"Beware of shipping issues with this company. Ordered an ice maker installation kit on 10/10/25. Shipping was due no later than 10/20 according to company and FedEx tracking. FedEx tracking showed the package at their facility for 8 days without moving beginning on 10/15. Called FedEx 3 times. Each time they said they cannot find package and I have to contact shipper. Shipper has to make a claim, they will not mark it as lost. Called Appliance Parts Pros twice. Each time they say FedEx has to mark package lost before they will do anything. They also state they have to wait 14 days from them before doing anything because of their contract with FedEx. I don't care about their contract, I want what was ordered and paid for. Just going in circles with them and FedEX. If they shipped after 14 days it would be 22 days from that point, 32 days from the date of order if they shipped it that day.

REX AIR provides air conditioning services and refrigeration services to the Upper Keys. We specialize in install and repair of A/C, Commercial Grade Refrigeration, Pool Heaters and much more. We service all makes and models. We service from Key Largo Fl to Layton Fl. We have 24 hour emergency services. Rex Air is a registered State of Florida licensed contractor. We are licensed and insured.

"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."

Heating and Air Conditioning questions, answered by experts

Yes, AC coil cleaning is definitely worth it. Cleaning your AC coils ensures your AC unit will function efficiently for the long term. Dirty and grimy AC coils make your unit work harder to cool your home, resulting in higher electric bills. Additionally, having your coils professionally cleaned regularly will reduce the possibility of extensive maintenance and repair costs.

The time it takes for an air conditioner to dry fully after cleaning depends on the unit's size and humidity levels. Most units will dry within two to four hours after cleaning, but check the manufacturer's recommendations for drying times. Make sure to leave the unit off until it's completely dry.

Ceiling fans can be a great way to cool your home without the expensive utility bill of running an air conditioner. Plus, ceiling fans can sometimes run in both directions, pushing hot air down in winter and pulling cold air up in summer. With that said, air conditioning might be the only thing that helps if you live in a very warm climate.

You need to know the square footage of your home first. Multiply that number by 20, which will get you the BTUs (British Thermal Units) needed to cool your home efficiently. Homes up to 1,000 square feet usually need a 1.5-ton unit; homes 1,000 to 1,200 square feet usually need a 1.75-ton unit, and homes 1,200 to 1,400 square feet usually need a 1.9-ton unit. Talk to a local pro for more specific advice on your home. 

Yes, adding central air can increase your home value by as much as 10%. Generally speaking, prospective buyers prefer a central AC system over a ductless system or room-by-room AC units. That’s because central air conditioning blends into the home easier than individual room air conditioners and typically has less equipment to maintain.
