Have been using this business for slightly over a year and happy with. Have also had the same technician who I specifically requested as feel that’s best for an optimal experience since they get to know your home and needs. Would definitely recommend based on my experience thus far..

Couldn’t be more happy with the response time in a time of need. Larger more commercialized company had a 6 day wait. Thank you for living up to your name during a very hot and busy time here.

Everything about Dunn is great from beginning to end! I work in a similar field and was super impressed with Erik. He was able to diagnose the issue and once parts were available, fixed my ac quickly. Erik is very knowledgeable and made sure to explain everything. He was very polite and is just a nice guy. Thank you Dunn and Erik for helping my family stay cool.

OMG! Eric was so helpful, kind, and knowledgeable. I will most definitely be asking if he available if I need anything else regarding my air unit. Very professional business they didn't waste my time like the others that never called back and prices were not bad either.

Got a targeted ad. Was skeptical. Checked Google reviews. Nearly 100% 5 stars. Still skeptical. Called them. Two hours later was face to face with Erik. Had a nice chat with the owner. Signed the deal. Two days later the AC is in and working well. The whole process was seamless. Nothing but good the whole way. So now I believe the stellar ratings.

I had them out for a bid on an hvac unit and they were upfront about the work that would need to be done and in the end i did not end up selecting them but I appreciated the honesty.

Came out same day and sent an actual technician that can do work, not someone to do diagnostic then schedule another apt to get service. Will definitely use going forward. Tho hopefully I don't need to. Diagnosed and fixed in a couple hours! Farrell was very nice and professional.

Dunn Heating & Cooling bought our prior HVAC company, so this was our first experience with their service. I was very happy with the service provided by the HVAC repair tech, Robert. He was friendly and worked efficiently and solved our issue quickly. Very happy with the quick turnaround time of the service call and the repair!

Spring maintenence service. Erik was the technician, and he was on time, neatly dressed, professional and friendly. He didnt mind answering questions and he explained what he was doing and why. Gave good recommendations on how to maintain system. Would definitely use this company again and recommend to others.
