Even a well-maintained central furnace and air conditioner can struggle to keep every corner of a Michigan house comfortable. Upstairs bedrooms, bonus rooms over the garage, sunrooms, and historic homes without existing ductwork often end up sweltering in July and freezing in January. At Don’s, our HVAC team dedicates 100% of its focus to residential installations, replacements, and service calls rather than new construction projects. Focusing exclusively on existing homes allows us to help homeowners across Davisburg, Clarkston, Waterford, and the surrounding Oakland County communities solve tricky comfort problems fast.
Modern ductless mini splits deliver targeted heating and cooling directly into the rooms that need it most without tearing open your walls to run bulky sheet metal ducts. When you consult our team for mini splits installation in Metro Detroit, our technicians evaluate your room dimensions, window exposure, and insulation levels to design a single-zone layout or complete multi zone ductless systems tailored to your house. You receive clear, upfront pricing options before any work starts, backed by our one-year workmanship guarantee.
Homeowners across Metro Detroit turn to ductless mini splits and heat pumps when extending central ductwork is impractical or too expensive:
Second-Story Bedrooms & Bonus Rooms: Heat rises in the summer and escapes through the roof in the winter, leaving upstairs spaces and FROG (Finished Room Over Garage) layouts uncomfortable while the main floor thermostat reads fine.
Three-Season Sunrooms & Home Additions: Adding a single-zone wall unit turns a chilly sunroom, enclosed porch, or new family room addition into a true four-season living space without overloading your existing furnace or central AC.
Older Homes With Boilers or Baseboard Heat: Houses heated by hot water radiators, boilers, or electric baseboards lack the ductwork needed for central air. High-efficiency ductless mini splits provide cooling and supplemental winter heat while keeping your original plaster walls and woodwork intact.
Home Offices, Finished Basements & Workshops: Independent temperature controls let you heat or cool the specific room you’re working in all day without paying to condition unoccupied areas of the house.
Detached Garages, Pole Barns & Guest Suites: Because ductless mini splits don’t connect to your home’s main ductwork, they safely heat and cool garages or workshops without circulating vehicle fumes or sawdust into your living areas.
Here is a catch many homeowners run into when getting quotes: most traditional HVAC companies aren’t licensed to run the new 240-volt dedicated circuit from your main breaker panel to the outdoor condenser unit. They set the indoor wall cassette, then tell you to hire and pay a separate electrician to finish wiring the system before it can be turned on.
Because Don’s has served Metro Detroit as a licensed, full-service electrical contractor since 1989, our team handles the entire setup from start to finish. When installing ductless mini splits, we mount the indoor air handlers, braze and pressure-test the copper refrigerant lines, install the dedicated circuit breaker in your electrical panel, mount the weatherproof outdoor disconnect box, and wire the complete system on the same day. You deal with one trusted local crew, one clean invoice, and one unified warranty.
Alongside new installations, we perform residential service calls and annual cleaning checks to maintain all of your heating and cooling equipment. Because wall-mounted air handlers sit right in your living space and circulate air continuously, keeping their internal components clean is essential for healthy indoor air and quiet performance.
Call our team for fast ductless heat pump repair if your system shows any of these warning signs:
Water Dripping Down the Indoor Wall: A clogged condensate drain line, kinked drain tubing, or failed mini-split condensate pump can cause moisture to back up and overflow from the indoor wall cassette.
Musty Odors or Weak Airflow: Dust and moisture buildup on the internal blower wheel (squirrel cage) and reusable mesh filters restrict airflow and create unpleasant smells when the unit runs.
Blinking Error Codes or Unresponsive Controls: Communication faults between the indoor and outdoor circuit boards, faulty thermistors, or power surges can lock out your system.
Icing Up or Blowing Lukewarm Air: Low refrigerant levels from a flare fitting leak or a faulty reversing valve prevent the heat pump from switching properly between heating and cooling modes.
During a seasonal cleaning check for your ductless mini splits, our technician washes the reusable air filters, cleans the delicate indoor evaporator fins and blower wheel, flushes the condensate drain line and pump, inspects the outdoor condenser coil, and tests electrical connections and operating pressures.
Installing ductless mini splits is clean, minimally invasive, and typically wrapped up in a single day:
Placement Walkthrough & Floor Protection: We confirm the exact indoor wall mounting spots and outdoor condenser location with you before laying down protective floor runners.
Mounting the Indoor Air Handler: We secure the heavy-duty mounting bracket to your interior wall studs and drill a neat, three-inch opening through the exterior wall.
Running the Line Set & Protective Hide-A-Line Cover: We feed the insulated copper refrigerant tubing, communication cable, and condensate drain line through the wall sleeve, sealing the penetration completely against drafts and pests, and enclose the exterior lines in a clean, weather-resistant protective casing.
Setting the Outdoor Heat Pump Condenser: We mount the outdoor unit on an elevated wall bracket or composite pad above the Michigan winter snow line so snowdrifts won’t block airflow.
Dedicated 240V Electrical Hookup: We run the dedicated electrical circuit from your main panel, mount the outdoor service disconnect box, and wire the indoor and outdoor units to code.
Nitrogen Pressure Test, Vacuum & Commissioning: We pressure-test the flare connections with dry nitrogen, pull a deep micron vacuum to remove moisture from the lines, release the refrigerant, test heating and cooling modes, clean up our workspace, and show you how to use your remote or smart app controls.
Dispatched directly from our headquarters at 10891 Dixie Highway in Davisburg, our team installs, repairs, and maintains multi zone ductless systems and single-zone units throughout Oakland County and nearby communities:
Take control of stubborn hot and cold spots in your home with whisper-quiet, energy-efficient ductless mini splits installed by licensed mechanical and electrical pros serving our community since 1989.
Yes. Modern cold-climate inverter heat pumps are engineered to extract heat from outdoor air even when temperatures plunge well below zero. Installing the outdoor condenser on a raised stand above the snow line allows cold-climate ductless mini splits to provide reliable, energy-efficient heat all winter long.
A single-zone setup pairs one outdoor condenser with one indoor wall unit to condition a specific room or open area. If you want to control temperatures across several bedrooms or living spaces, multi zone ductless systems can connect up to four or five individual indoor air handlers to a single outdoor unit, giving each room its own thermostat setting.
Homeowners should rinse off the removable mesh air filters inside the indoor wall unit every four to six weeks during heavy use. Beyond filter rinsing, you should schedule a professional cleaning check once a year so a technician can deep-clean the internal blower wheel, flush the condensate drain line, and inspect the outdoor coil and electrical connections.
