Question about Air Conditioners

1 Answer

Hi, We have two Paragon split systems which effectively cool our large home. One system is playing up. It started 3 days ago where there is water dripping from the front of the unit and the green 'run' light is now flashing. I tend to think it's blocked somewhere, buy my husband cannot find where to check this. Our outdoor units are both under the house with very effective ventilation but the last 3 days have been extremely humid, however the other system is running perfectly. Any ideas? Thanks, Judith Jefferys

More then likely the blockage is inside the a-coil section. At the drain. To get to it easier remove the pvc drain line. As the drain line comes out of the collection pan it goes into a pvc line the 90 degrees elbow goes to floor. So cut the line right before the elbow and unscrew the drain line from the a-coil. Be sure to have a towel to catch the water that will come out of unit as the blockage will be holding back a lot of water. Now sometimes the line isn't glued and would be able to just pull apart so try that first. Take the line and clean out with high pressure air out side cause it will get messy.

Now to do it like a pro would do it you would have to take the front cover off the a-coil. to gain access to the inside the unit. And remove any build up and blow from inside out.

If I was going to do it I would do both of these as to make sure line is totally clear.

Replace all line and fittings make sure you use teflon tape on the fitting that screws into the a-coil and glue that joint then when it goes to the 90 degree elbow don't have to glue. and if you need anymore help get back with me ok ken

3 split units run from one compressor one is not cooling


If there is 3 indoor units from one condensing unit
(6 pipes at outdoor unit) this is classed as a multi unit

All units will run correctly as long as they all require same mode, cooling or heating, if one unit decides to heat it will shut down until master unit decides to heat then it will start, for each unit to individually heat and cool there would have to be 3 pipes to each indoor,

What Size Air Conditioner Do You Need?


Air conditioning is not an exact science. There are many variables that can affect the way an air conditioning system performs. Also there are many factors that can affect the size of the air conditioner that you need. What I want to get into next is the problems that can show up from an air conditioning system being either too big or too small.

You have three estimates for central air conditioning in your house? Each estimate quotes you a different size unit. What do you do? Buy the middle one because they are between the other two? You may be happy and maybe not. Let me explain how this works and what the results are of not getting it right.

If the air conditioning unit is undersized, this is actually the lesser of the two evils. If your system is too small the worst that can happen is not nearly as bad. An air conditioning system that is too small will just not quite keep up on a very hot day. This usually is not that noticeable because as long as there is a difference between the inside and the outside temperatures you will still be happy. If the house is 80 degrees on a 95 degree day, you still feel rather cool in the house. The other advantages to the under sized air conditioning system is that you still get very good dehumidification on a mild rainy day when you still want some cooling and everyday that you are running the air conditioner you are saving money. Yes, even if the air conditioner is running longer, you are still saving money because it is using less power. The efficiency of the slightly undersized system will be much higher than the oversized system.

If your central air conditioning system is too big for the space being cooled you are actually worse off than if it was too small. Yes too large of a system creates some major problems! If your system has too much capacity and cools your house off too quickly, you will not get he secondary effect of that an air conditioner is designed to give you. The second benefit of your system is to dehumidify the air. If your system can cool the air very rapidly before it has time to take the water out of the air, you will not have a comfortable house. This also goes for any other building. Have you ever entered a store and it felt like you just walked into a refrigerator? That is because the equipment is so large that it is cooling the air, but not removing the water out of the air. The effect is a very uncomfortable cool. This can happen in homes, but usually to a lesser degree. The discomfort may not be that pronounced, but it will not be as comfortable as it could be.

So, as you can see size really does matter when it comes to air conditioning. The oversized system will give you an uncomfortable cool and waste energy at the same time. Neither of these things are something that you want. The undersized system may allow the temperature to creep up a bit on a very hot day, but will save energy and give great comfort most of the time. The ideal sizing is for the unit to be running constantly on the hottest day of the year and barely be able to keep up. When you are shopping for central air conditioning make sure that you tell the salesperson what you want and insist on seeing their heat loss/gain calculations for your building. No one can guess at what you need and do it correctly. Making sure you have the right central air conditioning for your house or building will make you comfortable and happy for many years to come!

Ductless Split Air Conditioner Review


Ductless split air conditioning units are the very best thing for some situations. Of course they can be installed in the place of most any central air conditioning unit. They also are a very good alternative to window air conditioning units. I will explore the use of these units more closely and look at how they can be used effectively.
One of the many problems encountered by the professional is when they are asked to install central air conditioning in an older home that was never designed with air conditioning as even a possibility. The walls may be very thick stone. Often they have very little or no insulation. The floor structures may be rough cut lumber. The joists spacing may be random. Walls and ceilings are plaster and lathe. Basically everything is stacked against any type of ducted central air conditioning. Many log style homes also are not very easy to get any kind of ducted central air conditioning installed. The open ceilings and the bare log wall design does not allow for any kind of ducting. I'm sure there are other situations. These are the ones that I have come across most frequently.
If you have a home or building that falls into one of these categories you may want to investigate installing a ductless air conditioner. This type of air conditioner can be installed in almost any home or building. The small indoor unit can be attached to the wall with a few screws. Most of the units only require that a three inch hole be bored through the outside wall. In new installations the units can be placed on inside walls with some fore thought and planning. For installation in older homes or homes that are already built you will want to plan the units to be on the outside walls.
The outdoor condenser units can be placed up to one hundred feet away from the indoor units. One outdoor unit can be used for many indoor units. Up to four indoor units can be attached to the same outdoor condenser. Some very advanced electronics will control the operation of the condenser and compressor to supply the refrigerant to the indoor air handler units that are running at the time. With variable speed technology the compressor and the condenser fan will only run as fast as needed. This technology has become very efficient in the last few years. You do not have to give up any efficiency with these ductless split units.
Another advantage to these mini split air conditioners is that they can be controlled to run only in the rooms that you actually need air conditioning in. If you are not going to be in a room you can shut down the unit. The units also have timers that can be set to turn the air conditioning on or off at preset times. If you are not going to be home all day the air conditioning can be setback or turned off. The timer will turn on the air conditioning so that you return to a cool house. Central air conditioning is very hard to zone effectively. Also with large central air conditioning systems the outdoor compressor will be running at full capacity even though only a few rooms amy be calling for cooling. There are some central air conditioning systems that are do some staging and variable speed technology. These are not as efficient or as effective as the ductless split technology.
Ductless split heatpumps are another great idea to look at. For a few dollars more you can also very easily have heat from your air conditioning mini split. Then especially in the mild spring and fall weather you can have some very efficient heat with out starting up that big monster of a furnace or boiler in the basement. In southern climates the heatpump version of the ductless split system may provide enough heat year around.
Ductless split air conditioning is definitely something that can solve many problems for some homeowners. Add to that the many advantages of these units and you will find that they are worth every penny that you will invest into them. As with any project like this make sure that you screen your contractor. These units are not for do it yourself people. There are many things that need to be done correctly for these units to work properly and efficiently. A refrigeration license is also required to install these air conditioners.
By doing a little research and hiring the right person you will enjoy many years of trouble free service from your new ductless mini split system.

We put in 2 fans under a canopy by the tennis courts, however, it is not giving the cooling effect we were hoping to achieve. It is open on all 4 sides. Would lowering the actual fan or changing the speed...


Are these box fans that you are trying to form a wind tunnel effect? If so, you be better off building "tunnel" for them. What seems to work the best (a poor man's air conditioner) is to build a push - pull tunnel with high volume fans. If you mount a drip system with a fabric (like filter material) where water saturates the fabric and then is exhausted out towards your tennis courts.

BUT you need large high volume fans for this to be effective for more than just a few feet away from the unit. BUT then it might also affect the tennis balls on the court. So it depends on what your objective is. If it is to keep watchers cool then it would work, if it is to cool the players then it could also affect the "play"!

Note: Camoflage neting is an effective way to shade something but not affect airflow.

I had bought a Lg inverter wall mounted unit it worked about 3 days but it didnt cooled the area and i decieded to changed the outdoor unit(compressor)according to repairman's advice .during the first...


You changed the compressor?? Why ??? These models do not normally have problems with this. I am conversant with most of the LS series and these have capacitor start compressors, which fail all the time. Generally all models have either a 45 /6 uf or a 50 /6 uf capacitor. If this fails, the compressor wont start, thus a no heat, no cool problem. If you have changed the compressor and made sure it is actually running, what is the operating pressure?? Suction side should be around 0 to -5 degrees c. Perhaps there isnt any gas in the system??
I assume by doing such a repair you are licensed to do so and have all the proper equipment to recharge the system ???

Normal cool temp 23 to 25 and heat mode 29 to 31. And regrading defrosting your pipelines no need any tray. You can insulate with Armaflex tube which is mostly used for best insulation. Hope there won't be further water leak.

For how long time to keep AC on?


The Department of Energy recommends occupied setpoints of 70degF Heat and 78degF Cool. During unoccupied times, it is recommended to setback Heat to 62degF and setback Cool to 85degF.
If your system is experiencing problems "catching up" from a setback temp setpoint, you will need to adjust these temperature setpoints to allow for your system's capabilities as well as your individual comfort needs.
In short, you will have to find a balance point between your body's comfort and your wallet's comfort.
You also want to make sure you keep your air filter clean. If you have access to your condenser coil (the part outside), wash it down from time to time using a water hose.
I don't know what your location is, but I'm including a link from the state of Michigan which offers some helpful information and advice on how to keep your system running efficiently & effectively.
I hope you found this information helpful. :-)

Mitsubishi Through the Wall Unit Does Not Remove Humidity


You were told incorectly. From what you are describing the unit is oversized for your space.

All Air conditioners remove humidity. In fact the Air conditioner was invented by accedent by Mr carrier when he was trying to invent a machine to remove humidity. He discovered that by drawing air accross a cold coil the humidity drained off the coil. He also discovered that it was a mighty effective way to cool large quantities of air, and we then had "Carrier" air conditioning systems.

When a system is to large for the area it is to cool, it will cool the air in that small area so fast that the humidity starts to condense in the room before it can be pulled through the evaprator coil.

In this case, the solution would to be either replace the unit with a smaller one.
Increase the area to be cooled. (open doors to other rooms etc). or use the dehumidifier.

How many square foot is the space you are trying to cool?
What size is the AC unit? (in "tons")
