According to Energy Star Canada, a central air conditioner can run for 15 years or more. However, some units show their age as early as 5 or 10 years. Check your unit for the common ageing symptoms below.

Refrigerant Leaks
Refrigerant is a liquid substance that creates cool air by absorbing heat. The heat turns the liquid into gas, then restarts the cycle again — at least, when the AC unit is working. But when an AC unit has a problem, refrigerant may leak instead. While leaks in newer units are preventable with regular maintenance, leaks in older units are often a sign of age.

Maple Air Heating and Cooling, serving the Greater Toronto Area, can check your refrigerant levels and advise you on whether you can repair or should replace the unit. Never attempt to check your unit's refrigerant levels or repair refrigerant problems yourself as it can endanger your health.

Worn Out or Dead Compressor
Refrigerants turn back into a liquid partially because of the compressor. Without the compressor, refrigerants cannot change properties as needed. By extension, they also cannot cool your home. Unfortunately, a common problem in older AC units is a worn or dead compressor. Like refrigerant leaks, worn or dead compressors can highlight the unit’s age even with regular maintenance. Consult our Maple Air Heating and Cooling experts, serving the Greater Toronto Area, to determine whether it's more cost-effective to repair the compressor or replace the unit.

Worn Out Air Conditioner Fans
Fans are another important part of the cooling cycle. Their function can vary from unit to unit. However, in most conventional units, one fan blows air into the room and another vents hot air back outside. Like compressors, these fans are subject to wear and tear and must be regularly maintained by a professional.
