10 Energy-efficient Air Conditioning Tips for Your Concord Home

Having an air conditioner is essential for maintaining a comfortable home. Efficiency is a crucial aspect to consider when choosing an air conditioner, as it affects both energy costs and the environment. Apart from cooling your home and maintaining comfort, it uses less energy for its operation and contributes to reduced energy consumption and a smaller carbon footprint. In this article, we have mentioned some of the energy-efficient air conditioning tips for you. Let’s get started!

Tips to Improve Your Air Conditioning Efficiency

1. Clean or Replace Air Filter

The first step to improve your air conditioning efficiency is to check and change the air filter. ACs have a built-in air filter or a separate air filter in the ductwork, which needs to be changed every six months. Depending on the living conditions, the frequency may vary. Ensure that the air filter is of high-quality fibres and do not let it come in contact with water or damp air.

If you are a pet owner or have allergies, you need to change the air filter more frequently than usual. Always check your air filter first if there is an issue with not cooling well.

2. Partially Open your Windows

We often like to open the doors and windows in the summer to breathe the fresh air outside. It is the hardest habit to break and works against you. When the temperature is high during summer, the warm air will enter the home and until you close the doors again, it will be there. Instead of fully opening the doors and windows completely, try opening them partially so that you can get some fresh air and light while maintaining the home cool and comfortable.

3. Ensure no Leaks From Ductwork

If there are any leaks in your ductwork, you will be losing the cool air to the places that you don’t need, like the basement or attic. For air leaks, you can use aluminium foil or mastic sealant in the places where you can access and reduce the amount of air leaks. If there are leaks that are hard to reach, contact HVAC experts so that they can test ducts, detect air leaks, and seal them for you.

4. Clean The Outdoor Unit

Over time, debris will accumulate around the outdoor unit, which can affect the efficiency of the air conditioner. Ensure that there is no debris or other objects that are blocking the unit, and clear them whenever required. You can also clean it by opening the panels. It is recommended to create a shade over the outdoor unit during summer so that it will not have to work hard.

5. Use The Right-size AC

The efficiency of the AC unit also relies on the size of the unit. Ensure that the AC is neither too big nor too small for your room. You can make use of a room calculator to know the size that fits your room. If you have multiple rooms, use smaller units for each room instead of one oversized unit. By this approach, you can run the AC whenever required and keep your electricity costs lower.

6. Upgrade Your Insulation

Upgrading the house insulation can be a challenging and expensive job. But if you are doing attic insulation, it can be a DIY project. Attic insulation is highly important during summer as it blocks the hot attic air. If you are unsure about your insulation upgrade, contact your HVAC expert for an energy audit. They will use specialised equipment to detect the heat leaks and suggest the best fixes to maintain comfort in your home.

7. Replace Your Air Conditioner if Required

Installing a new air conditioner can be an expensive option, so it’s best to plan accordingly. But if you are using an outdated air conditioner, it can cost more in terms of energy bills. So, even if it’s delayed, it’s better to upgrade your air conditioner. Ask your HVAC technician to run the inspection and know about the condition so that you can plan for your air conditioner.

8. Avoid Using Heat-Generating Appliances When AC is on

Home appliances like an oven or a hair dryer generate hot air during their functioning, which makes it difficult for your air conditioner to cool your home. You can avoid this if you stop using the heat-generating home appliances when the AC is on. Following this can improve the efficiency and lower the energy bills.

9. Use Sleep Mode

When you set your air conditioner to sleep mode, it automatically adjusts the fan speed and the temperature to maintain a comfortable environment during the night. The temperature slowly increases by 1 degree for every hour, reaching 78°F, and then alters within six adjustments.

10. Schedule Annual Maintenance

Schedule an annual AC tune-up for your air conditioner. If the air conditioner is over 10 years old, schedule maintenance every six months. The AC has many mechanical and electrical components that may wear out. A regular AC tune-up ensures that potential issues are detected and fixed. A regular tune-up not only improves efficiency but also extends the lifespan of your system.

Conclusion

As mentioned above, you can implement various things to improve the efficiency of your air conditioner system. The key point here is to observe the energy bills and adjust your habits whenever required. By these small and simple changes, you can ensure that the AC stays in a better shape and maintains your home cool all summer long.
