Dunwiddie is Your Local Ductless Expert

Prior to the last decade air source heat pumps were considered as ineffective in a cold climate like here in Wells County, IN. Based on new inverter driven technology, mini split heat pump systems are now a great choice for Bluffton, IN homes and businesses in any season. We feature the extremely efficient, flexible, and comfortable ductless mini split heat pumps from industry leader Mitsubishi.

Dunwiddie Heating & AC, Inc. is a Mitsubishi diamond mini split heat pump dealer. They offer a solution to fit virtually any space. No ductwork makes installation quick, cost-effective and minimally disruptive. They are available in the following broad categories:

  • Single or Multi-zone: One indoor unit pair with a single outdoor unit, or up to 8 indoor units integrated with a single outdoor unit.
  • Heat Pump, or Air Conditioning Only: Single zone systems are available in AC only models. Heat pump systems are available in a broad range of configurations and efficiencies.
  • Indoor Unit Choices:
    • Ductless wall units: typically mount high on an interior wall.
    • Recessed Ceil Cassettes and Ceiling Suspended: Sleek and modern ceiling-mounted options include EZ FIT® recessed ceiling-cassettes that fit between standard joists, 4-way recessed ceiling cassettes, and ceiling-suspended units.
    • Floor Mounted: Wall mounted at floor level with multi-flow vanes for rapid warm-up.
    • Ducted systems: Compact horizontal ducted, or multi-position air handlers.
  • Standard Heat Pumps or Cold Weather Hyper-Heat Models:
    • Standard heat pump systems offer balanced heating and cooling. Common heating performance with 100% of the rated capacities to 5°F
    • HyperHeat offers 100% capacity to -5°F and 76% capacity and efficiency to -13°F. In many applications, even here on the northwestern side of Chicago, require no back-up or supplemental heating systems.
  • Smart Controls: Available Kumo Cloud Wi-Fi® connectivity lets homeowners adjust settings from their smartphones.

Emergency Ductless Mini Split Repair Service

If you're having trouble with your existing mini split heat pump system, Dunwiddie has invested in the training necessary to professional repair and maintain mini split heat pumps regardless of brand.

Do you need our help? 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

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.

If your mini split heat pump is fine today but you want to make sure you're ready for either winter or summer weather, consider a pre-season tune-up. We’ll schedule a complete system check to ensure your system is ready for the cooling or heating season.
