Heating and Cooling: How do Filters Work?

The filters on your heating and cooling equipment are crucial to the performance of the systems themselves. This is why filters need to be well-kept and replaced on a regular basis – but have you considered why filters are so critical and how they work?

In this article, we’re taking a look at this and at how you can prolong the longevity of your filters and, therefore, the lifespan of your systems.

How do Filters Work?

What exactly is the purpose of the filters in your heating and cooling system?

The obvious answer is that filters trap dirt, dust, pollen and debris in the air and prevent you from inhaling the particles. By improving the air quality with the removal of pollutants, the filters ensure the room or space is comfortable all year round, as well as promoting a healthy environment.

But they also keep this dirt from clogging up the system’s coils, improving the efficiency of the machine. Without a filter, your HVAC systems couldn’t run as efficiently as it does.

So, while filters are simple components, they’re also quite crucial at the apertures where air comes into the heating and cooling system. This air is either heated or cooled and then delivered to a room through ducts. The filter cleans the air before it’s pulled in and circulated, which means it immediately catches particles that would, otherwise, stay in the air.

Tips to Extend the Lifespan of Your Systems

Of course, because the filters trap this debris, they become dirty very quickly. In order to ensure they are functioning properly – and last for a long time – you want to have them replaced often. When you do so, you are removing the accumulation of particles and contaminants that impact the performance of the system and make it run overtime.

By boosting the efficiency of your systems, you are also cutting down on its energy consumption levels; so, you can keep your office or warehouse space healthy and clean while lowering the bills and helping the environment.

You may also want to think about whether you need the unit running 24/7. If so, it’s best to keep it in a mode that matches up with room temperature – and you may want to turn it off at times. This is because a filter is likely to clog rapidly if the HVAC system is constantly working.

Another thing that is important to note is that clogged filters are a main cause of failure in heating and cooling system. And, if they’re dirty, pollutants can start to accumulate in the ducts of the system instead, which will damage it.

When Should You Replace Your Filters?

There are several signs that will tell you when it’s time to switch the filters for new ones. For example, if you haven’t done it in a long time, consider going ahead now – if you’re unsure whether or not to replace it, we can help. We specialise in heating and cooling systems, as well as their maintenance, so we know everything there is to know about these components.

If you’re paying more on your electric bill but don’t understand why, it may be that the filter is too dirty, and the system is trying to compensate for that by working harder.

When a filter is not working properly anymore and can’t, therefore, filter out dust and other pollutants, you’ll notice it in your office, hospital or factory floor. While dust is natural and accumulates fairly quickly, it can mean your filter needs replacing if you’re noticing a higher amount than usual.

There’s also value in inspecting the filter visually, if this is possible, which will let you know whether the filter is too dirty or clogged up.
