Featured Castle Rock AC repair story


Replacing an AC dual capacitor


Jean, a Castle Rock homeowner contacted us for an AC tune-up. However, Billy, our technician discovered that her AC's "dual capacitor" wasn't working properly. The dual capacitor is essentially a battery that jolts the AC's motors on and then keeps them running.


Billy replaced the dual capacitor that same day.
