As the temperature rises during the summer season, many households turn to more than just ice-cold drinks to keep them cool. Air conditioning was once regarded as a residential luxury, but has become something of a necessity throughout the United States. Not only will air conditioning cool a room to a bearable temperature during balmy, humid summer days, but also uses the same techniques as a refrigerator to provide ventilation and dehumidification for indoor air.
Brief Air Conditioning History
The concept of cooling spaces by using natural elements is one that can be traced to the times of ancient Egyptians, who circulated aqueduct water through the walls of various structures to produce a cooling effect. Even in those times, since water was scarce, wealthy residents were only able to enjoy this luxury. During hot weather, medieval Persians created wind towers to cool down buildings. It wasn’t until the early 1800s that a British scientist started to experiment with the compressing and liquefying of ammonia. He learned that liquefied ammonia could chill the air when it evaporated.
In 1842, an American doctor named John Gorrie created ice to cool the air of hospital patients and had dreams of using this technology to create a cooling machine for buildings. He tinkered with the plans of constructing an ice-making machine with the help of a financial backer. When his support was no longer available, he could no longer finance his experiments. When he passed away in 1855, the idea of air conditioning was also laid to rest for about 50 years.
After the attempts of Gorrie, industrial air conditioning was created in the early 1900s with the first modern electrical version of air conditioning. Throughout the years, a shift was seen in the use of air conditioning, as automobiles and households began to benefit from the invention. The Carrier Air Conditioning Company began to lead the way in bringing the concept to the public, and during the 1950s, it was a contagious residential dream.
The Pros and Cons
The benefit of enjoying a cooler atmosphere during heated weather is not the only advantage gained when turning on the air conditioner. A household, vehicle, and other building environment becomes cleaner and safer for breathing when air conditioning is able to prevent the growth and spread of harmful microorganisms. Individuals who suffer from allergies and asthma are especially thankful for the better atmosphere an air-conditioned room provides, as less dust and dander are present. In seriously hot weather, babies and the elderly also benefit from air conditioning as heat waves have been known to take the lives of those whose immune systems and health might not be the strongest.
One of the most controversial topics attached to the subject of air conditioning deals with some of the materials that are used to produce the cooling affect of these machines. Fluorocarbon refrigerants also contribute to global warming concerns, which serves as one of the main ways that air-conditioning impacts the state of the environmental world. Fluorocarbon refrigerants also add to the problems concerning ozone layer depletion.
While the temporary relief that air conditioning provides makes hot summer nights and heat waves a more bearable event, many question how much the world will pay in the long run after the environmental damage has settled. Today, scientists are working on making more environmental friendly products, but for now, individuals are reluctant to part with their instant cool during the thick of summer.

Solving air flow problems in your home
Basic things that the homeowner can check to help air flow:
First and foremost, check your furnace filter to see if it is dirty and if so, remove the dirty filter and install a new furnace filter. Plugged furnace filters restrict air flow by creating a pressure drop. Next, walk around your house to see if any cold air returns have anything such as couches, rugs or cabinets obstructing the vent. If anything is obstructing the vent, then remove these obstructions so that the cold air return, which is an air intake, can draw in enough air. Last, but not least, walk around your home to check to see if all supply registers (heat vents that blows out air) are open. All supply registers should be open. A popular homeowner misnomar, is that by shutting off certain vents throughout the house will cause other vents to blow harder. This simply is not true, because CFM (a measurement of air flow, cubic feet per minute) is determined by the pipes diameter and only so much CFM can ever blow out due to the size of the round, regardless if other registers are shut off or not. Shutting down too many supply registers usually causes more harm than good by creating pressurization problems with the overall duct system, that in an extreme case can actually cause your furnace to short cycle on a high limit and hence increases the cost on your utility bill while working key HVAC components and parts to reduce their life expectancy. Never buy and install heat vent filters either, because these filters really cause pressurization problems too. If there is too much dust blowing out of the vents, then the best thing that you may consider is to have the HVAC system cleaned out thoroughly with the power vacuum/air sweep method in air duct cleaning by an ACCA (Air Conditioning Contractors of America) member company. An average price for a 1 furnace home would cost between $400.00-$700.00 to do the job correctly, depending on where you live in the country and depending on the service providers cost to operate.
Some solutions that an HVAC company or contractor may suggest:
Very often in older homes, air ducts are sized incorrectly due to building departments in the past not emphasizing the importance of properly sized air duct construction and the by the fact that the builder wanted to save a buck to construct his own ductwork rather than paying a heating and cooling professional to install the ductwork properly. In recent years, many building departments throughout the United States really have zeroed in on enforcing proper duct design, so in most newer homes indoor thermal comfort has improved drastically. Some of the things that your licensed HVAC company or contractor may suggest to you to drastically help your older homes air flow is as follows:
- Let me tear out all of your ducts and start over! (That would be sweet, however in many instances that is just not practical due to cost, time and a big mess!)
- I can bandaide your homes HVAC system by replacing your old inefficient furnace with a Rheem 80% AFUE 2 stage variable speed furnace equipped with the GE ECM motor. Visit www.luckyduct.net to learn more about the GE ECM motor. The GE ECM motor operates 30-40% more efficiently than a standard conventional multi-speed motor and sustains constant CFM even if your ductwork is undersized and restrictive. What this means is that vents that seem to never blow air with your inefficient old furnace will all of a sudden blow air after the new Rheem furnace equipped with the GE ECM motor is installed. The ECM motor also allows homeowners to qualify for a $50.00 EPACT tax credit that you can receive when you do your taxes, so even the Federal government wants you to go for it!
- For some reason your home does not have enough return air openings to even allow enough air to enter the duct system at all! We need to build additional return air openings into your ductwork so that we can get additional CFM into the HVAC system so that your AC indoor evaporator coil can stop freezing. Good golly, you’re paying more money on cooling not to mention the fact that your AC doesn’t even keep your house cold enough! Let’s fix that and add some new return air openings so that you can save some money on your utility bill and actually cool down this summer too!
- Let’s go ahead and rip out the 4″ diameter supply runs and install 6″ diameter runs so that we can circulate more air into that sun room!
- You know, your ducts amazingly enough are sized correctly, but all of the air is escaping into unfinished portions of the house because the construction of the ductwork is very loose. Let’s go ahead and seal up every trunk line connection, brace, joyce and end cap with mastic duct sealant. By sealing up every duct connection on the entire system we’ll see if we can blow those curtains side ways afterall! No, just kidding, but the air will come out a touch harder, though as a result in sealing up the ductwork better and you will see a significant reduction in your utility bill because the system will only cycle half as often now.
- You know, for some reason all of your ductwork is sized correctly, but the return leg that is attached to your furnace is severly undersized and is acting like a choke point. Lets rip this leg out and install a bigger one with a greater dimension!
- You know, your homebuilder really got cheap and should have installed 2 seperate systems considering that your home is 3600 Sq/ft. Two smaller systems will actually cost you less on the utility bill to operate and will provide greater comfort. Save up some money and lets build that second system in the attic!
- You know, the most cost effective thing that I can think of that will improve your indoor comfort tremendously is to simply just zone your current system so that 3 different thermostats will control 3 different temperatures in your home. Aprilaire and Honeywell make great zoning systems and we usually can get this system installed from $3800.00-$6,000.00 depending on how fancy of a system you want to have installed!
You see some of these bandaide jobs will cost just a few hundred dollars, while some solutions may cost a few thousand dollars, but in the end after the corrections are made, your utility bill will probably reduce a bunch and you’ll finally have true indoor comfort that you didn’t have before. Many HVAC companies and or contractors will give you more than one option to consider as well so that no matter what you decide on some sort of indoor air comfort solution will be achieved to atleast improve the comfort situation. The best thing that you can do as a homeowner is to select an ACCA member heating and Air Conditioning company or contractor to ensure that your comfort specialist has all of the latest and greatest training, tools and professional assistance to best serve you as a customer. In the long term you won’t regret it because you will save some money on the utility bill and you will be much more comfortable in your home as a result.

As the summer starts its wet climb up the thermostat, residents should relieve themselves by turning on their air conditioner Chambersburg PA heat doesn’t give up. Air conditioners are a major comfort in modern life, and a trustworthy retailer will help you to find a quality air conditioner to keep you cool thru the summer months.
An air conditioner definetly would have helped onetime Chambersburg, PA resident John Brown when he hid away in Mary Ritner’s attic in the summertime of 1859. The militant abolitionist couldn’t have been too cushty when he settled up in the attic in June of that year. His face would have been lined with sweat in that cramped, humid area. If only the Ritners had had the modern miracle of an air conditioner Chambersburg PA could have bettered his plans for the unsuccessful raid on Harper’s Ferry. With an effective air conditioner, who is able to say what would have happened?
Chambersburg, PA’s insufferable summers also played a role in the Civil War. During the June 1863 Gettysburg campaign, the Virginia Cavalry made use of the heat to accelerate their burning of many Chambersburg warehouses. Robert E. Lee subsequently established his headquarters in Chambersburg, where the oppressive heat could have been the maximum amount of an enemy as the northerly army. The heat accelerated another fire the following summer, when Confederate troops burned down the majority of Chambersburg. Chambersburg was the site of many major battles in this Civil War, but there is no need for you to battle the heat so violently this summer. A quality air conditioner will make sure that the summer heat incurs no casualties in Chambersburg, PA this summer.
There are several different purposes for air conditioner Chambersburg PA, but they all have the same goal : keeping humidity low, circulating air, improving air quality, and temperature control. The comfort application of air conditioners guarantees that indoor air temperature will remain consistently low and tolerable to inhabitants of the crib or business regardless of the outside weather. The process application of air conditioning can also provide comfort, but the processes performed are the determinant of the temperature rather than human preference. An example of the process application of Air Conditioning is in nuclear facilities, where the difference of a couple degrees can be key to the soundness of these dangerous properties.
Air conditioning is an essential part of present-day life and something no Chambersburg, PA resident should be without. Your home or business should be outfitted with a quality air conditioner. Thru the use of their air conditioner Chambersburg PA residents do not have to dread June, July, and Aug. Air conditioners let you decide your comfort level, not the whims of mother nature. Keep yourself free of sweat and unhappiness by buying and maintaining a quality air conditioner today.

What is a ducted Air Conditioning installation?
A ducted air conditioning system basically means your air conditioner or heat pump is hidden away in your roof space, or under your floor. Ducting carries air from your home to the air conditioner and is then heated or cooled to keep your indoor air temperature constant. One central unit can serve most houses.
Air vents are cut into your ceiling or floor, which are then connected to the air conditioner via the ducting. This enables one air conditioner to serve your whole home.
Air conditioning for multi-storey homes
If your home is on two or more levels, it is still possible to have ducted air conditioning installed. You have the option of going for two or more smaller units, or having duct risers installed.
A duct riser is a vertical duct that connects two levels. This allows you to then transfer air from the air conditioner in the roof space to a downstairs level through a duct hidden away in a cupboard or boarded in with a false wall.
The benefits of air conditioning
Air conditioning has many benefits. If you live in a hot and humid climate, it can provide cooling and dehumidification. In colder climates, air conditioning can provide you with very energy efficient heating for your home.
As well as keeping your home at a constant temperature, excess moisture is removed from the air by the dehumidify mode, and dust particles and allergens are removed from the air by the use of advanced air filters.
For asthma sufferers, air conditioning or a heat pump can be of great benefit. Reducing the relative humidity level inside your home and filtering out dust particles can make it easier to breathe and much more comfortable.
How air conditioning works
At the heart of most air conditioning installations is a heat pump. A heat pump, according to the dictionary, is a mechanical device for moving heat energy. What this means is that instead of converting electricity into heat energy directly (like an electric bar heater for example), the electricity is used to move heat energy. Heat energy is transferred to or from the air in your room by use of refrigerants inside the heat pump.
In summer, excess heat energy is transferred from the air indoors to the air outdoors. This has the effect of cooling your room down. As the air is chilled below dew point, excess moisture is removed from the air as well (dehumidification).
In winter, heat energy is transferred from the outside air to the indoor air (the complete opposite of the summer example). By simply transfering or moving heat energy into your room by this method, you can gain up to 4kW of heat energy from each 1kW of electricity that is consumed. Compared to other forms of heating, a heat pump is the most energy efficient way of heating your home.
More information
For more information on ducted air conditioning, please contact a local air conditioning company. They will be able to advise you on the correct sized air conditioner and ducting installation suitable for your home. Always seek professional advice.

My 1993 Chevy G10 Van has no air and I use it for work. What is the best way to add Air Conditioning? Ideally I would like a portable cigarette lighter powered one that I can also use in my car, but I haven’t found one that is powerful enough or doesn’t require a ‘cooler evaporator’. RV units usually take too much juice. What aftermarket units are available and how can I get by inexpensively?
look for another van with AC it’ll be a lot easier

Many drivers have experienced odors stemming from Air Conditioning in the past. Think about the first time that you turn the air conditioning on in the vehicle, that first hot day - we can avoid the strange smells that arise from the vehicle with proper air conditioner maintenance, installation and flushing of the fluids that are used within the air conditioner.
What causes these foul smells to arise from the air conditioner systems? Sometimes, the solution can be as simple as flushing the air conditioning system, as running the vehicle in a dusty, dirty or sandy environment could mean that these particles have been absorbed into the system, meaning that the vehicle is than transferring this dirty air through the vehicle lines and systems causing odors to be present within the air conditioning system of the vehicle.
How does the air conditioner work? When the vehicle air conditioning is turned on, the compressor for the air conditioner transforms the liquid, the refrigerant in the radiator where it is transformed to a liquid, which has the ability to cool the engine. There is a unit that allows for the evaporation of heat, and allows the cool air to flow through the air conditioner, cooling the vehicle and making for a more comfortable drive.
Did you know that the majority of smells that come about from an air conditioning unit in a vehicle are moldy or mildew smelling odors? The particles within the air conditioning system, the dirt and grime within, can lead to mould developing. This doesn’t only produce a bad odor, but can be harmful to your health when breathed in over long periods of time. This dirt can accumulate within the housing of the air conditioner, and bring the odor out each time that the air conditioner is turned on.
Each season, experts recommend that the air conditioning system be flushed, and new fluids be injected into the system. Did you know that just maintaining this one simple task can reduce the amount of smells coming out of the air conditioner significantly? As well, this gets rid of the excess dirt, mould and other bad things that make their home in the housing of the air conditioning system. This maintenance for the system can be completed for about a hundred dollars at the local oil changing shop, or the local mechanic.
Ensuring that these simple techniques have been completed will make your air conditioner run more efficiently, while getting rid of the bad smells that come with dirty air conditioning systems.
As an alternative to these methods, the air conditioner housing can be removed and the system can be cleaned. Cleaning the housing, as well as cleaning the hoses and pipes that come with the system means that air can run through a clean system, which will ensure that the air that comes through the vents within the car is clean, and can cool efficiently with a fresh and clean smell that comes with a proper functioning air conditioner.

In order to stop night sweats naturally you should learn about the mechanics of sweating. There is no reason why you should suffer from night sweats ever again. Once you understand how sweating evolves, you will have the knowledge to make night sweats stop.
Your Body Uses The Following Methods To Keep Itself Cool:
* Radiation (radiant energy)
* Conduction (conductive heat transfer)
* Convection (conveyance of heat)
* Sweating (we are trying to avoid this)
Our body cools itself by four main methods. The first method is radiation. Radiation is like the heat that you feel while standing in front of an oven that is on.
The second method is conduction. Conduction is the heat that you feel if you touch the oven while it is on. The third method is called convection. Convection is heat that is picked-up by the air that passes by the oven while it is on.
Simply put, convection is heat that is conveyed to the air surrounding the hot object. The forth and final method of cooling is evaporation, better known as sweating.
Typically body cooling takes place in that very order. If the body will not cool itself via radiation, conduction, or convection, you will start to sweat.
The Temperature Pendulum
The objective here is to teach you how keep your body cool and keep from sweating at night. To fully understand how to manage night sweats you must understand each method of cooling your body in order to fully evaluate your options.
One thing you should make note of is that your body will normally maintain a relatively constant temperature throughout the night. The problem occurs when your body is not keeping a constant temperature during the day or night.
People that suffer from night sweats understand the concept of varying body temperature. Therefore you will look at the cooling cycle with that in mind.
A Balancing Act
The temperature balancing act starts when you get in bed at night. You feel the cool of the sheets and the comfort of the bed. This is a good example of conductive heat transfer. Whenever there is a difference in temperature between the object you are touching and your body, you will feel either a warming sensation or a cooling sensation.
Remember that heat travels from hot objects to cooler objects. So if you touch ice you feel cold because the heat is leaving your body and going into the ice.
If you touch something that is warmer than your body you feel warmer because heat is moving from the hot object into your body. That is conductive heat transfer.
Now what happens when you are next to an object long enough to equalize the temperatures? Let’s go back to the bed scenario. When you get in bed it feels cool. Right away your bed starts to absorb the heat your body is generating.
The problem arises when the material that is absorbing your body heat is no longer able to absorb more heat. At that point your body starts to look for other methods of cooling.
In Your Bed
Heat transference by radiation will be absorbed by your bed. Radiant energy will be absorbed by the bed material until you reach a point at which the bed can no longer absorb more radiant heat.
Conductive heat transference, which is the heat that is transferred when you touch something, will be absorbed into your bed as well. This heat will also accumulate until your bed can no longer absorb any more.
Convection, which is the transference of heat by conveying that heat, in this case to air, is only effective when you can generate air movement within that space. Heat will transfer from your body to the air around you and then move off, either by a buoyancy difference or by induced movement.
What this means is that when air gets warmer it tends to rise and be replaced by cooler air. If the air is induced to move, like standing in a breezeway or next to a fan, hot air will move off giving fresh cooler air an opportunity to absorb more heat.
Being that you are in a bed, covered with sheets, and the air surrounding you is trapped, the fresh air required for convection to work properly, is not there.
But if that was case wouldn’t everyone sweat in bed? The short answer is no.
Equilibrium
There is a point where you reach equilibrium between heat absorption of your bed and heat generation of your body. This is the point where your bed is able to absorb enough heat to keep you comfortable. This is your comfort zone.
Let’s say your body generates 200 units of heat every minute. Now equilibrium is where the bed is able to absorb 200 units of heat each minute. At that point you can sleep comfortably; you are in an equalized state.
Now let’s say your bed is absorbing 250 units of heat every minute, but you are only generating 200 units of heat each minute. In this situation you will have a cold bed. This is not equilibrium.
If your bed can only absorb 150 units of heat each minute and you are generating 200 units of heat, then you have a hot bed. This again is not equilibrium.
Those Hot Bodies
If you are suffering from night sweats, your body is generating heat at different levels during the night. Although you are able to get into bed and it feels nice and cool, that feeling fast evades you. For those of us that have night sweats, we are dealing with a body that generates heat at varying temperatures all night long.
As with the previous mentioned equalized bed scenario, when you first get into bed your body is generating 200 units of heat each minute. Your bed is absorbing 200 units of heat each minute. You are in equilibrium, all is well. But then your body temperature rises.
Now your body is generating more than 200 units of heat each minute and your bed can’t keep up. If you are generating 250 units of heat each minute and the bed can only absorb 200 units of heat, where will those extra 50 units of heat go? They will go nowhere. They start to accumulate and buildup between the sheets.
This buildup of extra heat starts a downhill roll right to sweating. Once the extra heat starts to accumulate, and your body starts to get warmer, the only method left for cooling your body is sweating.
Turning Off The Oven
So the question is how do you solve the problem of excessive heat that leads to sweating. In order to do this you must look at the three main methods of cooling and see what you can work with to keep your body cool.
Radiation is the first method used by your body to eliminate heat. Yet that heat is much like heat transferred by conduction. It is absorbed into the bed and will contribute to night sweats. This heat must be drawn out of your bed.
Conduction is the second method of cooling your body. The only way to utilize this is to make the bed much cooler. Conduction is the method that doctors are prescribing when they tell you to keep your room cooler.
Keeping your room cooler will help your bed absorb more radiant heat and conductive heat but relying on conduction can be cumbersome. The cost associated with hyper cooling a room and the effect extra coolness has on other members of the house are just two reasons to look else ware.
Remember the bed that absorbs 250 units of heat is a cold bed when you are only generating 200 units of heat.
The third method of keeping you body cool is to utilize convection. But convection requires air movement to be effective. So how do you move air when you are between the sheets?
There are several things you can do move the air between your sheets. One is to kick off the covers and let some cool air in. The other is to raise the sheets and allow some air to flow in. When you lower the sheets the hot air flows out, The other option is to use a fan made specifically for this situation.
Keeping Your Cool
With all the methods stated above you will find that moving air between your sheets and around your body is actually a simple, cost effective way to keep your body and your bed, cool.
A special fan that can generate a light breeze between your sheets will be more effective then lowering your thermostat by six to eight degrees. This type of cooling system will also benefit you in the following ways.
* Much lower cost of cooling then Air Conditioning.
* Variable speed under your pillow
* Can be directed at a single user
* Evacuates stagnant, humid air trapped between your sheets
* Keeps you and your bed at a constant temperature
A system like this will generate a light breeze that will travel between your sheets along your body and push the hot air out of your bed. It will also eliminate the heat that has been building-up within your bed.
Any conductive heat or radiant heat that has built-up in your bed will be eliminated with the breeze. Neither your body nor your bed will accumulate that extra that typically awakens you at night. .
The extra body heat that you generate during the night, will be quickly moved out from between your sheets. This simple breeze will keep your body from ever reaching the point at which it starts to sweat. This is the most effective method of dealing with night sweats when you look at it from a thermal dynamics point of view.
There are other methods of dealing with the effects of night sweats, like wicking pajamas and absorbent sheets, but those are not dealing with the problem at hand. They are only dealing with the aftermath of the problem. They are collecting sweat. What you want to do is keep from sweating all together.

Santa Fe homes have some of the nation’s most advanced cooling systems, thanks to the region’s hot, dry summers. Central Air Conditioning is common here, but homeowners and builders who want to reduce electricity costs and environmental impact have turned to other cooling methods to get the most bang for their buck. One of the most popular and efficient home cooling systems in the Santa Fe region is evaporative cooling, a combination of ancient techniques and the latest in air flow engineering. Homes in Santa Fe use a variety of different types of evaporative cooling methods to keep their home comfortable all summer, and reduce air dryness in the winter heating seasons.
Evaporative coolers employ the simple principle of air humidity to reduce overall home temperature. They are typically comprised of a metal or plastic box on the outside of the house, with vented sides for air intake, a centrifugal fan or “blower,” an electric motor with pulleys, and a water pump to wet the evaporative cooling pads. In cooling homes, they simply draw air through the vents, which pass through the damp pads and out into the rest of the home. Because they draw air from outside the building, evaporative coolers must be accompanied by vents to allow air to move from inside to outside. The venting system allows for 15 or more air changes per hour within a home, which dramatically reduces air age.
Common evaporative cooling methods include direct evaporative cooling, indirect evaporative cooling, and two stage evaporative cooling. Direct evaporative cooling is the same as described above, with an air intake sucking moistened air inside, pushing it through the building, and later venting it outside the building. Indirect systems work by the same process, except without air passing freely through the building. They contain the cooled air as it passed through the building in some type of heat exchanger, thus making the building cooler without increasing the humidity. Two-stage evaporative cooling pre-cools the air in a heat exchanger before sending it through the wet cooling pads. This results in less humidity throughout the building, because cooler air doesn’t hold as much moisture as untreated warm air.
Another advantage of evaporative coolers is their cheaper installation cost - they usually cost one quarter to an eighth as much as much as air conditioners to install, and require much less energy to operate. Many Santa Fe real estate buyers and sellers have saved a lot of money by learning the basics of evaporative cooling.

It is a 2009 Renault Megane Coupe.The Air Conditioning comes on automatically upon starting and remains on until the car has heated up. This appears to increase the fuel consumption, so I always turn it off.
I would rather if it didn’t come on in the first place.
Check to see on what setting the air direction control is set to, normally if you have it set to windscreen de-misting then the air-con will come on.
Ja.
