I recently switched from my 15 years plus HVAC guy to Kellam Mechanical. Totally nervous woman of a certain age who has 2 very special, extremely high maintenance rabbits. Scheduled an AC maintenance appointment and truly have never had such fabulous service! LT was patient, kind, and explained everything using terms I could understand. Have a 14 year old system that he is helping me nurse along until I can afford a new unit. The second young man, who came out after I thought the fan was in death mode, was equally wonderful. Hopefully my unit will last through this heat wave; however, I am not as nervous due to knowing they will lend me a portable unit to keep the buns cool. Thank heavens for Kellam! They definitely go above and beyond in both maintenance and customer service!
