      John and Ian in the servicing team were great. Our AC died during a heat wave and they were prompt and easy to work with, even when giving us the news we hoped to avoid, that the full system needed replacing. Very happy with our choice to use Donnelly

      Derrick was great! He explained Everton us. It wasn't as serious as we thought. Will definitely go with Donnelly' s again for any plumbing issues.

      Jeremy really knew what he was doing. He ran into some unexpected problems and quickly and expertly addressed them. Kept me in the loop every step of the way and explained everything. I really appreciated his professionalism and he’s a really nice guy as well.
