Air conditioner compressor is an
integral part of the HVAC system, and it’s placed outdoor. The primary function
of the air conditioner compressor is to pump the refrigerant through the HVAC
system. But while using the air conditioner, your air conditioner compressor
can start overheating, and when this happens, your air conditioner may stop
functioning. There can be a number of reasons behind air conditioner compressor
overheating, and it consists of both internal and external factors or
conditions. In this article, I’ll talk about 4 reasons for air conditioner
compressor overheating and their solutions.
Reasons for Air Conditioner Compressor Overheating & Their Solutions
Dirty Air Conditioner Air Filter
Air conditioner air filter
blocks dust and small particles from entering your space and keeps the indoor
air clean. As it blocks dust and debris, it gets dirty quickly, and when you
don’t change the air conditioner air filter regularly, dust starts to
accumulate in your HVAC system.
When dust and small particles
accumulate in your HVAC system, they reduce the airflow of your air
conditioner. As a result, your air conditioner doesn’t get enough air to reach
your desired temperature, and overall efficiency starts declining. When the air
conditioner doesn’t get enough airflow, it has to work harder to produce the
desired cooling, and because of this, your air conditioner has to put a lot of
stress and strain on the electrical system of your air conditioner. Eventually,
your air conditioner starts to have more wear and tear and overheating
To prevent this from happening,
you’ll have to change your air conditioner air filter regularly. The ideal time
of changing an air conditioner air filter is between 60 to 90 days. However,
you may have to change the air conditioner air filter a bit earlier if you live
in a polluted area or city. To know the exact time, you should contact an HVAC
professional and schedule an HVAC maintenance checkup.
Low Refrigerant Level
Refrigerant plays a key role in
producing cool air. It absorbs the heat from your space and releases it to the
outside condenser unit, and thus, your air conditioner produces cool air. But
when the refrigerant level is low, your air conditioner won’t be able to remove
the heat from your space efficiently.
The compressor is the heart of
an HVAC system, and it’s designed to match with the refrigerant charge. When
the refrigerant level gets low, the compressor starts overworking to produce
the desired temperature. As a result, the compressor starts overheating, and
due to compressor overheating, your air conditioner unit will stop working
To prevent this problem, you’ll
have to go through regular HVAC maintenance checkups. When you go through a
regular HVAC maintenance checkup, an HVAC professional will check all the parts
and liquids, including your air conditioner's refrigerant. If the HVAC
professional finds any faults in your air conditioner, you’ll be notified about
the problem and can take action quickly to resolve it.
Many homeowners in the US don’t
consider the size of their space and buy a small or large air conditioner for
their home or office space. When you buy a small air conditioner for your
space, your air conditioner compressor will have to work harder to produce the
desired cooling. But most of the time, your air conditioner compressor won’t be
able to produce the desired cooling for your large home or office space and
will have to run longer. As a result, your air conditioner compressor will have
to go through a lot of stress and strain, and that eventually cause the air
conditioner compressor overheating.
That’s why while buying an air
conditioner, you’ll have to consider the size of your space. To know your air
conditioner's accurate size, you should contact an HVAC professional and buy
accordingly. Thus, your air conditioner compressor won’t have to work longer,
and you’ll get the desired comfort from your air conditioner.
Outdated Air Conditioner
If your air conditioner is more
than 10 years old, it’s high time that you changed your air conditioner. When your air conditioner is more than 10
years old, there is a high chance that the parts of your HVAC system are
wearing out. As a result, your air conditioner compressor won’t be able to do
its job properly, and eventually, it’ll start to overheat.
That’s why if you have an old
air conditioner, you should replace it as soon as possible.
