Air conditioning service typically involves inspecting the system for issues. Then, technicians can perform optimizations like cleaning dirty filters and checking refrigerant levels.
Your thermostat’s control center must remain clean to transmit the cooling signal to your condenser. If the wires get corroded, your AC might stop working! This is a pretty serious AC Repair Round Rock TX issue.
One of the biggest problems that air conditioners can experience is water leaks. These pooling moisture can cause damage to the equipment and, if left untreated, can lead to mold growth and other health issues throughout the home. If you notice any water around your air conditioning unit, call a professional immediately to determine the cause and make any necessary repairs.
AC leaks can occur for a variety of reasons, including improper installation or maintenance, and age. An older AC system may have a drain pan that is missing or cracked, and this can allow water to seep into the home. A clogged drain line can also be the culprit of an AC leak, so it is important to keep this clear with regular cleanings.
If you notice any moisture or puddles around your AC unit, shut it off immediately to prevent further damage. Remove any standing water and use old towels or moisture-absorbent rags to soak it up. If you can, try to elevate the unit so that it doesn’t flood and damage any electrical components. You can also have a professional check the grading of the land surrounding the unit to ensure that water is directed away from the AC and your home.
During the cooling process, the evaporator coil pulls excess humidity from the air and converts it into condensation. This condensation usually drains through a hose into the unit’s drain pan and out of the home, but if this drain line is disconnected or severed, it can lead to a leak. If this is the case, a professional can reconnect or replace the drain line and correct the problem.
Dirty air filters can also contribute to AC leaks, as they can block the evaporator coil and prevent the proper flow of condensation. Be sure to clean or replace your filters regularly to avoid this issue. You can also have a professional clean the condensate drain line to help prevent clogs and ensure that the drainage hose has an unobstructed path. An experienced technician can also check the float switch to ensure that it is working properly.
Unusual Noises
While Edgar Allan Poe may have had a different take on the tapping of a ghost at the chamber door, homeowners who hear unusual noises from their AC units need to treat them as serious warning signs. Ignoring these strange noises can result in costly repairs, system failures, and a host of other problems that are best avoided by being proactive.
Rattling Noises
When you hear a rattling sound, it usually indicates that there are loose parts inside your unit. These could include anything from a fan bearing to a compressor motor. If you suspect that this is the case, turn off your air conditioner and inspect the unit visually with the power off. Loose components should be tightened to prevent further damage.
If the rattling is more persistent, it is best to call a professional to ensure that any loose parts are properly secured and that no further damage is caused. A technician will also be able to address any debris that may be stuck in the evaporator coils or condenser fan motor.
Clicking Noises
A clicking noise from your AC unit often indicates an electrical problem, such as a tripped circuit breaker or fan motor issue. This is a serious safety concern and should be addressed by a professional. This type of issue often involves high currents and needs to be resolved as quickly as possible.
Squealing Noises
Squealing noises typically indicate that the blower belt or fan blades need to be replaced. However, since newer AC units use direct-drive motors that don’t need belts, this is less of a concern with these models. If the squealing is from the indoor portion of your unit, it may be an indication that you have closed off air vents in certain rooms. This changes the pressure of the ducts and can cause them to loosen or develop cracks.
Thumping or banging noises can indicate a number of issues, including a blocked condensate drain line or a damaged fan motor mount. This is another reason why you should regularly clean your condensate drain line to prevent blockages and avoid costly repairs. Unbalanced fan blades can also create this type of noise. Ensure that they are properly balanced to reduce the vibration and improve efficiency.
Thermostat Errors
A thermostat is a crucial piece of the AC system, and it can be frustrating when it stops working correctly. Several factors can cause a thermostat to stop functioning, including incorrect placement, dirty sensors, and power supply issues. A professional technician can inspect the unit and determine the cause of the issue.
The first step in troubleshooting a malfunctioning thermostat is to check the batteries. If the display is blank or dark, the batteries need to be replaced. Next, check the circuit breaker to ensure that it hasn’t been tripped. If you have a wired thermostat, you should also make sure that the wiring connections are secure and properly seated. In addition, dust and dirt can interfere with temperature sensors, so it’s a good idea to clean the unit periodically.
Another common problem with thermostats is that they are located too close to hot sources, like ovens or appliances. This can cause the thermostat to read false temperatures and cause the air conditioner to run unnecessarily. It’s also important to keep the thermostat away from drafty areas and direct sunlight. If the room is too warm, it may be necessary to change the thermostat’s settings or install additional insulation to help regulate the home’s temperature.
Many older thermostats are prone to errors, especially after prolonged use. A professional can replace the device to restore function and prevent strain on your heater and AC.
Sometimes, error codes on a thermostat can indicate an issue with the unit’s software or firmware. In these cases, it’s a good idea to consult the user manual for the specific model of your thermostat. They can provide detailed instructions for testing and resetting the thermostat. Additionally, electrical problems can also affect the functionality of a thermostat. If the unit is receiving faulty power, it could be experiencing memory or firmware errors. Moreover, if the thermostat has stopped functioning altogether, this may indicate a faulty sensor or a worn-out battery. A professional can test the unit for faulty components and perform repairs to fix the issue.
Mold Growth
Mold can thrive in humid areas where there’s a combination of three key elements: moisture, nutrients and oxygen. It can grow in rooms, walls, and ceilings, as well as in HVAC systems and vents. If left unchecked, mold can spread throughout your home and lead to a variety of health issues. These include respiratory illnesses, allergies, serious health problems for those with compromised immune systems, and even death in severe cases.
A moldy AC can also negatively impact indoor air quality and cause damage to the system. If your air conditioning unit has a mold problem, it will need to be removed and cleaned thoroughly. A professional technician should clean and disinfect the evaporator coils, filters and internal air ducts to remove the mold, as well as address any HVAC problems that could encourage future mold growth.
If you suspect that you have a moldy AC, call an HVAC contractor right away. They will be able to identify the source and help you make repairs.
The most common problem that can promote mold in your AC is a clogged condensate drain line. Moisture from your evaporator coils is usually drained through the condensate drain line to the outside of your house. If the drainage line is clogged, it will overflow and become moist, providing the perfect environment for mold to thrive.
Another common problem is the lack of ventilation in your ductwork. It is important for the ducts to be properly sealed and insulated, or else mold spores can travel from one part of your house to the other through the ductwork. The spores can then land on the evaporator coils, or in the internal air ducts, where they will grow and cause further problems.
Using a dehumidifier can help you eliminate excess moisture in your home, and regularly cleaning the evaporator coils, filters, and internal ductwork can starve mold spores of their nutrients. Keeping your AC working properly will ensure that you get the best performance out of it. When you need an AC tune-up, give us a call at Advantage Air Mechanical.
