Tips to Keep Your AC From Overheating in the Summer


We’re in for another scorcher of a summer, and that means you’re going to rely a great deal on your AC to keep your home cool. Unfortunately, putting too much strain on your AC can lead to the unit overheating. This is a common issue that can lead to system breakdowns and costly air conditioning repair. Here are some expert tips to help you avoid overstraining your AC and keep it running efficiently all summer long.

1. Regular Maintenance

One of the most effective ways to prevent your AC from overheating is to schedule regular maintenance. An annual check-up before the summer heat kicks in can make a significant difference. Regular maintenance not only helps in identifying potential problems early but also improves your system’s efficiency, reducing the likelihood of overheating.

2. Keep the Outdoor Unit Clean

Your AC’s outdoor unit, also known as the condenser, plays a vital role in the cooling process. It dissipates the heat from your home to the outside air. If the condenser is obstructed by debris, dirt, or vegetation, it can’t perform this function effectively, leading to overheating. To keep your outdoor unit clean regularly remove any leaves, dirt, and debris around the unit and trim any plants or bushes at least two feet away. Occasionally hose down the unit to remove dust and dirt buildup.

3. Change Air Filters Regularly

Air filters are essential for maintaining good air quality and ensuring your AC runs efficiently. Clogged or dirty filters restrict airflow, making your system work harder to cool your home. This increased effort can cause the AC to overheat. We recommend checking the filters monthly and replacing them every 1–3 months.

4. Use a Programmable Thermostat

A programmable thermostat can help manage your home’s temperature more efficiently, reducing the strain on your AC. By setting your thermostat to higher temperatures when you’re not home and lowering it when you return, you can avoid unnecessary overworking of your system. Additionally, smart thermostats can learn your schedule and adjust settings automatically, providing both comfort and efficiency.

6. Avoid Heat-Generating Activities During Peak Hours

During the hottest parts of the day, activities that generate a lot of heat can make your AC work harder. Try to minimize the use of appliances like ovens, stoves, and dryers during peak hours. Instead, consider cooking meals in the early morning or late evening, using a microwave or outdoor grill, and air-drying clothes instead of using the dryer.

7. Use Fans and Ventilation

Ceiling fans, box fans, and ventilation systems can assist your AC by circulating cool air and reducing the overall temperature in your home. Fans use less energy and can create a wind-chill effect that makes you feel cooler. By using fans in conjunction with your AC, you can set your thermostat a few degrees higher without sacrificing comfort, thereby reducing the strain on your system.

By following these tips, you can help prevent your AC from overheating and ensure it runs smoothly throughout the summer. If you need professional assistance or have any concerns about your AC, don’t hesitate to contact our team. We’re here to keep you cool and comfortable all summer long.
