Like any other technology, air conditioners experience their share of operational problems. But while loud noises and dripping water fall on the ‘normal’ end of the spectrum, frozen internal systems – that too in the middle of the summer season – can definitely be categorized as ‘weird.’ After all, isn’t the whole point of an AC to cool your home? How does a thin layer of ice develop on your machine? The truth is, AC repair personnel receive numerous such complaints every year. Thankfully, there are ways to address the problem before any harm is done.
1. Check Your AC Coolant Levels
AC coolants not only maintain cooling efficiency but also maintain system pressure. So, when your coolant supply is depleted, the various components get affected and even lead to frozen ACs. So, it is essential to check the refrigerant levels from time to time and call your technician to get them replenished , if necessary.
2. Remove Obstructions for Better Airflow
Insufficient airflow is often the cause of an AC unit freezing up. With inadequate airflow, the temperature of coils drops down drastically, sometimes below the freezing point. The moisture in the air condenses, ultimately leading to an ice build-up. Therefore, check your ductwork for any airflow obstruction. What you need to do is open all the supply or return vents around your home, and ensure no objects like drapery, clothing, or furniture blocks the openings. Here is how you can go about it:
The entire point of AC vent filters is to facilitate airflow. So, clogged or restricted components malfunction and freeze the system. Change the air filters if they appear dirty and discolored.
Dirt and dust collect on the cooling coils and fins of the AC evaporator and cause the machine to freeze. Gently remove particles from the evaporator by using a soft brush.
Keep all the supply registers in your home open. Blocked register prevent smooth airflow from AC vents, and produce abnormal cooling effects.
Ice on your AC does come as a bit of a shock when homeowners witness a phenomenon like that for the first time. But following the simple measures mentioned above can provide relief from this problem and nip it in the bud. However, if none of these techniques produce the desired effect, it’s time to call in the experts. Click here to contact a reputed AC service professional.
