Guide To Heat Pump Servicing & Maintenance

Don't waste power on an inefficient Heat Pump! Follow the steps outlined in EES's guide to heat pump servicing and maintenance to keep your heat pump running at 100% and your power bills low.


Heat Pump Servicing

To keep a heat pump working at peak efficiency, it is important that your heat pump is serviced regularly.

If you use your system year-round to heat and cool, EES recommend that you have your heat pump serviced every year by a heat pump technician. If you only use it in winter to heat your home, or in summer to cool your home down, then a service every two years should be fine.

In between services, make sure your heat pump filters are cleaned to ensure they aren’t clogged. Vacuuming away the dust every 3 months is good practice, as is maintaining the area around your outdoor unit to ensure there are no leaves or weeds growing nearby.

If you haven’t had your unit cleaned in a while, then give us a call today. Our service technicians will ensure your heat pump is running at maximum efficiency.


What Is A Heat Pump?

A heat pump is similar to a refrigeration system and can be reversed to either heat or cool a space. Like a refrigerator, dust and dirt can build up on the working parts and affect the operation of the unit.

The heat pump systems consist of two parts: an indoor unit that distributes the air in the room in which it is fitted, and an outdoor unit, referred to as a heat pump. A compressor circulates refrigerant that absorbs and releases heat as it travels between the indoor and outdoor units.

It is therefore important to keep both the indoor and outdoor units free from dust, debris, and plants in order for air to flow freely through the system.


How Does A Heat Pump Work?

When it's cold outside, a heat pump extracts any heat energy that is present and transfers it inside. When it’s warm outside, the heat pump reverses direction, removing warm air from your home, thus cooling it down. 

This is what makes heat pumps are so efficient. Heat pumps move air instead of simply generating heat. A well-maintained heat pump will help ensure that the air moves freely and easily, meaning the unit won’t struggle to perform.


How To Maintain A Heat Pump

Here is a checklist and some handy hints if you want to maintain your heat pump yourself. Of course, if you need any help, then give our technicians a call on 0800 337 123.

  1. Inspect the filters for dust and clean if required every month.
  2. Consider changing out your filters once a year, or every two years for light use.
  3. Maintain the system according to your product manual - See the handy links at the bottom of the article for all the major brands. 
  4. Clean the outdoor unit whenever it appears dirty and ensure that any water is free to drain. 
  5. Remove clutter from around the outdoor unit to prevent things from being sucked in by the fan. 
  6. Gently clean the supply and return registers in your home and straighten their fins if bent. The register is the grille with moving parts that opens and closes with the airflow.


How To Clean Heat Pump Filters

If your heat pump is not performing as well as it used to, then the likely cause is blocked or clogged filters.

It’s not a difficult task to clean a filter but may require a ladder if the heat pump is installed high up on a wall. Check your manual and follow the instructions, and be sure to secure the ladder properly before use. Locate the filters, as shown in the manual, remove them, and then either vacuum them or give them a wipe with a damp cloth.

If you’re using the heat pump regularly then you should clean the filters every few weeks. If your filters are clean then the less work your heat pump will need to do to flow air around your home.


How To Clean the Outdoor Unit

Clean the outdoor unit with a hose to remove any dirt or salt spray build-up. Remove any cobwebs, dead leaves, plants, sticks or other debris that could obstruct airflow. Cleaning should be done on a regular basis if you live close to the sea.

Make sure there is always plenty of clear space for air to enter from the rear and exit the front of the outdoor unit.

Common Heat Pump Faults

If your heat pump won’t switch on, check the batteries in your remote control. Next, check the fuse box. Finally, check the isolating switch located near the outdoor unit is switched on. If these steps don’t solve the problem, then give us a call on 0800 337 123.

If the heat pump isn’t heating, check that the right mode is selected i.e. the heat or the sun symbol on the remote. Turn the temperature up and run for 30 minutes. Turn the fan speed up and run for 30 minutes. If the power light is flashing, this normally means the heat pump is in defrost mode. Wait for 30 minutes and then it should start to heat again. If these steps don’t work, give us a call on 0800 337 123.

 If the power light is flashing, it means that the heat pump is automatically defrosting. This will typically happen in the colder months. Wait for 30 minutes and then it should start to heat again.
