I have a commercial 5 ton unit that is not blowing cold air.

Air Conditioner pipes froze, I thawed them, and now air conditioner won't blow hard. Blows cool, but no pressure.

Repair
A new air conditioner can expect to give you between 10 to 20 years of service, but problems that require AC repairs will crop up casually. Most air conditioning repair problems involve minor repairs that can be done at home. For instance, you can do simple central air conditioning troubleshooting at home. If your central air conditioner runs, but fails to cool effectively, the unit may just need cleaning. Turn off the main power supply to close all power to the unit. Remove the protective cover from the condenser fins, and clean dust and dirt, vacuuming with a small brush attachment. Remove the topmost grille, and hose the fins inside the unit. Place all the parts back together, and switch the air conditioner on. If you still don't see any improvement, call an AC repair technician to perform air conditioner troubleshooting.
Improper installation of your air conditioner is also a leading cause of air conditioner problems. For instance, if your AC technician did not charge the correct amount of refrigerant during installation, the unit can quickly develop leaks. Improper operating procedures can also lead to air conditioner repair problems. For instance, switching air conditioners on and off frequently can cause the compressor and fan controls to wear out. if your air conditioner does not switch on immediately, check to see if the thermostat has been set to "cool". It should also be set to below the room temperature. Check if the breaker has tripped or if a fuse has blown. If you notice grinding noises in your blower, call your AC repair technician. Usually, it's a problem with improper belt alignment. If you notice pools of water accumulating next to the unit, check to see if there is a leak in one of the tubes. If not, it could be a problem with the pump.
