"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."

"The BEST company that I have ever had the pleasure of dealing with. My central a/c unit was not working and I decided to install a split unit in place of the central unit. Dustin came to my residence to do a survey. While there, he completed the estimate for installation of the split unit. He also did a thorough check of my inoperable central unit and determined the problem. He gave me a repair estimate that was 50% lower than two other estimates from other a/c companies. In addition, Dustin coordinated with a provider to ship the needed part (coil unit) the next day!! We had been without a/c for almost two weeks in the sweltering FL heat! What two other companies failed to repair/resolve, Dustin did! My family and I are greatly indebted to Dustin and his company for a superb job and customer service relationship. I strongly recommend Dustin and his company for any a/c problem! Again, excellent customer service, technical knowledge and superb people skills."

"I just DIY installed my brand new ComfortStar 12,000 BTU 20 Seer 2 last night in my car garage. The installation went well and the mini split was impressive in quietly & quickly cooling a 2 car garage. The next morning the cool from the AC got warm. There was a leak throughout the night and by the afternoon when no cool air was given. I starting looking online to find R410A frigerant to pickup near me. I found out that R410a is to be discontinued with the exception of ordering online…with delivery time & no immediate replacement. I reached a few local HVAC techs but appointments were a day or two later. Adrian Cooling & Heating LLC’s & Arlet answered my distress call. A few hours was all it took with a friendly & knowledgeable tech to diagnose, refill refrigerant(2lbs) & checked to make sure no leaks. Bravo, an amazing rescue and my much needed work to be done in my cooled garage is very appreciated. I have all good praises from the reassuring phone convo w/Arlet & Adrian Cooling & Heating’s competent tech! I will only consider them if in need. Absolutely high regards & recommendations with my entire experience and shockingly fair in service fees. My Pop’s assumed “Emergency” fees would double or triple…refrigerant fee was the only invoiced!!! Thank you so much! Rouel"

"This job was very dificult due to the existing structure but they handled it very well. The owner even had his son to crawl thru the ceiling rafters to run the ducting! Everything came out very well. I would heartily reccomend them!

Air Conditioning FAQs, answered by experts

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

To keep your air conditioner in good working condition, you should have it serviced by a professional at least once per year, ideally in the spring before the cooling season begins. If your AC unit is 10 years or older, consider servicing it twice a year (once in the spring and once in the fall) to catch potential problems early and help it reach its full lifespan. During a service visit, a technician will inspect, clean, and replace parts as needed. Regular maintenance helps avoid costly repairs. As a DIY task, you can also clean the evaporator coils annually.

Yes, you can clean AC coils yourself. Just make sure that the power to your AC system is off before you begin. You’ll need some basic tools and supplies, including a soft brush, cloth, screwdriver, and a commercial or homemade cleaning solution. Cleaning your coils will only cost about $10.

There are ways to detect a refrigerant leak with several different testing methods. However, most homeowners can figure out something’s wrong with their AC unit by noticing these common signs:

  • Ice forming on the evaporator coil

  • Water leaks near the AC unit

  • Frequent hissing sounds

  • Increased electric bills

  • Unit takes longer than usual to cool

  • Unit is blowing hot air

You might notice that your air conditioner isn’t running as effectively as it once did. Specifically, your AC unit could take longer to cool your home, or it might struggle to remove humidity from the air. Higher utility bills and hissing sounds coming out of your AC could also indicate a leak.
