Just about 90% of calls made regarding central-air service are pertaining to leaks. Even though these types of leaks are usually small, they can create a great deal of damage if left unchecked, particularly if it is dripping downward due to the air handler being installed above the ceiling. The majority of leaks can be fixed without having to call in a professional technician; however, many homeowners do not realize this.
Hazardous to Environment
The refrigeration or air conditioning system’s cooling medium is known as the refrigerant. In many refrigeration systems and residential air conditioners, it is refrigerant or R-22 which is a CFC or chlorofluorocarbon. The Environmental Protection Agency controls refrigerant since it is hazardous to the Earth’s Ozone layer if released into the environment.
Hazardous to your AC System
It is essential that the refrigerant level or coolant of the AC system is check regularly. Electrical costs can increase up to 20% more for the homeowner should there be a 10% loss of coolant or refrigerant and this can result in unnecessary wear and tear to your system.
Compressor failure can happen during low levels of refrigerant, reducing air conditioning efficiency, freezing up the evaporator coil, and a whole list of other issues. Not to mention, refrigerant leaks only continue to get bigger and more severe over time, therefore, repairing the leak as soon as possible will save lots of money. There are laws that have been established where professional contractors are not permitted to add refrigerant to a system that is leaking if it is within 30 percent of the capacity of the unit. Instead, they are by law, required to repair to leak. If they should violate this law, they can lose their license.
Energy Wastage & Benefits of Fixing Leaks
A 20% Waste Factor
Reports from Federal Energy Star state, the standard home AC unit can lose up to 20% efficiency due to leaks. A complete list of benefits that can be gained by repairing the problem are as follows:
* Reduced energy bills
* Reduced repair costs
* Less repairs needed
* Better system efficiency
* Better air flow distribution resulting in more comfort
* Air is cleaner indoors due to a reduction in allergen and irritant intake
* Environment friendly
* Better peace of mind owning a HVAC system that runs more safely and efficiently.
Fixing the Leak
A professional technician will need to come in and repair large refrigerant leaks. In some cases, they might have to solder holes or cracks in the line or replace condenser coils or evaporator. Should your unit lose all its refrigerant due to a large leak, the technician will have to evacuate it and eliminate any condensing gases or moisture from the unit. A vacuum pump is used for this job and will suck all contaminants out of system. If not done, your unit will not operate efficiently even if it is recharged. With small leaks, the homeowner can usually do the job with a refrigerant leak repair kit which will save money.
