The compressor is often referred to as the heart of an air conditioning system because it circulates refrigerant between the indoor and outdoor units. When the compressor fails, your AC unit can no longer cool your home effectively, resulting in the need for AC repair or a full system replacement. Understanding the common causes of compressor failure can help you avoid unexpected breakdowns.
Here are some of the most common causes of compressor failure that we see:
- Lack of routine maintenance—Dirty air filters, clogged condenser coils, and restricted airflow force your compressor to work harder than it needs to, which can lead to excessive wear over time. Low refrigerant levels can also put strain on your compressor, causing it to overheat while struggling to maintain the desired temperature.
- Electrical problems—Damaged wiring, faulty capacitors, or power surges can keep your compressor from starting properly or cause internal damage. In some cases, overheating because of prolonged operation during hot weather can shorten the lifespan of your compressor. This is especially true if the outdoor unit is blocked by vegetation or debris.
- Unit age—Most air conditioners last between 10 to 15 years and as your system ages, your compressor will naturally experience wear. If your AC unit is nearing the end of its lifespan and the compressor fails, replacing the system can be more cost-effective than another AC repair.
We highly recommend professional maintenance to protect your AC unit’s compressor. For more information or to schedule an AC repair, contact us today.
