Air conditioning replacement service

Air conditioner replacement service is offered by companies who have found that one or more of your AC components need to be replaced. Most air conditioners are made up of the following major components:

  • Compressor
  • Condenser
  • Receiver (drier)
  • Expansion valve (orifice tube)
  • Evaporator
  • The major components are expensive to replace while the other parts such as the pipes, nuts, o-rings and valves are more pocket friendly. The service companies stock the parts and they will be easy to replace. Unfortunately if the system is too damaged you will have to replace the entire AC unit. The refrigerant is the liquid used to transport heat from one part to the other.

    This is how all these parts function when you turn the AC on and the compressor compresses the system’s refrigerant raising its temperature as it absorbs heat. It then loses heat when it flows through the condenser where it is cooled using the condenser fans. It then passes through the receiver or dryer where contaminants and moisture are removed using the desiccant and the filters, and then on to the expansion valve where the refrigerant is slowed down further, causing it to lose pressure and temperature before it gets to the evaporator. The evaporator cools down further to lower the refrigerants temperature. The ventilation system blows air over the cold evaporator and pushes this cool air into the passenger compartment.

    The first thing to do when you notice a problem with the functioning of your AC is to call your maintenance person who will have a look at the AC and give a diagnosis. This initial check is offered by some service companies for free and some charge for it. So you may have to find the best service provider who you are willing to work with according to your budget. It is important to have the brochure from the company in order to get their range of charges and to get a great and affordable service provider.

    One of the problems that can lead to the parts to be replaced is caused by refrigerant leaks. Refrigerant leaks unlike oil spills which leave black stains are not so easy to see and this is because when refrigerant is exposed it evaporates. When servicing your AC the technician will use a special dye add it to the refrigerant and then it will fluorescence when exposed to a backlight. This way the technician can detect the leak and fix it. Then he will add more refrigerant to the air conditioner. Leaks are dangerous because when they come to contact with moisture they become corrosive and start to eat away at the compressor which is very expensive to replace.

    When you have to replace entire units there are a variety of installations available from window air conditioner to central air conditioners. You can get a contractor to help you pick the most suitable model for you that will not use too much energy.
