Even during the fall in Clemson, SC, you can experience some warm days. But late in the season, the nights start to feel chilly. Therefore, you need your heat pump not to freeze so that it can keep you comfortable. Here are some reasons your heat pump could freeze:
Restricted Airflow
When your filter clogs, air won’t flow through the system the way it should. That causes the pressure inside the system to fall, which will affect the flow of coolant through the coil. When this happens, ice can form around it.
Dirty Coil
Dirt on the coil absorbs moisture from the air. When there’s dirt on the coil, it also generally collects in the air filter. When you put the extra moisture together with poor airflow, ice forming within the system is the result.
Low Refrigerant
A refrigerant leak will cause a precipitous drop in your system’s internal pressure, which will then result in the system’s components freezing. When your refrigerant is running low, you’ll need a service call from one of our professional service technicians. Not only will we have to top off the coolant, but we’ll also have to find the leak and fix it.
Obstructions On the Return Vents
As you can see, many of the things that cause ice to form both on and within your heat pump have to do with reducing the pressure in the system. If you’ve covered the air intake vents within your home, the system won’t be able to maintain the right pressure, which will then result in ice formation. Uncovering the vents should fix the problem as long as nothing else is amiss.
