Realizing your AC compressor needs a replacement before it’s too late saves you from disappointment and frustration. Check out these 5 warning signs to know better about your AC unit.
Knowing that your air conditioning unit is going bad beforehand saves you from last-minute inconvenience. Yes, an HVAC system tells you in different ways before it actually breaks down. So, how to know if your AC compressor is bad?
A bad compressor makes weird sounds when you turn it on and blows warm air, indicating reduced efficiency. Upon holding hands in front of your AC unit, you might notice less air flowing out of the vents, often because of refrigerant leakage. The circuit breaker frequently trips if your compressor is burnt out.
Some of these issues are manageable and need quick repair services to get going with your routine. However, others require the installation of a new compressor or HVAC system. Keep reading to know when you should consider the repair and replacement option.
5 Symptoms Of A Bad AC Compressor
Observe your air conditioning unit and if it ticks more than one of the following symptoms, you must contact a technician.
1. The Air Doesn’t Feel Cold Anymore
You have been using your AC for a while and know how it feels at 16°C and 24°C. Therefore, you can immediately notice the drop in performance as it takes longer than expected to maintain the optimal room temperature.
However, it’s not always the compressor that is responsible for reduced airflow and warmer air. Other contributing factors are:
- Dirty filters,
- Clogged condenser, and
- Poorly functioning fan
You can tackle these minor issues with regular maintenance and routine inspection.
If your AC performance keeps declining despite addressing these factors, there is a strong chance that the compressor is the primary reason. It may be running out of refrigerant or there may be a leakage disrupting the normal functioning.
2. You Hear Weird Noises Coming Off
Unusual, weird noises start coming from your AC while it is on, signalling that damage has gone beyond DIY maintenance. Since the source of the noise can vary, you need a technician who knows how to detect a faulty compressor and find out where the problem lies.
When your AC compressor relay system goes out, the unit makes a clicking sound but fails to kick on. While a clicking sound is normal, the HVAC system sometimes produces loud buzzing sounds. This indicates loose components, a failing motor, or electrical issues.
3. The Unit Starts Up With Vibration
There might be something more than poor electrical work or motor failure, causing sharp rattling and rumbling noise. Over time, the machine goes through wear and tear resulting in failure of mounts and detachments.
The loose components moving inside the system keep hitting the frame, producing noise and vibration. This needs the immediate attention of a professional as DIY fixing can be dangerous.
4. You Can Smell Leakage
Leakage is one of the different telltale signs pointing out that your house AC compressor is going bad. You may run into 3 types of leakage problems:
- Water leakage: Excessive moisture or puddles become noticeable around the unit. It occurs due to clogging in the drainpipe.
- Oil leakage: Oil starts dripping from the condenser when seals are broken.
- Refrigerant leakage: It’s often combined with oil leakage due to corrosion or puncture in the tubing and extends the cooling cycle
Important: Freon leaks from AC produce a slightly sweet, chloroform-like smell with the formation of ice crystals and is highly toxic. Exposure to a significant amount leads to freon poisoning.
5. The Circuit Breaker Keeps Tripping
Identifying whether the issue is in the outside breaker or the AC compressor isn’t easy if you are running multiple devices on a single breaker. Ideally, you must keep your electric appliances running on different breakers for evenly distributed power and load.
The frequent tripping of the air conditioning circuit breaker hints that the AC compressor is burnt out and drawing extensive power. In that case, the compressor becomes overheated and handling it yourself isn’t safe.
How Long Do AC Compressors Last?
AC compressors usually last for at least 10 years. However, with appropriate use and maintenance, they can continue to work efficiently for up to 15 years.
How To Prevent AC Compressor Failure? Routine Maintenance Tips
By following these maintenance tips, you can extend the lifespan of your AC compressor:
- Clean or Replace Air Filters: Dirty filters restrict airflow and force the compressor to work harder. Check and replace air filters every 1–3 months.
- Inspect and Clean Coils: Both the evaporator and condenser coils can accumulate dirt over time. Clean the coils annually to maintain efficient heat exchange and prevent strain on the compressor.
- Check Refrigerant Levels: Ensure the refrigerant levels are correct. Low levels can cause the compressor to overheat. Have a professional check and adjust the levels if necessary.
- Clear Debris Around the Unit: Keep the area around your outdoor unit free of leaves, grass, and other debris to ensure proper airflow.
- Inspect Electrical Components: Periodically check the wiring and electrical components for signs of wear or damage. Faulty wiring can lead to compressor failure.
Final Words
You might have heard several times that the compressor is the most expensive part of your air conditioning unit and its repair cost is quite high. Considering this, your AC compressor often sends you alerts in the form of different signs indicating that something is going wrong.
As soon as you notice changes that don’t align with your compressor’s usual working, reach out for expert advice. Contacting a professional HVAC technician at the first sign of trouble can save you from costly repairs and replacements.
FAQs
Can I Run My AC With a Bad Compressor?
Running an AC unit with a bad compressor isn’t possible as it usually ceases to cool down the temperature. Call for an inspection when you notice the first signs of your compressor going bad. Otherwise, you would end up with a nonfunctional AC that’s too much to bear in summer.
How Do I Know If I Need A New AC Compressor?
You need a new AC compressor if the current one makes strange noises and has reduced airflow with warmer air circulating through the room. While some issues are repairable, you have no option but to replace your compressor if it has just stopped working after frequent tripping of the circuit breaker. Consider the age of the unit also, as older units might not be worth the investment in repairs.
How Much Does It Cost To Replace An AC Compressor?
Replacing an AC compressor typically costs around $1100 to $3000. This cost includes both the parts and installation charges. However, it is for a central air conditioning unit. If you have a mini-split or window AC, the cost can be as low as $800.
