FAQ
How often should I get an AC tune-up?
The DOE recommends regular professional service. Many Sacramento homeowners schedule one each spring, and a heating check in fall.
How often should I change my filter?
DOE suggests cleaning or replacing filters every month or two during the cooling season, more often with pets or dust.
Can I clean the outdoor unit myself?
You can keep the area clear and gently rinse the outside of the coil with the power off at the disconnect. Leave the inside of the unit to a technician.
