Proper insulation helps keep the cool air inside the ducts and prevents it from escaping, maintaining a consistent temperature throughout your home. By addressing any issues with your ductwork, you can enhance your AC system’s performance and reduce the likelihood of breakdowns during Houston’s hottest days.

Keep Vents Clear

Ensuring that all vents and registers inside your home are unblocked is vital for maintaining proper airflow and preventing strain on your AC system. When vents are blocked by furniture, curtains, or other objects, it restricts the flow of cool air into your living spaces. This not only makes it harder to maintain a comfortable temperature but also forces your AC system to work harder, increasing the risk of breakdowns. Regularly check all vents and registers to ensure they are open and unobstructed. Rearrange furniture and other items as needed to allow for free airflow. Additionally, consider closing vents in unused rooms to redirect cool air to the areas where it is needed most. By keeping vents clear and allowing for proper airflow, you can help your AC system operate more efficiently and reduce the chances of a breakdown during Houston’s heatwaves.

Use Ceiling Fans

Ceiling fans are a valuable complement to your AC system, especially during Houston’s heatwaves. By using ceiling fans, you can enhance the distribution of cool air throughout your home, allowing you to set your thermostat a few degrees higher without sacrificing comfort. Ceiling fans create a wind-chill effect, making the room feel cooler than it actually is. This means your AC unit doesn’t have to work as hard to maintain a comfortable temperature, reducing its workload and the risk of breakdowns. It’s important to ensure your ceiling fans are rotating counterclockwise in the summer to push cool air down. Using ceiling fans in conjunction with your AC system not only helps keep your home comfortable but also promotes energy efficiency and prolongs the lifespan of your AC unit.

Seal Windows and Doors

Properly sealing windows and doors is essential for maintaining the efficiency of your AC system during Houston’s extreme heat. Drafty windows and doors allow cool air to escape and hot air to enter, making it more difficult for your AC unit to cool your home. This additional strain can lead to higher energy bills and increase the risk of breakdowns. To prevent this, inspect the seals around your windows and doors and replace any worn or damaged weatherstripping. Use caulk to seal any gaps or cracks that might be allowing air to leak. Consider using draft stoppers or door sweeps to further minimize air leakage. By ensuring your home is well-sealed, you can maintain a more stable indoor temperature, reduce the workload on your AC system, and prevent costly breakdowns during the peak of Houston’s summer heat.

Shade the Unit

Providing shade for your outdoor AC unit can significantly improve its efficiency and reduce the risk of breakdowns during Houston’s heatwaves.
