Report
DuAll was great. They came out to my house to see what wrong with my unit as it wasn't turning on. They had to access my very hot attic to see what was wrong and identified the problem (was electric in nature). They then were able to fix my outside unit and the AC works great now. The cost was very affordable and the honesty by the technician, Larry Jr., was so nice. No sales tactics were used and only paid for what was needed. Very refreshing! Recommend them if AC is not running correctly or at all.

This was our 4th time using DuAll Heating & Cooling. This time it was for AC Inspection before Summer begins. It was also the second time Kat has been out technician. Very professional, actually a couple of minutes early. Very friendly and prompt service. I am so glad I started using DuAll. Service: A/C system maintenance

Kat was awesome. She explained what was going on and was very polite and engaging. She was also made a new friend with Sir, our Siamese Cat! Will always use DuAll for all our HVAC needs.

Called DuAll for a second opinion after being told by another HVAC company that our only 12 year old furnace was about to die and needed $4000 of repair work. Larry Sr came out for a thorough inspection (and actually showed me everything he did, unlike the other company) and found no such indication of any work being needed. I appreciate his honesty and will only be using DuAll from now on!
