When the summer heat peaks in St. Louis, your air conditioner becomes your home’s lifeline. To keep your AC running smoothly and efficiently during the hottest months, regular maintenance is key.
Neglecting simple maintenance can cause your system to struggle, leading to increased energy bills and a higher risk of breakdowns at the worst time. Whether you’re a DIY enthusiast or prefer to call in a pro, these four maintenance tips will help you survive and thrive through the mid-summer heat.
1. Change or Clean Your Air Filters Regularly
Dirty air filters are one of the most common causes of AC inefficiency. As filters collect dust, pollen, and other particles, they restrict airflow, forcing your system to work harder to cool your home. This not only raises energy consumption but also puts extra strain on components, potentially leading to premature wear.
DIY Tip: Check your air filters every month during the cooling season and replace or clean them at least every 1 to 3 months. If you have pets or allergies, you may need to change filters more often. A clean filter improves airflow, boosts indoor air quality, and helps your AC operate at peak efficiency.
2. Keep the Outdoor Unit Clean and Clear
Your outdoor condenser unit is exposed to weather, dirt, leaves, and grass clippings, all of which can accumulate on the coils and fins. When debris builds up, it blocks heat transfer, reducing the unit’s efficiency and cooling power.
DIY Tip: Regularly inspect the outdoor unit and gently remove any debris with a soft brush or hose (using a gentle spray). Avoid using high-pressure water, which can damage delicate fins. Make sure at least two feet of clearance surrounds the unit for proper airflow. Trim back shrubs, plants, and grass to prevent obstruction.
3. Optimize Your Thermostat Settings
Your thermostat is the control center for your comfort and energy use. Setting it too low doesn’t cool your home faster; it only causes your system to run longer and consume more energy.
DIY Tip: Set your thermostat to a consistent temperature, ideally around 75°F when you’re home and a few degrees higher when you’re away. Consider installing a programmable or smart thermostat to automatically adjust temperatures based on your schedule. This reduces wasted energy while keeping your home comfortable.
4. Know When to Call a Professional
While many maintenance tasks are homeowner-friendly, some AC issues require expert attention to prevent costly repairs or system failure.
Call our team if you notice:
- Unusual noises like grinding, squealing, or banging
- Persistent water leaks or ice buildup on coils
