Fast reliable service. I made a call to Clawson Mechanical early Friday morning, and they were out here the same day ready to repair my a/c unit. The technician found the problem quickly and had my unit up and running in minutes. After the repairs were complete, he inspected the unit to make sure everything was running well, and replaced a problematic thermostat at my wife's request. I highly recommend CLAWSON MECHANICAL SERVICES INC.
