It captures or rejects heat outside. It sits on a level base, above the snow, with free space all around.
The insulated refrigerant lines enter the house through a sealed opening and run to the indoor coil.
A shut-off switch near the outdoor unit isolates it safely for service.
Sitting on the indoor module, it moves heat between the house air and the refrigerant.
Electric furnace or air handler: its fan pushes air through the ducts. The electric backup takes over in extreme cold.
Supply ducts bring air to the rooms; returns bring it back to the unit. Their condition matters as much as the unit's.
It protects the coil and the fan. A dirty filter cuts airflow, so it gets checked regularly.
It runs the heat pump and the backup heat. It must be compatible with the installed system.
At AirGreen, we understand the importance of having a heating and cooling system in perfect working condition, especially during extreme seasons. This month, we had the opportunity to assist a customer in Kirkland, where a heat pump was experiencing performance issues. Find out how our team quickly identified the underlying causes and performed a quality repair to restore comfort to the home.
Troubleshooting and Diagnosis: A Heat Pump Facing Difficulties
When we received the service call in Kirkland, our client informed us that their heat pump seemed to no longer provide sufficiently warm air during the cold winter days. While the unit appeared to be functioning intermittently, the heating was far below normal standards, causing discomfort throughout the house.
After a thorough analysis of the system, our team of AirGreen experts quickly pinpointed the likely cause of the problem. It became clear that the electric furnace and air handler of the heat pump had developed a failure in the ventilation system, hindering the circulation of warm air. An obstruction in the ventilation duct, likely caused by accumulated debris over time, was identified.
Precise Diagnosis: Why Your System Needs Regular Maintenance
One of the most important aspects of this intervention was highlighting a commonly overlooked factor: regular heat pump maintenance. When a heating and cooling system is poorly maintained, small issues, such as clogged filters or obstructed ducts, can quickly turn into major failures.
In this case, our inspection revealed the accumulation of dust and dirt in the filters, as well as a blockage in the ventilation system. These issues had not only reduced the system’s efficiency but were also at risk of causing larger-scale failures if left unresolved.
AirGreen's Intervention: Repair and Restart of the Heat Pump
Once the issues were identified, we proceeded with the heat pump repair in several steps:
-
Thorough Duct Cleaning: The first part of the intervention was to conduct a detailed cleaning of the ventilation ducts. Using specialized equipment, we removed accumulated dust and debris, which restored normal airflow.
-
Inspection and Replacement of Filters: Another key part of the maintenance was replacing the clogged filters. Clean filters allow air to flow more freely, improving system efficiency and air quality in the home.
-
Air Handler Inspection: We also carried out a full inspection of the air handler, one of the essential components of the heating system. By checking the electrical connections and overall setup, we ensured that the unit was functioning under optimal conditions.
-
Performance Testing: After the repair was completed, we conducted several tests to ensure the heat pump was operating at full capacity, ensuring that warm air would be properly distributed throughout the house.
Repair Results: Comfort Restored Quickly
After our intervention, our client in Kirkland immediately noticed a significant difference in the performance of their system. The warm air was circulating evenly throughout the home, and thermal comfort was quickly restored, even during the coldest winter days.
Not only is the system now more efficient, but the risk of future breakdowns has been reduced thanks to the preventive maintenance we carried out. Our clients expressed their satisfaction with the speed and quality of the service, which is always a top priority for AirGreen.

2. In extreme cold, electric backup heat can take over.
The indoor module (furnace or air handler) works with the heat pump and takes over in extreme cold.
3. The filter only gets changed when the unit breaks down.
A dirty filter cuts airflow. It gets checked regularly.
4. You can reuse the old unit's size without checking.
