Is your air conditioner struggling to keep your home cool? A common culprit is an unevenly installed unit. A properly leveled AC unit ensures efficient drainage, optimal airflow, and prevents premature wear and tear. This guide provides a step-by-step process on how to level your AC unit yourself. Before you begin, it's crucial to turn off the power to the unit at the breaker box for safety.
Assessing Your AC Unit's Level
Before grabbing your tools, you need to determine if your unit actually needs leveling. Look for these signs:
- Pooling water: Water accumulating around the base of the unit indicates improper drainage, often caused by an unlevel unit.
- Unusual noises: Rattling or vibrating sounds could signify an uneven base, causing parts to rub against each other.
- Inconsistent cooling: If certain areas of your home are significantly warmer or cooler than others, an unlevel AC unit could be the cause.
You'll need a level (a bubble level works best) to accurately assess the situation. Place the level on top of the unit's base in multiple directions—front to back and side to side—to determine any inconsistencies.
Tools and Materials You'll Need
Gathering the necessary tools beforehand makes the leveling process smoother. You'll likely need:
- Level: A sturdy bubble level, at least 12 inches long.
- Shims: These are thin wedges (usually metal or wood) used to adjust the height of the unit. Choose shims appropriate for the material of your AC unit's base.
- Wrench (or socket): The size will depend on the type of bolts securing your unit.
- Screwdriver: May be needed depending on the type of shims used.
- Measuring tape: For precise measurements.
- Gloves: To protect your hands.
- Safety glasses: For eye protection.
Step-by-Step Guide to Leveling Your AC Unit
1. Prepare the Area: Clear the area around your AC unit to provide ample workspace.
2. Check the Level: Place the level on the unit's base in both directions. Note any deviations from level.
3. Adjust with Shims: Carefully slide shims under the low side(s) of the unit. Use multiple shims if necessary to achieve a perfectly level position. Start with small adjustments and recheck the level frequently.
4. Tighten Bolts: Once you've achieved a level position, securely tighten the bolts holding the unit in place.
5. Recheck the Level: After tightening the bolts, double-check the level again to ensure the unit remains level.
6. Test for Proper Drainage: Turn the power back on to your AC unit and observe the drainage for a few hours. Look for any further water pooling.
7. Consult a Professional (When Necessary): If you are uncomfortable performing this task or if your unit remains unlevel despite your efforts, it's best to contact a qualified HVAC technician.
Preventing Future Leveling Issues
Regular maintenance can help prevent your AC unit from becoming unlevel:
- Annual Inspections: Schedule an annual inspection by a professional to identify and address potential issues early on.
- Check for Debris: Regularly clear any debris from around your AC unit. This can cause uneven settling.
- Foundation Issues: If your AC unit consistently becomes unlevel, there might be underlying foundation problems. Contact a foundation specialist for assessment and repair.
By following these steps, you can improve the efficiency and longevity of your air conditioning unit. Remember, safety is paramount, so always prioritize caution and don't hesitate to call a professional if you're unsure about any part of the process. Leveling your AC unit is a worthwhile DIY project that can significantly impact the cooling comfort of your home.
