Several AC system compressors have run for over 30 years without failures. This runs specifically true with home refrigerators and freezers. I have known of domestic freezers lasting 40 years! The difference within a compressor in a refrigerator and a home air conditioning system is pretty important to understand. The refrigerator was made in a factory under careful quality control measures and supervision. The home AC system how ever is installed by a AC service technician and service company. One of the major problems in your house air conditioning industry is not enough qualified AC service technicians and AC service companies who want to perform quality work and get a high level associated with skill and knowledge. The pride to be a “Master Craftsman” has nearly vanished from the AIR CONDITIONING industry. Much of the this problem lies with AC assistance companys who push their technicians severely to perform in volume not in quality. I see this all the time as I have audited new home AC installations and AC systems that have been repaired.
AC system compressors fail for three basic reasons. Two of these reasons are preventable then one is not.
1) Electrical Problems due to problems from the power provider and lighting thunder storms. These problems cannot be eliminated completely regardless of the anyone tells you. Lighting produces very higher electrical surges and energy levels that can destroy not only AC system components nevertheless any electrical consuming device in your house. At my house I switch off all electrical power at the time of very severe lighting storms by turning off the power at the main breaker inside electrical panel. Sounds really crazy! I have not experienced an inability from any electrical thunder storms while my neighbor next to me had her Ac unit compressor and disconnect destroyed within a very bad storm there were.
2) Incorrect Installation and Short Cuts- It’s where service companies and service technicians create many issues with an AC systems function and useful life. Many service companies today continue to misapply AC systems by not sizing the system correctly and typically where I have inspected your home that has experience multiple system failures I have found the AC system to remain oversized. This causes short cycling as well as the system operating many hours within a non-design condition. Another problem I see is mismatched system components that but not only causes the system to operate poorly but has adverse effect on energy as well. Just about the most common and serious items could be the process of start-up after the system has been put in. For an AC system to own at its full potential and efficiency the system ought to be evacuated and de-hydrated for many hours. I recommend that a process be evacuated for at the least 8 hours with ambient temperatures in and above the 70 degree range to aid with moisture removal in the system. Any mositure left is a AC system will created numerous problems after a while. Moisture causes acid and sludge in the refrigerant system that may well stop up metering devices and attack the insulation of the motor windings. Any degradation with the insulation of the motor windings can result in a motor failure just by shorting the motor windings together or to ground. dallas real estate The Seller And the Inspector In Home Inspection
