Mini Split Cooling Services in Berkley, MI
Ductless Cooling for the Rooms Central Air Never Reached
Ductless mini splits connect the outdoor unit to each indoor head through an opening roughly 3 inches wide, which means cooling a sunroom, attic bedroom, or older bungalow without cutting into walls for ductwork. Charest Heating and Cooling installs, repairs, and maintains mini split cooling systems in Berkley, MI and nearby Royal Oak, MI, Huntington Woods, MI, and Southfield, MI. Because each head runs independently, you cool only the specific spaces your family actually uses each day.
Having worked on cooling systems for 25+ years, we plan every ductless installation around room size, sun exposure, and where the head will blow air most evenly. We install trusted equipment from Daikin and our other partner brands, route line sets neatly, and test every single zone before we pack up and leave. New system estimates are free, and repair calls reach us 24/7. Contact us through our online form to plan your mini split cooling project.

Single-Zone Mini Split Installation
One outdoor unit paired with one indoor head is ideal for a garage office, addition, or stubborn bedroom. We size the system to that room, mount the head for even airflow, and seal the wall penetration against drafts, insects, and moisture.
Multi-Zone Mini Split Systems
A single outdoor condenser can serve several indoor heads, each with its own temperature setting. We plan the zones, balance capacity so every room gets enough cooling, and route line sets to keep the exterior of your home looking clean.
Mini Split Repair
Blinking error codes, weak airflow, or a head that stops cooling each tell us something specific. We read the fault codes, test sensors and communication wiring, check refrigerant pressures, and repair the actual failure rather than guessing at parts.
Indoor Head Deep Cleaning
The blower wheel inside a wall-mounted head collects dust and can grow mold that sprays into the room. We disassemble the unit, clean the coil and blower wheel, flush the drain pan, and reassemble everything so airflow returns to normal.
Line Set Covers and Routing
Exposed copper lines and wiring can look messy running down the side of a house. We route the line set along the most direct, least visible path and install paintable covers that protect the insulation from sun damage and weather.
Condensate Drain Service
Every indoor head removes moisture that has to drain somewhere. When a line clogs or a pump fails, water drips down the wall. We clear blockages, test condensate pumps, and adjust the drain slope so water leaves the house as intended.

FAQ's
How many indoor units does my home need?
The number depends on how many separate rooms or open areas need cooling. An open kitchen and family room may share one head, while closed bedrooms usually need their own. A load calculation for each space sets the final count.
Are mini splits a good fit for older homes without ducts?
Yes, ductless systems are one of the best cooling options for older homes built with radiators or no ductwork at all. Charest Heating and Cooling installs them in many Berkley, MI houses where running new ducts would mean tearing into plaster walls.
How often should mini split filters be cleaned?
Rinse the washable filters inside each indoor head about once a month during heavy use. Clogged filters reduce airflow, freeze coils, and raise energy use, and a yearly professional cleaning handles the blower wheel and coil that filters cannot protect.
Why is my mini split leaking water indoors?
Indoor leaks usually come from a clogged condensate line, a failed pump, or a head that is not mounted level. Turn the unit off to prevent wall damage, wipe away standing water, and schedule service to clear the drain properly.
Can a mini split cool an attic bedroom or addition?
Absolutely, and those spaces are where ductless systems shine. Attic rooms and additions often sit at the far end of existing ductwork, and a dedicated head delivers cooling right where the heat builds up instead of relying on long duct runs.
How loud is a ductless mini split?
Indoor heads are quiet, with many models running around the level of a soft whisper on low settings. The outdoor unit sounds similar to a small central air condenser, and placement away from bedroom windows reduces the noise you hear inside.
Where should the indoor unit be mounted?
High on an exterior wall is the most common location, with clear space around the head for airflow. We avoid spots above electronics, behind curtains, or directly over beds where a steady breeze would feel uncomfortable during sleep.
Can a mini split replace window air conditioners?
Yes, and most homeowners notice the difference right away. Charest Heating and Cooling replaces window units in Berkley, MI homes with ductless heads that run quieter, lock more securely, cool more efficiently, and free up the window for light and fresh air.
Why Choose Us for Mini Split Cooling Services
Placement That Makes Sense
A mini split mounted in the wrong spot short-cycles or leaves half the room warm. We look at furniture layout, window placement, and doorways before choosing a wall, so the air reaches where you actually sit, sleep, and work.
Tidy Exterior Work
Ductless systems live partly outside your home, where everyone can see them. We keep line runs short, use covers where they help, and set the condenser on a stable stand or pad that suits the property and keeps snow off the coil.
Independent Room Control
Each indoor head responds to its own remote or app, so the nursery can stay cooler than the living room. We set up the controls with you, explaining modes and schedules so every family member understands how to use the system.
Energy Use That Stays Low
Inverter compressors adjust their speed to match the cooling load instead of cycling on and off. Combined with the absence of duct losses, that approach lets you cool specific rooms efficiently without running a whole-house system for one hot bedroom.
Service After the Install
Ductless systems need regular cleaning to keep performing, and not every contractor services what they sell. We offer ongoing maintenance and repair for the mini splits we install, which means one familiar team handles your equipment for years.
Response Any Hour
An office or bedroom that depends on one ductless head can become unbearable when it fails. We answer calls 24/7 and dispatch technicians who carry the diagnostic tools needed to read error codes and restore cooling without unnecessary delays.
Cool the Rooms That Have Always Been a Struggle
Every home has a space that never quite keeps up in July, whether it is a converted attic, a sunny addition, or a basement office. Charest Heating and Cooling solves those problems for homeowners in Berkley, MI and the surrounding area with ductless systems that fit the room and the way you live in it. We plan placement carefully, keep the exterior work neat, and stay available for service long after installation day.
