THE LIQUID LINE DRIER IS THE FIRST LINE OF DEFENSE AGAINST DAMAGE TO YOUR AIR
CONDITIONER’S COMPRESSOR!

 

An air conditioner’s liquid line drier is the first line of defense against
moisture (water) getting into your air conditioners compressor and doing
irreparable damage. Today most liquid line driers are what is known as
solid-core zeolite desiccant filter-driers. In the past liquid line driers used
compounds such as activated alumina, silica gel, calcium chloride, and calcium
oxide as a dessicant, but these older versions of the driers had to be installed
in a very specific way or they were subject to crumbling on the inside, allowing
the dessicant to escape the line drier and add to the chemical cocktail
technicians attempt to avoid in the first place.

 

Rusted Liquid Line Drier

 

 

An air conditioner is a  system of integrated parts, chemicals, materials, and
components that work and interact with each other to manufacture a specified
result. These interactions have enormous potential, when combined with the
incessant changes between warm and cold environments, to change or modify the
chemical nature of the elements as they move throughout the air conditioner.The
HVAC system itself, is comprised of a …

 compressor

condenser,

metering device

evaporator

copper lines,

oil

refrigerant

as well as other electrical & mechanical components

 

Each of the components within the system contain of a number of metals such as
the iron casting of the compressor, copper lines, steel condenser, aluminum
evaporator, brass valves and fittings, and perhaps still other metals in smaller
quantities.  Additionally, there are chemicals within these component parts
capable of interacting independently to create new chemical compounds capable of
damaging, and diminishing the equipment’s ability to perform it’s duties, and
seriously impacting it’s life expectancy. Some of the elements found within a
typical HVAC system would include … 

 

Hydrogen

Nitrogen

Oxygen

Moisture (water or other liquid)

Flux

Powder from the insulation

Shavings from component parts

 

. The moisture and oxygen are very active components that act as catalysts
themselves, and interact independently with various metals within the structure
of the equipment.These chemicals when mixed have the capacity to turn acidic,
which can eat the varnish coatings of the electrical winding’s deep inside the
compressor. The mechanics of a compressor are such that, while the compressor is
an enclosed unit, the compounds being compressed to perform the cooling action
actually run over the outside of the electrical and mechanical parts inside the
compressor. Should those compounds turn acidic or caustic, the compressor will
eventually fail and may even create a fire on the inside. The combination of
chemicals, heat, and flame in an interior compressor fire has been known to
create poisonous phosgene gas, otherwise known as mustard gas, which was used
extensively in World War I and accounted for a high percentage of the deaths in
that war.

 


AIR CONDITIONER REPAIR BEST PRACTICES DICTATE THAT THE LIQUID LINE DRYER SHOULD
BE REPLACED ANY TIME ONE REPLACES THE COMPRESSOR, OR ANY TIME THE INTEGRITY OF
THE COOLANT LINE IS BREACHED!

Brand new liquid line drier, ensuring safe, efficient compressor performance,
and minimizing the risk of fire.

 

The best way to be certain your liquid line drier is operating effectively is to
have your air conditioning equipment inspected yearly. Simple things like a spot
of rust, or a small dent, or a bend in the line itself can compromise the
integrity of a liquid line drier. Other times the desiccant on the inside can
become clogged, restricting flow, and creating insufficient levels of coolant in
the compressor. An experienced contractor will notice this by feeling the line
dryer with his hands, if one side is warm … and the other side is noticeably
cooler, that is a pretty good indication of a blocked passage within the line
dryer itself.  When replacing a liquid line dryer one should never use heat to
“un-solder”, or “un-braze” the dryer. And any time the compressor is changed, or
the integrity of the coolant line is compromised, best practices would include
replacing the dryer.

 


THE BEST WAY TO BE CERTAIN YOUR LIQUID LINE DRYER IS UP TO PAR IS TO HAVE YOUR
AIR CONDITIONER INSPECTED ANNUALLY BY A LICENSED AIR CONDITIONING CONTRACTOR!

 

 WE CAN HELP YOU WITH THAT!!!

WHAT THE NEWS PRESS HAD TO SAY ABOUT US

TELL MEL ____________________________________________________-

Second opinion needed for AC fix
_____________________________________________________ I don't usually do two air
conditioning columns in a week, but Monday's column touched a nerve. So I
thought I'd pass along some of the stories I've heard from AC company owners who
have called. The first story comes courtesy of Kurt Hartmann of Community
Cooling in Fort Myers. Hartmann gives free second opinions on other companies
repair or replacement estimates. Recently, a woman who lives in a North Fort
Myers mobile home park called him after another AC company had come to look at
her unit. Several weeks earlier the woman had installed a thermostat and the AC
worked fine. But when the weather turned cold, and she tried to get it to heat,
the unit wouldn't work. She called a company, which will remain nameless. The
technician removed the cover on the thermostat, examined it, and then went to
look at the unit. His diagnosis: She needed a new relay and transformer. Total
$2,300. Fortunately, the homeowner decided to brave the cold for a day and get a
second opinion. Her unit was only six years old and she couldn't believe it
needed such an expensive repair. When Hartmann's guy arrived, he too popped the
cover off the thermostat. There he saw a switch with two positions for the heat
- gas and electric. This thermostat had the switch in the position for gas, but
she, like most people in Southwest Florida has an electric unit. When the
thermostat was switched to the electric mode, the heater "worked like a champ"
Hartmann said.
