They provided the most detailed quote at the best price and did an outstanding job installing our new system quickly for us! Highly, highly recommend! Thank you Dunn Heating and Cooling!

I had them come out for sewer issues. They said I would have a bid the next day. A week and a half later I had to find another company. They were to busy to even bid the job. Would definitely not recommend them

Reggie was amazing!!! Arrived within 45 minutes of my call. He assessed the situation & Repair was done within 30 minutes!!!
Wish I would have called Rooter Man sooner. Tried to repair myself( huge mistake on my part)...do yourselves a favor....call Rooter Man first!! Excellent service, VERY fair price....Rooter Man saved my day!

Called in the morning, got service after lunch.

Collin was my technician. He is a very nice and capable young man. Collin was personable, and I see a good future for him in this business.
