If you notice unusual noises (grinding or squealing), weak airflow, or a sudden spike in your energy bills, it’s time to call a professional. At Double JJ Heating and Air Conditioning, our 10-person crew can quickly diagnose whether you need a simple part replacement or a more significant repair to get your system running efficiently again.

We recommend a professional tune-up twice a year—once in the spring for your AC and once in the fall for your heating system. Regular maintenance by an experienced HVAC contractor in Fairview, Oregon helps prevent unexpected breakdowns and extends the life of your equipment.

Yes! While we are a favorite for Fairview homeowners, we also specialize in light commercial properties. With over 20 years of experience, Darren and the team have the expertise to manage the heating and cooling needs of small offices, retail spaces, and other commercial buildings throughout the Portland metro area.
