Keeping Your HVAC System In Great Condition

There aren't many things more frustrating than an air conditioning that refuses to run. A hot, muggy home can make your space incredibly uncomfortable, which is why I have always focused on maintaining my air conditioning system. Unfortunately, I still run into problems from time to time and I am sure that all of you do, which is one of the reasons I decided to build this website. Check out these posts for more information about keeping your system working beautifully, even if you aren't naturally good at fixing things. You never know, making the right changes could dramatically improve your summertime experience.

Reasons Your AC Unit Is Freezing

Herbert Franklin

When an air conditioner freezes up, it can result in many issues, such as reduced effectiveness and an inflated electricity bill. This can be a frustrating problem for homeowners, but fortunately, typical causes of AC freezing can often be avoided with proper upkeep and repairs.

Poor Airflow

Poor airflow can contribute to the AC unit freezing. When warm air cannot flow over the evaporator coil, it can cause a buildup of ice, ultimately resulting in the system shutting down altogether. Dirty air filters and a faulty blower motor can contribute to this problem. Dirty air filters constrict the flow of air that can move through and can be easily remedied by replacing or cleaning them regularly. Similarly, blocked ducts or vents can restrict air flow, and you must clear them to allow for proper circulation. A faulty blower motor is another common cause of poor airflow, and a professional should be hired to repair these mechanical issues.

Low Refrigerant Levels

Low refrigerant levels are a frequent cause of AC freezing. When the evaporator coil has a refrigerant leak, the coil's surface can be excessively cooled. This can lead to condensation freezing and causing ice to accumulate. Repairing the leak may require the assistance of a professional familiar with the equipment and techniques for locating leaks. This may involve pressurizing the system or conducting a comprehensive visual inspection of the coils and connections.

Thermostat Issues

Thermostat problems can also cause AC freezing. When the thermostat is not functioning properly, it can cause the system to run too frequently or for too long. This can lead result in a buildup of ice on the evaporator coil. If the thermostat is the reason for AC freezing, it may be necessary to replace the malfunctioning temperature sensors or adjust the thermostat's settings. Leaving this work for a professional can be a convenient option.

Dirty Evaporator Coil

A dirty evaporator coil is another issue that could play a role in the AC unit freezing. This is due to dirty coils reducing heat absorption and increasing ice buildup. Common causes of dirty evaporator coils include a lack of regular maintenance or inadequate air filtration. Regularly cleaning the AC unit is one option for limiting the risk of this problem occurring for the system. Luckily, there are coil cleaning products that you can use to easily remove dirt and grime that has gathered on them. When using these products, leave the cleaning agent on the coils for several minutes before rinsing them. This can give the cleaning agent enough time to loosen and break down the grime.
