“Living in Florida our A/C is a necessity, When we have an issue we like promptness, told and guided correctly to what needs done or placed with HONESTY & KNOWLEDGE, without looking at how he the technician is going to make out on the deal. When he was asked a question he wasn’t hesitant on the answer. He Explains well on what he’s doing/done with the possibilities. Daniel Snell is top quality at customer service and their needs by being Honest & having the knowledge to do his job professionally. I would highly recommend him!”

“AC during the Florida summer is vital. So we were more than willing to pay the minor up-charge for the expedited visit. Daniel got here early during the time window and was a true professional. With rain starting to fall from an impending lightning storm bearing down on us, Daniel persisted with the repair on the compressor and quickly had our AC running again. Fair pricing and really quick service! I think we found our permanent AC company. Thanks Daniel, and I hope they're paying you well!”

“Called One Hour Air and they were able to be at my home same day. Nick E. was our technician. He was very polite, professional, and walked me through every step of his inspection and repair. He finished repairs same day and the quality of the work was outstanding. Nick was very knowledgeable and gave great recommendations on how to keep our AC running smooth and efficiently all year. All around it was a great experience and I would highly recommend. Thank you, Nick and One Hour Air!”
