“Matt with McCarthy's did a fantastic job.I normally do not leave reviews but Matt was wonderful to work with. He was on time, professional, and friendly. He let me know what was wrong and was able to do the repair around our busy schedilule. He made some recommendations but didn't try to pressure me into anything extra. I really appreciate the level of service we receive everytime McCarthy's comes to do yearly maintenance too. I highly recommend their services.”

“Lwu did a very good job & very detailed. Only complaint is when I spoke to Mckenzie to schedule appt. She said there are possibly some coupons on their website for my service & I did find one. When I presented this to Lwu he said they do not honor those anymore only a gift card. You might want everyone on the same page when it comes to this issue. Thank you Lwu for your great service!!”
