Can I Repair My Own Frozen Heat Pump?

If you’ve lately detected your heat pump device freezing, your machine might be in danger. While your heat pump unit is responsible for delivering cool or hot air to your home according to the weather conditions, your machine freezing up is not a good sign.

In numerous circumstances, a frozen heat pump device will no longer offer suitable airflow. Furthermore, when this occurs, you may notice either excessively hot or excessively cold air blasting out of your heat pump. If you are looking for an HVAC contractor in Clermont, FL you can trust, contact the experts at Enginair Air & Refrigeration.

Keep reading below to learn more about the primary reasons for a heat pump freezing and how you can defrost your heat pump.

What are the Prominent Reasons Behind a Frozen Heat Pump?

Heat pump devices can freeze when heat from the external air is shifted to refrigerant and excessive moisture from the air stockpiles onto your machine’s coils. On cold days, the same dampness might squeeze into layers on your machine; if this occurs, it makes it more challenging for your machine to function effectively. Here are some reasons for a frozen heat pump.

  • Increased Moisture Content

Your heat pump device lowers the air temperature as it discharges from the compressor into your house. However, if this air is damp and includes a high dampness level, lowering the temperature will push the water to crystallize and form ice. It will stockpile on your evaporator coils, and you will detect no more airflow shooting from your heat pump.

  • Not Sufficient Airflow

The airflow is the principal component of a heat pump unit. In addition, if the air flows too much, your heat pump device will blast out hot air because it does not have sufficient time or refrigerant to chill the atmosphere.

On the other hand, if the airflow is excessively low, the air will take less time to cool down, which will cause a condensation effect, and you will detect ice on the exterior. Insufficient airflow can be due to clogged air filters, damaged motors, or even inappropriate compressor placement.

  • Clogged Coils

The coils may get blocked if dirt and dust particles have infiltrated your machine’s refrigerant coil. These coils are generally surrounded by moist air. When they’re blocked, the air encircling them gets sufficient time to freeze and form ice. It will further connect with humidity and end in ice accumulation.

How to Fix a Frozen Heat Pump Device Yourself?

Luckily, most heat pump devices contain a defrosting process that starts before the ice accumulates excessively. Furthermore, numerous heating and cooling contractors are made to extract the cool air from home and control things from freezing, by entering the defrost mode when it turns excessively cold.

In addition, heat pumps are reverse air conditioning appliances since they generate heat rather than chill air by reversing the cycle. Some heat pumps employ this method to deliver hot air during the defrost revolution to thaw ice accumulation on the outdoor device. Until the revolution is completed, no heat will generally be released indoors when your outside machine works in defrost mode. Below is a comprehensive process to thaw your heat pump device.

  • Turn off your heat pump immediately. It can gravely damage itself if it attempts to run for an extended time.

  • If ice accumulates on the interior coils, try to scrape it off. To perform this, avoid using sharp or heavy tools or call our HVAC contractor in Clermont, FL, if a brush won’t extract it.

  • Inspect the external unit for easy reasons such as a blocked air filter, snow accumulation, or plant matter.
