Purchased new AC at a fair price and couldn’t be more pleased with the results. 2 techs, Anthony and Jesus, came out to install and did it in less than a day. They were friendly, polite and professional. Before starting they explained everything they were going to do and answered my questions and concerns. When they were done they cleaned up after themselves and hauled away my old unit. As I said, I couldn’t be more pleased and I highly recommend Service Now.

Andy was our service guy, he was exceptional, very experienced. Very easy going and explained everything in detail. I loved the experience as he took our stress away. He is a valued employee and you have a customer for life. Thank you so much Andy

EXCELLENT SERVICE! 😄 If you get Stella R. to come to your home and help you out then you are in good hands. Seriously!! She did an amazing job! She was super communicative with explaining what was happening and finding a solution for our problem. We are very pleased with the service.

I had a persistent basement drain backup that I couldn’t resolve on my own. Nate from Services Now Home Services came out while I was at work and took care of everything. He was professional and friendly with my family, explaining his process clearly and sharing what he found. He also taught me about common plumbing issues in older homes like mine and gave me great tips for preventative maintenance to help avoid future problems or at least delay them as long as possible. After talking to Nate after he fixed the problem, it was obvious that he stands by his work. I really appreciate that kind of confidence and pride in craftsmanship. This is exactly the experience I hoped for when hiring a professional to fix an issue in my home. If I ever have any plumbing needs at my house again, I’ll absolutely call Services Now Home Services. Thanks again, Nate!

I’ve been trying to get help with a billing issue since September 2025 and their team hasn’t gotten back to me despite multiple attempts. I keep getting put on hold with an AI chatbot. Can someone please follow-up?
