During the summer months one of the most common problems with air conditioning systems is getting low on freon. This is a problem that normally ends with the air conditioning contractor putting a few pounds of freon in and calling it quits. This is not the correct way to solve the solution, and never a repair that will last forever. By going through the next steps I have provided in this article you can guarantee your air conditioner will work next year.
The way an air conditioning system works is by using a refrigerant freon and letting it change its state to take the heat out of the air. This refrigerant is in a sealed system which should never have to be replaced or recharged. When a proper installation of an air conditioner is performed the contractor should put a vacuum on the system to check for any leaks. If there is a leak in the system it needs to be found and repaired. This is where the problem normally comes into effect. during the installation process either someone had a bad braze weld or didn’t put a vacuum pump on and there is a leak.
This leak could go undetected for a few years and by the time the customer notices it there is no more warranty on the product or installation. When another contractor comes in to look for the problem they just fill it up and take the easy money. This charge to fill with freon can range from $350-$675 and after doing that a few times the customer can spend more than the system is worth. Not to mention the damage the low freon will do to your compressor and cause future problems.
The proper thing to do in the case of a loss of freon is very easy, and after the fix you can be sure that you will never lose freon again.
What you need to see the contract rod is put the system into a positive pressure using nitrogen. By putting that much pressure in the system you will be able to hear the nitrogen leak and repair the problem. If the problem is in the outside or inside coils you need to have them replaced. Hopefully the leak was in one of the original welds and can just be touched up. After the repair there needs to be a vacuum put on the system. By bringing the system to a negative pressure you remove all of the noncondensables and any moisture in the system. Let this vacuum sit for an hour and see if there is any loss. If not recharge to factory standards and you air conditioning system will work well for a long time.
