★★★★★

Called at 10 pm on a Saturday with no heat and someone actually answered. The furnace was running again before midnight. Cannot recommend them enough for anyone in San Mateo.

Installed a ductless mini split in our garage conversion. Neat work, quiet unit, and they walked us through the remote and app. Very happy.

Patricia H., San Mateo
★★★★★

Two other companies told me I needed a whole new system. These guys found a refrigerant leak, repaired it and my 8-year-old unit is cooling like new. Honest people.

Air Conditioning Service in San Mateo: frequently asked questions

How often should my air conditioner be serviced?

Once a year, ideally in spring before the first heat wave hits San Mateo. Systems that run most of the year benefit from a second visit in late summer.

Is AC service the same as AC repair?

Service is the preventive tune-up and cleaning; repair fixes a specific failure. Our service visit includes a full inspection, so if a part is failing we can repair it on the same trip.

Will service lower my cooling bill?

Usually yes. Dirty coils and low refrigerant can raise energy use by 20 to 30 percent. Cleaning and correcting the charge restores the efficiency your system had when new.
