A heat pump requires regular inspection to maintain its function to work correctly. You should not hesitate before calling a certified professional if you noticed any of these:
Leakage: If your heat pump is broken, there might be some issue with the ducts in the system, causing water to leak.
Burning smell: An overpowering odor caused by internal wire friction, or some other severe issue that has yet to surface, needs a visit from a technician.
Not working correctly: It stops cooling or heating itself, showcasing the underlying threat that needs to be resolved immediately.
