Green Comfort: How HVAC Contractors Help With Energy Efficiency

Good day. My name is Darryl and I work as a government researcher for the energy sector. I prepare reports which suggest ways that energy can be conserved and made cheaper. One area that is particularly under the spotlight is the effect of heating, ventilation and cooling systems on the environment. Whilst preparing my latest research report, I have been amazed by the energy efficiency that can be gained by installing the right HVAC systems. I even contacted professional HVAC contractors to upgrade, maintain and repair the systems in my own home because I learnt that older systems can use more energy without regular checks. I'm sure that there are others like me who aren't aware of the importance of choosing the right HVAC system. I hope to share a little of what I have learnt in my blog and help spread awareness. Thank you for your time.


Keep it Clean: How to Clean a Ducted Air Conditioning System

Because you can't see the ducted air conditioning system in your home, it is easy to forget that it needs cleaning now and again. If you do not keep the system clean, it can become filled with dirt, dust and debris. This can affect the efficiency of your air conditioning system and impact on the air quality in your home. Below is a brief guide to cleaning your ducted air conditioning system.

Clean the grates

The first step you need to take is to ensure that your air conditioning system is turned off. If you attempt to clean the ducts with the system running, you may introduce additional dirt and debris into the system as you attempt to clean it. Next, locate and remove the grates covering the system's air ducts. While it is possible to lift some grates to remove them, others may be secured in place and require you to use a screwdriver to unscrew them. You should soak the grates in a bowl containing warm water and a squirt of liquid detergent to remove any grime and dirt. While they are soaking in the bowl, you should continue cleaning the rest of the system.

Remove objects and debris from the duct

With the grates removed, you should be able to inspect the air ducts themselves. You should check that no large objects or debris are blocking the air duct. You may be surprised at the range of objects which can find their way into your air conditioning system, particularly if you have small children or pets. If you spot something, put on some work gloves and reach into the duct to remove it.

Vacuum the ducts 

Once you are sure that you have removed any large objects, you can vacuum the duct to remove smaller particles of dust and dirt. You should use the hose attachment on your vacuum cleaner as this will enable you to reach as far into the duct as possible. You should then wipe out the entrance to the duct using a soft cloth. You can then reattach the grate covers and turn on your air conditioning system, safe in the knowledge that the air ducts are clean and the system is running efficiently.

If you have any questions or concerns about your ducted air conditioning system, you should contact a professional HVAC contractor who will be able to offer help and assistance.
