In this blog post, we want to start talking about the differences and scope between a preventive and corrective maintenance service.

Although it is clear, the preventive maintenance service for air conditioning equipment is one that is provided with a certain periodicity -it will depend on different factors such as its use, location and the equipment model, in order to preserve the unit working at optimal conditions for as long as possible.

Preventive maintenance is not just opening the evaporator lid, removing the filters and removing the dust or lint that they collect over time, it goes much further. A service performed by professionals should carry out at least the following actions:

• Evaporator motor cleaning.
• Cleaning evaporator fans.
• Cleaning and emptying the drain pan.
• Checking and cleaning the condenser cap.
• Checking and cleaning the control card or motherboard.
• Pressure cleaning of filters and protective caps on the evaporator.
• Check with a pressure gauge the amount of refrigerant gas in the equipment.
• Review and prevention of gas leakage in ducts between condenser and evaporator.

Carrying out these types of actions routinely, will provide some of the following benefits to users:

• Energy saving.
• Increase in the useful life of the equipment.
• Hygiene and health of the environment.
• Reduction of unforeseen expenses.

Preventive maintenance prices are relatively affordable, there are many suppliers who can carry this type of services but it is highly recommended to ask for credentials and recommendations before letting a rookie learn and gain experience with your unit. 

If for some reason there has not been an opportunity to carry out preventive maintenance and a corrective maintenance is required, it is recommended that the technician be notified in advance about the faults that the equipment may show at first glance -cooling problems, gas leakage coolant, leaking or dripping water, excessive heating, etc., in this way they can go prepared and the service will be faster.

Now, a corrective service carries the same procedure as the preventive one, with the difference that in this the cost will increase due to the fact that equipment components that may be damaged due to use or lack of maintenance will have to be changed; Among the main problems seen, we can find the following:

• Capacitor change.
• Refrigerant gas refill.
• Change of drain hose.
• Damaged electrical connections.
• Some parts broke due to improper handling.

The price of a corrective service is practically impossible to anticipate since the technician’s visit will be to review the equipment and determine what problem the unit presents and what is the recommendation to give it an immediate solution.

If the equipment is of recent acquisition, in most cases the problems can be solved by changing parts or doing this type of maintenance services, but there are some others where the solution can be so expensive that it will be worth doing the analysis between repairing it. or buy a new unit.
