The Most Common AC Breakdowns and How to Repair Them

What is more annoying than an AC malfunction in the middle of the summer? In a retail store, it can cause customer dissatisfaction. In an office, it can lead to significant productivity loss.

In a server room, it can cause irreparable damage to costly hardware. And in any case, an AC breakdown will cost your company time and money.

This article will cover the most common causes of AC failures, explain why they occur, and discuss possible fixes through HVAC Maintenance.

Refrigerant Leaks

Symptoms and Causes: Suboptimal cooling performance or evidence of icing on your AC unit strongly indicates a refrigerant leak. This problem often arises from refrigerant lines’ wear and tear or manufacturer defects. Improperly installed or serviced units can also lead to leaks.

Implications: Refrigerant leaks decrease your AC’s cooling capacity, causing the system to work harder and consume more energy. Prolonged leaks can also lead to compressor damage, one of the most expensive AC components to replace.

Solution: You will require professional intervention to resolve refrigerant leaks. HVAC technicians can identify the leak source, seal it effectively, and recharge the refrigerant to the necessary level. Early detection and repair can prevent further damage and improve the system’s lifespan.

Clogged HVAC Air Filters

Symptoms and Causes: Blocked air filters are the prime suspect if your AC airflow has decreased or indoor air quality has deteriorated. As the filters continuously trap dust, allergens, and other airborne particles, they can get clogged, impeding airflow through your AC system.

Implications: Clogged filters compromise the AC system’s efficiency and air quality, leading to health issues for building occupants. They also force the system to work harder, increasing energy consumption and causing premature system wear.

Solution: Regular HVAC filter replacement or cleaning can restore airflow and indoor air quality. It’s a straightforward task that most people can handle without professional help. Inspect the filters monthly and replace them every 1-3 months, depending on their condition and the manufacturer’s recommendations.

Electrical Issues

Symptoms and Causes: If your AC system frequently turns on and off without reason, electrical problems may be the cause. Loose connections, corroded wires, overloading, or breaker malfunctions are common sources of these issues.

Implications: Electrical problems can lead to a total system shutdown if ignored, potentially resulting in a costly replacement. They also pose a safety risk, as electrical faults can cause fires.

Solution: Trying to fix electrical issues on your own is a terrible idea as it poses numerous safety risks. Ask for professional technicians’ help. They can examine the system, identify the problem, and safely rectify it to restore normal operation.

Thermostat Malfunctions

Symptoms and Causes: Inconsistent indoor temperatures often signal thermostat issues. Incorrect calibration, depleted batteries, or outdated models can lead to such inconsistencies.

Implications: A malfunctioning thermostat makes temperatures fluctuate, which creates discomfort for tenants. Such breakdown can also lead to increased energy waste due to inefficient system operation.

Solution: Recalibrating the thermostat, replacing batteries, or upgrading to a modern, programmable model can restore temperature consistency. Dealing with advanced thermostats that require careful installation and calibration may need an HVAC professional’s help.

HVAC Drainage Problems

Symptoms and Causes: Whenever you see water pooling near the AC unit or signs of water damage, blame it on drainage issues. Blockages in the drain line can be caused by dust, dirt, or algae. They prevent the proper drainage of condensation from the AC.

Implications: Untreated drainage issues can lead to mold growth, structural damage, and unhealthy indoor air quality.

Solution: In most cases, you can clean your AC drain line by yourself if the system is not particularly complex and you’re comfortable doing it. Do it regularly to prevent water backup. However, if drainage problems persist, professional intervention may be necessary to prevent more serious damage.

Mechanical Wear and Tear

Symptoms and Causes: Unusual noises or a decline in cooling capacity may indicate mechanical wear and tear. Continuous operation, along with dust and debris accumulation, contributes to gradual wear on system components.

Implications: Mechanical wear and tear can significantly reduce the AC system’s efficiency, potentially leading to sudden breakdowns or expensive repairs.

Solution: Regular preventive maintenance checks by professionals can identify worn-out parts before they cause major problems, ensuring uninterrupted system operation.

HVAC Maintenance Makes the Difference

Understanding common AC issues can help fix problems faster. But here’s the key – regular HVAC maintenance can prevent most of these failures.

This simple practice can make your system work better and last longer, while also avoiding serious breakdowns. So, staying on top of your routine checks can make a big difference for your air conditioning equipment and your business.
