Mini splits exist for the rooms central air forgets. The garage workshop, the sunroom that turns into an oven by midafternoon, the addition the ducts never reached, the Dearborn Heights house that was built without ductwork at all: each of these can be heated and cooled on its own by one or more wall-mounted heads. A slim line set carries refrigerant, power, and condensate drainage through a single three-inch wall penetration to the outdoor unit, so there is no duct system to leak. The inverter compressor speeds up and slows down with the load rather than cycling hard, which keeps the room steady, quiet, and cheap to run. In winter, the same equipment works as a cold-climate heat pump, not a cooling unit pretending to heat.
Most of our service calls are for AC Repair. Start there if your system isn't running right.
Warning Signs for Ductless Mini Split Installation
Recognizing the warning signs early can save you time and money. Watch for these telltale signs:
- A house built without ducts, with no practical path to add them
- Constant thermostat battles over whose room is too hot or too cold
- Heating costs driven up by resistance heat in rooms the furnace misses
- A wish for room-by-room control rather than one thermostat for everything
- Noisy window units you are done lifting in every spring
- A room or addition your central system has never conditioned properly
- An ADU, in-law suite, or remodel that deserves its own heating and cooling
- A workshop or bonus space you want comfortable in every season
Don't Wait for a Total Failure
Left unchecked, even a small fault or temperature swing often signals a system working its way toward a breakdown. If you notice any of these signs, call (313) 251-4079 for a prompt inspection.
