Had problem with A/C emergency pan building up water level, had Oalmann (Brad) come out and clean outdrain on affected unit and also our other two units. He did a site assessment of our units and found that two ofthe units were sharing a drain line. He proposed a solution and came back a week later to implement it after we agreed. Brad has helped us out before and as usual gave us outstanding service and was very professional and knowledgeable. Thank you, Brad, and thank you Oalmann AC and Heating.
