"Ozzy was excellent. He was punctual, professional and fixed the problem. He gave me advice on how to keep the AC unit in top shape. I kept his phone number and will use him for all my AC maintenance and recommend him to anyone having AC issues."

"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

It is possible to add air conditioning to an older home, but it can be very expensive to do so. Expect to pay anywhere from $6,000 to $17,000 or more for the ductwork and AC unit. You’ll also have to hack into the home’s walls and ceilings to add ductwork, which can impact the aesthetics of an old home.

Your heating and cooling systems cost you the most on your electric bill and make up 50% of your bill on average. Your washing machine, dryer, oven, and stove contribute significantly to your electric bill as well. Lights, fans, and smaller electronics add up, but aren’t the biggest energy consumers. You can reduce your power usage by setting optimal temperatures on your thermostat and investing in energy-efficient appliances.

Yes, it’s normal for an AC to drip water. In fact, it’s part of the dehumidifying process that takes place inside your AC unit as the condensation trickles down into the drain pan. However, it isn’t normal for your AC to sound like it’s running water or have large puddles around it. If that happens, you can try the solutions listed above or call an AC repair pro.

The difference between a home surge protector and an HVAC surge protector is that an HVAC surge protector is designed to protect the components inside your HVAC unit while a home surge protector is installed near appliances and meant to protect your entire home. There are three tiers of whole-house surge protectors, and they are more expensive to install than HVAC surge protectors.

Yes, it is possible. An electrical fire can break out if the compressor has inadequate ventilation. When it overheats but doesn't have a proper thermal cutout, this can cause the motor to short-circuit and catch fire. This risk is exacerbated if flammable materials, like dust and fallen leaves, are clogging the unit. The compressor overheating won't start a fire by itself, but poor maintenance and installation can increase the risk once it hits its breaking point and short-circuits.
