Heat pump diagnosis and repair for Marin and Sonoma County homes with weak heating, poor cooling, short cycling, noise, or comfort problems.
A heat pump should heat, cool, and dehumidify reliably without constant resets or surprise spikes in energy use. If the system is short cycling, blowing lukewarm air, icing up, or struggling to keep up, the right repair starts with careful diagnosis.
John Owens Services repairs and services heat pumps across Marin and Sonoma County. We look at airflow, controls, refrigerant-side symptoms, electrical issues, and equipment condition before recommending repair or replacement.
Our team works on the full comfort system, so repair recommendations consider the heat pump, ductwork, controls, airflow, and the way the home actually performs.
Yes. We service heat pump systems, ductless mini-splits, and related airflow or control issues for Marin and Sonoma County homes.

Yes. Duct restrictions, dirty filters, blocked returns, or airflow imbalance can reduce performance, so diagnosis should include the whole system.
