Winter brings many hazards, one of which is freezing temperatures. Unfortunately, this can be a major problem for heat pumps that are not well maintained or properly prepared for the winter season. Fortunately, there are several measures you can take to prevent your heat pump from freezing up this winter. In this article, we’ll discuss 10 tips for preventing your heat pump from freezing in cold weather.
1) Make sure the outside unit is clean and clear of debris: Before winter arrives it’s important to make sure that the area around the outside air conditioning unit is free of leaves, sticks, and other debris. This will help ensure that any airflow over the coils isn’t blocked and impair performance.
2) Check refrigerant levels: Refrigerant is an important part of a heat pump’s performance, and low levels can cause freezing. Make sure that the refrigerant level in your system is correct, and if not get it corrected by a professional before winter arrives.
3) Check for air leaks: Air leaks around windows, doors, and other openings in the house can have a negative effect on the efficiency of your heat pump. Take time to seal any air leaks you find before winter comes so that cold outside air won’t flow into the home.
4) Make sure coils are clean: Keeping the indoor evaporator coil and outdoor condenser coils clean can help improve performance and reduce freezing potential. A professional technician should be able to inspect and clean the coils if needed.
5) Install a thermal expansion valve: The entire refrigeration system in your heat pump will be much more efficient if you install a thermal expansion valve. This is an inexpensive part that can help prevent problems with freezing and even improve efficiency.
6) Check thermostat settings: Make sure that your thermostat is set to the right temperature for winter weather. A setting that’s too low can cause freezing, so make sure it’s set no lower than 68 degrees Fahrenheit (20 degrees Celsius).
7) Check fan speed: If your heat pump has adjustable fan speeds, make sure they’re set appropriately for cold temperatures. Slower speeds are better for cooler weather since they can help keep the heat pump from running too hot.
8) Install a timer switch: Having a timer switch installed for your outdoor unit can help prevent freeze-ups. This device will turn off the unit if it’s been idle for more than an hour, preventing prolonged freezing situations.
9) Insulate outside pipes and ducts: Any exposed pipes or ducts on the outside of your home should be insulated to protect them against cold temperatures. It can also be helpful to wrap any exposed pipes with insulation tape as well.
10) Keep air filters clean: Lastly, replacing dirty air filters regularly will help improve performance and reduce the likelihood of freezing up in cold weather. Make sure that you change out the filter at least every 90 days or sooner if necessary.
Following these tips can help ensure that your heat pump runs smoothly this winter and avoids any potential freezing issues. However, if you notice any problems or suspect a freeze-up, contact a professional technician to inspect your system and make any needed repairs. With proper maintenance and care, you can keep your heat pump running efficiently all season long.
