Bashman N.
My AC went out on the hottest day of the summer and as we all know that is the busiest day for AC repair. I was worried me and my family would be stuck sweating for at least a week but dragonfly heating and cooling saved me! After calling several companies and being told they didn’t have any open availability Dragonfly was able to send someone out same day and get it fixed and up and running before the end of the day! Reasonable price great customer service. I will never call anyone else again!
Response from the owner:Thank you so much for the 5-star review! We're thrilled to know you had a fantastic experience with us.

Words can not explain how happy I am with Dragonfly, what they did for me and my business was exceptional. I had a new system installed about 2 years ago and it was not performing correctly. The system was not reaching setpoint, Dustin Ramker work is exceptional. He tuned and cleaned my current system perfectly, it is performing better than when it was brand new! Thank you Dragonly, I am so greatful for your Honest & excellent work.
Response from the owner:Thank you so much for taking the time to leave us a 5 star review!
