Eric Merson is an excellent technician. He and his partner came to get the house ready for A/C check and set the thermostat at the temp I wanted for summer time. Changed the air filter. I told him I wish there were other longer lasting filter because every 3 mos. I had to pay #69 for changing the tilter, wasn't happy about it! He showed what can be done but it is something I can't afford. He understood, didn't pressure me to get this done. He is the kindest, caring, tech I've ever had the pleasure to meet. I mentioned I should have the air ducts cleaned again, he said we do that too! I checked the invoices the last time that was done was in summer of 2017. by Sierra Air. I joined the home care club in mid 2017 with very small monthly dues. I am happy I did but at time very few techs i met wasn't very impressive, almost thought of cancelling the contract. The way Eric took care of A/C set up and very dependable, caring and kind service changed my mind. I will stay as a member. Sierra Air should be proud to have him represent their company. That's why the 5 star.
