As fall progresses in Sugar Hill, GA, temperatures will drop into the 40s. A frozen heat pump will directly affect your ability to stay warm at home. There are a few common reasons as to why your heat pump might freeze.
1. Clogged Air Filter
When the heat pump has low airflow, the evaporator coils can freeze. The most common cause of low airflow is a clogged filter, so you should change it at least every three months. If changing the filter does not fix the airflow issue, you’ll need heat pump service from a professional technician.
2. Low Refrigerant
Low refrigerant is another common cause of frozen evaporator coils. When it’s low, the refrigerant can’t absorb enough heat. You should always call a professional to fix low refrigerant.
3. The Coil Is Dirty
When excessive dirt collects on the coil, it prevents the refrigerant from absorbing heat. Water can then collect on the evaporator coil, that moisture can then freeze.
4. You’ve Blocked Your System’s Return Vents
Your heat pump draws air from inside your house to heat it and then pushes it back into your home. Blocking those vents will reduce the pressure in the system, which might then result in ice buildup. Fortunately, this is easily fixable by simply removing the blockages from the return vents.
