3 Tips to Reduce the Need for HVAC Repairs and Increase Unit Longevity

Is Your Air Conditioner Frozen? Learn Why Here

Every air conditioner has the potential to freeze. While this is a strange sight, especially when the temperatures reach triple digits, the fact is, this is when it is most likely to happen. A frozen air conditioner is a very common issue, and in some cases, it’s an easy fix. In other situations, however, you will need the services of an AC repair tech.

Reasons Your Unit May Freeze

One of the first things you have to figure out is why your unit has frozen to begin with. There are two reasons this may happen.

  1. When it is hot outside, the sun is beating down on your home, heating everything up. To counter the heat, the AC kicks on more often than usual. As it’s cooling your home, condensation may begin to build up on the evaporator coil. This is supposed to be kept warm internally, but if this heat isn’t present, the temperature may drop under 32 degrees F and then the condensation may freeze. This is going to create a blockage, which results in more water freezing, intensifying the issue.
  2. Another possible cause is that the AC may be low on Freon or refrigerant. It could be due to a refrigerant leak, which is something that needs to be repaired right away. The refrigerant is what’s responsible for dehumidifying and cooling your air. If there’s no refrigerant present, then your AC won’t be able to cool your home – it is just going to blow air.

How to Handle a Frozen Air Conditioner

One of the first things you should do when you notice that your air conditioner is frozen, is turn it off and allow it to defrost. If it is a warm day, this should not take more than an hour or two. It isn’t safe for the unit to continue running while it is frozen. If you do, the system isn’t going to be efficient, and it may cause damage to the unit’s compressor. Having to replace the compressor is one of the most expensive repairs you will have to make for your unit. All AC units should do the following, regardless of if it is frozen due to issue one or two:

  • Clean and replace the filter
  • Be sure all vents are clear. If there isn’t any breathing room, then heat won’t prevent these freezing issues.
  • When you turn the unit back on, make sure your blower motors are working properly. If they are blowing and not making any strange noises, then it is fine.

If the issue was due to a dirty air filter, or if you have found debris and dirt around the system, then you probably fixed the issue. If that wasn’t the problem, then it may be a good idea to go ahead and call the professionals who can determine the underlying issue and make the needed repairs in a timely and efficient manner. This will help ensure the issue doesn’t occur again, as well.
