Why do acs freeze




















Our trained professionals inspect your ductwork and offer redesign solutions, if necessary. If there is a clog, like nesting material or other signs of pests, we clear obstructions blocking proper airflow. The condensate lines drain excess moisture from your HVAC system. With frozen water in your lines, you could be left with frozen HVAC coils as well. Over time, evaporator coils attract dust, hair, grime and form a clog. If there is moisture trapped inside the clog, the moisture freezes and the coils freeze as well.

Frozen coils restrict airflow. This causes your system to struggle or not work at all. The best prevention for frozen HVAC coils is to schedule preventive maintenance. Save money, avoid AC repairs, breakdowns and a frozen HVAC system in the future with routine air conditioning service. Related blog: How a Condensate Pan Works. A proactive and preventive mindset saves you money throughout the year on your energy bill and keeps your air conditioning running well.

Make it even easier with membership in one of our service plans. We offer plans at three different levels to fit any budget. Step Two: Dry the Coils Once the ice is gone, dry the evaporator coils. Filter changes vary based on factors, such as: The type of filter you have Presence of children or pets in the home The season and if you live in a high-pollen count area Whether a household member smokes A household member lives with asthma, allergies, COPD or congestive heart conditions If you frequently run your system During regular HVAC maintenance , KS Services professionals inspect your filter and will change it for you if a new one is available.

Despite the ironic happening of an AC freeze in the summertime, air conditioners freezing up is something that happens a lot. Not many homeowners are equipped with the knowledge and understanding about air conditioners to prevent this problem on their own. A sure sign is to check the supply registers. Is it warm? Open the panel and check for ice. However, seeing ice is pretty-well a guarantee that your AC is frozen. First, we must understand that temperature is how much energy a molecule has.

The same works in reverse, cold air is comprised of low energy molecules. When it is compressed, the molecules get excited and heat up. The point of an air conditioner is to expand the refrigerant inside the evaporator coil so that it cools down, so when it leaves the air conditioner, it cools the air inside your home and effectively removes the hot air from inside the house. However, if something in the air conditioner malfunctions, the whole system gets disrupted. This causes the evaporator coil to allow the refrigerant to cool too much, causing it to fall below freezing and ice over.

So, how can you prevent something in the cooling equation from going terribly wrong? Closed supply registers: Shutting supply registers in unoccupied rooms is a technique for saving money and energy.

However, if you close too many, it could end up costing you more if the air conditioner freezes up. Insufficient fan speed: The fan must blow fast enough to keep the proper amount of air blowing over the evaporator coil. A technician can increase the fan speed and do away with what causes an air conditioner to freeze. This wastes energy and money while possibly causing your air conditioner to freeze. Have the thermostat checked out to solve the issue.

Drainage problems: When hot, humid air blows across the evaporator coil, the coil removes heat as well as moisture from the air. In humid climates such as Georgia, a lot of water vapor is turned into condensation within the air conditioner. Under normal circumstances, the water drips into a pan and out a floor drain. If something blocks the drain, the backed-up water freezes all the way back to the evaporator coil.
