"Arrived quickly and diagnosed the problem in no time. Polite and respectful."
Anthony, Camp Hill
"DNR was great! Came in, on time, under estimate and replaced a compressor that the part was covered under warranty but not the labor and refrigerant. Clean, and very professional and the cost was much less than our previous service person wanted to charge. Our unit runs better than it ever did. I would highly recommend!!
Thomas, New Cumberland
"Our outside central AC unit died. Our home warranty company was dragging their feet on finding a contractor to come out, so I looked on Home Advisor. I came across DNR Services and read the great reviews yesterday. I decided to make an appointment to have them come out this morning. Arrived on time and had diagnosed AND replaced the bad part within 10 minutes. Even better, he was very reasonable and affordable. I'm glad I didn't wait on my home warranty company. I don't even need to be reimbursed by them because of how affordable the services from DNR were. As a hard working family that lives paycheck to paycheck, it can be very stressful when unexpected circumstances come up, because you worry how you'll pay for them. That wasn't the case here and I'm forever grateful for that. Thanks for the excellent service. We will definitely use you for future needs!"
