Air Conditioner Maintenance

An air conditioner‘s filters, coils, and fins need regular maintenance for the unit to work effectively and efficiently throughout its lifetime. Neglecting this maintenance will lead to a slow decline in the performance of the AC Unit. 

Air Conditioner Filters

The most important air conditioner maintenance‘ task to ensure its longevity is to regularly replace or clean its filters. Blocked filters stop normal airflow and reduce the system’s efficiency. With the airflow obstructed, any air that bypasses the filter may carry dirt directly into the evaporator coil and impair the coil’s heat-absorbing capacity. Swapping out a dirty, clogged filter with a clean one will lower your air conditioner’s energy consumption by approximately 5% to 15%.

Does air conditioning cause sore throats?

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.

How to prepare your air conditioning unit for winter

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.

Insulating pipes…

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!

A Brief History behind 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.

What problems can your air conditioning face?

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.
