I called Rex Air to check my AC as we recently had Roof work in our Condo Building in Key Largo and the AC units had to be lifted and placed in top of a metal frame, I had noticed water penetration on the filter and dropping in the floor, especially after rainy days, so I thought there must be a problem with the AC or the way it was re-installed in top of the frame. Joe Smith was the Technitian that was assigned to my request of service, from the moment he arrived to my Unit he was very respectful and attentive to my concerns, he was quick to go up to the roof, and as he was there he took several pictures and texted them to me, he found nothing wrong with the AC, it was actually the material used in the floor of the roof was not sealed correctly, he also confirmed that the water coming thru the filter was not coming from the AC, but from a roof leak. Joe Smith is an excellent employee for Rex Air, I highly recommend him if you want responsible service from a friendly person that takes his time to explain what he has diagnosed and what needs to be done.

As an old, somewhat jaded, long-time resident of the Keys, I have come to expect good service from just a handful of businesses: FKEC, Keys Sanitary, FKAA. (Okay, there are a few more.) I was skeptical I would add REX Air to that short list. But, a gaggle of young men showed up yesterday at 8:15, as promised. They were polite, respectful of my home, and in spite of a difficult install, exchanged happy banter while they worked. The best news is, my new A/C is a surprising improvement from my old A/C. I had grown to accept waking throughout the night to throw-off the covers until my A/C kicked-on and my bedroom cooled down again. My A/C never kept my house at a constant temperature. I awoke multiple times last night, from habit I guess, and although the temperature was perfect, I listened for the noise from the new A/C. I drifted back to sleep while trying to decide if it was running or not. I am going to enjoy making a new habit of sleeping through the night. Thank you Roman, Levi, Alex, Tommy, and some who's names I'll never know. I highly recommend REX Air. read more

After Hurricane Erma one of my AC units quit. Rex Air sent out a great Service Technician to add some Freon and schedule a leak check. Kenny then came out to do a leak check and found the problem. We then discussed installing a new system. He was also great. I decided to get a quote from Rex. The quote came quick and I had a choice of three systems to choose from. Good, better and best. Rex Air was very busy after Erma but was able to install the system quickly. My professional Service Technicians were Johnathon and Alvin. They were a great team and new exactly what to do. They were very friendly and made sure to clean up. My dog Sugar hung out with them and kept asking for belly rubs. The installation was fast and I am very pleased with every aspect of dealing with Rex Air. Andy M. read more

Our 9 year old 5-Ton Carrier failed twice in the past 15 months, after years of flawless operation . On both service calls Rex Air was very quick to respond (same day) even though Rex Air did not install the unit. Nick, came out on both service call. Both failures were promptly diagnosed and taken care of effectively and professionally with help from Office Staff (Administrative-Ronda and Melody & Technical- Kenny). Great communication and excellent teamwork. Each individual went the extra mile to offer the best service possible. First failure was a leak in the condensing coil outside and the second failure with a blown variable speed blower motor, both under Carrier warranty. Thank you and keep up the excellent local service, Rex Air. John K read more

The entire Rexair team - Mary in the office, Jonathon and Alvin in the field - were our saviours. Our winter mobile home in the Keys was flooded in Hurricane Irma. After our contractor angels ripped out the old HVAC system and put in new floors Rexair got right on it. They installed dual mini-splits and the place was cool in hours! Our original schedule date got pushed back (so we had one night in the heat, but they were able to squeeze us into a cancelled slot so we were only a couple days late. The install was professionally done. Special credit to Mary who was contacting us regularly right after the storm and stayed on top of our order all the way in spite of what must have been an incredibly busy time post hurricane. read more

Michael and Dave were very knowledgeable, professional, courteous and quick! They answered all of my questions and cleaned up after themselves. I highly recommend this team of Michael and Dave. I had not had a good experience the last time with another team and was going to cancel my maintenance agreement but this visit today made it so much better!!! Gave me a time and actually was able to come earlier in the day. Great job all around and like the calls and emails beforehand. Kudos to the receptionist, Whitney also! She was great at setting up the time and appointment! Will continue to use them! Thank you Michael & Dave! read more

I called Rex Air for service on our A/C which had been crapping out on us. When I made the appt they told me that for $20 more I could get free filters for a year and 2 check ups to keep things running smooth. On top of that I would get a discount on services. It seemed like a no-brainer so I decided to go for it. They showed up on time did a complete check up on my system and found a bad capacitor on my unit. The savings I got for the replacement already paid for the cost of the maintenance agreement. So far very pleased with the service. read more

Mike at Rex Air has been my "go to" guy for any of my air conditioning issues. Having 4 air conditioners for my home there are plenty of problems and Mike is always there with a positive attitude and ready to get to work. He shows up on time or even earlier than expected. Its nice to have someone in the industry that you can trust. Being in the Florida Keys you never know if anyone is actually going to show up or go fishing. I have not had that issue with Rex Air. Excellent service. read more

Rex Air service is prompt, fair and efficient. Recently, technician Michael M. came out twice and did a great job. First, our condenser died on a weekend. Michael the go to emergency tech gave me phone advice that saved a useless weekend visit and expense. Eventually he, and Rex got the problem resolved in record time. No fuss no muss. He also did efficient maintainance. I've purchased a central system and a mini split system from Rex. Installation was quick, clean and proficient. read more

I have an inexpensive mini-split that stopped cooling yesterday. I called this morning, and within 15 minutes had a technician (Mike) checking it out. He serviced the unit, made some recommendations, and scheduled a return for next week. Very polite and knowledgeable, and not afraid to explain what he was doing. I would recommend him to anyone. Rex may be a little pricier, but here in the keys AC is a necessity, not a luxury. Quick response and skilled techs are worth the price. read more

A/c went out on the hottest day of the year. The lady on the phone at Rex Air was polite and professional and emailed me the name and photo of the technician who arrived promptly. Shane knew immediately what the problem was and took care of it... Quickly He also checked on the warranty to help us replace the defective part. He prepared my bill and explained it to me and it was perfectly reasonable. I will absolutely call Rex Air for any a/c needs in the future. read more

Ac went out the Wednesday before Christmas and was unable to get another unit here until the following Tuesday due to holiday. Rex Air called Tuesday said the installers would be here at 8:00AM Wednesday morning Jonathan and Vince arrived right at 8:00 and got right at it. They were super nice and informative young men. Installation done they clean up any debris and were on there way and my house was nice and cool. I would recommend Rex Air to anyone read more

Jonathan and Alvin were great. They worked as a team, were very coordinated and prepared. They encountered a couple of roadblocks during the replacement of the HVAC system and quickly developed solutions and got back on schedule. They also were very accommodating when I requested some additional sealing of duct work not in the scope bid and quickly took care of the issue. Highly recommend them and RexAir to everyone. read more

Our central a/c unit began to leak and had diminished cooling: It was just not getting cool enough. RexAir answered our call right away and scheduled service quickly from its office. Michael M. came exactly when projected and not only repaired our unit but explained what he did. On top of that, he was personable and professional. I haven't been this impressed with a service call of any type in a long time. read more

I had a complete install done and I couldn't have been happier with the professionalism of the staff. The staff was extremely respectful of my house and left everything clean and worked very efficiently to ensure that any debris from a total install would be next to nothing. I have two boys with severe asthma so this was extremely important to me. I would not hesitate to recommend this company. Thank you read more

Very professional with fair and honest pricing. They communicate the issues clearly and provide options as to how to fix the problem. I have been a customer for several years. They were referred to me by another happy customer who owns multiple rental units and needs to keep the AC in top working order. I have worked with other AC Companies in the Keys, but so far Rex Air is far superior. read more

Rex Air installed a new Lennox system for me on March 1. I was impressed with Rex from the start! Quick response to my initial email and all questions promptly answered thereafter. Super fair price AND advise on how to get a $500 rebate! Professional, prompt, and I didn't have to clean up a thing after they finished. A pleasure to deal with Rex Air, I highly recommend them! read more

My HVAC Systems at my home in Key Largo needed to be Replaced so I called Rex Air. They quoted the job, scheduled it, showed up as promised and I paid them exactly what they quoted. It's been 4 days since they installed the New HVAC Systems and so far all's good. Jonathan and Vincent did the installs, they were Courteous and Professional. I would recommend Rex Air for sure. read more

Jonathan and Alvin are a great team! Courteous, cautious, and well prepared. I do not own the home I was renting it on my vacation. I was able to work all day comfortably while they replace both A/C SYSTEMS in the house. I am a general contractor in Miami and rarely see this professionalism. Can't comment on price but I am sure it i worth every penny! read more
