Ac unit repair

An air conditioner is a system is used to cool the temperature within an enclosed area. It may sometimes break down and if it does you should call a technician to look at it. Most air conditioners are made up of the following major components:

  • Compressor
  • Condenser
  • Receiver dryer or Accumulator
  • Orifice tube or Expansion valve
  • Evaporator
  • It also consists of pipes and the refrigerant. It works in a manner similar to the refrigerant cycle. The compressor is the central part of your air conditioning system. It is responsible for pressurizing the refrigerant. The refrigerant then absorbs heat and because it has a low boiling temperature it changes into gas. The compressor is powered by a serpentine belt and it monitors change in temperature with the compressor clutch. If your AC has a problem it will start getting noisy, having leaks and an overall poor performance of your system will show the technician that it needs to be replaced.

    Signs of a worn compressor: Freon leaks, noisy unit and reduced performance and no operation are indications that a compressor may need to be replaced.

    The condenser is the component that turns hot refrigerant gases into liquid using electric fans. The condenser is mounted at the front of most vehicles in front of the radiator. Air passes through the condenser, turning the hot refrigerant gas into a condensed, cooler refrigerant liquid. An AC condenser is responsible for cooling the hot refrigerant gas after it leaves the compressor and can be found to effective on the outside of the home to release the heated air from inside the room for a room air conditioner unit.

    Signs of a damaged condenser:

  • Leakage
  • Clogged system, corroded or damaged fins or tubes due to refrigerant coming into contact with moisture and becoming corrosive
  • General poor performance of the air conditioner
  • The receiver or dryer is found on vehicles with a thermal expansion valve. It is traps contaminants and moisture from getting to the compressor and other major parts of the air conditioner and it also prevents the mixing of such contaminants with refrigerant. The receiver or dryer:

  • Separates gas from liquid. If liquid is not contained in the dryer, it can enter and destroy your compressor
  • It removes moisture using a desiccant
  • It plays a role of filtering out contaminants. No one wants a contaminated A/C system. Contaminants can lead to accelerated parts wear and damaging corrosion.
  • Symptoms of a damaged receiver or dryer:

  • Poor air conditioner performance
  • Inability of defroster to remove moisture from glass and windows
  • A certified technician will be able to do a comprehensive diagnosis of your AC and determine what the problem could be. He/she will then service your AC and make any recommendations that would be suitable for you in the future. He will also recommend regular maintenance for your system to always give the best performance and to be able to last for several years without replacement.
