Refrigerants are crucial to your air conditioner’s operation, absorbing heat from the interior of your home and releasing it outdoors. If the refrigerant level becomes low, however, it will not be able to perform this vital task, and your system may not cool your living space as effectively. To avoid this issue, there are several signs that you should watch for.
One of the most obvious signs of low refrigerant is if your air conditioning system blows warm or lukewarm air. Since the air conditioning system relies on refrigerant to absorb heat, without it, your cooling system will not be able to perform as intended.
Another sign of low refrigerant is if you notice that your energy bills are rising higher than usual. This is due to the AC unit having to work harder to counteract the loss of cooling capability as a result of low refrigerant levels. The resulting strain on the compressor’s electric motor can cause it to overheat, and replacing this component will be an expensive repair.
A third sign of low refrigerant is a hissing or bubbling noise from your air conditioning unit. If you hear this sound, it is a good indication that the refrigerant line has a leak that needs to be repaired immediately by a professional air conditioning technician.
Leaks are common in many older air conditioners, as the metal parts of the unit can rust and develop small cracks or holes over time. When this happens, the refrigerant will begin to escape and will not be able to cool your living space.
The best way to keep your refrigerant levels up is through regular maintenance by a professional air conditioning service. They can detect and fix small problems before they grow into major ones, ensuring that your AC is able to keep up with Tulsa’s summer heat and humidity. By understanding the key indicators of low refrigerant, homeowners can take prompt action and ensure that their systems operate at peak performance throughout the summer. For more information, contact a local air conditioning company.
Unusual noises
Depending on the type of noise you hear, it could be a sign that your AC unit is starting to experience a problem. For instance, a hissing sound typically points to a refrigerant leak. If left unchecked, this can result in the compressor straining under high pressure until it fails and requires professional attention to seal the leak. A squealing sound is another possible indicator that your blower fan motor bearings are wearing down. In such a situation, the bearings will need to be replaced before the motor itself begins failing, which would require a complete replacement of the blower fan.
Clicking sounds typically occur during the startup process, as the unit attempts to start up and begin cooling your home. If the clicking continues to happen during a cooling cycle, this can indicate that there is a problem with the contactor relay switch, which is meant to communicate with the thermostat and turn on the outdoor unit.
A buzzing sound is often a sign that there is an electrical problem within the unit, such as a broken capacitor or an overloaded compressor. In such a scenario, you should turn off the unit immediately and call a professional for repairs as soon as possible to prevent further damage to your system and potential electrical fires.
Rattling sounds can be the result of loose parts inside the unit or debris, such as leaves and twigs that have found their way into the unit. A rattling sound can also indicate that the blower fan is beginning to fail, which will need to be replaced before the entire motor starts to wear out.
If you hear any of these unusual air conditioner noises, it’s best to consult with a professional right away. This ensures that minor issues don’t escalate into major problems, safeguarding your unit for a long life and keeping your home cool and comfortable.
Won’t turn on
Often, the simplest issues are the most overlooked, and it’s easy to jump to conclusions when your air conditioner won’t turn on. Before you call a professional, make sure the unit is plugged in and that the switch is set to “on.” Additionally, check to ensure the indoor shutoff switch (for split systems) or the outdoor switch (for central systems) is not in the “off” position. These switches are typically located near the unit in a closet, crawl space, or attic and can easily be switched off unintentionally during daily activities.
Another potential reason your AC won’t turn on is that the circuit breaker has been tripped. This is a safety mechanism designed to prevent overloading of the electrical system by cutting power if there’s an issue. To reset the breaker, locate your home’s electrical panel and look for the breaker labeled “AC.” Once you find it, flip it to the on position and test the system. If the breaker trip again, it may be due to a more serious issue, such as an overloaded circuit that requires professional help.
A clogged drain pan or line can also prevent an AC from turning on. The system creates condensation that exits through a drain line, and if this line becomes full or clogged, it will trigger the safety switch and turn off the unit. Clearing the drain line with a wet/dry vac or pipe snake can usually fix this problem.
Finally, if your fuses are regularly blowing, it may be due to a capacitor issue. This component is necessary for the AC to start and run, but if it begins to wear out or is damaged, it won’t be able to provide power to the condenser and the cooling process won’t begin.
A professional HVAC technician can determine what’s causing the issue, such as low refrigerant levels or a faulty fan, and repair or replace it. It’s important to address these issues quickly to avoid more extensive and costly repairs in the future. So, if you are experiencing these issues, don’t hesitate to contact us for an AC repair.
Drainage issues
As air passes over the evaporator coils, it cools and loses humidity. The condensation drips off the coil and into a drain line that exits the AC unit. This drain line can become clogged with dirt, dust and other debris. The best way to prevent this is with regular maintenance by a professional HVAC technician. During this service, they will clean off the coils and ensure that the drain line is free of debris and clogs.
If you notice water pooling around your AC unit or have a wet spot on the ceiling, this is a sign of a clogged drain line. Water pooling around the unit can lead to water damage and mold growth inside the home. It is important to have the problem fixed right away by a trained professional to avoid extensive damage.
The drain line can also become clogged due to a frozen evaporator coil. When the coil thaws, the excess water can overwhelm the drain line and cause a clog. The clog can also allow algae and mold to grow, leading to respiratory issues for your family.
A blocked drain line can also reduce your system’s ability to cool the house. If the clog is severe, it can even shut off your entire air conditioning system.
Other common drainage problems include a damaged condensate drain pan or improper installation of the air conditioner. This can lead to a flooded basement or water damage to the ductwork and roof.
It is also important to keep your air filters regularly cleaned and changed, as this will improve the flow of air through the system and help to prevent the clogging of the drain lines. A dehumidifier can also be used to lower indoor humidity levels, reducing the strain on your AC system.
Many of these common AC repair issues can be prevented with regular maintenance by a professional HVAC technician. These services can include checking refrigerant levels, inspecting the drain pan and line, cleaning the evaporator coils and ensuring proper airflow through the ductwork. Performing these routine tasks can save you money on your energy bills and ensure that your air conditioner is working properly to provide comfortable temperatures in your home.
