ductless mini split air conditioningOne of the easiest ways to add a cooling system to an existing home is by installing a ductless mini split air conditioning system. Unlike central air conditioners, these systems do not require a duct system and they use only a small conduit to connect the indoor and outdoor portions. Today’s ductless mini split systems are extremely efficient and offer many great innovations and features.

Variable-Speed Compressors

In many conventional air conditioners, the compressor runs at a single speed, and can only switch on when the temperature becomes too high, and switch off when the desired temperature is met. This can be inefficient and cause excess wear on the system’s compressor and other components, while creating unnecessary temperature swings between cycles. Variable-speed inverter compressors can run at any speed, allowing the system to adjust the cooling capacity precisely to the current conditions, which increases the system’s efficiency and keeps your home comfortable regardless of the temperature outside.

Variable-Speed System Fans

Like the variable speed-compressor, variable speed fans on the condenser and evaporator coils allow the system to better adjust the cooling capacity to current conditions, and they reduce the energy usage of the system. In addition, when the evaporator fan is allowed to run at slower speeds, it makes the system much quieter and reduces noise levels in the room where the indoor unit is installed.

Efficient Coil Designs

Specially designed coils maximize the heat-transfer surface and increase the efficiency of the transfer process. Improved R-410 refrigerant also helps increase the efficiency of the coils, while protecting the environment.

Improved Control Systems

Efficient control systems use multiple sensors to detect current conditions and adjust the output accordingly. Advanced remote controls allow you to control your ductless mini split air conditioning system from a distance, and some systems can even be controlled remotely from the Internet.

With all these advances, today’s ductless mini split air conditioning systems are about twice as efficient as older models. To learn more about mini split systems, contact our team at Conditioned Air today. We serve Southwest Florida, including the Sarasota, Ft. Myers and Naples areas.


Air Conditioning ProblemsOne of the most common air conditioning problems in South Florida is a frozen evaporator coil, which happens when the evaporator coil cannot absorb heat correctly and its temperature drops below freezing, turning any condensed moisture on the coil into ice. Not only does this prevent the system from cooling properly, it can also cause permanent damage to certain components. To get the system running properly, you will have to determine the cause, correct it and thaw the coil.

Airflow Problems

In many cases, poor airflow can prevent the coil from absorbing the heat in your home, allowing it to freeze up. Reductions in airflow can be triggered by a dirty or clogged air filter, an obstructed supply or return duct, or problems with the blower fan. Replace the air filter, if necessary, and check your air ducts for obstructions. Make sure none of the vents are covered by furniture, curtains or other items. Check the blower fan and make sure that it is relatively clean and operating correctly, and that its belt is not damaged or slipping.

Dirty Evaporator Coil

Household dust, pet hair and other debris can accumulate on the evaporator coil over time and prevent it from absorbing heat properly. If your evaporator coil is excessively dirty, allow it to thaw, then clean it gently using a soft brush and a vacuum cleaner, being careful to not bend any of the delicate cooling fins.

Refrigerant Problems

Low refrigerant levels, leaks or a clog in the lines can also cause major air conditioning problems like freezing. To correct a refrigerant problem, or any other serious issue, you will need to call a professional.

Thawing the Coils

To thaw the evaporator coils, turn off power to the system and allow the ice to melt naturally. To speed things up a hair dryer or heat gun can be used in a pinch, but never use tools to remove ice, as they may damage the refrigerant lines.

AC NoisesAn air conditioner that isn’t working properly can be a cause for concern, but it shouldn’t make you panic. Sometimes a few simple troubleshooting steps can let you resolve the problem and get the system working again without the need to call for repair. Here are a few things to look for when troubleshooting air conditioner problems and A/C noises.

A/C Doesn’t Work

  • Check the power supply to the air conditioner and make sure it is plugged in and receiving power.
  • See if the circuit breaker controlling the A/C has tripped. Reset the breaker and see if the air conditioner comes on. If the A/C unit keeps tripping the breaker, there may be an electrical problem that needs to be fixed.
  • Make sure all vents and registers are open and free of blockages from furniture, boxes, clothing, or other objects that could restrict airflow.
  • Make sure the thermostat is working and that the temperature and operational settings are appropriate for the season. Change the batteries in the thermostat if necessary.

A/C Noises

  • Rattling or clattering noises coming from your air conditioner could be the result of an access panel or other cover being loose.
  • If you detect new or unusual A/C noises, give the system a short period of time to operate and see if the noises continue.

A/C Produces No Cool Air

  • If the fan is working, make sure that the system hasn’t been set to fan-only operation. Set the system to “cool” if necessary.
  • Listen to make sure the compressor is working and that coolant is being circulated through the system.
  • Check the HVAC system ductwork to ensure that there are not damaged or missing sections and that all sections are fitted tightly together. Each connection should also be sealed with mastic, a specialized sealant, or with metal tape.
