“We've been doing business with Kelly and Dawson Service for a long time, and they’ve always been fantastic to work with. Most recently, our AC went out on a Sunday right when we needed it most. We called Kelly and Dawson, and within just 30 minutes, their technician Caleb showed up at our door. He was friendly, knowledgeable, and had the issue diagnosed and fixed within an hour.

We couldn’t have asked for better service, especially on a weekend. Highly recommend this company and their awesome technicians. Whether it's routine maintenance or an emergency repair, they’ve always come through for us.”

Our AC went out late on a Friday night. Kelly & Dawson were there first thing Saturday morning. The gentlemen was polite, very experienced, and had us back up and running in 30 minutes. The service fee was reasonable as well. I would recommend them in a heartbeat!

They checked my furnace and got it all ready for winter. Very courteous and professional. An excellent company with outstanding customer service. I highly recommend them for all your heating & air needs.

This company is so great. Bought a new central ac unit a year ago. Today was the first maintenance/check up day and Daniel came out. From the beginning of buy the unit, the communication with everyone at Kelley and Dawson has been great right up to this morning when Daniel checked and cleaned the ac. Efficient, friendly....this company reminds me of living in small town with wonderful people when you need service.

We've been using Kelley & Dawson Service for 5 years now and they've been wonderful every single time. Caleb is super kind, polite, and really professional. They always take great care of us – highly recommend!
Christina L
We’ve used them in the past for a new furnace and have not had any issues to date We called them out this past Saturday when our AC went out. The initial caller let me know a technician would be calling me. When Daniel called he let me know he had a couple clients before me and then would be out. He called again to let me know he was on his way. Daniel was respectful and found the problem quickly. Very affordable for an emergency call, part and labor. Thank you for the great communication and prompt service!
