Air Conditioner Repair: What You Need to Know

There are some aspects of air conditioning systems that you should know about before attempting to conduct air conditioner repairs in your home or workplace. If their air conditioning system breaks down or a flaw occurs, without thoroughly knowing the principles involved, many individuals attempt to repair it themselves. However, once you understand the concepts, it is possible for you to conduct a simple air conditioner operation, while HVAC repair (heating, ventilation and air conditioning) is best left to the experts.Learn more about us at MaxCare Heating & Cooling – London heating companies

Using basic mechanics, the standard home or office air conditioner operates and consists of two different units: the condenser and the evaporator. Freon gas is placed under pressure in the condenser and then passed through a heat exchanger to extract heat from the gas and convert it to a liquid. It is then passed into the evaporator through an expansion valve; the liquid Freon expands and evaporates to a steam, the latent heat required from the atmosphere for this, which is then cooled (the cooled air then being blown into the room). The gas that is heated by the higher temperature of the room air returns to the condenser where the heat is extracted and the cycle begins.

Both the evaporator and the condenser are sealed units and you will not repair them yourself with any air conditioner: you would need to contact a qualified professional. Keeping it clean and all the mesh guards and so on free of debris is what you can do. Simple air conditioner operation can be carried out on your own, but not HVAC repair. Here are some simple repair, troubleshooting and service tips for air conditioners.

  1. Fails to operate the machine.

Test the circuit breakers or the fuses. If they’re all right, then make sure the thermostat isn’t set too tight. Try to lower it by 5 degrees, and you will need a skilled HVAC repair engineer if that fails.

  1. No Refrigeration.

Check the thermostat once more, and attempt to lower it. If that doesn’t work, check the air intake of the condenser. It could be blocked, particularly if there are lots of leaves flying around in the fall. Check that the fan’s fins are straight, and then straighten them if not. Then call a trained engineer if nothing works.

  1. Erratic refrigeration

Everything you can really do with this and all other faults is to clean the condenser as best as you can, and if that fails, call an engineer. It is not unusual for units to be blocked by one or another type of vegetation. The condenser will probably sit on a concrete pad: make sure that it is level, because sometimes the concrete will break down and put the condenser and the motor out of the level. That can influence the activity of it.

Sealed units are the condenser and evaporator, which is why it is so difficult for amateurs to repair their own air conditioner. The most common problem which you can repair yourself is a blocked or dirty evaporator. If you have a daily air conditioner service carried out by a specialist, you should not encounter these issues, even when vegetation and other debris may be blown into the device in severe weather conditions.
