Improper suction line sizing means extra work for the compressor and a shorter lifespan overall. For instance, if these lines aren't the proper size, your compressor will suffer. Other problems at the suction lines can cause compressor failure as well. If blockages are severe, the compressor may even overheat and burn out. When this happens, the compressor has to work overtime to keep refrigerant moving. Air conditioner compressor crack#These components may crack or develop tiny holes as the result of ongoing wear or excess strain. The Refrigerant Suction Lines Are Damaged or Blocked The refrigerant suction lines in your air conditioner can get blocked and clogged and cause compressor damage. During tune-ups, lubricant levels are always checked and replenished as needed.Ĥ. Lubricant loss can also happen as the result of loose pipe connections or a leaky condenser or evaporator. Lubricant is naturally lost over time, and oils that are subject to high heat gradually lose their efficiency. If you aren't having your air conditioner inspected and tuned up annually, you're bound to run into troubles in this area. Low levels of oil increase the amount of friction that your compressor's parts are subjected to. Without it, wear is expedited and systems overheat. Insufficient Lubrication Equipment with moving parts always needs lubrication. If you believe that this is what happened with your compressor, you may be able to hold the company that performed your last service accountable. When refrigerant levels are too high, pressure builds within the system and the compressor breaks down. Refrigerant refills should always be done to manufacturer specifications. In fact, too much refrigerant can actually wreck your AC compressor. In this case, it's definitely possible to get too much of a good thing. But how do air conditioners get too much refrigerant? If you've ever had a refrigerant leak before and called an HVAC technician in to fix it, it may be that more refrigerant than necessary was added during this service. Worn parts and loose connections allow this vital fluid to seep out. There’s Too Much Refrigerant in Your Air Conditioner Having insufficient refrigerant in your air conditioner is explainable. Having your air conditioner inspected and tuned up before the hot season hits allow HVAC technicians to spot and correct these and other issues before they cause your compressor to overheat.Ģ. Dirty, dusty coils, insufficient insulation, and refrigerant leaks that are left unchecked can all cause overheating. If your compressor is installed in a location that gets lots of natural light but provides limited ventilation, it's unlikely to last long without a continuous strategy for mitigating solar heat.Ĭompressors can also overheat as a result of insufficient maintenance. Overheating Overheating can cause an AC compressor to fail outright, and there are many reasons why a compressor might overheat. What follows here is a discussion of nine AC compressor problems that often rear their heads. Air conditioner compressor professional#Knowing the issues that compressors are prone to developing can be key for knowing when to seek professional help. Thus, if the AC compressor fails, your air conditioner may continue to run, but your living environment will remain hot and stuffy. When refrigerant returns to the compressor as a gas, this component compresses or pressurizes it to keep it moving. It's what drives the heat exchange process. This is the costly, outdoor component of the cooling system in your Hooksett, New Hampshire home, and without it, you wouldn't have cooled air. If refrigerant is the lifeblood of your air conditioner, the compressor is its heart.
