My service was provided by Josh. He came out and got my heat running again. He was fantastic and answered my questions flawlessly. Someone I felt I could trust in my home without me monitoring them. Very happy with him and the companies product. Update: heat was running but my 20 year old unit decided to die again. Got a quick estimate and the price was comparable to other companies. Had my unit installed today. Financing was easy. Jake came out with another guy to do the install and it was a full day.

But credit to them for working through the downpour to get the install done. System is running smooth and my air is cold once again. Very satisfied with the business and the accommodations made by Donnelly's to not rip me off. As in since the previous work didn't hold up bring my old unit back to life, I was able to get the price of the new unit knocked down. Saved me a good chunk of money.

Brian Tapper, Service tech for Donnelly's plumbing and heating, did a complete yearly heat and A/C checkup today. He was Professional, courteous, informative and was very thorough. He answered every question clearly and without pause and to my satisfaction. He reminded me of an old school type repairman who still took pride in his work and instilled confidence regarding his work ethic. Hope to get him again next year.

Professional and smart technicians. They have conducted regular maintenance as well as installed replacements for outdated/non-working parts. I really appreciated the same day service as they had all the parts and pieces ready to solve any issue. Basically, they did not have to come back another day and my system was working the same day that they arrived. I also felt their recommendations and prices were fair, on target, and not excessive or unnecessary. Very happy with the work and I'm confident that the systems will work properly.

Had a plumbing emergency two days in a row and they responded immediately both times. When the first quick fix didn't hold, they came back to do a full drainage pipe replacement the next day. Response times were good and they had all the parts available immediately. Service guys were communicative and thorough, and even helped scrub up some mess from earlier leaks. Very happy with the replacement so far, though it felt slightly pricey. I don't have much to compare it to however. Worth it for the speed and peace of mind regardless.

Donnelly's did an excellent job from start to finish! We were in desperate need of replacing out heating/AC unit. Matt from Donnelly's came out not long after my initial call. He was informative and not pushy (as some of the other companies we called had been). Once we decided to go with Donnelly's (after a great recommendation from a friend that had just used them as well), Alicia was so gracious in helping us over a weekend to answer questions and then getting us on the schedule that Tuesday (Monday was a holiday).The day of install then brought Brandon, Jeff and David to our home.

They were on time and very efficient in getting the work completed. They helped ensure we understood the new system and thermostat and answered any questions we would have! We would highly recommend Donnelly's!
