Air Conditioner?

Prices of new air conditioning units depend on some variables like the size of the unit, brand and efficiency rating. Then you must add in the cost of installation and any additional work to prepare the space. Typically, prices range from $3700 – $7000 with the average at about $5400.

When looking for a new unit, you’ll want an energy-efficient model to lower your energy bills. There are 2 types of ratings used to rate air conditioner units, SEER (Seasonal Energy Efficiency Ratio) and EER (Energy Efficiency Ratio). Mainly, manufacturers use the SEER rating with the more efficient models rated at about SEER-23. SEER measures the efficiency of the unit over an entire season. The higher the SEER rating, the lower the utility bill, but the higher up-front cost for the unit.

Likewise, EER also measures a unit’s efficiency and again the higher the number, the more efficient. Although, EER is a measure of how efficiently a cooling system will operate when the outdoor temperature reaches a certain level

According to some specific things you should look for when buying a new central air conditioner are:

  • Thermal expansion valve and a high-temperature rating (EER) greater than 11.6, for high-efficiency operation when the weather is at its hottest
  • Variable speed air handler for new ventilation systems
  • Unit that operates quietly
  • Fan-only switch, so you can use the unit for nighttime ventilation to substantially reduce air-conditioning costs
  • Filter check light to remind you to check the filter after a pre-set number of operating hours
  • An automatic-delay fan switch to turn off the fan a few minutes after the compressor turns off
