As president of John C. Cassidy Air Conditioning, Inc., John Cassidy, Jr. has more than 30 years of experience in the residential and commercial air conditioning business. He has helped to build a strong and highly-respected company with a reputation for providing quality products and services to our community.
Jack started John C. Cassidy Air Conditioning in 1960 on the dining room table of his home he shared with his wife, Mercedes, and their five children. Jack set the bar high for both himself and his new company, instilling a lofty corporate philosophy to always be honest and conduct business with integrity.
At John C. Cassidy, we believe that regular professional preventive maintenance of your cooling and heating system is the most important thing a home or business owner can do to ensure longevity and operational efficiency. All brands of air conditioners provide more comfort and stand a better chance of longer life and efficient operation when regularly maintained.
Modern comfort control systems are usually equipped with surge protection. In the event of lighting, however, it's never a bad idea to turn off your air conditioner and unplug appliances. Check your filter at least monthly and clean and replace as needed. A dirty air filter limits airflow, which can cause the compressor to run longer, cause the heat exchanger to overheat and increase utility bills up to 20 percent or more.

Cassidy has for years serviced my a/c quarterly. They show up on time and do a very thorough job. The unit is over 17 years old, and I had them replace it last Friday, both the air handler and compressor, with a Carrier. They did the entire job-removing the old unit/installing the new one, with a new thermostat in 4 hours. It works perfectly. When the job was finished, a quality control tech came out inspected the installers' work. Impressive!

Left a message on Sunday evening saying to call us Monday. They returned our call Monday am. They were out repairing our air unit before lunch. Christian was very knowledgeable and repaired our unit in no time

Reinaldo at Cassidy air conditioning could not have been more professional. On time, knowledgeable, competitive price- they delivered what they promised. I'd use them again in a heartbeat.

I highly recommend Cassidy AC. John and all his team members including the techs who came to the house for service and installation, and the office staff were excellent. Our comfort advisor Mike was excellent. Service: Install AC

So, I interviewed three air conditioning companies for a new AC installation in my townhome. When Rinaldo came out to the house, he was friendly, professional, sincere, and followed up several times while we were making a decision. He was neither pushy nor off-putting, and his knowledge and mannerisms made me feel I was making the right choice. On installation day, I had two hard-working and very nice technicians.

They answered my questions, were careful of the carpet, floor and walls and worked efficiently. Rinaldo came by to check on the progress (awesome!). Upon completion, another gentlemen came by to give his "stamp of approval". He apologized for me having to wait for him, when I honestly did not think he took that long to come over. All in all it was such a pleasant experience! But, I have not told you the best part.

I had an installation date (right smack in the middle of Christmas week by the way) and when my old AC starting leaking fiercely, Cassidy was able to move my installation up over a week to accommodate my situation! I will definitely recommend them. Kind regards, Lisa Keough

Stay as far away from this company as possible. On July 27 I called them to come and repair the work that they had done which had failed within three months. I spoke with the service manager and he advised me that they would waive the diagnostic fee of $95 since they had just been out to repair my air conditioner less than three months prior. They did not repair the air conditioner the second time they came out I did not let them do the work.

They tried to charge me double what I was quoted by Another reputable air-conditioning company. Fast forward to today I received a letter in the mail from a law office saying that they are suing me for the $95 diagnostic service charge. These people are crooks and are terrible to do business with. I left messages for them about the $95 charge over two months ago when I received a bill in the mail. They never called me back. There are tons of air conditioning companies in Florida any single one of them is better than John C. Cassidy

Martin (Sales) Definitely deserves huge props for not only his professionalism but also he's extremely knowledgeable in this field. He not only writes up deals and gives estimates in a prompt and timely manner he also comes directly to your home to make sure all has been installed to your specifications. He's easy to reach via phone email or text.

He puts care into your concerns first always and I so appreciated that so very much. He has integrity and he is humble as well. We had a complete air conditioning system installed. John C Cassidy Air has been or go to for several years. They're service is top notch and dependable! Laurie and Jan ( Covered Bridge) Lake Worth Florida

Do NOT use them! My AC kept blowing warm air, and I had to call John C. Cassidy three times over the course of 4 months. Now the same issue is happening gain (in less than a month from the previous visit). I paid over $1,500 in fees to clean the pipe. My AC unit is only 2 years old, was installed by technicians from John Cassidy, and they can't explain why the issue keeps reoccurring or how to fix it.

When I called them again, I was told that they can schedule a visit in 24 hours. I have a small baby at home, and it's over a 95-degree-heat in Florida. How can I wait for 24 hours? This is the most unprofessional and careless organization I have had to deal with in my life. I won't be using or recommending this company ever again! Shame of you for running such a dishonest business!

Cassidy A/C electric installed a new Bosh 14.20 EER 24,300 air conditioning unit in our condo. The quality of service was excellent and I am very happy with the finished product. Their salesman Mike Banks went above and beyond in helping us during the entire Install. He is a definite asset to the John C Cassidy company. I highly recommend this company to anyone that needs HVAC services, maintenance and/or repair.
