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.

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.

5 Common Air Conditioner Issues in Winter

Autumn leaves are now appearing and winter is quickly approaching.

Homes, offices and retail spaces all benefit from air conditioning all year round and research has proven that productivity improves with quality air conditioned spaces. Workers perform better and customers feel better as we all like to be cool in the summer and warm in the winter.

If the worst should happen and you need assistance with your AC unit, RCL are available and offer a comprehensive 24 hour call out service. We come out and instruct our clients how to use your system and ensure the air-conditioning is balanced and working at optimal output.

Some common issues for you to look out for and hopefully prevent throughout the winter include:


Always keep your units free from obstruction to ensure your system doesn’t have to work any harder than necessary. This is important for both outdoor and indoor units.

Make sure nothing is blocking the indoor vents or air discharge points to enable your systems to run as efficiently as possible.


Set your thermostat controls to a reasonable level (even when you first turn on your system!). 23ºC is a reasonable temperature for homes and offices. A temperature of 30ºC for example is excessive and strains units unnecessarily.

When temperatures are cold, it’s important to position the louvers on the indoor units vertically (or as vertically as is possible) to force the heat down into the room and achieve maximum efficiency from your unit.

If a fault code does appear, the common solution of switching it off and back on is often the answer. Be sure to leave the system off for 10 seconds before restarting. The manual reset is the first thing any engineer will try when called out so save yourself some money by trying it yourself first.


When running in heating mode, air conditioning units stop producing heat from time to time. This allows the system to enter defrost mode, which is necessary to prevent ice and frost building up in the condenser coil. If you are not sure what is happening, wait to see if they start producing heat again before calling someone out.


Room air conditioner units feature a thermostat sensor. It’s located behind the control panel and measures the temperature of air coming into the evaporative coil. If the sensor is knocked out of position, the air conditioner could cycle constantly or behave erratically. The sensor should be near the coil but not touching it; adjust its position by carefully bending the wire that holds it in place.


If you’re using your air conditioning unit a lot during the winter months you’ll tend to find your filter gets a lot dirtier. This build up of dirt can cause a restriction in the air flow causing a knock on effect that makes the furnace have to work twice as hclean_and_dirty_ac_filter_magnificent_airard to maintain the right temperature. Simply check your filters at the very least once a month and replace them when necessary.




People often see water leaking from their outdoor condensers and assume that something is wrong. However, often when the condensers are surrounded by melting snow and ice, it’s completely normal for that to happen when in heating mode.ac-leaking-water

CAUTION: Is there a public walkway or footpath beneath the condensers? The leaking water can turn into a slipping hazard if it freezes. Divert the water and allow it to drain into a safe area.
