Do not bend the "fins" on the outside of the condenser. Make certain to wash the coils in an "up/down" fashion.
Do not attempt any repair work unless you are a licensed heating and air conditioning technician. Most states require a licensed heating and air conditioning contractor to perform any repair work.
Do not attempt to add or remove refrigerant from your system unless you are licensed by the EPA. Fines and penalties await those who tamper with or release refrigerant in an unsafe or unapproved fashion.
Do not attempt to diagnose any electrical problem unless you have been properly trained and/or are licensed.
Do not immediately assume that if your air conditioner is not working that the thermostat is at fault. Tampering with the thermostat or is related wiring can cause more problems than you initially started with. If nothing is happening with the thermostat set, immediately call for service.
When in doubt, stop. Immediately call a licensed heating and air conditioning contractor: 239-596-5855.
