AC Services in Festus, MO

You want to be able to depend on your HVAC system, and especially your air conditioner, any time of the day. Summers in Festus, MO can be very warm. The last thing you want is to turn on your air conditioner and find yourself in the heat because your air conditioner has frozen up.

What Does It Mean for an Air Conditioner to Freeze?

A frozen air conditioner is a more serious problem than most people think. If your air conditioner is covered in a thin layer of ice, it is considered to be frozen up. You might see frost collecting on the refrigerant lines. You might see a very thin layer of ice or thick opaque ice covering the unit. There are several reasons why this happens, and there are also several steps that an air conditioning repair technician can take to address the problem.

Low Airflow

One of the primary reasons you have a frozen air conditioning system is that there is not enough airflow. If you are experiencing this issue, the warm air from your home is struggling to flow over the evaporator coils. This leads to condensation.

Throughout this process, the compressor continues to run, and the condensation that builds up becomes ice. One of the things HVAC professionals will check for when attempting to repair an iced-over air conditioner is blockages or leaks in the ductwork. Once the issue is corrected, it improves airflow, preventing ice from forming in the future.

Dirty Air Filter

It is recommended that you have your air filters changed in compliance with the manufacturer’s specifications. Failure to replace or clean a dirty air filter can affect airflow. Ice will eventually form when the air filter blocks warm air from reaching the evaporator coil. In addition to preventing ice from forming on the components of your air conditioner, changing your air filter helps improve your home’s indoor air quality. It is one of the most important maintenance processes for maintaining your air conditioner and your entire HVAC system.

Low Refrigerant

Low refrigerant levels can lead to your HVAC unit freezing up. When refrigerant gets too low, your evaporator and condenser coils can become too cold. This will lead to them freezing. Replacing and checking refrigerant levels is not a do-it-yourself project. You will need to work with an HVAC professional to check refrigerant levels and to repair whatever damage led to the leak. A damaged compressor could be a very expensive repair. Depending on the age of your HVAC unit, you may opt to purchase a new air conditioner instead of investing in costly repairs that may only be a stopgap.

Blower Fan Issues

A damaged blower fan may cause insufficient airflow, leading to the freezing up of your coils. It’s challenging for a homeowner to independently assess the proper functioning of the blower fan. It’s advisable to contact a professional HVAC technician to inspect the blower fan and determine the necessary course of action to restore your HVAC system’s proper functionality.

Clogged Condensate Drain Line

The air conditioning system in your Festus, MO home operates by extracting heat from the inside and transferring it outside. The moisture in your home’s air generates condensation, which then drains through the condensate drain line.

Over time, the condensate drain line can accumulate dirt due to debris, mold, or mildew growth. A clog in the condensate drain line can cause the drip tray to overflow with excess water from the air’s moisture, leading to the freezing of the evaporator coil. The HVAC professionals at Bone Heating & Cooling possess the skills and knowledge to address this issue. Among the steps we take is flushing and clearing your condensate drain line, ensuring everything operates as designed. Additionally, scheduling routine HVAC maintenance can help prevent such issues from occurring in the first place.

Malfunctioning Thermostat

There could be an issue with the thermostat or room sensors that leads to your HVAC system overworking. The controls for your HVAC system control the humidity, cooling, and heating in your home. A faulty thermostat could activate your air conditioner even though the temperatures outside are low. If your air conditioner runs constantly, the condenser coils might freeze up, impacting the function of your entire HVAC system. If that’s the case, you will need to get the thermostat repaired or replaced by an HVAC professional.
