AC Freezing Up? 4 Reasons Why
Most people don’t see it as a surprise to find their AC cold. But the same can’t be said for those who find frost on theirs. At times, frost build up is so overwhelming that full blocks of ice form on the aircon. Failure to deal with such a situation can be detrimental. You can end up incurring other burdens such as water damage or an expensive AC repair. Luckily there are remedies to the situation if detected at an early stage.
The first and most straightforward thing to do when fixing your frozen AC is turning the system off in an attempt to stop the frosting. But if the AC was initially cooling, the frost will continue to form. In such a situation, you should turn on your thermostat and set it to heat. This will help speed up the thawing process. When thawing, be keen on the water levels in the unit. If the drain pan overflows, you could experience water damage from your AC. Below are some of the main reasons why your AC might freeze up.
1. Low Refrigerant
Air conditioners use chlorodifluoromethane also known as R22 to cool. This chemical displays different physical properties when subjected to various pressure stages. In a typical working AC, R22 passes through the lines at a temp that favours condensation. In case anything happens and the rhythm of pressure is disrupted in your AC, the R22 starts acting differently to adapt to the pressure changes. In such a situation, warm moist air moving from your house over the evaporator begins to condense and freezes on the coils thus forming ice on them. Failure to fix the issue can lead to potential water damage.
2. Poor Airflow
Proper airflow is essential if you are to avoid freezing in your AC. If the airflow is weak, the AC will not get sufficient air, which provides heat as warm air moves from your house. This will consequentially cause condensation on the coils, thus forming ice.
3. Dirty Coils
Dirty coils result in freezing since the layer of dirt laying on the coils prevents dehumidification. This leads to the formation of frost and ice on the coils. In such conditions, the evaporator coils freeze, which in turn causes condensation. The result is catastrophic to the drip pan, which collects the condensation droplets and ends up overflowing. Additionally, the coils get waterlogged and freeze.
4. Damaged Blower
The measure of how effective your AC creates and delivers fresh air relies on its ability to maintain the right balance of airflow and air pressure. This is achieved using a blow fan in the AC. When the blower is damaged, airflow inside the air handler will be affected. Too much condensation builds up on the coils, and the water droplets do not drain as they should. Without the proper flow of hot air, the refrigerant line would freeze and potentially spread to the condenser unit.

Why you need an electrician to install air conditioning systems
When people think about installing an air conditioning unit in their home, they are often thinking about window units that can be easily set up and plugged in. These are going to work with any outlet that you have, and as long as you know how to properly seal off the window, you are going to have cool air within about 30 minutes. However, if you want something much larger such as a central air conditioning unit, this is going to take a much higher level of expertise. You will no longer be able to simply pull the unit out of the box and use it. You will need to have an electrician, or someone with experience with installing electrical components, to help you with this type of AC system. Here are the many reasons why you should consider working with an electrician if you would like to have a central AC unit installed.
Why Would You Need An Electrician For This?
If you are working with an HVAC company that does AC installs all the time, they will have the electrical background and experience that will be necessary. They do this on a regular basis, and can easily hook up all of the wiring that will connect to your main electrical system. There needs to be a separate circuit breaker for the air conditioning unit as it will use a lot of power. There is always the possibility that something could go wrong, which is why there needs to be a separate circuit breaker for these machines that draw a lot of power.
Reasons That Most People Cannot Do This Themselves
There are so many reasons why an electrician will be necessary. First of all, you are working with electrical power. You are not going to be using one of your outlets. They must remove the front panel, take off the cover, and connect wires to the screw terminals. The wires must be the appropriate size, and they must connect with the circuit breaker so that it can get the power that it needs. Additionally, if you have any live wires, there is the potential for hurting yourself in a substantial way. Therefore, not only will they know what to do but they will also know how to install this in the safest possible way. They work with electrical wires all the time and will understand how to quickly attach everything so that your AC unit will be fully functional.
If you have not installed one of these before, it’s always recommended that you contact a professional electrician to help you. You may have an HVAC company come out to do this, but your other option is to use an electrician to help you install what you have already purchased. By doing so, you can feel confident that it will work properly, and that you will never be in any danger trying to do this yourself. You can find many electricians in your local area such as Electrician St Kilda that will understand how to install an AC unit in your home so that you can keep your family cool this summer.[Top]
