AC should be serviced at least once a year during the start of summers.
It depends upon following requirements,
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.
Surrounding conditions: There are different surrounding conditions according to the situation of the building i.e.,
Main road near them
Commercial Building in market
Commercial building in Motor Market
Society near highway
House near farm
House in Sector
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:
Expansion Valve (Capillary Tube)
Condenser fan Motor with fan Blade
Evaporator Blower Motor with blower
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,
Compressor starts working extra to compensate the heat loss due to dirty condenser coil.
Compressor starts overheating.
During which starting and running capacitor might get burnt, and
Compressor pumps oil with refrigerant.
Oil gets stuck in part Capillary Tube, in this case Capillary Tube should be replaced with oil and gas.
Now if Capillary Tube is not replaced, it results in full choking of gas, which leads to further overloading of compressor.
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:
Dirty filter: Dirty Filter results in low air flow, which further results in freezing up of Evaporator coil
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.
Dirty evaporator coil: When evaporator coil will become dirty, there is low airflow and it freezes up.
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:
Leakage: Leakage of gas can be due to several reasons, i.e.,
Loose flaring nut joints: Split AC, sometimes flaring nut joint get loose due to overheating of compressor/ outdoor unit due to following reasons,
When outdoor unit is placed under direct sun
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
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
Puncture of Copper pipe
Puncture of condenser coil/ evaporator coil.
Choking of Gas: When Compressor starts overheating.
Compressor pumps oil with refrigerant.
Oil gets stuck in part Capillary Tube, resulting in choking of gas.
Compressor Replacement: When ever compressor is replaced, Refrigerant gas charging is required.
Increase in Length of copper pipe connecting indoor unit and outdoor unit
Electricity bill can be reduced by following ways:
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 ton AC = 10*10*10 feet room
1.5 ton AC= 15*15*10 feet room
2.0 ton AC=20*20*10 feet room
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,
if user set the desired temp at 22°C, the compressor would stop at 21°C at again restart at 23°C
and if user set the desired temp. at 18°C, the compressor would stop at 17°C at again restart at 19°C.
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:
Compressor is fully damaged
Compressor motor winding is brunt out
Compressor piston is stuck
Due to electrical faults
Thimble brunt out
Connecting Wire Break
Faulty Starting Relay
Faulty Starting Capacitor
Faulty running Capacitor
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:
Dirty Indoor Unit
Dirty Drain Tray
Dirty Back Drain tray
Choked Drain Pipe
Improper Installation of AC
Proper cleaning of indoor AC-unit means
Cleaning of Dust Filters
Cleaning Of Evaporator Coil, From Front as well as From Back
Cleaning of Front drain Tray and back drain tray
Cleaning of PCB Section
Cleaning of Blower
Cleaning of Whole plastic body
Checking of Copper Pipe Insulation behind Indoor Unit
Cleaning of Flexible Drain Pipe attached with Indoor unit
