My A/C called my home to 71 last night. I raised the temperature to 77 this morning. Akeem Notified me that the compressor was not winding and must be replaced because it will not cool. I am very confused by this. Compressor and air conditioner were purchased new May 10, 2024, my third new A/C from Cassidy. My
Grade for this service is not a personal reflection on Akeem, He is polite and personable But I do not understand the sudden disruption of service as explained above.

Akeem S. is an awesome HVAC Tech.
He obviously knows what he is doing, he's very well spoken, clean-cut and respectful to James and I, and our home.
We had U.V. lights and a condensate "I.V. system" installed by Akeem on both our residential HVAC systems, he explained everything to us in a very detailed manner.

I wanted to take a moment to recognize Christopher Andramuno for the excellent service he provided. He was professional, respectful, and very knowledgeable throughout the entire maintenance visit. He took the time to explain everything clearly, worked efficiently, and made sure the issue was fully resolved before leaving.
It’s always appreciated when someone not only does their job well but also shows genuine care and great customer service. Thank you, Christopher, for your hard work and for making the experience smooth and stress free. Highly recommend!

Did not know what he was doing, put a new thermostat and thought it was working when in fact, it had not been properly programmed.
Had to call back a technician for the following day.
Sloppy in appearance tried to sell things spent most of the time on the telephone trying to figure out the thermostat at which he failed.
Probably a nice guy, but definitely needs a lot more training
Frequently Asked Questions About John C Cassidy Air Conditioning & Plumbing
How often should I service my AC?
Professional AC maintenance should be performed twice yearly - before summer and winter seasons. Regular tune-ups prevent breakdowns, improve efficiency, and extend your system's lifespan in Florida's demanding climate.
Why is my AC running but not cooling?
This often indicates dirty filters, low refrigerant, frozen coils, or thermostat issues. Professional diagnosis is essential since multiple components could be involved, requiring different repair approaches.
How quickly can you respond to emergencies?
We provide 24/7 emergency service throughout Palm Beach County with rapid response times. Our experienced technicians carry fully stocked trucks to handle most repairs on the first visit.
When should I replace my water heater?
Most water heaters last 8-12 years. Replace yours if you notice rusty water, strange noises, frequent repairs, or inconsistent temperatures. Tankless units offer longer lifespans and energy savings for Florida homes.
What's included in preventative maintenance?
Comprehensive inspections cover electrical connections, refrigerant levels, filter changes, coil cleaning, and performance testing. Regular maintenance prevents 95% of system failures and maintains manufacturer warranties.
