It’s not a good moment when an HVAC unit has turned into a lump of ice. However, in the countless calls they receive, HVAC companies in West Virginia see this issue quite frequently. A frozen AC leads to diminished performance and premature failure, which can be costly. Here, business owners will learn why their units freeze and how they can keep it from happening.
Why is the Unit Frozen?
A frozen HVAC unit isn’t indicative of a single problem; there may be more than one reason for the issue, but they all start when the evaporator coil freezes due to a refrigerant imbalance. When the unit is used, the compressor moves refrigerant through these coils, absorbing heat as the air passes by. Just as ice can’t get through plumbing pipes, frozen refrigerant can’t move heat out of the home. If the unit isn’t as efficient as it once was or utility bills start to rise, it may be time to take freeze protection measures.
Reasons for Evaporator Coil Freezes
A dirty filter is the most common problem. This is why AC technicians stress the importance of frequent changes. It’s the easiest way to maintain a system and it’s also the most crucial. A failed fan motor may also be to blame. The fan moves air over the coils, and if it’s not doing its job, the system won’t cool the home. Finally, the unit may be too large. Where AC units are concerned, size does matter. Too-large units short-cycle, and they don’t move enough air. If the unit is experiencing one or more of these issues, the use of glycol may help keep things cool. Businesses can call for HVAC freeze protection service and repair.
How to Prevent HVAC Unit Freeze-Over
While HVAC freeze-overs are problematic, there are a few ways to prevent them, such as regular maintenance. Just as people get annual physicals, their HVAC systems need yearly maintenance. These freeze prevention visits are surprisingly affordable and they prevent expensive issues by maintaining and sometimes replacing system components.
Another way to avoid such an issue is by frequent filter changes. HVAC filters should be changed every 30 to 90 days, depending on the environment. Dog and cat owners typically need to change them more often because of pet dander and coat shedding. Lastly, ensuring that the unit is properly sized. A local HVAC installer will help a business owner make an informed decision. First, they’ll use their experience, as well as load calculations, to determine the right size unit for the home. They will also help customers choose models that align with their priorities, such as noise levels, advanced features, and energy efficiency.
