Sergio and team came out the same day for what i thought was an issue with my outside unit (nasty buzzing sound.). They tested the compressor and capacitor- no issue. Sergio then asked if he could listen to the noise inside and tracked down a vibration issue with my inside duct work. Problem solved! Great and reasonable service! Much appreciated and will use again.

Amazing service. Expert troubleshooting skills. He diagnosed an issue that others had been unable to. Methodically troubleshooted our issue with our mini split which had a refrigerant leak and traced it back to the condenser unit on the roof. Had it repaired in the same trip. So happy I hired him!
