I’ve been using Great White Mechanical for over 12 years now for my Air Conditioning systems. My boiler just blew and flooded half of my basement. I got 3 quotes from reputable companies, the third being Great White Mechanical. They were the only company not trying to oversell me on things I didn’t need. They gave me 3-different efficiency options with no pressure, only advising me on what they would do if it were their home. They showed up on time, were very neat, and did a great job. The neatness of the piping and overall job is top-notch. Very happy with their service and will continue to use them in the future!
