"Did a great job on cleaning our dryer vent and did an inspection on our air ducts. The quote I received on cleaning the air ducts was extremely high. I went with another company that was 1300 dollars cheaper."

"The service tech who serviced my central air conditioning unit on 7/16/21 was Nick with Florida Home Air Conditioning. Nick was professional and very knowledgeable about what needed to be done. And â ¦ he was respectful and mannerable which I appreciated. If I could, I would request Nick for all of my air conditioning maintenance needs. Regards. A. Brady"

"Highly recommend CJ Vickers of Nassau Duct Cleaning who cleaned our dryer duct this morning. Best we’ve ever used anywhere we’ve lived. Showed up 5 minutes early. Very polite & professional. Used a camera to first scope the duct for any breaks, gaps, or obstructions. Cleaned the duct & dryer, & surrounding area then put everything back in place. They do more than dryer vents. Highly recommend. Nassau Duct Cleaning (CJ Vickers) (904) 753-1682 (904) 654-8403"

Air Conditioning questions, answered by experts

Yes. It's normal for the AC compressor to cycle on and off intermittently in dry mode as it maintains the desired humidity level. The compressor cycles to prevent over-dehumidification and to maintain a comfortable indoor environment. This cycling behavior ensures efficient operation and optimal humidity control, contributing to the overall effectiveness of the dry mode function in your AC system.

A blocked return air vent can cause your HVAC system to work much harder and, therefore, less efficiently. The result is higher utility bills and poorer air quality. A blocked return air vent can also cause unpleasant dust, dander, and odors to linger in your home’s air.

Yes, mini-split systems are generally less expensive to run than central air conditioners and are significantly more energy-efficient. Because mini-splits do not rely on ductwork, they avoid the energy loss associated with ducted systems, allowing cooled or heated air to reach its destination more efficiently. Additionally, they offer zoned control, meaning you can run units in individual rooms and turn them off in unoccupied areas. This capability can lead to energy savings of about 30% compared to a central air system, resulting in a lower monthly energy bill.

Mold in your air conditioner isn't a good thing, as it can be harmful to your health. If the mold travels through the ductwork or is blown out of the A/C, you and your family can inhale mold spores and develop respiratory illnesses and other problems. Preventing mold from growing in the air conditioner will help protect your health.

AC evaporator coils should be cleaned at least once per year to keep your unit in good condition. For optimal performance, consider cleaning them twice a year—once before and once after the main cooling season. More frequent cleanings may be necessary for older systems, units with performance issues, or those in climates with high levels of humidity, dust, and dirt.
