Top 6 Causes of Air Conditioner Breakdowns During the Summer

Summer in Denver means warmer days, outdoor adventures, and…the need for a perfectly functioning air conditioner. Just when you need it the most, your AC might decide to take an untimely break, leaving you sweltering in the heat.

We’re here to shed light on the top six causes of air conditioner breakdowns during summertime.

1. Insufficient Preventative Maintenance

Regularly scheduled maintenance is your first defense against unexpected system malfunctions. Some of the crucial elements of preventative maintenance include:

• Checking refrigerant levels
• Cleaning evaporator and condenser coils
• Verifying electrical connections
• Lubricating moving parts to reduce wear

2. Aging AC Units

It’s no secret that as our cooling systems age, they tend to show signs of wear and tear. With most units designed to last between 10 to 15 years, the odds of breakdowns increase as they approach the end of their lifespan.

3. Overworked Systems

During the peak of summer, your AC is under maximum stress. Units that continuously operate during hot periods without any breaks are prone to overheating and subsequent breakdowns.

4. Refrigerant Leaks

Your AC can’t produce cool air without the right amount of refrigerant. Leaks in the refrigerant lines not only impact the system’s efficiency but can also lead to more severe damage if left unchecked.

5. Electrical Problems

The electrical components of your air conditioner perform critical functions. From capacitors initiating the cooling cycle to sensors coordinating the system’s function with the thermostat, any malfunction in these areas can lead to an AC breakdown.

6. Clogged Filters and Blocked Drains

Filters and drain lines can become clogged with continuous use, leading to reduced system efficiency and potential water damage. Timely replacement of filters and keeping drain lines clear can help prevent these issues.

Understanding these common causes of AC breakdowns can help you spot potential issues early and take preventative measures.
