Air conditioners operate on fine tuning, there are only a few reasons why your unit is freezing.
Some of the main reasons why a condenser or evaporator coil can freeze:
- Is your air filter dirty?
- Does the indoor fan blow air?
- Is the evaporator coil dirty?
- Are the refrigerant levels charged accurately?
Changing a filter is a simple and easy maintenance item, be we can all forget to do even the simple things, so double check before calling us.
When you turn on the A/C the fan inside should be blowing air through your home, if it isn’t, you’ll find ice all over the condenser and evaporator coil within minutes.
Having a clogged evaporator coil, is equal to having a dirty filter, either way the pressure will become trapped, therefore causing ice, depending on how congested the coil is, it might seem like the A/C is working and later ice or it could be moments after turning it on.
If all the above has not answered the question, Refrigerant levels not being accurately charged will result in your HVAC system freezing, the difference here is that the unit will run for hours, while not actually cooling your home and costing energy.
