Ac Organisation Freezing Up: How You Can Gear up It The First Try

Is your air conditioner freezing up? Information technology can be surprising to see a chunk of ice sitting on your outdoor AC system, specially in the middle of summer. Merely sometimes you tin can't even see the ice on the exterior of the unit.

While you lot may call up something similar this during the hottest days of the year is incommunicable, an air conditioning unit freezing in the summertime is something that happens oftentimes.

If you lot fear you're experiencing a frozen air conditioner, continue reading to hear what causes it, what to do if you're experiencing a frozen AC system, and how you can foreclose or keep something similar this from happening once more.

What Causes an Air Conditioner to Freeze?

To understand how an Ac unit tin start freezing upwards, you lot first need to empathise the basics of how cardinal air-conditioning systems work. And it all starts with your evaporator coils.

This fundamental air-conditioning component is full of extremely cold refrigerant. When the coils are activated, the refrigerant will need warm air to blow across them. This cools your air and keeps the coils at a warm enough temperature that they practice not freeze. The indoor whorl removes heat from the inside air, and and so will transfer it using the refrigerant to the outdoor gyre which pushes the rut to the outside. The organization is really pulling estrus from your indoor air and transferring the extra heat outside. This is why if you lot ever put your hand over the fan running on your outdoor unit of measurement the air feels noticeably hot.

However, if something in the air conditioner malfunctions, the whole system gets disrupted. If something prohibits the warm air from blowing over the coils, this causes the evaporator coil to permit the refrigerant to absurd also much, causing it to fall below freezing and water ice over. Or if the refrigerant pressure is wrong inside the coils, then your system'due south coils can get too cold and can rapidly freeze up. And that can leave you with a frozen Air-conditioning.

What To Do if Yous Find Water ice on your Outdoor Air conditioning Unit

If you believe you are experiencing a frozen outdoor AC, there are some simple steps y'all can accept in order to get things back upwardly and running once again.

Step one) Thaw

Make every effort to avert using the AC while the evaporator coils are frozen. Running the AC with frozen coils strains the AC compressor. Go to your electrical breaker and turn off the power to your Ac unit. This will continue the system from freezing upwards even more and begin to let the ice thaw. The AC compressor is the about expensive component in your air conditioning unit. The strain could impairment this incredibly valuable office and set you up for a costly air-conditioning repair service call.

Even if it's blistering hot exterior, it could have a whole day for the ice to completely thaw away. Don't be tempted to break up the water ice with a heavy object or sharp tool. This easily damages components so much so you'll demand to replace multiple parts, which tin add together up financially, or worse be forced to replace the arrangement altogether.

Pace two) Dry

Once the water ice is completely melted abroad, yous need to dry the evaporator coils. You can use some paper towels, or let the parts dry out in the sun if in direct sunlight. Restore the power to your system and turn the blower on. Run inside and set your thermostat to only run the blower or fan, depending on the model of the thermostat you have. This circulates air around and through the coils to dry them apace. Once the coils are dried thoroughly, your organisation should resume operating normally.

Now that yous know what to exercise if you e'er encounter a frozen air conditioner, permit's talk nearly how you tin can keep this from happening.

How to Prevent a Frozen Air conditioning System

It'southward important to recognize this is preventable. Take these measures to go on your HVAC system from freezing over.

Change Your Air Filter

The leading cause of a frozen HVAC system is a dirty air filter. The air filter cleans the air circulated into your home. Equally your AC system runs throughout the summer, the filter catches dirt, pollen, grit, and other allergens. This tin can restrict airflow and could atomic number 82 the HVAC coils to freeze. Typically, we recommend you cheque your filter monthly. Change it as needed. For most folks, this is ane to every three months. Filter changes vary based on factors, such as:

• The type of filter y'all have
• If yous have children or pets in the dwelling house

This causes your system to work harder without a style to release the cooled or heated air.

Some other good exercise is to walk around your abode and check that indoor air vents and registers are clear from any obstructions. If you fear you lot're experiencing weak airflow through your vents, your ductwork may be to blame. In some cases, the ductwork is installed well but the wrong size for your business firm or the capacity. Or there's a duct leak or a section of ductwork has collapsed somewhere within your walls.

Clean Evaporator Coils

The condensate lines drain excess wet from your HVAC system. If there's a clog in the line, the water becomes stuck and the excess h2o freezes. And that frozen h2o in your lines could leave you with frozen HVAC coils besides. This causes your system to struggle or not work at all.

Check the Forecast
