Joe was quite good and thorough. He was able to shut off the water and install the new pressure release valve so we didn't have to rely on the unreliable water company tech who didn't show a couple of days ago. Joe also trouble shot a persistent pressure problem with my kitchen faucet. Checked a couple of potential sources in the faucet with no answer yet. Will return to check a valve source. Have confidence in Joe and look forward to his return, answer, and fix. .

I wanted to edit and update my review for Donnelly's. I have been using them approaching 5 years now and I am extremely happy and satisfied with their service to my homes HVAC and plumbing needs. All the HVAC Technicians and Plumbers have been very nice and professional in their visits and service to my home. They always explain clearly what they are doing and what services are recommended when doing their inspections or repairs. They are always respectful and neat when working in or outside my home. I am also excited about their new Electrical Division and will certainly use them for this service as well for my home. I also want to give recognition to all the support staff (Representatives who answer the calls and the dispatchers) I am very appreciative of your work and professionalism. Thank you Donnelly's for helping in keeping my homes HVAC, Plumbing and Electrical systems working and running great!!!
