Understanding Your Air Source Heat Pump:

Before we just jump into the how-tos on self-maintaining your heat pump, it’s super important to understand how the heat pump itself operates. Essentially, your air source heat pump works by transferring heat from the outside air into your home, and vice versa to cool it in the warmer months. It’s wild to know that there’s heat outside, even when temps are in the negatives, but it’s true! There are multiple parts that work to make all of this happen in your heat pump, including a compressor, condenser, evaporator, and refrigerant lines.

Tips for Heat Pump Self-Maintenance:

1 – Regularly Clean or Replace Air Filters:

One of the simplest yet most important maintenance tasks is cleaning or replacing your heat pump’s air filters. Clogged filters restrict airflow, reducing the heat pump’s efficiency and potentially leading to system malfunctions. Check your filters monthly and clean or replace them as needed, especially during peak usage seasons. Want to see filter cleaning in action?

2 – Keep Outdoor Unit Clear:

The outdoor unit of your heat pump can accumulate dirt, debris, leaves, and even snow depending on the season. Make sure that the area around your heat pump’s outdoor unit remains clear to allow proper airflow. Trim back any growth from bushes, trees, or grass, and be sure to remove any obstructions that could block airflow to the unit.

3 – Inspect and Clean Coils:

Both your heat pump’s outdoor condenser coil and indoor evaporator coil can collect dirt and dust over time, hindering heat transfer. By periodically inspecting these coils and cleaning them, you’ll ensure efficient performance. For the outdoor unit, you can use a hose. Make sure you’re gentle to avoid damaging the fins. For the indoor unit, use a soft brush or vacuum cleaner.

4 – Check and Clean Drainage System:

A clogged condensate drain on your heat pump can cause water leakage or potentially even water damage to your home, and that’s no good! Inspect the condensate drain regularly and be sure to remove any obstructions using a vacuum or a mixture of water and mild detergent. Ensuring proper drainage prevents future issues.

5 – Monitor Refrigerant Levels:

While refrigerant leaks are very uncommon, it’s essential to monitor the refrigerant levels periodically to be sure nothing fishy’s happening with your heat pump. Low refrigerant levels may indicate a leak or other issues that require professional attention. If you notice a significant decrease in cooling or heating efficiency, contact the team at Elephant Energy to inspect and recharge the refrigerant as needed.

6 – Test Thermostat and Controls:

Regularly test your thermostat and heat pump controls to ensure they’re functioning correctly. Sometimes, it can be as simple as replacing the batteries in your thermostat if you’re having issues. You’ll also want to ensure that the settings are appropriate for your climate-friendly home’s needs.

7 – Lubricate Moving Parts:

Some components of your air source heat pump, such as fan motors and bearings, may require lubrication to reduce friction and ensure smooth operation. Refer to your owner’s manual for guidance on lubrication intervals and the type of lubricant to use.
