  • Check the Thermostat

The thermostat is the control centre of your heat pump system, so it’s important to make sure it’s set correctly. Start by checking the temperature setting to ensure it matches your desired comfort level. If the heat pump is not turning on or off as expected, try adjusting the temperature a few degrees higher or lower to see if it responds. If that doesn’t work, check for any loose or faulty wiring connections. Ensure that the thermostat is properly calibrated and, if necessary, replace it with a new one.

  • Inspect Air Filters

Clean air filters are essential for efficient heat pump operation. Start by locating the air filters, which are usually found in the return air duct or inside the air handler unit. Inspect the filters for any signs of dirt, dust, or clogs. If the filters are dirty, clean them according to the manufacturer’s instructions or replace them if they are beyond cleaning. Regularly cleaning or replacing air filters will not only improve the performance of your ducted heat pumps Christchurch but also ensure better indoor air quality.

  • Examine Outdoor Unit

The outdoor unit of your ducted heat pump is exposed to the elements and can accumulate debris, obstructing airflow and reducing efficiency. Start by checking for any leaves, branches, or other debris around the unit. Clear away any obstructions and ensure that there is at least two feet of clearance around the unit for proper airflow. Inspect the fins on the outdoor unit and straighten any bent fins using a fin comb. If you notice any damage or suspect a refrigerant leak, it’s best to contact a professional HVAC technician for assistance.

  • Evaluate Ductwork and Vents

The ductwork and vents play a crucial role in distributing heated or cooled air throughout your home. Inspect the ducts for any visible leaks, loose connections, or signs of wear and tear. Seal any leaks with duct tape or mastic sealant to improve efficiency. Ensure that all vents are open and unobstructed to allow proper airflow. If you notice any significant issues with your ductwork, such as extensive leaks or blockages, it’s advisable to seek professional assistance. However, you can also check for and remove any dust or debris that might be blocking the vents yourself.

  • Consider Power Supply and Electrical Connections

A reliable power supply is essential for the optimal performance of your heat pump. Start by checking the circuit breaker or fuse box to ensure that the heat pump’s circuit breaker has not tripped or blown a fuse. If it has, reset the breaker or replace the fuse and monitor the system to see if it resolves the issue. Inspect the electrical connections, looking for any loose or disconnected wires. If you are uncomfortable dealing with electrical components, it’s best to seek professional help for ducted heat pumps Christchurch locals rely on.
