Best heating and air conditioning pros near Key Biscayne, FL

"These folks are great!  The first couple of years that I had this central AC installed, the main HVAC unit would freeze up and flood the closet and adjacent areas.  
After paying another company for the same repair for three years, I finally ditched them and called Weathershield.  They came out, noticed that I had a bad thermostat, replace that, serviced the unit and I haven't had a problem since then. 
The folks are super polite, arrive on time and have had my AC purring now for over four years now.  Can't say enough.

"Probably, THE BEST HVAC service we’ve ever gotten. Thank you, Jose for your expertise and know-how. And the customer service with the front office was top-notch and pleasant!"

"On time and very professional. The work was done efficiently and when a problem arose with the AC not coming back on (thru no fault of their own), they sent a technician to remedy the problem."

"Jose responded quickly. He was willing to help my senior mom understand the issue with the HVAC. He also showed her how to work the thermostat. He took pictures for me and made sure the job was done right."

"I had an amazing experience with Ice City AC. From the first call, they were responsive, professional, and actually showed up on time (which is rare in Miami). They diagnosed the issue quickly and explained everything in a way that made sense—no upselling, no pressure. What really stood out was the honesty. Instead of trying to sell me a whole new system, they fixed the problem and saved me thousands. The work was clean, fast, and done right the first time. You can tell they know what they’re doing. My AC is blowing colder than ever, and the airflow in my house is way better now. If you’re looking for someone reliable, knowledgeable, and fair on pricing, Ice City AC is the real deal. I won’t call anyone else. Highly recommend."
