Tip & How-To about Heating & Cooling


What is a condenser?
Is a device or unit used to condense vapor into liquid. A condenser is simply one component of an air conditioner. Whether you have an outdoor air conditioner or a window unit air conditioner your air conditioner contains a condenser.
Condensers are used in outdoor air conditioning systems as well as heat pump systems. Condensers in an air conditioning unit have very few controls. They will have an on and off switch. Occasionally these air conditioners will also have a brown out option. This option shuts down the compressor when the electrical current is low.
A condenser is simply a heat exchanger. It compresses refrigerants into a hot gas to then condense them into a liquid. A condenser is a major component in a air conditioning or heat pump unit. It moves air across the coils to facilitate the transfer of heat.
In a heat pump unit the condenser has a few more features. It will have a reverse valve that allows the unit to switch back and forth between air conditioning and heating. Even when the unit is heating, it uses the condenser for defrosting the coils. If the coils become layered with frost it will effect the units effectiveness this is defrosted when the reverse valve switches to air conditioning mode to move the hot gases through the coils melting the built up ice. It will automatically switch back to heating mode once the ice is cleared to once again heat the home.
To keep your unit in good operating condition it is vital to keep the area around the condenser clear of all debris as well as keeping the filter clear of dust and dirt. A clean machine makes a happy machine. A happy machine will keep you cool during the summer months and warm during the cold months. It is suggested to change the units filters when they become dirty, depending on your area and conditions near your home this may be as often as once a month or as seldom as every 3 to 6 months. You will have to pay close attention to your units needs to decide the right time to change or clean your unit’s filters.
It is very important no matter what type of unit you have to prevent the blockage of the condenser. If the condenser becomes block it can effect the units efficiency or even cause the until to completely fail. For this reason it is one of the most important components of a cooling or heating system. A condenser allows the maximum airflow to the unit.
Keeping you condenser in good running condition will not only prolong the life of your heat or cooling system but also provide you with the most efficient heat and cooling system saving you money on heat and cooling.www.victorwod1234.blogspot.com

why is water in my ac unit power cord?

cold air condenses water vapor into fluid. If your power cord is below your air conditioner, you could move it, or create a barrier to prevent condensed vapor ("water") from flowing down the cord.

Condensation is the change in matter of a substance to a denser phase, such as a gas (or vapor) to a liquid.[1] Condensation commonly occurs when a vapor is cooled to a liquid, but can also occur if a vapor is compressed (i.e., pressure on it increased) into a liquid, or undergoes a combination of cooling and compression. Liquid which has been condensed from a vapor is called condensate. A device or unit used to condense vapors into liquid is called a condenser. Condensers are used in heat exchangers which have various designs, and come in many sizes ranging from rather small (hand-held) to very large.
The water seen on the outside of a cold glass on a hot day is an example of condensation.

Goodman unit runs and at the a-coil there is a piston where your suction and liquid lines connect. On the liquid side the piston is cold but warm on the other side of piston. A/C unit will not cool.

That piston is the metering device. On the liquid line, before the metering device it is always warm (this is sub cooled, high pressure liquid), but should flash to low pressure, lower temperature vapor once it passes through the metering device. The suction and liquid line never connect together.The liquid line brings liquid from the condenser to the evaporator. The suction line brings super heated vapor from the evaporator to the compressor. Since the unit does run, I'd have to put a gauge on it,but if I had to guess, I'd guess you have high head pressure. Check for dirt or debris on the condenser, check for proper clearance of the condensing unit and check for operation and directional rotation of the condenser fan. This could also be the result of an over charge.

sunbeam air conditioner 7500 btu model sck 7500dr, not cooling anymore what can be the problem

It could be a number of things. Compressor could be finished, a clogged metering device,a dirty condenser, low or no refrigerant (freon), blocked return air register. Bird's nest in the unit's condenser(in the rear), broken conductor, blocked or restricted liquid line, inoperable condenser fan or just about anything.Just replace it.

it leaks out of a tube in the back....it has only just started and have had the machine for a while now

Depending on humidity all air conditioners make a varying amount of condensate water,
its simply akin to placing a cold can of soda on a table and watching it grow wet on the exterior of the can as the moisture in the air condenses from its vapor form into a liquid form or state.
AC units have a splash ring on their condenser fan blades perimeterthat hurls the consensate upon the hot condenser coils thus evaporating the moisture usually, if it cant , it will do as you see.
I am assuming its a window or wall AC unit and not a central AC system.
If its a central system there are 2 drains, a primary and a secondary, the primary will be routed to a place you wont ever notice generally, like a drai or outside intoa planter etc.
If your furnace is in the attic a secondary will terminate i a noticable area like above a bathroom sink or outside a window where you will see the water where it never was , signalling a need to assess the condensate lines primary functioning. All AC units will make condensate moisture and it alone isnt an issue .
