Having a functional AC system can make a world of difference to your home. But like any other machine, your air conditioner can develop issues over time that require professional assistance.

While there are some things you can handle on your own, such as changing filters or resetting a tripped circuit breaker, other problems need the attention of an AC repair expert. Contact AC Repair Orlando now!

The compressor is one of the hardest-working parts of any AC system. Over time, it can develop issues that reduce its efficiency and cause malfunctions. Identifying these problems early on helps prevent costly repairs down the line. Regular maintenance can also minimize the amount of wear and tear that the compressor undergoes.

The compressor converts the liquid refrigerant into a gas, which it then transports to the condenser coil. Here, the high-temperature gas releases its heat and turns back into a liquid. The process is essential for the system’s functionality. To perform this function effectively, the condenser coil must be free from dirt and debris. A dirty or clogged condenser coil will hinder the refrigerant’s ability to release heat.

Most residential air conditioning systems use either a hermetic or semi-hermetic compressor. Hermetic compressors are more expensive, but they offer greater energy efficiency than semi-hermetic models.

There are many signs that the compressor may need repair, including:

Reduced cooling effectiveness: If the air isn’t cold or if it takes longer than usual to cool the home, this is a sign that the compressor isn’t working properly. This could be caused by a number of things, including a faulty fan, a low refrigerant level, or a thermostat issue.

Strange noises: If you hear strange rattling, banging, or buzzing sounds, this is another indication that the compressor isn’t functioning correctly. The noise could be caused by a broken part, loose belt, or clogged filter.

Humidity: High humidity can make your home feel uncomfortable and stale. It can also lead to mold and mildew, which can have serious health impacts for people with respiratory conditions or allergies.

A low refrigerant level can lead to poor cooling, but recharging the system with more refrigerant is usually an easy fix. Your technician will start by determining how much refrigerant the system needs and assessing its operating pressures. Then, they’ll recharge the system with the proper amount of refrigerant and test for leaks. The last step involves replacing the compressor contactor, which is typically a quick and simple procedure.

Condenser Coil

Your air conditioner cools your home by removing heat from indoor spaces and transferring it outdoors. The evaporator coil and condenser coil are both vital for this process. However, homeowners often forget that these coils need to be cleaned for proper function. Without regular maintenance, your AC will have to work harder to cool your home, leading to a shorter lifespan and higher repair bills than necessary.

The evaporator coil absorbs heat from indoor air and transfers it to the outdoor condenser unit, which releases the low-pressure vapor refrigerant into the outdoor environment for cooling cycles. The condenser coil, located in the outdoor unit, is responsible for heat release and air flow, but it can be infiltrated by twigs, leaves, dirt and other debris, causing blockages that interfere with efficient heat dissipation.

Dirty or blocked coils prevent heat exchange and increase the operating pressure of the compressor, which leads to high energy consumption and increased risk of failure. A professional can remove dust from the coils and ensure that the copper tubes remain free of corrosion, enhancing heat transfer efficiency and preventing premature system breakdowns.

As an added benefit, keeping your evaporator and condenser coils clean will help your air conditioning system last longer. If you’re not comfortable performing DIY maintenance or would like an expert to assess your home’s coils and additional components, contact a Lex AC technician today.

Blower Motor

When the thermostat signals the HVAC system to activate, the blower motor turns on and begins circulating heated or cooled air throughout your home. This is one of the most important parts of your air conditioning, so regular AC maintenance and prompt repairs are key to ensuring it stays in good working order.

The blower motor sits inside the furnace compartment, close to the air filters. This makes it easy for a technician to check both components at the same time, especially if you suspect that your blower motor isn’t working because of dirty air filters. A blown fuse is another common problem that can prevent your blower motor from working. Fuses protect electrical circuits from an excessive current, so if a wire becomes hot from friction or dirt, it will melt the fuse and cut power to the motor. When a fuse blows, it’s important to replace it right away to avoid further damage.

Blower fans can also stop working because of a faulty electrical connection or physical damage to the motor or fan itself. The latter problem is most often seen with older AC units, where dust and other debris can build up on the fan and motor. This can cause the motor to overheat, which can lead to mechanical failure and emit an unusual odor. Modern blower motors have electronics that prevent them from overheating, so this issue is less common than it used to be.

A broken blower motor can lead to inefficient ventilation and increased energy bills. It can also have serious health consequences, particularly for elderly people or young children who might not be able to regulate their temperature as effectively. In sweltering conditions, the body can’t cool itself as easily, which can lead to heat exhaustion and even death in some cases.

The good news is that most of these problems can be avoided with routine maintenance and timely repairs. By choosing an AC repair company with experience and credentials, you can be confident that your system will continue to work properly.

Contactor

AC repair isn’t just about fixing a machine—it’s also about ensuring healthy and comfortable living environments. A broken or malfunctioning AC system can have adverse effects on indoor air quality, often going unnoticed until serious health issues develop. For example, a poorly functioning AC can lead to inadequate air circulation, which in turn creates the perfect environment for mold growth. Mold spores, once airborne, can be inhaled and cause respiratory problems and allergies. In addition, a musty odor can permeate the entire home.

Moreover, AC repair involves analyzing the performance of the entire cooling process—converting a refrigerant between gas and liquid in the compressor, condenser coil, expansion valve, and evaporator coil—and ensuring it is operating as efficiently as possible. In this regard, tools like thermal imaging cameras become indispensable, allowing technicians to quickly and non-invasively identify anomalies in the system. For instance, a thermal image showing an area with unexplained cold spots can indicate a refrigerant leak or blockage, while a hot spot could point to an overworked component.

Another important tool in the arsenal of an AC technician is a digital multimeter, which can be used to diagnose a variety of electrical issues within an AC unit. These devices can identify voltage, current, and resistance, providing a comprehensive insight into the internal workings of the AC. In particular, digital multimeters are a vital tool in identifying issues with the contactor, a device that connects electrical power to the electromagnetic coil of an AC compressor.

Another important tool in the realm of AC repair is an anemometer, which can be used to assess the speed and volume of air flow through an AC system. This allows technicians to identify any issues that may be affecting the system’s ability to cool a room effectively, such as a declining performance in the evaporator coil, a dirty evaporator coil, or an expansion valve.
