Air conditioner replacement service

Air conditioners over the years get old and some of their parts get worn out and some have to be replaced. There are great qualified technicians offered by service companies who can replace parts or change the performance of the system to achieve higher performance. The technicians mostly do AC System Repair/Replacement of the major and minor components:

  • Compressors
  • Evaporators
  • Condensers
  • Tubings and thermal expansion valves
  • Driers and accumulators
  • Motors controlling the blowers and blower motor resistors
  • Seals and pipes
  • It is important to understand how some of this replaceable functions work in order to understand how to maintain them and avoid the cost of replacing the parts. Most air conditioners are made up of five major components, the compressor, the condenser, the evaporator, the thermal expansion valve and the drier or accumulator. The compressor is the central part of every AC system. The compressor:

  • Pressurizes the refrigerant and pumps it to all other parts.
  • Senses temperature changes using the compressor clutch
  • Powered by the serpentine belt when it is located in the car
  • The condenser turns hot refrigerant gases into liquid using electric fans that cool the refrigerant. Air passes through the condenser, turning the hot refrigerant gas into a condensed, cooler refrigerant liquid. The receiver or dryer is found on vehicles with a thermal expansion valve. It is responsible for trapping all harmful debris, moisture and liquids from reaching the compressor and other vital AC parts. It separates gas from liquid. If liquid isn’t contained in the dryer, it can enter and destroy your compressor.

    The accumulator is found in cars with a thermal expansion valve and is used to absorb moisture and contaminants using desiccant and filters. It is important to always change the filters so they don’t become moldy and start smelling.

    The orifice tube also known as the thermal expansion valve is located between the condenser and the evaporator. It monitors the pressure and temperature of your AC system in order to determine the exact amount of refrigerant that can safely enter your evaporator. It also traps contaminants and ensures you don’t freeze.

    The evaporator is responsible for cooling air and removing moisture. When the refrigerant enters the evaporator it is cooled even further then air is blown across it. The air takes up the coolness from the refrigerant and deposits its heat on it. The refrigerant heats up and changes state from liquid to gas and the cool air then enter your compartment. The refrigerant is then recirculated in the system many times over to keep you cool.

    As your AC system ages it reduces its efficiency and this could reflect on your utility bills. The best option is to replace the unit with a higher performing unit.AC unit repair of parts is easy for most service companies to do as they stock the various parts and they will be ready to do replacement of any parts that cannot be fixed.
