The cost of heat pump repair in Bend, Oregon, depends on what’s wrong with the system, so it’s difficult to give an estimate without an inspection. Clogged air filters are common reasons behind heat pump problems. If you change the air filter quickly enough, you might be able to prevent additional damage. Dirty air filters are a serious problem because they restrict airflow and overheat your heat pump. You should change them on time rather than wait for your heat pump to stop working correctly.
