12 Ways to Improve Your AC Efficiency with Repair and Maintenance

Maintaining your air conditioning (AC) system is key to ensuring it runs efficiently, especially during those hot summer months. Not only does regular maintenance extend the lifespan of your unit, but it also helps you save on energy bills. In this blog, we’ll explore some simple yet effective ways to improve your AC efficiency through timely repair and maintenance.

1. Clean or Replace the Air Filter

A clogged or dirty air filter restricts airflow, making your AC work harder than it needs to. This can lead to higher energy consumption and reduced efficiency. Ensure you clean or replace the air filter every one to three months, depending on usage. Dirty filters not only impact the performance of your AC but can also degrade indoor air quality, leading to potential health concerns.

Regularly checking your air filter is a simple task that can have major benefits. It’s particularly important during peak seasons when your AC unit is likely working the hardest. Maintaining a clean filter ensures that your system can easily circulate air, keeping your home cool and comfortable while reducing strain on the unit.

If you’re unsure how to replace your air filter, consult your AC unit’s manual or check for resources online. Replacing a filter typically involves removing the old one and inserting a new one in its place. Make sure to choose the right type and size of filter for your system to ensure optimal performance.

2. Schedule Regular Professional Maintenance

A professional technician can identify and fix minor issues before they become major problems. Scheduling a tune-up at least once a year can significantly improve your AC’s performance and efficiency. A comprehensive maintenance check generally includes cleaning coils, checking refrigerant levels, inspecting ductwork, and ensuring the thermostat is functioning correctly.

Apart from preventing major repairs, regular maintenance also helps in identifying worn-out parts that need replacement. This proactive approach can save you from unexpected breakdowns during the peak summer months, ensuring uninterrupted comfort. Knowing when to call a technician is crucial; if you’re unsure, consult our guide on how do you fix an ac if it’s not working for more information.

3. Keep the Outdoor Unit Clean

The outdoor unit can collect dust, leaves, and debris, which can obstruct the airflow and hinder performance. Clean the unit regularly and make sure it has at least two feet of clearance on all sides. Consider using a garden hose to gently rinse off accumulated dirt, but avoid using high-pressure washers as they can damage sensitive components.

Trim back any plants or shrubs surrounding the unit to maintain adequate airflow. Additionally, periodically checking for insect nests or other obstructions around the unit can help maintain optimal performance. Regularly cleaning your outdoor unit enhances your AC’s efficiency and extends its lifespan.

4. Check and Seal Ductwork

Leaky ducts can cause up to 30% of air to escape, leading to higher energy bills and reduced efficiency. Ensure your ducts are properly sealed and insulated to prevent leaks. You can use mastic sealant or metal tape to close minor leaks, but for extensive ductwork issues, it’s best to consult a professional.

Regularly inspecting your ductwork for signs of wear and tear can catch problems before they become severe. This includes looking for visible tears, loose joints, or disconnected sections. Properly sealed ducts ensure that cooled air reaches every room efficiently, maintaining a consistent home temperature.

5. Monitor the Thermostat Settings

Set your thermostat to a comfortable yet energy-efficient level. Consider investing in a programmable thermostat to automatically adjust the temperature based on your schedule. This can reduce unnecessary energy consumption when the house is empty or during nighttime when cooler temperatures prevail.

A programmable thermostat can save you significant amounts on energy bills by optimizing your cooling strategy. Smart thermostats even offer advanced features such as remote control via smartphone apps, learning your temperature preferences over time for better efficiency. For guidance on installation and setup, you may want to check professional resources or have a technician handle it.

6. Ensure Proper Insulation

Proper insulation keeps the cool air inside and the hot air outside. Insulate your home effectively to reduce the burden on your AC unit. This includes attic insulation, sealing windows and doors, and ensuring walls and floors are adequately insulated.

Investing in high-quality insulation materials can have long-lasting benefits on your home’s energy efficiency. Not only will it reduce your cooling costs in the summer, but it also helps in maintaining warmth during the winter, offering year-round benefits. Regularly inspect your home for any cracks or gaps and seal them promptly.

7. Use Ceiling Fans to Assist

Ceiling fans help in circulating the cool air more effectively, allowing you to raise your thermostat by a few degrees without sacrificing comfort, thus saving energy. Ensure ceiling fans are set to spin counterclockwise during the summer months to push cool air downward.

Running ceiling fans costs significantly less than running your AC unit, especially during mild days. Use fans strategically in occupied rooms while keeping doors and windows closed to maximize cooling efficiency. Remember to turn off fans when rooms are unoccupied, as they only cool people, not spaces.

8. Avoid Heat Buildup During Peak Hours

Reduce the use of heat-generating appliances during the hottest part of the day. This can lessen the load on your AC unit and improve its efficiency. Cooking, using dishwashers, and running clothes dryers can significantly increase indoor temperatures.

Consider cooking meals during cooler hours or using a microwave instead of an oven. Using appliances like dishwashers and clothes dryers in the evening or early morning can also make a difference. Additionally, keep blinds closed during peak sun hours to minimize solar heat gain.

9. Keep Vents Unblocked

Furniture, curtains, or other items obstructing vents can cause uneven cooling and force your AC to work harder. Ensure all vents are free from obstructions for proper air circulation. Regularly inspect vents to make sure they are clean and open, allowing for maximum airflow.

If you have rooms that are seldom used, you might be tempted to close the vents in those areas. However, this can unbalance your AC system and cause wear and tear. Instead, maintain an open vent policy throughout your home to ensure efficient cooling.

10. Check and Maintain the Refrigerant Level

Low refrigerant levels can cause your AC to underperform and reduce its efficiency. Have a professional check and refill the refrigerant if necessary. A refrigerant leak can not only decrease your AC’s efficiency but also pose environmental hazards.

Handling refrigerant requires specialized knowledge and equipment, so it’s not typically a DIY job. Regular maintenance checks by professionals can ensure that refrigerant levels are optimal and there are no leaks in the system. If you suspect an issue, consult KadeCo Inc. for reliable services.

11. Inspect and Clean the Evaporator and Condenser Coils

Dirty coils can reduce your AC’s efficiency by limiting the heat transfer process. Clean the evaporator and condenser coils annually to maintain optimal performance. Use a soft brush to gently clean the coils, or consider hiring a professional for this task.

Cleaning coils not only boost efficiency but also prolong the life of your AC unit. Neglecting this maintenance task can lead to higher energy consumption and even system failures. Regularly inspecting and maintaining these components ensures your AC is running at peak performance.

12. Install a Smart Thermostat

A smart thermostat can learn your schedule and adjust the temperature accordingly, optimizing energy use. It’s a great investment for improving your AC’s efficiency. Many smart thermostats come with features that offer insights into your energy usage, helping you identify ways to save.

Smart thermostats are easy to install and can be controlled remotely via smartphone apps. This allows you to adjust the temperature even when you’re not home, ensuring comfort upon arrival and enhancing energy savings.
