"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

Window ACs use 500 to 1,400 watts per hour of electricity, while mini-splits use 500 to 700 watts per hour. However, if you need to cool multiple zones in your house, your mini-split can use as much as 2,000 watts per hour. How often you run your system will impact how much electricity you use (and how much you pay per month).

Some AC filters, known as reusable filters, can be cleaned and reinserted. Most AC filters, however, are disposable and cannot be cleaned. 

Condensation forms when warmer, outside air combines with cooler air in your ductwork. This can happen when there are leaks in your air ducts, your HVAC system has a dirty air filter, or there’s a lack of insulation around the ducts. To prevent it from happening, replace your HVAC filters as directed. Also, once every five years, hire a local air duct cleaner to clean and inspect them.

Choosing a unit with higher BTUs can use more electricity if the BTUs are more than what’s necessary for your room size. However, choosing an AC with BTUs that match the size of your room or house, your unit will cool your space efficiently. On the flip side, choosing a system with not enough BTUs can cause the system to work harder to try to cool the space, leading to more electricity consumption and higher energy bills.

If your whole house is cold that’s one thing, but what if you only have a few rooms that are cold? First, you need to determine why this may be happening. A good place to start is to investigate the potential causes listed in this article—heat transfer, airflow, thermostat problems, humidity, and insulation. Once you’ve narrowed down the issue, you’d apply the same principles to the cold rooms as you would to the entire home.
