AC Repair Warning Signs: Strange Sounds
Living comfortably in hot areas heavily relies on your air conditioning system. Given the consistently high temperatures for much of the year, your AC will be working hard. So, it’s crucial to take every possible measure to ensure your system operates smoothly and reliably. It includes addressing any issues with your air conditioner as soon as you notice them.
While encountering a malfunctioning air conditioner is always unfortunate, the silver lining is that there are typically warning signs that indicate your system is struggling. One of the most common indicators is unusual operating noises. If your air conditioner suddenly starts making unfamiliar sounds, don’t dismiss it as insignificant. It could indicate a sign that your AC needs immediate repairs. Here are the signs to watch out for.
Identifying Strange AC Sounds
New or Loud Sounds Indicate a Problem
A common mistake many homeowners make is assuming that if their air conditioner runs, it must run properly. It is only sometimes the case. Many issues can persist for a long time before the system breaks down. Ignoring unusual sounds while your system is still functioning will only allow existing problems to cause more extensive damage.
Strange noises are often the first sign that something is amiss with your air conditioner. For example, a grinding noise could indicate a problem with the motor bearings, while a hissing sound might point to a refrigerant leak.
If not addressed promptly, these issues can lead to significant damage and potentially costly repairs. By paying attention to and investigating unusual sounds, you can catch problems early and avoid more extensive damage to your system.
Furthermore, consistent maintenance and early intervention can significantly extend the lifespan of your air conditioning unit. Addressing issues as soon as they arise keeps your AC running smoothly and ensures it operates at peak efficiency, saving you money on energy bills. Taking strange AC sounds seriously and acting quickly protects your investment and maintains a comfortable home environment.
Common Strange AC Sounds
Banging Sounds
A loud banging sound from your air conditioner likely means a loose component rattles inside the unit. The indoor unit might also be off-balance. This noise clearly indicates something is wrong and needs immediate attention to prevent damaging your AC further.
Not addressing this issue can lead to significant wear and tear on your unit, potentially causing expensive repairs or even the need for a complete replacement. It’s essential to have a professional technician inspect and secure any loose parts promptly.
Clicking Sounds
Clicking noises are common when your air conditioner starts up or shuts down and are related to the electrical components. It is usually normal. However, if the clicking is constant, it likely points to a problem that requires professional repair. Persistent clicking could indicate issues with the thermostat or a failing control panel.
Additionally, continuous clicking can indicate a relay issue or a malfunctioning capacitor, which a qualified technician should address to prevent further electrical problems and ensure your system runs smoothly.
Screeching Sounds
If your air conditioner emits a screeching noise, it could mean it needs lubrication. However, it might also indicate a more serious issue, such as high internal pressure. Screeching sounds often point to problems with the fan motor or a compressor experiencing too much pressure.
If left unresolved, these issues can lead to motor failure or significant damage to the compressor, which are expensive repairs. Prompt attention from a professional can diagnose the exact cause of the screeching and implement the necessary repairs to keep your AC running efficiently and safely.
Addressing Strange Sounds
The Importance of Prompt Action
While some noise level is expected, new and unusual sounds should always be taken seriously. We rely heavily on our air conditioners, so addressing any minor problems before they develop into major ones is vital. Ignoring these warning signs can lead to a cascade of problems that affect your system’s overall performance and reliability. Early intervention can prevent further damage and maintain the efficiency of your air conditioning unit, ensuring you stay comfortable throughout the year.
Additionally, addressing issues promptly can help you avoid emergency repair costs. When problems are caught early, they can often be fixed quickly and inexpensively. By taking action at the first sign of trouble, you protect your investment and ensure your air conditioner operates at its best

Benefits of Timely Repairs
Addressing strange AC sounds promptly can prevent minor issues from turning into major, costly repairs. Ensuring your air conditioner functions correctly enhances its efficiency and lifespan. Regular maintenance and timely repairs save you from the inconvenience and expense of a total system failure. Keeping your air conditioner in top shape improves indoor air quality, as a well-maintained system is less likely to harbor dust, microbial growth, and other allergens.
Timely repairs can also lead to significant energy savings. When your air conditioner operates efficiently, it uses less energy to cool your home, reducing utility bills. Over time, the savings on energy costs can offset the expense of regular maintenance and repairs. Additionally, a well-maintained air conditioning system is better for the environment, as it consumes less electricity and reduces your carbon footprint.
By incorporating these practices into your regular home maintenance routine, you ensure that your air conditioning system remains a reliable and efficient component of your home’s comfort system. Regular attention to your air conditioner prevents costly repairs and contributes to a more comfortable and healthier living environment.
Preventive Measures
Regular Maintenance
Routine maintenance is essential to prevent strange AC sounds and other issues. Regular check-ups help identify potential problems before they escalate, keeping your system in top condition.
Homeowner Tips
As a homeowner, you can take steps to maintain your air conditioner. Keep the area around your outdoor unit free of debris, replace filters regularly, and stay alert to any changes in your system’s performance.

This appointment was to check that my heater is working properly before winter arrives.





Today the HVAC team came with a coil cleaning and suggested maintenance. Steven and Jonathon were top notch. Courteous, professional and informative. If you want it done right, get Goettl.

Maintenance, I have 3 (three) units, Brandon
Completed the work in a reasonable amount of time, and gave a comprehensive overview
Of conditions , He was very courteous, with good appearance , and was careful of surrounding furniture.
I would rate him, Excellent.




















Given the extent of the work I need to get multiple quotes and some companies insist on expensive trip charges (one up to $500) to have a “specialist” assess before providing a quote for the work.
These guys were timely, transparent and uncomplicated. I appreciate Shane for quickly putting together an estimate before even leaving the house, providing multiple options at various price point and without pressure of upfront commitment.
I would feel confident moving forward with these guys. Thank you Shane!

This past week our service technician was Andrew Morgan and he is such a friendly, knowledgeable, and skilled technician. He spent time making sure the job was done correctly and he explained it in terms that I could understand. Not only is our unit functioning even better than before, I also gained knowledge of how the system works.













I highly recommend Goettl as this is the second time l've used them in less than a year. (2 seperate issues)... and I highly recommend them..anytime and anyday.
They have exceeded to top any expectations I could have ever had with any company.


Jerry also noticed our water pressure was low after flushing toilet then trying to wash hands in bathroom sink which were so he suggested a new pressure regulator as we have had a new better water conditioning system installed. We now have the best water pressure even when using a shower and kitchen sink faucet at the same time. Also Jerry is a master plumber and we appreciate his knowledge and experience. Will definitely call Goettl again when a plumber is needed.
Ralph & Kathy Lesmeister



Darean Guerra today. He arrived on time and took the time to explain what he was going to do. He was very knowledgeable which helped me trust what he was doing. He left his work area clean. I am very pleased with his work.

The company is installing a tankless heater and the customer service is outstanding.
I recommend Geottl to all!
