When it came to replacing my Trane A/C unit of 25 years, it felt like dealing with car salesmen until I contacted Durham & Sons, Inc. I had read the reviews, but no company can be that good I thought... My first impression of the Durham and Sons, was with RJ, he didn't just walk around and take notes, he measured, checked piping, etc., very thorough. Even though it was a difficult install of unit on second floor in a closet, they didn't charge extra. Replaced the existing refrigerant A/C lines running them inside same as old lines, other companies refused or wanted to run them on the outside, how tacky. Every step of the install process was done professionally and done right. They are a one of kind A/C company, I had just returned from surgery with out A/C, once I made the decision to use them, they showed up with two portable window units, at no extra cost until the new A/C install was complete. All the installers were professional and courteous, will use them for all future A/C service/repairs.
