    Nick P. was very professional and knowledgeable. He took care of the issue right away and got our heater up and running again. I’d use him again

    I had Donnelly's install a new furnace 1-2 year’s ago and they did a quality job. They reached out recently and offered a service on my AC before the summer. So I had them come out and a very nice young man did the inspection. He said the refrigerant level was ok, but looked like the outside unit needed cleaning. I declined, as I am a retired HVAC professional, and took a look after he left. He was right, so I took it all apart (a dirty job) and not only was it real dirty, but the bottom 2 inches was covered in mulch. I need to thank them for pointing this out, as I am not as proactive as I used to be, getting up in age. Can't say enough about the quality of their employees, their professionalism and their work.
