Life in Texas without air conditioning would be unbearable. I recommend yearly lubricating your condenser fan motor's sleeve bearings with an ISO 32 turbine oil. Top lubricants would be Amsoil's RCH Series, Synthetic RC Series Rust & Oxidation/Antiwear Gear, Bearing, and Hydraulic Oil, or Exxon Mobil's SHC624 Synthetic Motor Lubricant. Unocal 76 also makes a fine ISO 32 mineral turbine oil, available from ACE Hardware, in a 4 oz. zoom spout oiler. 15 drops of oil, per bearing, is all you need. Make sure to turn off the 220v. breaker to the air conditioner and the 110v. breaker to the furnace, before ever servicing the unit.
If you regularly hose off your condenser coils from the inside, lubricate the condenser fan motor, and replace the contactor every 6 to 8 years, you will greatly extend the life of your unit, save yourself a lot of money, and not have it die on the hottest day of the year.
