Is your AC freezing up on you? In the middle of summer, it can be shocking to see a lump of ice sitting on your outside air conditioning repair service. However, the ice on the outside of the unit is often so thick that it is invisible. You might not expect your air conditioner to freeze up during the heat, but it actually happens more often than you might think.
If you suspect that your air conditioner has frozen up, reading on will tell you what causes this problem, what to do if this happens to you, and how to prevent this from happening again. And if you still can’t figure it out, contact https://www.airconservicing.org/.
When Does Your HVAC System Freeze And Why?
In the winter, keeping warm is important for more people than just you. Your heating and ventilation system is at risk of freezing if the temperature drops drastically. A frozen heating system is useless for heating a home and can cause the system to fail completely.
· Build-up Of Ice:
In severe cold weather or if you haven’t been keeping up with routine maintenance, your system may freeze up despite the defrost unit’s best efforts to keep it running. That’s why maintenance is necessary, and for that, you can contact marvellous experts.
If ice forms on the outside coils, your heating system will shut off. The coils in your heater are a crucial part of the system that keeps your home warm. Air entering the system is warmed by the coils before being released into the residence. If there’s too much ice on the coils, they won’t be able to warm the air flowing over them, rendering your heating system ineffective.
· The Cycle Of Defrosting:
While complete freezing of the unit should be avoided at all costs, some freezing of the system is to be expected during the colder months. Your outdoor HVAC system is equipped with a defrost cycle to assist in keeping it from freezing over when the temperature drops.
The defrost cycle on your outdoor heater runs at regular intervals (every hour, every half-hour, or every 90 minutes). The unit will pump cool air inside while venting hot air outside, helping to keep your HVAC system from freezing up.
When Air Conditioners Freeze Up, Why Is That?
The most common causes of ice on indoor air conditioners are listed below.
· Lack of Ventilation:
The evaporator coil is a component of your home air conditioning system. This metal coil is extremely chilling since the refrigerant is circulating through it. Indoor air is cooled when it is blown over a cold coil, transferring its heat and moisture to the coil.
So, if the evaporator coil has too little airflow, what happens? When the warm air inside your home isn’t able to warm up the chilly coil, ice might form on the metal.
· Low Refrigerant Level:
It’s possible that your air conditioner doesn’t have enough refrigerant because of a leak or because the technician who installed the unit didn’t charge the refrigerant properly.
When the refrigerant in your air conditioner is low, the pressure in the system drops, and the refrigerant itself gets much colder than normal. Because the refrigerant chills the coil to an extremely low temperature, condensation from the indoor air freezes as it forms on the coil. As more ice accumulates, airflow through the coil is impeded, worsening the icing problem.
· Dirty Coil:
The coil itself can sometimes be a problem. The evaporator coil in your interior air conditioner is no exception to the rule that dust and dirt will accumulate if you don’t clean it regularly.
Sometimes, dirt builds up on a coil to the point that it prevents heat from reaching the refrigerant inside. So, the already cold coil will get even colder as the condensation builds up and eventually freezes.
If My Air Conditioner Freezes Up, What Should I Do?
It’s possible that you can defrost the air conditioner on your own. If you suspect a frozen evaporator coil, you shouldn’t use the air conditioner because doing so could harm or even destroy the compressor. To begin the melting procedure on the coils, which may require up to 24 hours, you need to go to your electrical breaker box and switch off the switch that supplies power to your air conditioner.
Turning off the air conditioner and turning on the fan can assist in defrosting the evaporator coils. Attempting to remove the ice by hand is not recommended because it increases the risk of breaking parts. Once the condenser and coils have defrosted, you should drain any water that has collected around them.
