During the summer, outdoor air conditioning units help sustain indoor comfort. Routine care confirms that they work well during spring and summer. Paying attention to the care of the external unit helps maintain a stable indoor environment without overworking the system. Here are five tips for maintaining outdoor units with the help of an air conditioning service company:
1. Clear the Surrounding Area
For an outdoor AC unit to work effectively, it must have unobstructed airflow. If leaves, branches, grass clippings, or overgrown shrubs are near the unit, it may not function properly. Leave a few feet of open space around the unit in all directions to allow for ventilation and access for air conditioning service technicians when necessary.
After a storm or yard work, check the area and remove any objects in the way. Mowing and trimming the area often will help stop the buildup of leaves. If outdoor furniture, tools, or landscaping materials are too close to the unit, they may affect its performance.
2. Inspect Refrigerant Line Condition
Refrigerant lines transport the refrigerant and are typically covered with insulation to maintain their efficiency. Over time, the insulation may deteriorate due to exposure to sunlight, weather changes, or natural wear. If the insulation is damaged or begins to peel, it can cause the system to lose efficiency due to changes in the refrigerant’s temperature. Checking the refrigerant lines during each season can help you notice any worn or missing protective covering. If the insulation is damaged, an experienced technician will carefully remove and replace the material.
3. Monitor the Unit Leveling
Most outdoor air conditioning units are placed on a stable concrete pad or base. Soil erosion, tree roots, and freeze-thaw cycles can gradually make the unit tilt or become uneven. A slight tilt can affect the internal components and cause vibrations that disrupt the unit’s performance or accelerate wear. Checking the unit’s level and stability during each season can help prevent these problems. If you notice the base moving or the unit tilting, correct it as soon as possible.
4. Check for Unusual Sounds
When an outdoor air conditioning unit is running, it usually makes a steady humming sound. This is the usual sound of the compressor and fan working together. When you start hearing new or different noises, it could be a sign that something is wrong with your AC system. If you hear rattling, buzzing, clicking, or grinding sounds, something in the air conditioning needs attention. Loose screws on the panels, misplaced fan blades, or small objects stuck in the grilles can cause rattling noises.
Buzzing sounds could indicate electrical problems with the contactor or transformer. It might also be due to a failing capacitor, which is the part necessary for keeping the motor running. If you hear clicking while the unit is running, it could mean a problem with the relay switch or control board. Sometimes, the system will click as it works, but if you notice frequent or unusual clicking, it should be checked. If you hear a loud, high-pitched sound, it may indicate worn or damaged motor bearings and fans. In such cases, seek professional help to identify these issues promptly.
5. Schedule Regular Seasonal Services
Regular service appointments help maintain the proper functioning of the internal parts, electrical systems, and refrigerant in your HVAC unit. Having your system checked in the spring confirms that you fix any small problems before you need it for daily use. Technicians can access parts of the system that should not be disassembled without training. They consist of sealed electrical boxes and coils that can only be serviced with the right tools.
If you arrange for service early in the season, the unit can be inspected for wear, cleanliness, and proper air circulation. Regular tune-ups help the system last longer by finding parts that might need to be replaced or repaired. Regularly checking your system also allows you to adjust the thermostat or fan speeds, as they may have changed over time.
Hire a Reputable Air Conditioning Service Provider
Taking care of your HVAC system involves more than occasional cleaning. It requires checking significant parts of the system, identifying early warning signs, and making sure the unit is serviced before summer arrives. If you want your air conditioning to work well all summer, work with a reliable HVAC service provider. Schedule your maintenance before the peak demand to keep your unit operating at its best.
