There are preventative causes of AC Compressor Failure, so you were told you have a bad compressor.
If your air conditioner or heat pump system fails to cool your home or business, you should call an air conditioning and heating contractor to fix the problem.The technician arrives to fix the air conditioner system.
30 minutes later, the technician tells you that your compressor overheated and needs to be replaced or it needs a new system.
A serious matter is the burn out of a compressor.Replacing the system requires a judgement call.The cost of a burned-out compressor replacement is what determines it.You might have to pay for labor if the failed compressor is still under warranty.It is likely that you will have to pay for labor to replace the compressor.The current age of the air conditioning and heating equipment and whether you have the money in your budget to replace the system are other factors.
You need to know what happened to cause the compressor to burn out.The primary cause of air conditioning and heating compressor burn up is neglect.There are a number of reasons an air conditioning compressor can burn out.The things that are in your control need to be addressed on a regular basis.
Excess heat inside the compressor can be caused by some of the things on this list.Oil in the system and excess heat inside a compressor are not good for each other.With excess heat that is outside of design temperatures, metal components will fail or not work as designed, causing the oil to breakdown, and that leads to more heat.If the situation gets out of hand, you have to either replace the whole system or the compressor.
The air conditioning or heat pump can fail due to poor maintenance.Poor maintenance on the compressor causes it to burn out.The hermetic compressor is maintenance-free, so you need to look at the condenser instead of the compressor.Dust, dirt, and debris can accumulate in the air conditioning and heat pump condenser coils over time.
Under extreme operating conditions, the air conditioner or heat pump compressor has to work harder to compress and pump the refrigerant.
The compressor runs hotter than normal when it works harder.Over time, the compressor will fail and burn out if it exceeds it's normal rated operating temperature.
The built-in protections against compressor overheating are prone to failure under extreme conditions or may allow the compressor to run at just below the temperature protection level, but over time this higher than normal temperature will cause the Compressor to burn out.
A compressor can burn out if there is a restriction.A malfunctioning metering device or damage to the line set can cause compressor burnout.The flow of refrigerant can be restricted by damaged or crimped copper lines between the condenser and the evaporator coil.
The air conditioner or heat pump compressor will work harder if the pressure in the system is not balanced.Under extreme operating conditions, higher compressor operating temperatures andamp draws can lead to burnout.
When someone steps on or twists one of the copper lines running from the air conditioner to the heat pump, the line can become damaged.The cooling capacity of the air conditioner or heat pump system may or may not be affected by the damage, but it needs to be fixed as soon as possible.
When the installation crews inadvertently crimped the lines, the problem can remain hidden until the air conditioner or heat pump system has a compressor burn out.A good air conditioning or heat pump technician can help resolve the issue and prevent a compressor burnout before it happens.
Delve deeper and learn more about the pros and cons of heating, ventilating, and air conditioning (opens in a new window).
Air conditioning or heat pump compressor burn out can be caused by restricted or malfunctioning metering device.It can be difficult to diagnose when the problem is intermittent.Fixed orifice metering devices and thermostatic expansion valve devices are the most common.
If the system has a lot of trash or ice it can lead to compressor burn out.It can happen with a TXV metering device.The fixed orifice metering device can malfunction and cause a compressor burn out, but the TXV is more complex.The system can experience restrictions because the TXV has moving parts.
Two weeks later, the technician is looking at another compressor that has been burned out.When the new compressor was installed, the intermittent problem was not diagnosed.Everyone is scratching their heads, the air conditioning or heat pump technician looks bad, and the customer is upset.It's best to find the intermittent metering device problem and replace the burned out compressor.
The air conditioner or heat pump compressor can burn out if the system is humid.Poor installation can cause a compressor to burn out if there is too much humid air in the system.The oil in the system creates an acidic sludge that eats away at the windings on the compressor motor.
Proper installation practices must be used by the installation technician.When opening the air conditioner or heat pump system, the service technician should use the proper methods and procedures.All non-condensable gases in the air-conditioning or heat pump system can be eliminated with a triple-evacuation with nitrogen purge.
The proper filter driers will help prevent compressor burn-up.Any time the air conditioner or heat system is opened, the filter drier should be replaced.
Air conditioner or heat compressor burn out can be caused by oil loss from refrigerant leaks.When the cost of filling the air conditioner or heat pump system is cheaper, many people don't want to pay to find a leak.Oil from the system leaks through the same hole where the refrigerant is leaking.
Good lubrication and cooling of the compressor can be achieved with the proper oil level.The oil in the air conditioner or heat pump compressor contributes to keeping the compressor cool by reducing the amount of air in it.If you want the best advice, you should have the technician fix the leak.
The long term alternative will cost more than just filling the air conditioner or heat pump system with refrigerant.The newer R-410A systems operate at higher pressures than the older R-22 systems.
Air conditioner or heat pump compressor burn out can be caused by compressor short cycling.That happens when the unit is turned on and off quickly without giving it time to recover, equalize, and cool down.An air conditioner or heat pump compressor pulls a high draw on startup.
It takes less than a second for the compressor to start.If the unit quits within the last 3 minutes, the head pressure is still high and equalizing.This increased heat level can cause a compressor to burn out, and starting and stopping the compressor continuously under these conditions will create a lot of heat.
Under these circumstances, an air conditioner or heat pump unit with proper controls will prevent compressor burn up.Digital heating and cooling thermostats can protect against short cycling.The built-in time delay on the thermostat prevents the user from turning the air conditioner or heat on and off too quickly.
The contaminated refrigerant will cause problems if the system was recovered and the recovery tank contained it.The acid will cause compressor failure eventually.It is best to use virgin refrigerant on the refill if the technician can't do a pump-down method into the condenser.
When the evaporator isn't absorbing enough heat, liquid refrigerant makes its way back to the compressor.The liquid will cause damage to the compressor.
Defective compressor can cause an air conditioner or heat pump compressor to burn out.It does happen, but it is not very common.If this happens to you, the air conditioner or heat pump compressor is still under warranty.The technician needs to look at the other issues before determining if it was a faulty compressor.
There are other issues to look at in the air conditioner or heat pump compressor system.The rating by the manufacturer of the compressor should be taken into account.Anything out of this range can cause compressor problems.
Lightening strikes can cause damage to the air conditioner or heat pump compressor.Hopefully, your insurance will cover the cost of replacing the air conditioner or heat pump.The system may be damaged beyond repair if a large amount of voltage and current passes through an air conditioner compressor.
One of the most common problems for compressor failures is compressor lock up.A heat pump compressor is a mechanical device.The mechanical parts are driven by an electric motor.The compressor is mechanically locked up if the mechanical parts lock up or seize up and the electric motor in the compressor does not have the power to overcome it.
25 percent of compressor lockups can't be unlocked with a good air conditioning and heat pump technician techniques.It is necessary to replace the air conditioner or heat pump compressor.Most problems that can cause a compressor to burn out, burn up, or mechanical lockup can be prevented by having a regular maintenance schedule for the air conditioner or heat pump system.
Installation technical techniques are important for a split system or when the refrigeration portion of the air conditioner or heat pump is opened for any reason.A compressor burn-out can be avoided by doing the job right.It is important for any technician to use the triple evacuate method before opening the system or installing a new one.R-410A is used mostly in residential heating and cooling.
There is a video about preventive maintenance on the air conditioning compressor.The burned-out compressors are caused by dirty condenser coils.
Is it possible that the heat pump could have frozen due to the extreme cold of -5 below and 32 for 7 days?What steps would have to be taken to determine what caused the compressor to fail?
The air compressor on the heat pump went bad a few months ago and I had a new one installed with an A coil.I didn't have enough money to buy a new furnace when I wanted to sell it.I had a different company come out and tell me that there was a 5 1/2′′ gap behind the A coil, which could be causing the freeze ups, if I put the thermostat below 73 degrees.
I don't think it made theCapacitor go bad.When I first read your story, I thought it was an issue with the air flow, and a 5.5-inch gap would cause it.
The person who installed the system didn't know what they were doing.The charge will be off if there isn't proper air flow.The second guy should take care of everything for you.Capacitors can go bad.
The AC was scheduled for maintenance on May 1.It is 12 years old.The tech said everything is working correctly after inspecting all the AC parts.No issues or concerns.I turned on the AC for the first time on July 6 and it didn't cool the inside.After pulling out the connection, we noticed one side had melted.The compressor was grounded.How can a compressor become useless over 2 months when the original technician said it was working correctly?There is no answer from the AC company.
It could have been a mechanical/electrical issue or a lightning strike.
We had a technician check our AC and found that one compressor is dead short.The cable was disabled so that the AC could run on the bigger compressor.We had another technician check the compressors after 3 weeks and they were broken.There is another with open wiring.Is it possible that having one compressor run causes it to break?
I would get a second opinion from another company.It sounds a little odd to me.It sounds like you have one of the older systems that has staging with two compressors and from my experience the odds are way out there that both failed in the frame you are describing.Try another company.Sometimes dishonest technicians are created by companies that pay their technicians a commission for selling new equipment.It is possible that those techs are being dishonest.It is best to replace a compressor if it fails in an older system.It's important to get a second opinion before doing a big job.If the new company finds a simple problem and gets the old system running again, it can save you a lot of money.
Yes, on replacing the compressor.The compressor motor has a dead short.There is no repair for this because the compressor is sealed and the windings are touching each other.
The heat pump in the 12 year old Coleman had failed.He was out for 3 days because the new one also failed.They have to add coolant every time they have a leak, and I am constantly having issues with leaks (Condenser coil fitting, plugged filter from discharge line, reversing valve at center port).There is a leak that cannot be fixed and the whole unit needs to be replaced.I've paid over $1300.In service calls.I feel like I have been paying for incompetence.Coleman should have been contacted about this unit.
Many of the equipment they sell are good for 13 to 16 years when properly installed and maintained, according to others in the industry.Within that time frame the industry has made improvements and the efficiency levels have jumped not only through mandates but also innovation from the ever changing and improving technology.If you have had several problems with the equipment, it makes sense to replace it after that time.A good manufacturer will offer a good warranty.
I know Daikin and Maytag have limited parts warranties.Many of the warranties do not include the cost of labor, so you should always read the fine print.
If someone is going to give me a 12 year warranty on something that has many moving parts, I think they make quality products.Products that are reliable will not break down often.
Selecting the best contractor to install the system is the most important part of selecting any equipment.Poor installation has caused problems.Installation is an important factor in the proper operation of equipment.It makes a big difference in the efficiency of the unit.If you need help, you can use the provide links to find a goodHVAC contractor and read more about proper installation, reliability and energy efficiency.Our free guide can be used to help you.We have a lot of information here to help people make decisions.
Sorry, you have some problems.Coleman probably won't do anything at this point.If you contact them, they will likely tell you that they have no liability outside of the warranty.You can write a review of your experience with Coleman.It will let other people know about your system.You can look at our reviews to make a decision.I emphasize to homeowners buying new equipment to make sure they do their homework on the contractor.We have given you all the information you need to complete your homework.Good luck!
I had my heat pump serviced.The large amount of freon was not covered by the warranty.The technician told me that I need to replace all the freon because it could be bad.Is this possible in 3 weeks?When we noticed the issue, we started using the AC again.
Acid inside the refrigerant is what causes it to go bad.Poor installation practices and not properly evacuating the system are some of the reasons for the moist system.For more information, visit high performancehvac.com.It depends on the problem with the compressor.Was it a fire?The windings might have burned up.If that is the case, then the system should have been flushed before the new compressor was installed so that the residual oil wouldn't cause the compressor to burn out.Refrigerant does not go bad or burn up by itself, so not sure what happened in your case.The issue is caused by some other factors.
The outdoor unit will run for 1-2 seconds, then turn off, and then come back on again.I installed a hardstart kit, but it still won't say on.What could be causing this?
On the face of it, it doesn't look good for the compressor.I can't say 100% without looking at it.
It's difficult to diagnose without readings.It could be shutting down due to overamping caused by bad start devices.Low pressure or high pressure switches could be the cause.There are possibilities for low air flow inside or outside.
The compressor unit was short.The compressor unit that I have shorted blew-off.The system is well cared for.There are no air flow restrictions when the filters are cleaned.The unit is old.The compressor shorted because of poor maintenance, according to my warranty.Are they correct?The compressor could short out.
Take pictures of the unit if everything is as you say it is.It is possible that you had an annual performance maintenance from the company.Call the company and ask them to send you a letter saying they did maintenance on the system.I think a lack of maintenance is a possibility, but they are probably trying to wiggle out of paying for that compressor by taking a shot in the dark.Most of the systems are designed with overload protection to protect against too much heat inside the circuit.
My compressor and fan have been replaced by a warranty company in the last three weeks.The compressor stopped working after 15-20 min each time.The need to replace the metering device and compressor is now being said.They reviewed the pictures and the dog urine and decided to ground the compressor.Is there any truth behind this?What else could it be?The unit is old but clean.
It is impossible for dog urine to enter the system unless the dog knows how to inject the urine into the circuit.I have seen dogs pee on the coils.The wires on the outside of the compressor are not affected by dog urine.An educated guess is that the system had some sort of problem.Maybe when maintenance was done.The main cause of burnouts is acid.The oil in the system creates an acidic sludge.A dead short is caused by the acid eating away at the protective coating on the windings inside the compressor.
Replacing the system is something I would recommend.It is not worth it to spend a lot of money on a new compressor when you can get a more efficient system that will be trouble-free.It would be a good idea to start thinking about it.
Since the home warranty is on the hook here and they are doing everything they can to wiggle off of it, you want a competent company to do the work.To get rid of the acid in the system, the entire circuit needs to be flushed.It is a good idea to replace the metering device.The system needs to be evacuated after it is flushed.You can use our search feature to find out about triple evacuate.If they do the job right and use correct procedures, your air conditioner should be up and running again.
The coil in the attic of my ac had a leak.We let it run for a while before shutting it down.The compressor wont start after I replaced the coil and Capacitor.After it was charged, it ran for a few seconds.Any suggestions?
It's difficult to answer this question without knowing the history.Is it safe to put it back into service?Was virgin refrigerant used?There are many variables that can be used to answer the question.Both are mechanically and electrical.
I have a new cooling unit.It ran for 3 hours.Will this affect the life of the condenser?
If there was no refrigerant in the system, the low pressure switch would kill the compressor if it tripped on overload.It is difficult to say if the life was shortened because the compressor is sealed.Fix the leak, evacuate the system and then replenish it.
I have an ac unit that is burned for 3rd time, I hope to find the problem, could you comment on electrical failure?
Do you mean 3-phase motor when you say triphase?The rotation of the compressor does not make a difference unless it is specified by the manufacturer.Unless the compressor manufacture has specified the rotation it does not make a difference.Something is wrong if you are replacing the compressor for the third time.If it is an electrical burn out, the entire system needs to be flushed to remove the old oil from the system, as the acid in the oil will cause it to burn.There are flush kits at the supply house.If it is a mechanical problem, you may have an oil issue.Either getting too hot or breaking down.The oil level is important.Most three phase compressors have an oil level indication on them so regular maintenance checks can be made to ensure there is plenty of oil to lubricate the compressor.
The higher the temperature, the greater the pressure in the system.If you stay with the range of specifications set by the manufacturer, you are okay.If the temp gets too high you will have serious issues.I'm assuming you're talking about a chiller since you mentioned water in the comment, the condenser does the job of removing heat.If the water temperature is 90 degrees, you will be removing more heat than if it is 105 degrees.You would have to run some efficiency curve experiments to find out what the effect is on energy use and cooling affect of equipment based on the temperature of the water.If you have the proper controls in the system, you can set up trend charts to get this information.
How would you explain blowing out a train unit?It blew out a compressor terminal and put a hole in it.It was locked up before it happened.
The compressor probably had serious mechanical issues which caused it to run very hot and that created an electrical problem.You won't know the root cause of the failure unless you open the compressor and do a forensic examination.Time consumer can be expensive.If the unit is less than 10 years old and has been well maintained, I would flush the system and replace the compressor.You can find an aluminum solder repair kit.If it is an R-22 unit that has not been well maintained, I would replace the entire unit, along with the line set.
I discovered the problem with my central AC system after it ran in the weather for over a day and a half.The compressor unit is still functioning, but it is making a lot more noise than it did before the blower motor failed.Is it possible that the compressor was damaged by running without the blower motor?
It depends on the type of compressor you have.A scroll compressor can take a lot of liquid.The compressor may have been damaged if you didn't have enough air across the coil.A good technician can perform a diagnostic check on you.Some type of mechanical damage can occur when liquid makes its way into a compressor.
