Hey there! As an Outdoor AC supplier, I've seen my fair share of outdoor AC units, and one of the most crucial steps in ensuring their optimal performance is leveling them properly. In this blog, I'll walk you through the process of how to level an outdoor AC unit, so you can keep your cool and your unit running smoothly.
Why Leveling Matters
Before we dive into the how-to, let's talk about why leveling your outdoor AC unit is so important. An unlevel AC unit can lead to a whole host of problems, including:
- Uneven Wear and Tear: When an AC unit is not level, it puts extra stress on certain parts of the compressor and other components. This can cause premature wear and tear, leading to costly repairs or even the need for a replacement unit.
- Poor Performance: An unlevel unit can also affect the efficiency of your AC system. It may not cool your space as effectively, leading to higher energy bills and a less comfortable indoor environment.
- Noise and Vibration: A tilted AC unit can cause excessive noise and vibration, which can be a nuisance for you and your neighbors.
Now that you understand the importance of leveling, let's get started on the process.
Step 1: Gather Your Tools
Before you begin, you'll need to gather a few tools to help you level your outdoor AC unit. Here's what you'll need:
- Level: A good quality level is essential for this task. You can use a bubble level or a digital level, depending on your preference.
- Shims: Shims are thin pieces of material that you can use to adjust the height of the AC unit. You can find shims at your local hardware store.
- Wrench: You'll need a wrench to loosen and tighten the bolts that hold the AC unit in place.
Step 2: Turn Off the Power
Safety first! Before you start working on your AC unit, make sure to turn off the power at the breaker box. This will prevent any electrical shocks or accidents while you're working.

Step 3: Inspect the Unit
Once the power is off, take a close look at your outdoor AC unit. Check for any visible damage or signs of wear and tear. Look for cracks in the unit, loose bolts, or any other issues that may need to be addressed.
Step 4: Check the Level
Place the level on top of the AC unit to check if it's level. If the bubble in the level is not centered, it means the unit is not level. You'll need to adjust the unit to get it level.
Step 5: Adjust the Unit
To adjust the unit, you'll need to loosen the bolts that hold the AC unit in place. Use the wrench to loosen the bolts, but don't remove them completely. Once the bolts are loose, you can use the shims to adjust the height of the unit. Place the shims under the unit where it needs to be raised.
Step 6: Recheck the Level
After you've adjusted the unit, place the level on top of the unit again to check if it's level. If the bubble in the level is centered, it means the unit is level. If not, you'll need to make further adjustments until the unit is level.
Step 7: Tighten the Bolts
Once the unit is level, use the wrench to tighten the bolts that hold the AC unit in place. Make sure the bolts are tightened securely, but don't over-tighten them.
Step 8: Turn On the Power
After you've tightened the bolts, turn on the power at the breaker box. Your outdoor AC unit should now be level and ready to operate.
Tips and Tricks
Here are a few tips and tricks to help you level your outdoor AC unit:
- Use a Laser Level: If you have a laser level, it can make the leveling process much easier. Simply aim the laser at the unit and adjust the shims until the laser is level.
- Check the Level Regularly: It's a good idea to check the level of your outdoor AC unit regularly, especially after heavy rain or strong winds. This will help you catch any issues early and prevent damage to your unit.
- Use a Professional: If you're not comfortable leveling your outdoor AC unit yourself, it's always a good idea to hire a professional. A professional HVAC technician has the tools and expertise to level your unit correctly and ensure it's running smoothly.
