Only a qualified service technician can tell you if the unit needs to be recharged, by testing in the input and output pressure. It would be a good idea to have it serviced professionally, since it's never been serviced. It could be money, well spent. Or it could be a Long Hot Summer without the AC.

Tip

Save cost with some precautions


Precautions to be taken in air conditioners and to save cost.

These are some useful precautions to be taken in air conditioners (A/C).Improper refrigerant charge can damage your compressor, which is the heart of your air conditioning system; this is an expensive air conditioner repair. Systems improperly charged will cause increased electric bills because this will reduce the efficiency of your air conditioning system. The proper refrigerant charge will provide longer equipment life, lower your utility bills and reduce the need for air conditioning service.
A dirty condenser coil (outside unit) will reduce your air conditioning systems ability to remove and reject heat from your home. This will cause your system to run longer and increase your electric bills. The benefit of a clean condenser coil is proper heat rejection, reduced run time and lower energy bills. A dirty air conditioning condenser can lead to system failure and the need for you air conditioner to be repaired, dirt and house dust that escapes through your air conditioning filter can cling to the cold moist coil. This will restrict the air flow through the coil reducing your air conditioning system of performance and capacity. Maintaining the evaporator coil will ensure that proper air flow is delivered to all areas of your home, increase comfort levels, provide a cleaner healthier indoor environment. Inspecting and changing your air filter on a monthly basis will help prevent air conditioner repairs.
As your air conditioning system removes heat from your home, humidity is extracted from the air. The condensation created by warmer air passing over a cold coil must be drained from your system. This is done through a condensate drain line. The drain must be checked and cleared of algae build up or foreign particles clogging the drain, which could cause water damage to the ceiling or floors of your home. By keeping your air conditioner drain line clear you will reduce the need for air conditioning service and overflow problems which can result in water damage. Proper draining will also aid in maintaining indoor humidity levels.
Cause of air flow
Dirty blower wheels can affect the air flow to your home; limit your air conditioning system's capacity and your comfort. It can also spread dust particles which irritate sinus and allergies. A clean blower wheel and fan motor will provide maximum air flow, improved comfort levels and proper cooling. Most of air conditioner repairs are caused by dirt and the lack of maintenance.
Cause of electrical panel
Your thermostat should be properly calibrated. This will ensure accurate temperature control and operating cycle. This will save you on operating cost and assure your comfort level. Moving parts in need of lubrication can cause increased electrical consumption and air conditioner repairs. This is due to additional power required to overcome the resistance in motors and drive shafts that are not lubricated. Proper system lubrication will offer smooth motor and shaft operation, extended part life and less air conditioner repairs. The electrical components on your air conditioning system should be inspected regularly for signs of wear. Faulty electrical components can lead to very expensive air conditioning repairs. A thorough inspection will reduce the need for air conditioner service if the faulty or worn parts are replaced when found.
Carrying this tips help reduce the amount of air conditioner repairs you will encounter over your air conditioning systems lifespan. If you are in need of air conditioner service make sure the company you choose is licensed and insured to do the required repair work (warranty) .

A few basic principles for air conditioner troubleshooting. For both central home air conditioner or window air conditioner, the first thing to check is whether the unit is getting proper power. If the unit uses 220 volt power be sure that the proper voltage is getting to the unit. Same for 110 volt units. A voltage meter can be used to assure that the voltage is correct.

For window air conditioning units the voltage can also be checked before and after the thermostat. If voltage is being supplied to the thermostat but not from it then the thermostat probably needs replaced. This is a fairly common problem. Another place to check is the fan motor voltage. The fan on window air conditioners runs both the indoor blower and the condenser fan. If that motor fails than the compressor may run for a short time, but will overheat and shut off. Continued operation like this will result in compressor failure. This motor can be economically replaced for larger window air conditioners, but for smaller ones the cost of replacement will be more than a new unit.

Central air conditioners for the home are more complex and there are more things that can go wrong. As with the window air conditioner the thermostat can also be a problem. The central air conditioner thermostat will only have 24 volts going to it. So don't look for high voltage there. Some units the voltage will be coming from the outdoor unit and others the voltage will be supplied by the indoor air handler or furnace. Most home central air conditioning will be supplied by the indoor air handler or the furnace. If the air conditioner is for cooling only the unit will usually have only two wires going to the condenser unit. Make sure that you have 24 volts across those wires.

The next thing to check will be the indoor blower. If your thermostat is calling for cooling then the indoor blower should be running. If there is no air moving across the indoor cooling coil then you will soon have a big block of ice formed on the coil. This can happen for a few reasons. The indoor blower is not working, the air flow is restricted and not allowing air to move across the coil. A clogged air filter would also do this. Or the outdoor condenser unit has lost the charge of refrigerant.

Finally and worst of all is when you have a complete compressor failure. Often when this happens the compressor will "lock up" or not be able to turn when power is supplied to it. Overheating or lack of lubrication are usually the main causes of compressor failure. Overheating can be caused by the outdoor coil around the compressor getting clogged with dirt, leaves, or grass. Loss of the refrigerant charge will also cause the compressor to overheat. It is the cool return gas coming back to the compressor that helps to keep it from overheating.

As you can see there are many things that can go wrong with an air conditioner and I have not come close to exhausting the possibilities here. I have just touched on the most common problems in a very basic way.
There are some basic trouble shooting things that can be done very easily. Most problems are above out of the range of comfort for many homeowners and professional help should be consulted before any attempt is made at repairs. Remember also, that the release of refrigerant gases into the atmosphere is a federal offense in the
US. Proper care must always be taken to minimize the release of any gases. A license is also required to handle refrigerants. Make sure that the professional you call has the proper certifications to handle refrigerants properly.
