Here in Suffolk County, NY, ductless mini split heat pumps have become increasingly popular in both residential and commercial settings. While mini splits are known for their easy installation, they are technically advanced, and require a trained professional to troubleshoot and repair. Central Air Systems, Inc. is a Mitsubishi Diamond contractor, and we have invested in the training necessary to professionally repair and maintain ductless mini split heat pumps from all current manufacturers.

More than a few HVAC contractors and builders now install ductless mini split heat pumps, but only a handful have the training and experience necessary to competently repair them. For years we have featured Mitsubishi Ductless mini splits, but we service all brands including Carrier, Daikin, Fujitsu, Samsung, and Trane. Our EPA (Environmental Protection Agency) certified and factory trained technicians guarantee service on time, done right and priced right. We offer emergency heating repairs for both residential and commercial applications.

Do You Need Our Help with Mini-Split Service?

Practically every week, one of our heat pump specialists arrives on a service call only to find out that the problem was simple and might have been easily corrected by the owner. Before you call us, if you check these items you might save the time and expensive of a professional service call:

Remote Control Batteries

  • If your mini split heat pump uses a hand-held remote, check, and perhaps change the batteries.

Check Operating Mode

  • Check to make sure your system control is set to the correct mode: generally "Cooling" in summer and "Heating" in winter.

System Calling for Heating or Cooling?

  • Make sure that at least one zone is set to on and the desired temperature is set well below ambient for cooling operation, or well above ambient for heating operation.

Is the Power On

  • Check your circuit breaker and your outdoor unit disconnect to ensure that you have not had a nuisance trip and your heat pump system does have power.

Is the Outdoor Unit in Defrost Mode?

  • If you are operating in the heat mode, make sure that your system is not in “Defrost” mode. If it is, "defrost" should complete within a few minutes and heating operations should then resume.

Time Delay

  • If your breaker was off, after turning the power on, give it a few minutes: many systems have a built-in time delay.

Air Filters

  • Check your indoor unit filters. If your filters have not been cleaned lately, clean them now.

Mini Split Heat Pump Repair Issues

We firmly believe that ductless mini split heat pumps are a great choice for Illinois homeowners and businesses. The most common service issues are caused by improper installation or lack of proper maintenance. Common mini split heat pump service issues that require professional help include:

Installation Issues

  • Reduced or declining system capacity caused by refrigerant line leaks or mechanical damage.
  • Condensation leaks from indoor units typically cause by indoor units being installed out of level or improperly install condensation lines.
  • System or a zone fails to start due to refrigerant loss.
  • Inconsistent temperature or wide temperature swings often cause by improper system or zone sizing.
  • Wintertime outdoor unit freeze-ups cause by improperly mounted outdoor units. Outdoor units need to be high enough so that snow and ice will not accumulate around its base and impede proper operation.

Maintenance Issues

  • Changes in heating or cooling capability over time often caused by dirty indoor filters or coils
  • Capacity issues caused by a dirty or clogged outdoor coil.
  • Noisy operation indoors or out.
