The simple answer is no. There may be a link between air conditioning and getting a sore throat but it isn’t a causation. Air conditioning can be a breeding ground for bacteria and for infestation but with these clever ideas on how to maintain the system, it should not be an issue.
Air conditioning is one of the most necessary parts of your home that you want to keep using in the hot summer months, but what about when winter slowly approaches? What should you do to keep you air conditioning unit safe in the cold months?
Find out what to do and how to manage your unit in winter!
First things first…
Your air conditioning has served you well all summer. It’s kept you cool when the sun outside blares, so how can you take of it in winter?
The first thing to do is to cut the power going into the unit. There should be the power circuit close to the unit, so open and flip the switch from on to off. Doing this will prevent the unit from turn on in a somewhat warm winters day, so water can’t flow into the unit and potentially freeze it!
Keeping it fresh…
Just like all things, your air conditioning unit is bound to get dirty in the months it’s being used. The days of hot weather bring out all kind of bugs and dirt, so be sure to give it a good clean when you’re heading into the winter months! You can use a hose to do this part, removing bird droppings, bugs, dust and dirt from inside your unit. You should have an access panel to the inside of the air con, so be sure to remove any leaves and other debris that could potentially block up your system.
Did you know that you can actually keep your unit warm in the cold! Covering any exposed pipes with foam covers can protect them against the potentially freezing temperatures! You can use duct tape to keep them covers in place.
Check it regularly…
Remember to give you air conditioning unit the once over on occasion, just to make sure that any covers you’ve placed over the unit are still secure. This will keep snow, ice and other debris off your unit, making it ready for reuse when needed!

What health benefits can air conditioning give to your employees?
As a business owner and employer, it’s your responsibility to provide a clean, comfortable (and most importantly) health environment for your employees to work. Having ineffective air conditioning in your office can cause illness in your employees simply by the chemicals and germs getting circulated around the office.
All of these are avoidable by simply installing or upgrading your existing office air conditioning unit. Doing this could improve the health of your workforce, which will results in fewer sick days, happier staff and potential increase productivity in employees.
When a person feels too hot or too cold, their body uses energy trying to regulate their temperature. This takes energy away from other tasks, such as cognitive functions. If the office air conditioning is too hot or too cold, employees don’t function at optimal capacity and are at greater risk of developing colds, flu, headaches, allergies and other health problems.
When someone feels either too hot or too cold, their body uses up energy in order to regulate the overall temperature of their body. This energy is taken away from other parts of the body, so the person is left feeling tired from the extra energy burn. Given that the air conditioning in the office is too hot or cold, employees won’t function at an optimal level. This increases the amount of risk of employees developing the following:
As well as boosting employee health, a good air conditioning system has a number of benefits:
Office air conditioning regulates the temperature so it’s at a comfortable level. Employees in the office will no longer need to wrap up in summer and sweat in the wintertime.
In environments that use pollutants such as chemicals, office air conditioning units can actually remove the harmful air particles, boosting employee health.
An increase in productivity and a decrease in sick days means happier employees as they benefit from healthier, cleaner air.
Air conditioning in the office can prevent the spread of germs and bugs, resulting in boosts for your employees.
Air conditioning is installed thousands, if not millions, times a year, but when’s the best time to get it installed?
A question we always seem to encounter from those who are curious about installing air conditioning: What’s the best time of year to install air conditioning? Weirdly, the best time of year to get your home kitted out with A/C is winter! You’re more likely to get a better price on your air conditioner in the cold weather, as the slower season means that contractors have a lot of time to install in-between their repair service.
The Basics of Air Conditioning
What’s the basic of air conditioning? The meaning for air conditioning is simply what is sounds like: conditioned air. This means that the air has been cooled down and cooled down air has a lot of its humidity removed. The lower levels of humidity in conditioned air supply our bodies with the ability of perspiration much more effectively, which in turn allows us to cool down faster and more effectively. Many people believe that air conditioners actually produce cold air, when in fact they actually remove the heat from the air and push it to another place. In air conditioning units, an evaporator coil is responsible for removing any heat found in the air. When air flows through it, the heat is released elsewhere by a coil that condenses the air. In some split systems, the condensing coil is located on the exterior of the home, which allows for the dispossession of hot air more effectively.
Cooling your home
Having central air conditioning installed in your home may give a major benefit to your home cooling system. With the weather currently heating up and causing problems for people across Britain, so having a central cooling system in your home is vital. Central air conditioners are often more economical compared to having multiple units throughout your home, as having a unit work from one central position is way more energy efficient. Also, it eliminates the task of having to remove window units in the colder seasons. If your home is lucky enough to already have a central air heating system, having the remainder of the system installed is an easy job – as most of the air unit is already in place. If your home has a radiant or baseboard system, then you will need a higher level of A/C installation.
What are the costs of air conditioning?
Simply put, the price of air conditioning will change depending on who fits it and offers the service. The fitting of an older home can actually be a difficult task. If you’re not interested in taking out a central air system, you may consider the possibility of installing a number of fixed wall units which can reside in various rooms throughout the house. The wall units in question actually work a lot like window units, yet the need to install and remove these each season is eliminated, which makes this form of air conditioning a much more efficient service.
You should remember that you can change the design of your project in order to match the needs of your home, as this may also lead to more cost effective forms of air conditioning. Another good alternative to air conditioning are ceiling fans, as they are way more cost effective. Homes that are super insulated encounter lower levels of cooling requirements, so keep this in mind if your home is such a build.
If your home is one that lacks a central forced air heating system, A/C can still be installed, it is just going to entail more work and expense. These costs will vary by the configuration of your home. Single story homes can be readily equipped from the attic, basement or crawlspace if present. Multi-story homes may need more complex ductwork to span the different levels or have redundant systems installed to be served from multiple areas. Obviously the more intrusive the work the greater the cost. The backs of closets often provide a “chase” that is used for running ductwork from a basement to a second floor. A large portion of the expense of these installations comes from new air-handling systems that are already present in existing forced air-heating systems.
Given that your home is lacking a central air heating system, air conditioning can be installed, it’s just necessary that more work and higher expenses will have to be taken. The costs on how much this will take depends on the configuration of how your home has its layout. Homes that have one story can have an A/C unit installed through the loft or basement, given one is present. Given that the home has two stories, a much more difficult system is required for install. The more intrusive the work needs to be on your home, the greater the cost. A large portion of these expenses will come from the installation process that gives your home a whole new world in the form of air conditioning.

Air Conditioning: A History
Willis Haviland Carrier was the brains behind the modern concept of air conditioning but before his invention became a reality, many came forward with the idea of a machine that served the purpose of cooling, though changes in the design were tinkered differently to Carrier’s design. So we can mark the anniversary of Carrier’s fantastic invention, we’re going to take a brief look back at the long story – and history – of air conditioning.
1758: Benjamin Franklin and Cambridge University professor John Hadley discovered that the evaporation of alcohol and other liquids evaporate faster than water and in turn they can cool down an object enough to freeze the water.
1820: It was a case of dé ja vu for inventor Michael Faraday who made the same discovery as Franklin and Hadley some 62 years later in England. This was achieved through the compression and liquidity of ammonia.
1830s: Dr. John Gorrie makes a huge breakthrough in the case of air conditioning but it comes to no avail. Whilst working at a Florida hospital, Dr. Gorrie created an ice-making machine that uses the compression to make buckets of ice, then blowing air over them. He patented the idea in 1851, with the dream of cooling buildings throughout the world. Lack in financial backing was to blame for the failure of his invention and the world would have to wait much, much longer for A/C.
1881: President James Garfield is shot by an assassin on July 2 in 1881, so naval engineers built a makeshift cooling unit in order to keep him cool and comfortable simultaneously. The device is a simple design, with water-soaked cloth filling the inside whilst a fan blows hot air overhead, keeping cool air much closer to the ground. The good news behind the project is that the device can achieve lower room temperatures of up to 20F, but unfortunately President Garfield still dies. Oh and the machine used a massive half-million pounds of ice in just TWO months.
1902: Willis Carrier invented the ‘Apparatus for Treating Air’ at a time where he was working for the Sackett-Wilhelms Litographing and Publishing company in New York. The machine is designed to blow air over cold coils, which can control both room temperature and humidity. The device keeps paper from wrinkling as well as aligning the ink where it’s supposed to be. After discovering that other factories want to use the cooling technology, Carrier establishes the Carrier Air Conditioning Company of America.
1906: Stuart Cramer creates a ventilating device that gives the ability to add water vapour to the air in textile factories. The humidity makes yarn easier to spin and reduces the chance of breakages. Cramer is the first person to call this process “air conditioning.”
1914: Air conditioning came to the home for the first time in history. The unit is installed in Minneapolis, inside the mansion of Charles Gates. The air conditioning unit is approximately 7 feet high, 6 feet wide and 20 feet long. It’s a great possibility that the unit went unused because no one actually ever lived inside the house.
1931: H.H. Schultz and J.Q. Sherman are responsible for inventing an individual room air conditioner which sits on your window ledge. This design is common place in apartment buildings ever since. The units are available for purchase and are purchased by those who are least likely to experience a hectic, sweaty life – the rich. A large cooling system would cost between $10,000-$50,000, which is equivalent to $120,000 to $600,000 in today’s money!
1939: Packard invents the first air-conditioned car, which allows a relaxing ride for those inside. Dashboard controls for the onboard A/C would come later. For now, given the passenger would get chilly, the driver would have to stop the engine, open the hood and disconnect a compressor belt.
1942: The US builds its first power plant, named a “summer peaking” plant. It’s built to handle the ever growing electrical load that air conditioning demands.
1950s: After World War II, the economic boom finally happens as residential air conditioning becomes available to many. Over 1 million units are sold in 1953 alone.
1970s: The window units of air conditioning lose points as central air comes along. The units consist of a three main components: condenser, coils and a fan. Air gets drawn in, passed over the coils and then blasted through the ventilation system.
So, what do you think of our look into the history of air conditioning? Tell us in the comments below!
Unlike the common furnace, an air conditioner is a system of great complexity, something which is built on a number of mechanical conditions that must function in order for it to work correctly. Each mechanism is sized to meet a specific size in order to fit the “load” when the build commences. Both the amount of air flow across the internal coils and the amount of refrigerant are both huge factors in the system, and when either one of these fails to work properly, the whole system will begin to develop problems.
If, for a whole host of reason, the indoor heating in your home is at a high level due to the amount of people who occupy the space, the appliances that produce a lot of heat through the use of electricity or simply because of changes in the home, your air conditioning unit may start to falter as it struggles to keep up with the higher levels of demand from your home environment.
Given that the refrigerant charge of the system leaks, which it can, the capacity of the system could potentially begin to lower, depending on how much of this escapes in the process. Given this process happens, the cooling system will actually produce warmer air compared to the cold, so it won’t be able to keep up with the air when it gets hotter.
If the airflow amount across the outdoor coil is reduced, the ability to reject heat to the outdoor environment is reduced, again furthering the chance that the capacity of the system may be reduced, especially when the outdoor temperatures are high.
In dry climates, the same issues can occur when the indoor coil reduces as naturally, higher airflow will help the unit whilst lower airflow hurts the health of the air conditioning. In humid climates, the situation can become more complex as the hot air directly effects the performance of the unit. At higher airflows, there are less amounts of dehumidification, leading to high indoor humidities. If the airflow gets too low, however, the evaporator coil may freeze, which effectively breaks down the unit.
