Common Reasons For AC Repairs

Air conditioning is one of the most important modern conveniences, allowing people to stay cool throughout the summer. But sometimes the cooling system may encounter problems that need AC Repairs.

If your air conditioner constantly runs, it could be due to a faulty thermostat, dirty coils, or ductwork that restricts airflow. Troubleshooting these issues can often help you avoid a replacement.

Dirty Evaporator Coil

A dirty coil is one of the most common Air conditioning Repairs for a loss in AC performance. A dustcoated coil cannot absorb heat as efficiently as a clean coil, so the air conditioner must run longer cycles to achieve the same cooling effect. This puts more strain on the system, which can lead to additional wear and even system breakdown.

A dirty evaporator coil also creates condensation that can form frost or ice when the system is running. This prevents the coil from effectively absorbing heat, and eventually stops it from working altogether. As the ice on the coil builds, it can damage the evaporator coil itself or clog the drain line and cause water leaks. Keeping the evaporator coil and fins clean is an important part of preventative maintenance, and a professional technician can use specialized cleaning techniques to ensure the coil and fins remain as clean as possible. The professional will use a vacuum cleaner attachment to remove loose dirt, and may follow up with a

degreaser or commercial coil cleaning solution.

Dirty Compressor Coil

The compressor coil is located in the outdoor unit and has a lot of exposure to the elements over time. This can give contaminants such as dirt, dust, leaves, bird droppings, insect shells, fungi and other organic matter a chance to find their way into the system and cause an issue.

Dirty condenser coils prevent the refrigerant from releasing heat to your home, so it has to work harder to achieve your desired temperature. This will put unnecessary strain on the system and shorten its lifespan.

Your dealer will remove the evaporator and condenser coils and clean them. They’ll use a brush and fin comb to remove the loose dirt and debris from the coils, then either allow them to drain or lightly rinse with a hose. This will help prevent damage to the thin metal fins that are found on the coils. They can also squirt a foam cleaner on the coil surface to help reduce future buildup.

Damaged Coolant Lines

Coolant lines must be free from kinks, sharp edges, and other damage that can restrict coolant flow. This can reduce cooling efficiency and cause the engine to overheat. It also causes a drop in heater performance. If the needle on the engine temperature gauge moves toward "hot," it's time to call in a professional.

Typical signs of coolant line damage are a hardened, glossy outer surface with cracks. A slight swelling is another sign of internal damage. Chemical damage from ECD (electrochemical degradation) or exposure to oil and other fluids can weaken the hose material, eventually leading to failure.

If the hoses are damaged, it's important to replace them and properly route the new hoses. Be sure to use a quality replacement hose made from EPDM rubber, which is not attacked by ozone. You should also consider using beaded connectors, which are less likely to slip off. This can help you avoid costly AC repairs in the future.

Damaged Blower or Fan

The blower or fan is responsible for circulating air throughout your Air conditioning Installs Denham Court, which is crucial to cool your building. If you start experiencing poor airflow from the vents, a broken blower motor may be to blame. Some of the most common symptoms include:

A whirring sound that gets louder as you increase fan speed can indicate that something is loose or damaged in the motor. You should turn off your AC system at once if you hear rattling sounds or smell electrical burning coming from your vents.

If your blower motor is making a squealing or howling noise, the bearings may need to be lubricated. A professional should examine the blower motor to determine if it needs to be replaced or if it can simply be repaired. Oftentimes, the problem is isolated to a single component within the blower motor, so it may just be a fuse, relay or control board issue. In this case, your technician should test each component using a multimeter.
