Central Air Conditioning or Window Air Conditioner


Many people look into installing air conditioning in their home every year. There are many options to consider when it comes time to make that decision. To help make that decision more clear, I will explore some of the positives and negatives of the two major options. Ductless Split A/C type units lately are also becoming more of a popular option. I will do another “Tips and Tricks” on that option. To include that in this one would just be more confusing. So for now we will just look at window air conditioners and central air conditioning.

Central air conditioning is usually the best way to go if you already have a central hot air heating system already installed in your house or building. The advantage that you have is that you already have the air handler or blower part already installed. The ductwork for the distribution of the air is also all ready in place. The ductwork may need some modification to make it work well for air conditioning, but the major part of it should be adequate. To use the existing furnace and ductwork an A/C coil will need to be installed at the furnace. An outdoor condenser unit will be installed outside and copper tubing will be used to connect the coil to the outdoor unit. Some electrical wiring will need to be done to power the outdoor unit. Low voltage wiring will also be needed to hookup the thermostat, the furnace, and the outdoor unit together so that they can talk to each other. Basically the thermostat will just tell the furnace to run the blower on high speed and the outdoor condenser to start up.
If there is no central hot air heating, then the installation of central air conditioning can be much more difficult. Many homes that do not have hot air heat also do not have the room to install ductwork. This would eliminate this possibility. If you are in this category you should get a professional to look at your situation to see if central air conditioning can be done. If it is the room available is to enough to do a good job and get large enough ductwork installed, then do not force the issue and go another option. Ductless split type air conditioning may be your best option.

A window air conditioner in my opinion is a last resort for air conditioning your house or building. There are many down sides to window air conditioning units. There are two good things that window air conditioners have going for them. They are very inexpensive when it comes to cost per BTU of cooling. They also install very quickly and easily. That is where the good part of them ends.

Window air conditioners are security risks. If a thief wants to get into your house, the thin sheet metal box that holds the unit in the window can easily be pulled apart to get in through the window. I have seen many units that are not even screwed fast. If the window air conditioner is just there, balancing in the window frame, it becomes very inviting for a unexpected guest. The window air conditioner is also very inefficient. These units use more power per BTU of cooling than any other type of air conditioner. If you are a light sleeper, than chances are you will not want one of these window shakers. Window air conditioners are one of the loudest forms of air conditioning.

The fan for these units is very loud when running. Then add the noise of the compressor and you have enough decibels to keep many people wide awake all night long. If you choose to use a window air conditioner, than you should also look for a place that it can be secured and placed in a room that you will not be sleeping in.


As you can tell by now, I am not a big fan of window air conditioners. They do have a place for some people. However, you do need to be aware of the problems that you may encounter with them. The low initial cost can be offset by the fact that they typically do not last as long as a central air conditioner.

Central air conditioning will last much longer, be quieter during operation, be more efficient, be more secure, but the initial cost will be higher. How much depends on each situation. When considering your options for air conditioning installation you need to get prices for everything and then decide what type of unit will work the best for you.

Portable Air Conditioning great portable air cooling


Portable air conditioning offers you the convenience of mobility. All you have to do is roll the portable air conditioner to the room in which it's needed. Install an exhaust hose out a window or other opening (everything you need is provided) and turn it on. The installation process for these units is very simple. These portable air conditioning units are built small enough to be very mobile and are supplied with wheels for easy movement. A portable air conditioner will also work very well in apartment situations where you will often find a window unit is unacceptable.

Portable air conditioners are very unique in that they are portable and can be easily moved to different locations in your home or business. They can be a highly effective way to either help out an existing HVAC system in one room or cool a single room entirely. They are also one of the best ways to cool a room or area without having to install a window mounted unit.

These air conditioners use a compressor and Freon to cool just like normal air conditioning. They are very effective in cooling rooms and to keep the humidity low. Like normal air conditioners portable units extract hot air that must be vented. That is why they need to have the exhaust hose to the outside. These units can cool air as well as air conditioning done with window air conditioners. However they do not require installation like conventional window air conditioners this makes them very convenient for seniors or physically challenged people. Most portable air conditioners are supplied with a window kit. This kit contains exhaust hoses that will work in any window: double-hung, casement, awning or slider. Because they vent through an opening like a window they require no permanent mounting like window air conditioning.

Portable air conditioners are a very good cooling option for those who can't use the more conventional air conditioning methods. Remember though that this type of unit is not as efficient as most window units or conventional air. So while they may make your environment cooler, it won’t turn your tent into a room at the local hotel.

So as you can see these air conditioning units have some great advantages over other types of air conditioning. They are a great alternative for unique applications where central air or conventional window units are either unfeasible or too expensive. During special events, portable air conditioning can also be a great way to keep guests or equipment cool and comfortable. Always be aware though that because portable air conditioning will remove moisture from the air, they will also need to be drained occasionally similar to a dehumidifier.

Does your application warrant a permanent air conditioner of some form or should you just use a portable one? There are some interesting things to consider when making that choice. Weigh out all of the different options and make that decision based on what will best suit your needs.

My corona air conditioner inverter does not produce hot air


these are all in one units, some of them are made like smaller central units and some of these are separate ac and heat units. the heat in the separate ones is run off of a heat strip in the unit it's self the ones that are made like a central unit reverse the flow of the freon in the system to draw the heat from outside. this is not something you can repair very easily yourself. most places require because of the freon that you have a certified HVAC technician to work on them.

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.

I have central air and I was wondering how do you put freon in it because its not blowing out cool air


Is the compressor starting? On the outdoor unit you will see a large copper pipe and a small copper pipe. Is the larger of the two cold to the touch? wet? Just because a central air system is not blowing cool air does not mean it needs freon. If you have clogged filters it cannot do an air exchange. So, I would recommend checking the easiest things first before adding Freon.Most people make the mistake of adding Freon and overcharge their system. In a low load situation you can slug the compressor with liquid and your system is ruined. If you do have to add Freon it indicates that you have a leak. An AC System is a closed system and if it is working properly you should not have to add Freon.

My A/C blowing air, but it is not cool. It has started freezing up. We just replaced the air filters and since then it is freezing up. We even gently cleaned the a/c coils before replacing the filters. ...


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.

Hi have central air . Unit working ok but noticed not blowing cold air . The fan outside is working , Unit comes on . Could it be feron . unit it about 7 years old . Purchase house about 4 years ago


You need to have a pressure gauge the reads for R-22. (Freon) It sounds like the system might have a leak. Look for a wet place any place on the units pipe system. It has a little oil in with the freon that is forced out of any leak. If you see a wet place this is oil. It is also the location of your leak.

AC is not working


Sounds like the A/C system just needs to be recharged. When was the last time you had this done? Just take it in to your mechanic and he can do it for you and if that's not it for some reason, then he will be able to find the problem but most likely you need more freon added.
