How to Prevent Frost & Ice
Buildup on your Heat Pump
Heat pumps are an excellent way to heat and cool your home efficiently, but they are susceptible to frost and ice buildup, leading to reduced efficiency and increased energy costs. We will outline steps and provide tips to help prevent frost and ice buildup.
Causes of Frost and Ice Buildup on Heat Pumps
Several factors cause frost and ice buildup on heat pumps and understanding how they work is essential in preventing this.
The most common cause of frost and ice buildup on heat pumps is when temperatures are too low. When heat pumps operate below freezing, they need energy to heat the air around them to keep them from freezing. If the temperature drops too low, the heat pump will not be able to keep up, and frost and ice will start to accumulate on the unit.
Another cause of frost and ice buildup on heat pumps is when the outdoor temperature is warmer than the indoor temperature. The heat pump takes warm air from outside, cooling it down to the desired temperature. This can cause frost and ice to form outside the heat pump, as the air inside is colder than the outside.
The third most common cause of frost and ice buildup on heat pumps is when the unit is not correctly insulated. Heat pumps must be appropriately insulated to keep warm air from escaping and cold air from entering. If the insulation is inadequate, it can cause the heat pump to work harder to maintain the desired temperature, resulting in frost and ice buildup.

Tips to Prevent Frost and Ice Buildup on Heat Pumps
Keep the Area Around Your Heat Pump Clear
Keeping the area around your heat pump clear is an essential step in preventing frost and ice buildup and maintaining the efficiency of your heat pump. Debris, such as leaves, dirt, and grass clippings, can block the airflow to the heat pump’s outdoor unit, causing it to overheat or freeze. In addition, vegetation such as bushes, trees, or vines can grow too close to the unit, obstructing proper airflow.Regularly remove debris or accumulated vegetation near the unit to keep the area around your heat pump clear. Use a rake or broom to sweep away leaves, grass clippings, and other debris around the unit.
Install a Protective Cover
Installing a protective cover is another effective way to prevent frost and ice buildup on your heat pump. A specially designed cover can protect the heat pump’s outdoor unit from harsh weather conditions, such as snow, ice, and sleet, which can cause moisture to accumulate and freeze on the unit.When choosing a protective cover, make sure to select one that is specifically designed for your heat pump model. A well-fitting cover will help protect the heat pump while allowing for proper ventilation and airflow.
Consider Installing a Defrost Control
Installing a defrost control is another effective way to prevent frost and ice buildup on your heat pump. A defrost control is a device that automatically detects when the outdoor unit is experiencing frost or ice buildup and initiates a defrost cycle to remove it.During a defrost cycle, the heat pump will temporarily switch into cooling mode, causing the outdoor unit’s coils to warm up and melt any frost or ice buildup. This cycle typically lasts for a few minutes and will automatically switch back to heating mode once the buildup is removed.
You should consult a licensed HVAC technician to install a defrost control. They will be able to assess your heat pump’s specific needs and recommend a defrost control that is compatible with your system.
