To those outside the Lansing area, the state of Michigan can seem like a cold and forbidding place, the home of endless winters and subzero temperatures. To the residents of Lansing, the weather patterns of the area are far more subtle, and far more changeable.
If you live here, you know that the summers in Lansing can be downright hot. You also know that having reliable air conditioning is a very big deal and that when your AC freezes up your comfort is severely compromised. What you may not know is why your AC keeps freezing up, or what to do to prevent this common problem.
A Number of Different Causes
There are a number of reasons why a previously reliable air conditioning unit would suddenly freeze up, so it is best to work through the possibilities one at a time. It pays to start with the most common problems since those issues are more likely. If those potential issues are not in play, you can move down the list until you find the real culprit.
It is important to keep a close eye on your air conditioning unit, both before and after the summer months. Sweeping snow and ice from your outside unit during the cold winter months will protect the system and reduce the odds of freezing up and other common problems.
If your air conditioning unit suddenly freezes up and no longer keeps your Lansing home cool, the first thing you should check is the refrigerant level. If it has been some time since your AC was charged, it could simply be low on refrigerant.
Every time you turn on your home air conditioning unit, you use up some of the refrigerants. Over time, the refrigerant level can drop to very low levels, causing the system to freeze up unexpectedly. If this is the problem, charging the system with new refrigerant should be enough to restore your Lansing area home to comfort.
A Bad Fan
A malfunctioning or broken fan can also cause your AC to freeze up and stop working, and that should be the next thing on your list. Without a functioning fan to move the air around, the refrigerant inside the unit can freeze up, leaving you without the cool air you need to survive the hot summer months.
It is not always easy to spot a malfunctioning fan, and you may need to call in an expert to help you with the diagnosis.
