AC Service

Why AC Service is Required?

A mold or mould is a fungus that grows in the form of multicellular filaments called hyphae. In contrast, fungi that can adopt a single-celled growth habit are called yeasts. Wikipedia

When that stuff gets pulled into an air conditioner and finds a wet coil, it sticks.
It's a mix of all kinds of things.

  • A lot of particles (pollution, dirt, dead bug parts...)
  • Carpet fibers
  • Pet dander.
  • And skin flakes.

And Over the time, that gunk creates its own little ecosystem as,

There's life in these particles

Skin flakes have proteins and fatty acids in them. Bacteria live on the proteins; have eventual waste product ammonia, which creates smell something like urine coming from the air conditioner.

Bacteria living on fatty acids with a different waste product; creates smell like body odor.

Without proper care and maintenance of AC, mold grows on the inside which could lead to health problems like wheezing, congestion and throat irritation.

Who says this thing?

Living with a moldy air conditioner “would increase your chances of having a respiratory infection,” says Mark Mendell, Ph.D., an affiliate scientist at Lawrence Berkeley National Laboratory who has studied the health effects of ventilation systems.

Chris Regan, senior test project leader in Consumer Reports’ air-conditioner lab, says harmful mold can first show up on the air duct just inside air-conditioner louvers—the openings where cold air comes out—as clusters of tiny black spots.

what is the Solution?

Consumer Reports says, get your AC service at the start of the season and then once a month after that.

Examining your air conditioner and Cleaning the louvers is a good first step, but only a partial solution.
  • You have to get clean, the particulates like diesel exhaust, pollution and other allergens, that can cause health problems such as asthma and lung inflammation.
  • A dirty filter can restrict airflow and can cause freeze ups.
  • Drain line is required to be cleaned out of mold.

You should not clean your AC using a power washer yourself, as you can damage it by bending the coils. Hire a professional for the AC Service

FAQ - Air Conditioner

  1. AC should be serviced at least once a year during the start of summers.
  2. It depends upon following requirements,
    1. Operating time of AC: In India we have all kind of persons living near us, some keeps their AC ‘ON’ for whole day, and some operate only during night, and some for two hours before going to sleep.
      So, the funda is simple as long the operating time of AC more frequently is the requirement of service.
    2. Surrounding conditions: There are different surrounding conditions according to the situation of the building i.e.,
      1. Park facing
      2. Main road near them
      3. Commercial Building in market
      4. Commercial building in Motor Market
      5. Society near highway
      6. House near farm
      7. House in Sector
      8. Near a under construction building

Different surroundings, different amount of dust, dirt, pollution etc., More is the value of dust, dirt and pollution, more is the requirement of service of AC.

AC or “air conditioner” works on the principle of compression of refrigerant gas. It has many different parts assembled together to create cooling effect. Main parts are:

  1. Compressor
  2. Condenser Coil
  3. Expansion Valve (Capillary Tube)
  4. Evaporator Coil
  5. Condenser fan Motor with fan Blade
  6. Evaporator Blower Motor with blower
  7. PCB (Control Circuit)

If any of the above part becomes faulty, AC stops working and,
with cleaning of these parts smooth working of AC is insured.
If we do not get our AC service regularly, it leads to failure of AC through following steps,

  1. Compressor starts working extra to compensate the heat loss due to dirty condenser coil.
  2. Compressor starts overheating.
  3. During which starting and running capacitor might get burnt, and
  4. Compressor pumps oil with refrigerant.
  5. Oil gets stuck in part Capillary Tube, in this case Capillary Tube should be replaced with oil and gas.
  6. Now if Capillary Tube is not replaced, it results in full choking of gas, which leads to further overloading of compressor.
  7. In that event, even compressor might get burnt out. In this case compressor has to be replaced.

There are many possibilities that can cause AC system to freeze up:

  1. Dirty filter: Dirty Filter results in low air flow, which further results in freezing up of Evaporator coil
  2. Low refrigerant: Whenever there is low refrigerant value in AC, it results in low discharge pressure/temprature and suction pressure, which further results in freezing up of AC.
  3. Dirty evaporator coil: When evaporator coil will become dirty, there is low airflow and it freezes up.
  4. Defective blower motor or relay: A blower motor running at low speed, sometimes not running at all causes freezing.
Whenever the pressure/ volume of refrigerant gas is low then the required pressure/ volume, gas charging is required.
Here main thing to note is how gas pressure / volume get low:

  1. Leakage: Leakage of gas can be due to several reasons, i.e.,
    1. Loose flaring nut joints: Split AC, sometimes flaring nut joint get loose due to overheating of compressor/ outdoor unit due to following reasons,
      1. When outdoor unit is placed under direct sun
      2. When AC is used above its capacity, i.e., when AC is running regularly for long hours, when area is too big for AC to attain/maintain desired temperature
    2. Leak Brazing joints: Brazing is done at several points in outdoor and indoor unit, and when copper pipe is required to be joined, gas is leaked if at any point brazing is not done properly
    3. Puncture of Copper pipe
    4. Puncture of condenser coil/ evaporator coil.
  2. Choking of Gas: When Compressor starts overheating.
    1. Compressor pumps oil with refrigerant.
    2. Oil gets stuck in part Capillary Tube, resulting in choking of gas.
  3. Compressor Replacement: When ever compressor is replaced, Refrigerant gas charging is required.
  4. Increase in Length of copper pipe connecting indoor unit and outdoor unit

Electricity bill can be reduced by following ways:

  1. Installation of proper capacity of AC with respect to heat load of area.
    Heat Load calculation can be done by a professional through measurement of room but when choosing for home there is no requirement of such professionals. There is simple funda:

    1. 1 ton AC = 10*10*10 feet room
    2. 1.5 ton AC= 15*15*10 feet room
    3. 2.0 ton AC=20*20*10 feet room
  2. Operate AC at 22°C to 25°C Many of users think that, operating the AC at 18°C would cool the room fast as compared to 22°C setting, which is completely wrong. It doesn’t make any difference if you operate your AC at any temp. On the amount of cooling that your AC provide at a time. Only difference that it makes is,
    1. if user set the desired temp at 22°C, the compressor would stop at 21°C at again restart at 23°C
    2. and if user set the desired temp. at 18°C, the compressor would stop at 17°C at again restart at 19°C.
    3. So if user operates the AC at 22°C to 25°C the compressor would stop early as compared to 18°C, which helps in reducing the electricity bill.

Compressor of AC stops working due to following reasons:

  1. Compressor is fully damaged
    1. Compressor motor winding is brunt out
    2. Compressor piston is stuck
  2. Due to electrical faults
    1. Thimble brunt out
    2. Connecting Wire Break
    3. Faulty Starting Relay
    4. Faulty Starting Capacitor
    5. Faulty running Capacitor
    6. Faulty Programmed Control Circuit Board (PCB)
Main tip from our Team is, If any customer keeps on using faulty AC, one fault leads to another fault, resulting in increase in cost of repairing,
So, whenever there is less cooling in AC, Shutdown the AC and
Please feel free to call us

Water Leakage in AC can be due to following reasons:

  1. Dirty Indoor Unit
  2. Dirty Drain Tray
  3. Dirty Back Drain tray
  4. Choked Drain Pipe
  5. Improper Installation of AC

Proper cleaning of indoor AC-unit means

  1. Cleaning of Dust Filters
  2. Cleaning Of Evaporator Coil, From Front as well as From Back
  3. Cleaning of Front drain Tray and back drain tray
  4. Cleaning of PCB Section
  5. Cleaning of Blower
  6. Cleaning of Whole plastic body
  7. Checking of Copper Pipe Insulation behind Indoor Unit
  8. Cleaning of Flexible Drain Pipe attached with Indoor unit
