Trouble shooting
Do not attempt repairs by yourself. Refrigeration Technicians are qualified to perform repairs and only technicians with an Ozone Depletion Ticket can charge and recover Freon. Leave trouble shooting to an experienced contractor.
If you did anything on your system, it is best to be honest and tell the technician so he can accurately diagnose your problem. You could save yourself hours and unnecessary tests. Remember trouble shooting air conditioners are better left to an expert in air conditioning.
There are of course, some common causes to problems, you could yourself ensure to avoid.
Filters - Clean your filters. A dirty filter restricts air flow and can cause major problems.
Batteries - Thermostats with incorrect readings will not send the right signal to your system.
Vents - A simple fact like a restricted vent causes obstruction and affects the whole air flow system.
Power - Yes, sometimes a tripped switch goes unnoticed. Reset the power switch after a few minutes.
Since the Montreal protocol all refrigerants are to be recovered. Recovery of refrigeration including R22 R 501 and any other ozone depleting substances must be recovered. The products in these refrigerants are considered to contain harmful contaminants to the atmosphere. You may find that all scientists do not believe in this theory. As we do not have the resources n this page to substantiate this we suggest you do some of your own research. Type in Freon scams ,that is the best I can tell you at this point. If I have the chance I will get further information . As it is now we recover all refrigerants for the Montreal Protocol.
