Defective AC Compressor
At Ambrose Air Inc, we know that the compressor is the heart of the refrigeration circuit. It pumps and pressurizes the refrigerant to move it through the A/C system. Compressors work hard and run hot, up to several hundred degrees and several hundred pounds per square inch of internal pressure. They rely on only a few ounces of lubricant to keep their parts moving. If the lubricant is lost because of a leak, or the lubricant breaks down due to contamination, the compressor will not last. Sooner or later, the compressor will call it quits, but it also is the most commonly misdiagnosed component in the AC system.
Common Symptoms Of a Defective Compressor
The most common symptom of a compressor failure (besides no cooling) is a seized compressor. It will not turn when the magnetic clutch engages, and you may hear squeals of protest from the drive belt. Or, the belt may have already broken or been thrown off its pulleys.
Loss of lubrication is unquestionably the most common cause of compressor failure. This can happen when there is a refrigerant leak somewhere in the system that allows refrigerant and oil to escape. Typical leak points are hoses, hose and pipe connections (O-rings and flange gaskets), the evaporator, condenser or the compressor shaft seal. An electronic leak detector or dye should be used to find the leak so it can be repaired.
A restriction inside the A/C system can also starve the compressor for oil. Oil circulates with the refrigerant, so if the orifice tube or expansion valve is blocked it may cause the compressor to run dry and seize.
Even if a compressor is still turning, it may have to be replaced if it is leaking, making excessive noise or not working correctly. Some compressors are naturally noisier than others, but loud knocking noises can sometimes be caused by air in the system (the cure here is to vacuum purge the system to remove the unwanted air, then to recharge the system with refrigerant). Metallic noises and bearing noise are usually signals that the compressor is about to fail.
Poor cooling can also be caused by a lot of things other than a bad compressor, so do not replace the compressor until you have ruled out other possibilities such as a low refrigerant charge, too much oil in the system, air contamination, a clogged condenser, plugged orifice tube, inoperative electric cooling fan, etc.
FAQ ON DEFECTIVE AC COMPRESSOR
How common is it for an AC compressor to fail?
The AC compressor failure problem is common when needing Orlando AC repair. Issues like too little oil or installation errors increases chances of the unit failing.
What are signs to watch for?
An air conditioner compressor may start to make strange noises. It can sound like it’s having a hard time getting started up. It may even begin to lose some of its cooling power as this part starts to gradually failure.
Why is my AC not cooling as effectively as it used to?
Losing cooling capacity is a common problem as the compressor starts to fail. The compressor may have a hard time maintaining the appropriate level of pressure. Once it starts to lose its discharge capabilities, it’s better to replace this part since performance will continue to decline.
Why is my AC cycling on and off?
Shutting on and off is caused by the system’s inability to compensate for system deficiencies. The AC could be cycling on and off because the compressor’s capacitor is defective. The compressor could start to fail because it’s utilizing a higher level of amperage than normal. If the system begins to overload, it could end up cycling off. Low refrigerant charge and clogged filters are additional causes that can lead to short cycles.
Why is my AC not cutting on at all?
The compressor may be badly damaged. Replacing this part is necessary in order to get the unit to function normally again.
Is there anything I should do after replacing the compressor?
You should flush the compressor after replacing the part. The hoses should be thoroughly flushed. Over time, the debris can clog up the condenser and lead to extensive blockage in the tubes. The blockage not only diminishes performance, but it also leads to compressor failure. If you have an older system, you will have an easier time flushing the system if the system contains a serpentine-style tube and fin condensers. You also want to make sure that you have removed all of the debris from the old compressor to prevent the new system from failing.
What are the most common reasons for this type of failure?
Systems can fail due to neglect. The system has to be properly maintained. Something as simple as having too little oil in the system is enough to cause the system to malfunction. Parts incorrectly installed can cause the system to fail.

What is the SEER Rating?
The SEER (seasonal energy efficiency ratio) is how the efficiency of your heating and cooling equipment is measured. The SEER is the amount of cooling your system will deliver per dollar spent on electricity, as compared to other systems. For example, a 3-ton unit may have a SEER efficiency rating of 13, 14, or 15. The higher the SEER the more efficient the system will be. The SEER rating of any given unit can range anywhere from 13 to 21.
Which brand of AC is the best?
Why is the SEER rating on the Energy Guide different than what my dealer quoted?
Why should I have regular (or preventative) maintenance? And how often should I have it performed?
Your heating and cooling systems work incredibly hard to perform their functions for your home everyday. The constant stopping, starting and continual operation can wear down any machine if the proper care and maintenance is delayed. However, by performing regular maintenance, you can maximize the lifecycle of your heating or cooling unit and guard against many common equipment failures. Preventive maintenance inspections performed on a regular basis can uncover leaks, rust, rot, soot, frayed wires and corroded electrical contacts that the naked eye may not notice. You should have maintenance done on your system regularly to ensure maximum efficiency and allow prevent possible problems that may occur in the near future.
What equipment requires regular (or preventative) maintenance?
At least twice a year heat pumps and air conditioners require a professional tune-up. Because gas-fired equipment functions with greater efficiency, they only need to be serviced every other year. Inspections on boiler and furnace systems should include ductwork, pipes, dampers, valves, the chimney, registers, radiators, pumps, blowers, fuel lines, the gas meter, oil tank and every part of the actual furnace and boiler. Meanwhile, heat pump and air conditioning unit inspections should also include inspections of the fan, compressor, indoor coils, outdoor coils, line kits and refrigerant lines.

What are the advantages of a programmable thermostat?
Since they are electronic, programmable thermostats are more accurate and efficient than thermostats that contain mercury. With programmable thermostats you can control the temperature in your home at different times of day without ever touching your thermostat. Because everything is automatic, you will never forget to change the setting on your own.
What type of filter should I use? And how often should I replace it?
Standard filters work to keep your system and its ductwork clean, but they don’t really improve indoor air quality. To do that you need a media filter. The media filter rests between the main return duct and the blower cabinet and will improve dust and particle removal by seven times that of a standard filter. However, upgrading to a pleated media filter will remove everything from insecticide dust to airborne viruses from the filtered air. Always choose a filter that matches your blower’s capacity. For optimum efficiency and filtration,Ambrose Air, Inc. recommends that you replace your disposable filters at least once a month. If you have washable filters, they should be cleaned once a month.
