Cleaning the coils with in the first year no. Rec to have it service once a year though. Cleaning them every other year. Look at them if you take a flash light and can see light thought the other side they should be good. You can also take your garden hose and clean them your self. Just dont get to close that you bend the fins.

How a Central Air Conditioning System Works
amn_howac.jpg


Facts:
  • The typical central air conditioning system is a split system, with an outdoor air conditioning, or "compressor bearing unit" and an indoor coil, which is usually installed on top of the furnace in the home.
  • Using electricity as its power source, the compressor pumps refrigerant through the system to gather heat and moisture from indoors and remove it from the home.
  • Heat and moisture are removed from the home when warm air from inside the home is blown over the cooled indoor coil. The heat in the air transfers to the coil, thereby "cooling" the air.
  • The heat that has transferred to the coil is then "pumped" to the exterior of the home, while the cooled air is pumped back inside, helping to maintain a comfortable indoor temperature.
  • Central air conditioning can also be provided through a package unit or a heat pump.

Benefits:
  • Indoor comfort during warm weather - Central air conditioning helps keep your home cool and reduces humidity levels.
  • Cleaner air - As your central air conditioning system draws air out of various rooms in the house through return air ducts, the air is pulled through an air filter, which removes airborne particles such as dust and lint. Sophisticated filters may remove microscopic pollutants, as well. The filtered air is then routed to air supply ductwork that carries it back to rooms.
  • Quieter operation - Because the compressor bearing unit is located outside the home, the indoor noise level from its operation is much lower than that of a free-standing air conditioning unit.

KNOWING ABOUT CONDENSER


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

Save cost with some precautions


Precautions to be taken in air conditioners and to save cost.

These are some useful precautions to be taken in air conditioners (A/C).Improper refrigerant charge can damage your compressor, which is the heart of your air conditioning system; this is an expensive air conditioner repair. Systems improperly charged will cause increased electric bills because this will reduce the efficiency of your air conditioning system. The proper refrigerant charge will provide longer equipment life, lower your utility bills and reduce the need for air conditioning service.
A dirty condenser coil (outside unit) will reduce your air conditioning systems ability to remove and reject heat from your home. This will cause your system to run longer and increase your electric bills. The benefit of a clean condenser coil is proper heat rejection, reduced run time and lower energy bills. A dirty air conditioning condenser can lead to system failure and the need for you air conditioner to be repaired, dirt and house dust that escapes through your air conditioning filter can cling to the cold moist coil. This will restrict the air flow through the coil reducing your air conditioning system of performance and capacity. Maintaining the evaporator coil will ensure that proper air flow is delivered to all areas of your home, increase comfort levels, provide a cleaner healthier indoor environment. Inspecting and changing your air filter on a monthly basis will help prevent air conditioner repairs.
As your air conditioning system removes heat from your home, humidity is extracted from the air. The condensation created by warmer air passing over a cold coil must be drained from your system. This is done through a condensate drain line. The drain must be checked and cleared of algae build up or foreign particles clogging the drain, which could cause water damage to the ceiling or floors of your home. By keeping your air conditioner drain line clear you will reduce the need for air conditioning service and overflow problems which can result in water damage. Proper draining will also aid in maintaining indoor humidity levels.
Cause of air flow
Dirty blower wheels can affect the air flow to your home; limit your air conditioning system's capacity and your comfort. It can also spread dust particles which irritate sinus and allergies. A clean blower wheel and fan motor will provide maximum air flow, improved comfort levels and proper cooling. Most of air conditioner repairs are caused by dirt and the lack of maintenance.
Cause of electrical panel
Your thermostat should be properly calibrated. This will ensure accurate temperature control and operating cycle. This will save you on operating cost and assure your comfort level. Moving parts in need of lubrication can cause increased electrical consumption and air conditioner repairs. This is due to additional power required to overcome the resistance in motors and drive shafts that are not lubricated. Proper system lubrication will offer smooth motor and shaft operation, extended part life and less air conditioner repairs. The electrical components on your air conditioning system should be inspected regularly for signs of wear. Faulty electrical components can lead to very expensive air conditioning repairs. A thorough inspection will reduce the need for air conditioner service if the faulty or worn parts are replaced when found.
Carrying this tips help reduce the amount of air conditioner repairs you will encounter over your air conditioning systems lifespan. If you are in need of air conditioner service make sure the company you choose is licensed and insured to do the required repair work (warranty) .

97 Grand am v6 up & down idle. Driving =steady acceleration. I've changed, O2 sensor, throttle positioning sensor. Scan is still saying Random misfires? Get warm won't start.


P0300 Random misfire - lean condition , vacuum leak , low fuel pressure , fuel filter plugged partially , mass air flow sensor .
If the misfire is random, check for the following conditions:
?€¢
System Grounds: Ensure all connections are clean and properly tightened.


?€¢
MAF: A Mass Air Flow (MAF) sensor output that causes the PCM to sense a lower than normal air flow will cause a lean condition.


?€¢
Air Induction System: Air leaks into the induction system which bypass the MAF sensor will cause a lean condition. Check for disconnected or damaged vacuum hoses, incorrectly installed or faulty crankcase ventilation valve, or for vacuum leaks at the throttle body, EGR valve, and intake manifold mounting surfaces.


?€¢
Fuel Pressure: Perform a fuel system pressure test. A faulty fuel pump, plugged filter, or faulty fuel system pressure regulator will contribute to a lean condition.


?€¢
Injector(s): Perform injector coil/balance test to locate faulty injector(s) contributing to a lean or flooding condition. In addition to the above test, check the condition of the injector O rings.


?€¢
EGR: Check for leaking valve, adapter, or feed pipes which will contribute to a lean condition or excessive EGR flow.

Reviewing the Fail Records vehicle mileage since the diagnostic test last failed may help determine how often the condition that caused the DTC to be set occurs. This may assist in diagnosing the condition.

Hello, sounds like it is either a low charge or lack of airflow, what type of filter are you using? sometimes those filters that claim to be super effecient will actually cut down on your airflow and cause the ac to freeze up.

Condenser Coil Cleaning Condenser Coil Cleaner


One of the most important things to maintaining a highly efficient Air Conditioner is keeping the condenser coil clean. To make your condenser coil cleaning as easy as possible you need to know what to use to clean your coil.

There are a number of different things that can be used to clean your condenser coil. It does not matter whether you are cleaning a central air conditioning unit or a window air conditioning unit. What does matter is the type and location of the coil and the amount of dirt that is in the coil.

When looking at the type of coil cleaner to be used, make sure that the chemical being used is compatible with the type of metal that the coil is made out of. Some chemicals and certain metals do not get along well and should be avoided.

Also, if you condenser coil is severely plugged then a foaming type coil cleaner is a must have item. If the condenser coil just needs to be washed down and is not completely plugged then a mild detergent may be just the tool needed to do the job.

For many units that have regular cleanings, a good quality detergent similar to what you use to wash your car, will work just fine. The main object of the cleaning is to remove the dust, dirt, and grime from the coil to promote better air flow through the coil. If the coil is just plugged with grass or dandelion seeds them a simple hosing off with the water hose may do the trick.

If a foaming cleaner is need to clean a neglected or very dirty coil then look up your local heating and air conditioning supply house and purchase a coil cleaner specifically for cleaning condenser coils. Most of these products are for professional use only and care is needed when using and handling these products.

Condenser coil cleaning can be done by the homeowner if proper care is taken and it will keep you air conditioning unit running great whether it is a central air conditioning unit or a window air conditioning unit. Once you know what to do and how to do it you may find that you will be cleaning your condenser coil a number of times a year to insure top performance from your unit.

Air Conditioning - Cleaning the Condenser Coil


Normal 0 MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman";} Air Conditioning works by exchanging heat from inside a building to the outside air. To do this some very basic refrigeration principles need to take place. One of the most critical pieces that make this happen is the condenser coil. This is usually the aluminum coil the surrounds the air conditioning compressor.
What happens inside this outdoor unit is a very basic state change of the refrigerant inside the air conditioning unit. The refrigerant that changes from a liquid to a gas inside the indoor coil moves to the outside where the compressor compresses the gas under high pressure. When this happens the gas also becomes very hot. The hot gas then leaves the compressor to start traveling through the many feet of tubing in the condenser coil. As the gas cools it changes back to a liquid form going back indoors to start the cycle all over again.
Big problems start when the condenser coil becomes so blocked up with dirt that the hot gas in the condenser coil does not cool enough to change the hot gas back to a liquid form. If this happens the cooling process does not happen and then air conditioner runs but is not cooling. The compressor starts to get very hot and the ultimate result will be the death of a compressor. For these reasons the condenser coil must be kept clean and free of debris at all times when the air conditioner is running. Cleaning the coil is a fairly simple process, Here are a few guidelines to follow when doing this.
To clean the coil a few simple tools are needed. A garden hose with a nozzle, wrenches to remove the condenser fan, a garden sprayer for applying the cleaning solution. The first thing is to disconnect the power to the outdoor unit. There should be a disconnect switch of some type near the condenser. Then remove the fan from the condenser unit. Usually this will be the top of the unit. The fan can usually be laid aside carefully without disconnecting the wires to the motor. Carefully wet down the coil with the garden hose. If you have very high pressure water where you live be careful that the water pressure does not bend over the fins on the coil. These are very thin and fragile. If they get bent over the air will not be able to freely flow through them. Using the cleaning solution from the garden sprayer, coat he inside and the outside of the coil. Let the solution work on the dirt build up before washing it off. If you use a foaming type coil cleaner then let the foam cook the dirt out of the coil. Then use the garden hose to wash the dirt out of the coil. I often work from the inside spraying out through the coil. This is the reverse of the usual air flow and it washes the dirt out easier. Rinse the coil with water till it is clean with no more dirt or cleaner coming out. Replace the fan and start the unit back up.
The cleaning solution for the condenser coil can be any good household cleaner. Many automotive type radiator cleaners will work well. For very dirty condensers it would be good to buy a foaming coil cleaner made specifically for cleaning condenser coils. A local plumbing and heating supply house should stock coil cleaning solutions. Most of these solutions are very strong chemicals. Be sure to wear gloves and eye protection when working with them.
By keeping your air conditioning condenser coil clean, you will help to have your air conditioner running at the best efficiency possible. A clean condenser coil is one of the easiest ways to save electric while running your central air conditioning system. A clean coil will allow your compressor to run cooler and help it to last longer. Your condenser coil should be thoroughly cleaned at least once a year. If in you live in very dirty areas like along a dirt road you may need to clean the condenser coil more often. Also do not do things that would clog up the coil. Blowing grass clippings into the condenser coil is one common thing that happens. Keep shrubbery from growing into and around the condenser coil. This stops the air flow to the coil. Large flowers planted too close to the coil can do the same thing.
As you can see there are many things that can cause your air conditioner to work harder and cost you more money. By taking a the time to look over things and give it a cleaning you can save a lot of money.

Not blowing cold air


Hi,
There can be a couple of things that could be happening...
The first and easiest thing is to check the air filter. Make sure that it is clean... clean it or replace it. Next check the air vents to make sure that they are open and giving you good air flow...
Also check to make sure that you are not icing up on the indoor coil... ice will tell you that you are low on refrigerant. You also could be low and not be icing over, but you would need to have gauges on the unit to check that.
Finally check and clean the outdoor coil...this also can give you problems if the heat is not being removed from the outdoor unit efficiently...
You may also have a unit that is sized in such a way that it hits the balance point at about 85...that means that your heat gain is equal to the capacity of the unit...I often try to size them for about that here in Northern PA. because wqhen seldom get hotter then that and the unit then is much more effective at removeing humidity at lower temperatures...
