"I could not ask for a better experience. Cool-R-Us was professional throughout the project. Its salesman quickly submitted a proposal, and offered a fair price. The company included an extended warranty. The technicians arrived on time and efficiently and neatly installed the split system. Operation was simply explained, as were Beaches Energy Company rebate process. I look forward to many years of worry free use."

"I highly recommend Florida Air Flow Heating and Air for air conditioning repair, zoned ac system repair, and replacement services. The owner Aldi along with his team of technicians has been servicing my ac system for years and he has replaced my system and my sister's system in the past. He always does an amazing job to get someone out to fix your system as soon as possible and his pricing for repairs and replacements is always fair and honest. I recommend Aldi and Florida Air Flow Heating and Air to all of my family and friends and I will continue to do so for the foreseeable future. Thank you Aldi for saving us from the Florida heat during the summers we really appreciate it!"

"Technicians Darius and Matt were very professional, customer-friendly, and definitely knew their trade. They identified the problem in a short time and worked diligently to find a replacement part, get it installed, and the system back on line. It’s cool to have cool air again. Thank you to Maurice and crew. Job well done"

"Elmer came out within less than an hour from the time of quote. He charged exactly what he said he would and was transparent about prices prior to making fixes. He replaces the capacitor and then turns out the outdoor motor fan was broken, he went out of his was to get us a preowned part the same day to save us some money. No one loves spending the extra money, but overall the experience was pleasant. He was professional, timely, and our AC is now up and running."

Air Conditioning FAQs, answered by experts

The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.

One of the fastest ways to unfreeze an AC unit is to turn off the unit and, if it’s warm outside, use the fan-only mode to help blow warmer air through the unit to speed up the defrosting process. While it may be tempting to use a hair dryer to defrost the air conditioner, that high heat can damage the coils.

After defrosting, if you can safely solve the issue with a fix like changing the filter, go ahead and do so. Otherwise, call in a pro before turning your AC back on.

This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn’t overflow. When you turn the system back on, keep an eye on it to ensure it doesn’t start freezing again.

Yes, a dehumidifier and air conditioner can be used simultaneously in a home. A dehumidifier can bolster an air conditioner’s efficiency. Typically, a dehumidifier is used when the air conditioner alone cannot keep a home’s humidity levels at a comfortable indoor humidity level, which should, ideally, be between 30% and 50%.

An HVAC unit, like a furnace, air conditioner, or heat pump, produces warm or hot air. The air ducts serve as the passages to help heat or cool air from the HVAC unit flow through the home. Air ducts are just one part of the overall HVAC system.
