Today was our six month servicing for the AC units. Jonathan was very friendly, professional and knowledgeable about the unit in both upstairs and downstairs. I would highly recommend REX AIR for the Keys. Jonathan was exceptional and a true service pro. Thank you REX AIR! Have had a service contract with them for years as well as installation of new A/C, of which the placement of took some creativity.

Alex called me and told me he would arrive at my place in 20 minutes. Alex arrived on time. I met Alex outside my house and asked what exactly do you do for maintenance on an ac. Alex gave me a thorough explanation what he’s going to do on the ac at my house. I must say he did exactly what he told me was going to. I was totally impressed with Alex. He did an outstanding job. He took his time and checked out the system thoroughly. I think Alex should be commended on his job performance and his attention to detail. Job well done Alex. Ty for your help.

Had our routine service today by Alex.
He called before arriving and was right on time. Answered all my questions and concerns and did a great job with our routine check up! Also made great suggestions for future product that would keep the AC running efficient. I would recommend Rex Air for all your AC needs.

Very dishonest company. Be carful if you need to check you A/C unit because they tend to brake/damage the unit instead to charge double the price. Not recommended at all.
The proof of this statement is that I called another company and they showed me the part that they damage on purpose that it was in perfect condition. But the issue for which I originally contacted them was an easy fix so they brake the part that was good to charge more. The owner of this company should be shameful of what his company is doing to Keys residents.

We had Rex Air replace our ductless split unit.
Their response with a call back and quote was the same day and they set up install within a few days.
The install took place when scheduled and was completed professionally and neatly.
I would definitely recommend Rex Air to other potential customers.

I highly recommend staying away from these people. They charged me $225 for a clogged AC drain that took 5 min to clean. You have to be kidding me. What a rip off. And I already knew what the problem was before they got there, I just didn't know how to open it. I have a small business and I would never screw a customer like that.
