Tilted AC Unit? Here’s What You Need to Know

As homeowners, we all want our air conditioning systems to run smoothly and efficiently. But what happens when you notice your AC unit is tilted? While it may not seem like a major issue at first, a tilted AC unit can actually lead to serious problems down the road.

The Dangers of a Tilted AC Unit

Vibration and movement: When your AC unit is tilted, it can vibrate excessively and even move off its pad. This can damage the unit itself and lead to costly repairs.

Kinked refrigerant lines: In extreme cases, the vibration can cause the refrigerant lines to kink, which can restrict the flow of refrigerant and compromise the efficiency of your system. Imagine it’s like a microwave cord getting kinked after falling from the counter; it’s the same principle, just with much higher stakes!

Uneven drainage: A tilted AC unit may not drain properly, causing water to pool around
the unit and potentially lead to leaks and damage to your foundation.

Should You Be Worried?

While a slight tilt is nothing to be overly concerned about, it’s important to keep an eye on the situation and take action if the tilt becomes more pronounced. Remember, prevention is key!

The Proper Way to Relevel Your AC Unit

If your AC unit is tilted, calling a professional technician is the best course of action. They will:
  • Pump down the system: This involves removing the refrigerant from the AC unit.
  • Cut the refrigerant lines: This allows the unit to be safely moved.
  • Disconnect the power: This ensures the safety of the technician and prevents damage to the unit.
  • Remove the unit from the pad: This allows access to the pad for leveling.
  • Take out the pad completely: This allows for proper re-landscaping and foundation work.
  • Reinstall the unit: Once the pad is level and the landscaping is complete, the unit can be safely reinstalled.

When Replacement Might Be a Better Option:

In some cases, especially with older or failing AC units, it may be more cost-effective to replace the unit entirely rather than attempt to relevel it. If your unit is nearing the end of its lifespan, this may be the wisest choice.

By understanding the dangers of a tilted AC unit and taking appropriate action, you can ensure your system runs smoothly and efficiently for years to come. Remember, if you’re unsure about the severity of the tilt or how to proceed, it’s always best to consult with a qualified professional.
