Air In Central Heating System

What is it?

Air in the central heating system is simply air that has made its way into the system. This can happen for a number of reasons, but the most common cause is a leak in the system. When there is a leak, air will enter the system and cause the pressure to drop. This can then lead to problems with the circulation of hot water and ultimately, your heating not working correctly. Oftentimes it will be necessary to contact a plumbing and heating specialist for help.


Why does it happen?

There are a number of reasons why air might enter your central heating system.


Leak In The System

As we mentioned above, one of the most common causes of air in the central heating system is a leak in the system. This can happen due to a number of factors, such as loose fittings, cracks in the pipes, or holes in the seals.


If you suspect that there is a leak in your system, it's important to have it fixed as soon as possible.


You can try to repair it yourself, however, if you're not sure how to do this, it's best to call a professional to prevent accidentally causing further damage. Otherwise, you could end up with extensive damage to your home and an expensive repair bill. That is why it is so important to have your system checked and serviced regularly by a qualified technician to ensure that there are no leaks present.


Blower Motor

If you're still having problems with air in your central heating system, it's possible that there is an issue with the blower motor. This is the component that circulates air through the system. If there is an issue with this component, it can cause air to be forced out through the vents which is a problem because you need the blower motor to circulate air in order to heat your home.


If you suspect that there is a problem with your blower motor, it's important to have it repaired by a qualified technician as soon as possible. Only someone with professional training and experience should attempt to repair or replace this component.


Dirty Filters

Another cause of air in the central heating system is dirty filters. When the filters are clogged, they don't allow air to flow freely through the system. This can lead to pressure build-up and eventually, air being forced out through the vents.


If you have dirty filters, the best thing to do is replace them with new ones. This will help to improve air flow and reduce pressure build-up. To avoid this problem, be sure to check and clean your filters on a regular basis.


How to fix it?

In some cases, you may be able to fix the problem yourself. For example, if the issue is with loose fittings, you can simply tighten them up.
