Understanding the Science Behind AC Unit Freezing Up
Air conditioning systems are a modern marvel that has become an essential part of our lives. They keep us cool and comfortable during hot summer days, but sometimes these systems can malfunction, leading to issues like AC unit freezing up. In this section, we will delve into the science behind air conditioning systems and understand how they work.
Air Conditioning System and How It Works
An air conditioning system consists of four main components: a compressor, a condenser, an expansion valve, and an evaporator. The compressor compresses the refrigerant gas and sends it to the condenser where it releases heat to the outside environment. The refrigerant then moves through the expansion valve where its pressure is reduced, causing it to cool down rapidly. This cooled refrigerant then flows through the evaporator coil in your home’s air handler unit.
Cold Coil and Its Role in AC Unit
The evaporator coil is responsible for cooling down warm air that is circulated in your home’s ductwork by absorbing heat from it. As warm air passes over the cold coil surface, moisture in the air condenses on it, creating water droplets that drain away via a drip pan or drain line. The cooled dry air then gets blown back into your home via supply vents.
Factors Affecting Airflow and Fan Speed
Several factors can affect airflow and fan speed inside your mobile home ac unit system which ultimately leads to freezing up of ac coils. Dirty filters can restrict airflow; low refrigerant levels can cause coils to freeze; closed vents or registers can lead to improper airflow distribution; blocked return grilles can also reduce airflow; dirty blower wheels or evaporator coils can decrease fan speed.

Thomson Effect and Its Impact on AC Coils
The Thomson effect states that when current flows through two dissimilar metals joined at two points (called thermocouples), there is a temperature difference between the two junctions. This effect is used in thermoelectric cooling devices like air conditioners, where a thermocouple is placed at the evaporator coil’s exit point. The temperature difference causes heat to be absorbed from the surrounding air, leading to cooling.
Common Reasons Why Mobile Home AC Units Freeze Up
If you’ve ever experienced your air conditioner freezing up, you know how frustrating it can be. Not only does it prevent your AC from producing cool air, but it can also damage the unit over time. In this section, we’ll explore some of the common reasons why AC units freeze up and what you can do to prevent it.
Fix Frozen Mobile Home AC: Dirty Air Filters
One of the most common causes of a frozen air conditioner is dirty air filters. When your filters are clogged with dirt and debris, they restrict airflow to the evaporator coil. This causes the coil to become too cold and freeze up. To prevent this from happening, it’s important to change or clean your air filters regularly. Depending on the type of filter you have, you may need to replace it every 1-3 months.
Low Refrigerant Levels
Another reason why your AC unit may be freezing up is due to low refrigerant levels in the system. Refrigerant is responsible for absorbing heat from inside your home and transferring it outside. When there isn’t enough refrigerant in the system, it can cause the evaporator coil to become too cold and freeze up. If you suspect that low refrigerant levels are causing your AC unit to freeze up, contact a professional HVAC technician to inspect and recharge your system.

Poor airflow due to blocked vents or ducts can also cause an AC unit to freeze up. When there isn’t enough warm air flowing over the evaporator coil, it can cause ice buildup and eventually lead to a frozen air conditioner. To improve airflow in your home, make sure that all vents are open and unblocked by furniture or other objects.
In addition to these common causes, there are other factors that can contribute to an AC unit freezing up:
Thermostat settings: If your thermostat is set too low or if there’s a malfunction, it can cause the AC to run excessively and freeze up.
Fan problems: A malfunctioning fan can prevent warm air from flowing over the evaporator coil, causing it to freeze up.
Dirty coils: Over time, dirt and debris can accumulate on the evaporator and condenser coils, reducing their efficiency and causing ice buildup.
To prevent your AC unit from freezing up, it’s important to schedule regular maintenance with a professional HVAC technician. They can inspect your system for any potential issues and perform necessary repairs or cleanings.
Signs that Your Mobile Home AC Unit is About to Freeze Up
If you live in a mobile home, you know how important it is to have a working air conditioning unit. It keeps you cool and comfortable during the hottest days of the year. However, if your unit freezes up, it can cause serious problems. Here are some signs that your mobile home AC unit is about to freeze up.
Frost buildup on the unit is a clear sign that it’s about to freeze up.
If you notice frost buildup on your AC unit, this is a clear indication that something is wrong. Frost buildup occurs when there is moisture in the air and the temperature drops below freezing. When this happens, the moisture in the air condenses on your AC unit and freezes.
To prevent frost buildup from occurring, make sure that your filters are clean and free of debris. Dirty filters can restrict airflow and cause moisture to build up on your AC unit.
Water damage caused by leaks can also indicate that your AC unit is at risk of freezing up.
Leaky pipes or connections can cause water damage around your AC unit. If you notice water damage around your unit, this could be an indication that there’s a leak somewhere in your system. Leaks not only waste water but also reduce the efficiency of your system by allowing cold air to escape.
If you suspect that there’s a leak in your system, don’t hesitate to call an HVAC professional. They’ll be able to diagnose the problem and fix it before any serious damage occurs.
