“After a weekend away we arrived home Sunday night with no AC. I called Dunn first thing Monday morning and had a technician here within the hour! He explained that the unit could either be repaired or replaced and gave us a quote. We decided to replace the unit and that same morning they had a crew here installing it! The installers were friendly, neat, professional and skilled.
Very happy with Dunn and would recommend.“
