AAA Sub-Zero Inc

Great customer service, quick response. Kenneth is great guy to deal with, polite & professional. Highly recommended.

I have a turn of the older craftsman house in Key Largo in which I was process of replacing all of the existing Air Conditioning and unfortunately had initially hired the wrong company. I was left with a half installed HVAC that the inspector marked on the corrections sheet a very long list.
So I called AAA Sub Zero as they are certified and listed right on their site. They came right out and assessed the corrections and what needed to be done to get it done right. He explained very clearly where the issues were. He offered a very good price, but more importantly quality installation that would pass code. They removed the problem items with the old HVAC system in a couple days.
So I called back the inspector, PASSED! What a weight was lifted off me — and if you dealt with city Inspectors, you know what I mean. Awesome job and very cool guy, I couldn’t thank him enough. They have my business for life.

AAA Sub-​Zero saved my sanity when my AC went out. Thursday morning, I contacted 3 companies, including AAA Sub-​Zero. That same morning, Charles Rumpf, senior staff engineer, came by, took at look at my unit and said, «This is pretty straightforward. We can get it replaced Friday.» The next day! What a blessing! As I work from home, having no AC was killing my productivity. His crew came by Friday morning and by 4 p.m. that day, my house and office were cool again. His bid was in the middle of the three quotes I received, but there was no question about giving him the job. The value I received — including the superior customer service — made it the absolute best deal of them all. Not only that, but his annual service fee is considerably less than his competitors. I would recommend AAA Sub-​Zero to anyone who wants fast, friendly and efficient service. And a cool house/​office!

Mr. Charles, don’t worry Houston Refrigeration in Islamorada fixed the problem in 1 hour. They are very professional, they have good knowledge about commercial refrigerators, they do work in all grocery stores and good restaurants in our area.
Besides of that it was wonderful to deal with honest people.

Fire hazard and poor workmanship. I Contacted aaa subzero in early March to get a new air handler and new duct work installed. The tech/​installers came out to install and seemed to have no idea what they were doing. They wanted to replace all existing duct work with 6″ flex duct that had only an R4 value. After telling the guys how to do there job and expecting the same or better quality ducting I realized that the installers had no idea what they were doing they spliced R6 with R4 flex duct, used boots (the thing in the wall the duct connects to) that were smaller than existing, used non metallic duct tape, used no cable ties, used no mastic around collars at boots, they may have used collars at the plenum but just stuffed a few ducts into the plenum box allowing for no airflow. They used the wrong size Y for splitting a 10″ duct into two 8″ ducts. Some boots were not even hooked up in turn cooling the attic. To top it all off they tried to leave with out reinstalling the float switch at the drain line or the pan when I insisted they replace that they be grudgingly did except they didn’t even hook them up! They just shoved the wires in the air handler. Worst of all the tech doing the installation incorrectly wired the heater in the air handler. He used #10 stranded wire instead of a # 8 the amount of amps drawn through those wires would have created a fire! Another company came into to repair all of the terrible work that was done by AAA sub zero and said it was the worst work they have ever seen. If your shopping around for hvac work in the keys go with houston air or another reputiable hvac contractor not aaa sub zero, they put the HAC in HVAC

During July, 2011, I paid 3646.00 to AAA Sub-​Zero for the installation of a new Rheem/​Ruud AC unit. I chose this company for two reasons: 1. Lowest estimate for the necessary work. 2. the only company I could find that would do the installation within 2 days. In the extreme heat of that July, I was desperate for AC.
Before installation, I was informed by Charlie Rumpf, owner of AAA Sub-​Zero, that the unit being installed was the right size for my home. The old was a two ton, and he insisted that a 4 ton would be perfect.
After installation, I began having extreme issues with condensation. I discovered it when the moisture from under the house was coming to the surface of the sub-​flooring. At the time of the AC installation, I was having all of the sub-​flooring replaced in my home. I was able to remove a piece of the sub-​flooring and found pools of water on the duct work. It is also then when I realized the duct work had not been replaced during installation of the new AC unit. Most of the insulation around the duct work was so saturated with water that it had fallen off, and in turn, the vapor barrier was pulled loose and laying on the ground.
Charlie Rumpf of AAA Sub-​Zero had installed an AC unit that was too large for the original duct work. Because the ducts had not been replaced with the AC installation, I then had a serious moisture problem. Charlie’s son arrived to replace duct-​work, and then months later, I find out that, according to Charlie, he was not aware of his son doing any work! I had already paid another $ 5,900 for replacement duct-​work and spray foam insulation. The duct work WAS NOT replaced. The insulation was not properly sprayed. The subcontractor had no idea what he was doing! I called Charlie, and he said that he had no idea that his son had completed any work. The problems continue.
On Monday, Feb. 10, 2014, the AC stopped working! I immediately called Charlie, AAA Sub-​Zero, and he told me he would take care of it first thing in the morning. Someone arrived just before NOON on Tuesday, Feb. 11. At that point, it was 90 degrees in my home.
About an hour later, the service technician presented me with a bill for $ 650 for a blower motor and its installation. I was charged for labor and parts. Charlie insisted that the part was not covered by the ten year warranty. I refused to make the payment, so Charlie Rumpt told his worker to remove the new, presently working motor. The technician removed it, and then tried to leave with the broken motor. When confronted, he told me to call and get permission from Charlie!
After the departure of AAA Sub-​Zero, I called R G Mechanical, and the owner, Ray Garrido, arrived by late afternoon. He ordered the part and told me he would return the next morning to install the motor. He arrived the next morning, installed the motor, and it would not work. As Ray, checked to identify the problem, he found loosened and cut wires, along with a wire to a FKEC box that had never been reconnected since the unit was first installed in 2011! The connection was stuck to some of the spray foam insulation.
AAA Sub-​Zero has been and continues to be a nightmare. I believe that Charlie Rumpf is a con artist who uses his business as a cover for his crimes of deceit and thievery.
I strongly recommend that anyone who needs AC or heating work completed stay far, far away from AAA Sub-​Zero!

Expensive! did not provide an estimate and charged over $ 1500 to change a couple of $ 15 capacitors and recharge freon… Blamed the people who did the wiring of the unit… Turns out they installed the unit in 2007.
