7 Common AC Problems and How to Deal with Them
Kick start the summer by keeping your air conditioner in perfect working
condition. Before we tell you about the most common problems that occur in AC
equipments, along with their easy do-it-yourself solutions; before you assess
the present condition and check whether your air conditioning equipment needs
repair or not, ensure that all windows and doors are sealed shut to make sure
the airflow is constant. Also, it is better to check if the thermostat settings
are correct, if the air filter is clean and if the circuit breakers are
functioning well, etc. It is to be noted that periodic maintenance can come
handy in the prevention of breakdown and expensive air conditioning repair
1. Dysfunctional thermostat – An incorrectly calibrated or
malfunctioning thermostat might result in an air conditioner that refuses to get
switched on. The problem can be solved by recalibrating the thermostat, using
the equipment manual. If the issue persists even after recalibration and setting
the thermostat to the lowest temperature, it might imply that the device needs
to be replaced by a qualified technician.
2. Equipment does not get switched on – If the conditioner does
not get switched on, it means that it is not receiving input power. This might
happen because of a tripped circuit breaker, or a blown-up fuse, or loose wires,
or issues with the thermostat. To address the issue, check for power supply at
various parts of the inlet, analyse at which point the influx of electricity
stops, and take appropriate corrective measures.
3. Low efficiency – If the refrigerant level is low, it could
imply that there is a leakage along the flow line. It is only with the right
level of refrigerant that the right temperature and humidity can be achieved.
This issue would need the attention of a qualified technician, as the source of
leakage needs to be tracked down and fixed, before topping up the refrigerant or
replacing the entire unit. If left undetected for long, this issue might lead to
low efficiency, high electricity bills, and high repair costs.
4. Condenser issues – The condenser performs the vital function
of discharging the collected heat from within the house, to the surroundings. As
it is exposed to the environment, it is prone to be subjected to dirt, dust,
weeds, grass, etc., which might hamper the working of a condenser, if left
unclean. To resolve this issue, keep your outdoor unit clean and neat, by
cleaning it occasionally and removing weeds.
5. Evaporator issues – The evaporator coil comprises
refrigerant fluids that absorb heat and transfer it to and from your home. When
airflow into the evaporator gets restricted, because of low refrigerant level or
dirty air filter, layers of ice can get gradually deposited on the coil.
Consequently, your home could get warmer and warmer, even if the air conditioner
is switched on and running in full blast.
6. Duct leakage – The improper air flow inside your home could
be attributed to leaking or dirty ducts. While rats or other rodents might be
responsible for leakage, it is essential to recognise this issue at the
earliest, lest you get hefty electric bills. This problem can be taken care of
by a qualified professional.
7. Noisy AC systems – The noisiest part of an AC equipment is
the motor of the fan. If clogged with dust and dirt, the bearings and belts
inside the motor might deteriorate, causing them to overwork, heat up, and cause
excessive noise. If well versed in the technicalities of motors, you could
change it by yourself, although it is advisable to seek the assistance of a
While quick fixes can help in resolving leaking ducts and improper AC
installation issues, these are not long-term solutions. Get your AC equipment
inspected and serviced by trained and verified professionals from
They will check your air conditioning systems refrigerant leakage, electric
wiring issues, sensor fiascos, and improper condensate drains and provides a
thorough servicing at a nominal price.
