The outdoor unit was frozen, and the house wasn’t getting warm. That was the reason a Newcastle homeowner called Fusion Heating & Cooling to look at their Bosch inverter heat pump. We found the system low on refrigerant, located a leak near the outdoor unit, and repaired it. After adding refrigerant, we had the heat back on during the same visit.
A Frozen Bosch Heat Pump That Wouldn’t Heat the House
The customer described the equipment as their AC, but it was a Bosch inverter heat pump that also heated the home. When it stopped delivering heat, the problem affected more than summer cooling. The homeowner needed the heating system working again.
Our diagnosis found low refrigerant. We then located the leak near the outdoor condenser. Finding where the refrigerant was escaping gave us a specific problem to repair.
Refrigerant Leak Repaired and Heat Restored in One Visit
We repaired the leak and added refrigerant to the system. The Bosch heat pump resumed heating the house, and the customer was happy to have the problem resolved without waiting for another repair visit.
For this job, we were able to keep the existing heat pump and get the heat back online. The work addressed the leak as well as the low refrigerant level.
Questions About a Heat Pump That Is Frozen or Not Heating
Does a frozen heat pump always mean it has a refrigerant leak?
No. A heat pump can develop light frost during heating and clear it through its defrost cycle. Persistent ice and a home that isn’t warming up need further diagnosis. Airflow, defrost operation and refrigerant problems can all be involved. In this Newcastle job, we found low refrigerant and a leak near the outdoor unit. Carrier’s heat pump troubleshooting guide explains the distinction between normal frost and heavier icing.
Can low refrigerant keep a heat pump from heating?
Yes. Refrigerant carries heat through the system, so an insufficient charge can affect heating performance. Here, repairing the leak and adding refrigerant restored heat. The symptoms alone don’t establish the cause; the equipment needs to be checked.
Why repair the leak instead of just adding refrigerant?
Adding refrigerant does not close the place where it is escaping. On this system, we located and repaired the leak before adding refrigerant. That addressed the problem behind the low charge.
Can a Bosch heat pump be repaired on the same visit?
It was on this job. We diagnosed the problem, repaired the leak and restored heating in one visit. Other repairs may need parts or additional work, so the timing depends on what the inspection finds.
