You might be wondering why do air conditioners ice up? After all, your air conditioner isn’t usually cooling that much.
However, there are a few good reasons as to why your air conditioner behaves this way, and we’re going to take a look at these reasons now.
Air conditioners ice up for a number of reasons
There are a few reasons why air conditioners ice up, and you’ll find that this article will help you understand what is happening and how you can prevent it. Don’t worry, we won’t use any of the technical terms that some websites use because we want to explain it simply and plainly so you understand what’s happening so you can resolve the issue quickly and with little fuss.
Reason 1: The airflow is blocked
A common reason that air conditioners ice up is that the airflow is restricted. The culprit is likely to be an air filter that has become blocked, which prevents cool air from moving.
The good news is that you can unblock your air conditioner relatively easily. You simply just need to clean or change your air filter regularly. If you cannot unblock or change the filter yourself, hire a contractor to do the work for you.
Follow these instructions to unblock your air filter:
- Switch your air conditioner off
- Turn the fan(s) on for at least 1 hour
- After 1–1.5 hours, turn the fans off
- Change the air filter
- Turn your air conditioning system back on
- Set your air conditioning system to cool
- Your air conditioner should now be working perfectly
Before the weather starts to get hot again it would be a good idea to get your air conditioner serviced so you stop any issues in their tracks. Ask a HVAC engineer to check your filter during the cooler months so you can use it trouble-free during the warmer months.
Reason 2: Refrigerant leaks
If the issue with your air conditioning system is not caused by a blocked air flow, it could be caused by a leak. However, if you have a leak in your system, you will need to get it fixed as soon as you can.
You may want to think about buying a new air conditioning system, but if you would rather not spend the money you can always get it fixed. Hire a HVAC company to temporarily fix the issue by topping up the coolant or Freon levels.
Topping up your coolant or Freon levels will not solve the issue, but it could help to buy you some time before you need to purchase another A/C.
Please note that you should not attempt to top up the coolant or Freon levels yourself; you will need the help of a licensed professional who can safely do the work for you.
Air conditioning systems can be something of a lifesaver during the hot summer months, but they can break down from time to time. However, if you know what to look out for, your air conditioning system could potentially last you for years.
