What Do AC Filters Do?

What Do Those Air Conditioner Filters Do?

The job of the filter is to remove particles from the air stream to both keep the air conditioning system clean and to remove particles from the air.

Almost every air conditioning system has a filter upstream of the evaporator coil. This can be in the return grille or in special slots in the duct system and can be a fuzzy-looking or a folded paper filter.

As the filter does its job, it gets loaded with more and more particles. This is actually a good thing and makes the system more efficient, but it also increases resistance and reducing airflow. When this happens, it is time to change the filter. How long it will take to happen depends on how dirty the air is and how big the filter is.

If you don’t change the filter, air flow will decrease and the system won’t perform as well. Not only that, but if the filter is too dirty, it starts to become a source or air pollution itself.

If you take the filter out completely, you would solve the low air flow problem, but this victory would be short lived. The particles that the filter would have taken out will now build up on your evaporator coil and eventually cause it to fail. Replacing it with a new filter is a much cheaper option.

Winter Warming: Use Your AC in Winter

air-conditioning-unit-control-300x200Winter is here and keeping warm is now priority number one!

We’re going to start with the most obvious solution for keeping warm: wear an extra sweater or jacket.. And a hat! A lot of heat escapes from our heads.

Of course you can use your AC throughout the winter to control temperatures and help maintain a comfortable amount of warmth.

You may also experience a lot of humidity at a point during the winter where it collects on your windows. Turning on the AC would be an effective way to remove that water vapour. Sure you may have checked the fan to ensure its not blocked up with snow, or maybe you have a cover and simply removed it so you can fire the air conditioner back up temporarily.

The term air conditioning makes people immediately think of a system to cool you down in the heat of the summer or in hot climates. Many could not think why anyone would use winter air conditioning. What many people do not realise is that air conditioning is a term for a heating and cooling system that can be used all year round. Winter air conditioning does not mean freezing air is blasted into the home, rather that the air conditioning operates in a reverse cycle to warm the air. In fact, winter air conditioning is one of the most affordable and economical heating systems you can choose for your home or office.

Air conditioning helps by keeping the air in the home fresh and free from dust particles and other pollutants and can even help to control germs spreading. Ideal for allergy sufferers, your pets will no longer be making your guests sneeze or dabbing at their watering eyes.

All types of offices and retail spaces can benefit too. Research shows that with good quality air conditioning systems, productivity and efficiency improve. Workers also demonstrate better performance. Clearly apart from the other benefits, winter air conditioning to keep employees warm is every bit as important as keeping them cool in summer time.

5 Benefits Of Air Con For The Workplace

Professionally installed air conditioning systems have many benefits in the workplace from increasing employee productivity to improved general health. Let’s take a closer look:

1. Productivity

Studies have suggested that men and women prefer slightly different temperatures. The temperature that produces the most productivity is around 21.7 degrees to 22.2 degrees (71-72 degrees Fahrenheit). Be aware of seasonal changes and vary the temperatures accordingly.

 

2. Air Quality

Busy and bustling office spaces and workplaces are breeding grounds for coughs and colds. Air conditioned air spaces can reduce the amount of bacteria and dust particles, odours, and potential allergens as the filters purify the air.

 

3. Comfort 

Offices are often too cold and uncomfortable for employees. Maintaining the temperature is important and modern systems have the ability to respond swiftly to fluctuations in temperature. Highly sophisticated systems are able to recover heat from warmer areas of a room and redistribute to cooler areas, making them highly efficient systems.

 

 

4. Noise Pollution

As your system continually works by responding to the temperature of the atmosphere you wouldn’t be aware as the systems are almost silent. Staff will remain undisturbed and uninterrupted even when the system is working at maximum capacity.

 

5. Health

Almost half of office workers believe air conditioning spreads illness. You can keep the windows closed in an air conditioned room, making for an environment with lower pollen and lower pollution levels from the air outside. The humidity of the room will also be decreased controlling the level of mould spores in the air and any other bacteria. So overall an air conditioned workplace makes for a healthier workforce and will particularly help those who suffer from respiratory illnesses.

Heat Wave – Why Is My AC Leaking?

The British summer has finally arrived, and while it could disappear as soon as it came, things are really hotting up around here.

We’re predicted 32C today, which is going to really put your cooling systems to the test!

Over the last week we’ve had an increased number of service calls, relating to air conditioning systems which are leaking water into the client’s premises.
On the cooling side of the AC system, the evaporator coil gets very cold. The idea is that warm air is passed through the evaporator coil, thus cooling the air down..which is then blown into the area you’re working in. This process creates moisture (much like the inside of your freezer).

The moisture that is created then has to go somewhere, usually outside of the building via a gravity or pumped drainage system.

The amount of moisture created can be exasperated by a number of things:

-) The refrigerant pressure in the evaporator is too low, causing it to get colder than designed and icing up
-) The air flow across the evaporator is restricted, for example because of a dirty filter or failed fan
-) High levels of ambient humidity

Anyway, this moisture has to go somewhere!

In summary, the water leaking from your ceiling area right now could be as a result of a number of different issues related to your air conditioning unit. Examples of these issues are

-) Blocked filters
-) Blocked coils
-) Blocked drainage system

There’s a pattern emerging! Water generally does as it’s told, and runs downhill (or if pumped, uphill). Problems occur when something gets in the way and the water starts to overflow!
