We needed our a/c checkup before summer and called Desert Wolf Air Conditioning. Aaron arrived at the time he said he would. He spent hours thoroughly checking and cleaning our units. He was most helpful in recommending ways that we could perform our own maintenance on the units to prolong their life and improve efficiency (and save money). Our units work great and we are much cooler this year. By the way, Aaron isn't just a tech, he is the owner and takes GREAT pride in the work he does. We are customers for life!
