Hello, I am Heidi, and this is my blog devoted to HVAC issues, repair, troubleshooting, maintenance tips and more. Before you dive into my posts, let me introduce myself. I am a mum of three kids and married to an amazing husband. I used to work in the HVAC industry, but now I spend most of my time working as an editor from my house. I needed something that offered the flexibility of staying at home with my little ones, but I miss the hands-on nature of HVAC work. In this blog, I plan to post on a variety of HVAC related topics.

How to Ensure Your New Ducted Air Conditioner Lives Up to Its Energy Efficiency Standards

Modern air conditioning units come with components and features designed to promote optimal cooling while using little energy. However, certain factors can undermine the efficiency of the unit after installation. Therefore, despite having a high energy efficiency rating, your AC may still consume a lot of power during cooling. Therefore, as you install a new ducted system, consider the following factors that will ensure your AC lives up to its efficiency standards.

Size the air conditioner correctly

Improper sizing of a ducted air conditioner can affect energy efficiency. If the air conditioner is too big, it will cool the home quickly, which will cause it to start up and turn off a lot more. The resultant short cooling cycle will cause premature wear and tear on the components. Choosing an AC with a high cooling capacity doesn't translate into increased energy savings. To maximise the efficiency of your new air conditioner, size it to your home's cooling demand. If the unit is too small or too big, it won't be as efficient as it should be.

Seal and insulate ductwork

Air ducts should not allow any external factors to influence the temperature of the air. Unfortunately, if your ductwork is uninsulated or has leaks, the air will absorb heat from the surroundings. Consequently, the AC will consume more energy to cool the air to the pre-set thermostat settings. Before reusing old air ducts, inspect them for leaks and insulation issues. Insulate and seal your ducts to prevent heat transfer between the air and the surroundings. Proper duct sealing and insulation will ensure that your AC cools your home fast without consuming a lot of energy.

Observe timely maintenance

Ducted air conditioners may become less efficient over time due to age. However, with proper maintenance, you can maintain the efficiency of your new unit for a longer period. Below are some maintenance tasks that will lower your unit's energy consumption:

  • Clean AC filters: Dirty filters inhibit airflow and cause air conditioners to overwork. Clean the unit's filters regularly to optimise airflow and prevent premature wear of the components.
  • Clean ductwork: Dirty and clogged air ducts can cause your unit to overheat and fail. Regularly cleaning the ducts will not only boost efficiency but also improve air quality.
  • Monitor airflow: Poor airflow can undermine your air conditioner's efficiency by causing hot and cold spots around the home. Regularly monitor airflow across the cooling system's zones to optimise the unit's performance.

Inspect and service your ducted air conditioner annually to maintain its efficiency. Timely maintenance will also unearth issues that would have cost a lot of money to fix.

As you install your new ducted air conditioner, take the above measures to maintain its efficiency. Contact an HVAC contractor for professional ducted air conditioning installation services.
