If your air conditioner isn’t cooling
your house in a hot summer day of August, buying an air conditioner becomes
worthless. There can be many reasons behind this. Some of which are technical
faults and some are non-technical. So, here are a few reasons why your air
conditioner is ineffective –
4 Reasons Why
Your AC isn't Functioning Properly
1. Oversized Air
Many people think
that bigger air conditioner works more efficiently than the smaller one. But
this isn't true for air conditioners. When you install an oversized air
conditioner in your office space or home, it'll not work efficiently. Oversized
air conditioner fails to control humidity and temperature very badly and when
you install an oversized air conditioner, it'll frequently turn on-off its
compressor. As a result, your HVAC unit won't be able to remove humidity from
your home or office space. To choose the right sized AC for your space, you
need to consult with an HVAC professional. An HVAC professional will tell you
the right size for your space. Don't try to ask your builder because they'll
try to suggest you bigger air conditioner which won't bring any good to you. So,
before installing an air conditioner in your house or office space, make sure
that you contact an HVAC professional and buy the right sized HVAC system.
2. Dirty Coil
If your air
conditioner isn't working efficiently, there is a chance that your air conditioner
has a dirty coil. The condenser coil removes the heat from your house to
outside. When it gets dirty, it cannot transfer heat properly to the outside.
That makes the air conditioner less efficient. Also, when this happens, your
air conditioner unit will have to work more to provide cooling. If the
condenser coil gets dirty, your HVAC system won't be able to provide enough
cooling. So, if you don't want to face this situation, you'll have to maintain
your HVAC unit properly and should go for a regular HVAC maintenance check.
3. Dirty Air
The dirty air
filter also makes your air conditioner less efficient as a dirty condenser
coil. Air filter purifies the air by blocking all the small particles and
debris. As its main function is to prevent all the dust and debris, it gets
dirty very quickly. When you have a dirty air filter, the air filter won't
allow the air conditioner to run at its full efficiency. As a result, your air
conditioner's cooling capacity will get lower and won't work efficiently. To get
rid of this problem, you'll have to change your air filter once every 2-3
months depending on the usage. If you live in a polluted city, you may have to
change it more frequently. It completely depends on the outside air quality.
Also, you can go for a regular HVAC maintenance check to solve this
4. Negative Air
If your air
ventilation is poorly designed, you'll face this negative air pressure problem.
So, how to know whether you have a negative air pressure problem or not? When
you open the door of your space, if you notice
that the airflow is coming inside from the outside with heavy flow, then you’ve
got a negative air pressure problem.
So, when the
outside humidity is high, inside air of your home will try to balance humidity with
the outside air. As a result, high humidity air will enter your space. When
high humidity air enters your space, it'll be very difficult for your HVAC
system to control the humidity. As a result, your air conditioner will become
ineffective and inefficient. To solve this problem, you'll have to change the
air ventilation system in your house.
