Several issues can cause an air conditioning (AC) system breakdown requiring Murrieta AC repair. Understanding the primary culprits behind AC failure helps prevent unnecessary breakdowns and expensive repairs.

Poor Maintenance

Lack of routine AC maintenance like filter changes, refrigerant checks and coil cleanings is a major cause of AC system failure requiring Murrieta AC repair. Dirty filters restrict airflow and reduce efficiency, while low refrigerant leads to compressor damage. 

Worn Parts and Components

Old, worn and failing parts are another leading cause of AC breakdowns requiring Murrieta AC repair. Components like contactors, relays, capacitors and compressors deteriorate over time. Regularly inspect parts for signs of wear and replace them before failure occurs. Consider replacing parts every 5-10 years for proactivity.

Refrigerant Leaks

A common cause of AC breakdowns requiring AC repair in Murrieta is refrigerant leaks that allow the coolant to escape over time. Even small leaks that go undetected can eventually cause compressor failure. Signs of leaks include higher electric bills and a decrease in cooling power.

To prevent unnecessary AC breakdowns:

• Change filters every 3 months and clean coils yearly
• Inspect parts and components for wear every 1-2 years, replacing them as needed
• Rodent- and insect-proof the AC system and protect vulnerable areas
• Have a reputable HVAC company check for refrigerant levels and leaks annually

Following these proactive steps helps keep your AC system running smoothly, reducing the need for expensive AC repair in Murrieta caused by neglected maintenance.
