When the weather starts to warm up, you turn to your air conditioning system for comfort. A well-maintained air conditioner will not only cool down your home but sanitize the indoor air, ensuring you breathe healthy air throughout the cooling season. Nonetheless, air conditioning system failure can occur at any time, leaving you at the mercy of the unforgiving summer heat.

The good news is that you can always count on the experts at an HVAC company to get your home's space-cooling system working properly again. Read along to know some common issues that come up when they are fixing malfunctioning air conditioning systems.

Faulty Compressor

Located inside the outdoor unit of your air conditioning system, the compressor initiates the chain reaction that ultimately cools down your space. 

True to its name, it works by compressing hot refrigerant to increase its pressure and activate its heat transfer characteristics. As a result, it's responsible for maintaining the refrigeration cycle between the evaporator and condenser coils, which carry the system's working fluid — the refrigerant. 

Because your AC compressor works so hard to keep the entire system running smoothly, even the slightest issue within the system can cause it to fail. Some common AC repair issues that may lead to compressor failure include dirty coils, low refrigerant charge, and blocked suction lines.

Clogged Air Filter

As an AC system user, you are expected to regularly clean or replace your air filter. Regular air filter changes are essential to remove airborne contaminants from your indoor space and ensure sufficient flow of cool air within the space.

If you fail to replace your air filter regularly, the performance and efficiency of your cooling system can take a big hit. A dirty filter will reduce the thermal comfort of your home and cause your cooling bills to increase substantially.

Refrigerant Leaks

When was the last time you had your AC refrigerant charge tested? If you can't remember the date, month, or year, chances are high you might need an AC recharge. While air conditioning systems are not meant to run out of refrigerant, they can develop leaks that result in the loss of refrigerant charge.

A low refrigerant level means your AC system's cooling output may decline significantly. 

When maintained regularly, your residential air conditioning system should serve you reliably and efficiently. Unfortunately, you can never rule out the risk of AC failure, even with regular AC maintenance. If you experience any issues with your home's cooling system, never hesitate to call an HVAC contractor for air conditioning repairs.
