Day 1 installing a new high efficiency Daikin Heat Pump and Air Handler in Brentwood, Ca. Can’t wait for our clients to experience energy efficient air conditioning in their home!

In the Brentwood area performing an AC maintenance! This 7 year old train condenser is in great condition! During the maintenance, I noticed the dual capacitor was very low, which puts our customer at risk of having NO AC during the hot summer! Notified our customer, and he agreed it would be a great idea if we not only switched out the dual capacitor, but add a component that will preserve the life of the unit. After I installed these components, the AC unit ran perfect!
