Add Heating and Cooling Without Ductwork

Alteam HVAC installs and services ductless mini split systems for homes in Detroit that need targeted climate control without existing ducts.

If you live in Detroit and have a room addition, a finished garage, or an older home that was never built with ductwork, a ductless mini split system gives you heating and cooling in specific areas without tearing into walls or ceilings. These systems use a small outdoor compressor connected to one or more indoor air handlers mounted on the wall, and each unit can be controlled independently to match the temperature needs of that space. You get year-round comfort in rooms that were previously too hot in summer or too cold in winter.

Alteam HVAC installs ductless mini split systems throughout Detroit and provides ongoing repair and maintenance support to keep your units running efficiently. The systems are energy-efficient because they only heat or cool the rooms you are using, and they operate quietly compared to window units or portable heaters. Installation involves mounting the indoor unit, running a small refrigerant line through an exterior wall, and connecting it to the outdoor compressor. The process is less invasive than adding ductwork and can usually be completed in a single day.

Call Alteam HVAC in Detroit to schedule a consultation and find out whether a ductless system is the right fit for your home.

How Ductless Systems Work in Real Homes

When Alteam HVAC installs a mini split system in your Detroit home, the technician mounts the indoor unit on an interior wall in the room you want to condition, drills a small penetration through the exterior wall, and runs the refrigerant line to the outdoor compressor. The system is charged, tested, and programmed so you can control temperature and fan speed with a remote or wall-mounted control. Each indoor unit operates independently, which means you can heat the bedroom at night without heating the entire house.

After installation, you will notice immediate temperature control in the treated space, quieter operation compared to older heating methods, and lower energy bills because the system only runs where and when you need it. The air handler also includes a filter that reduces dust and improves air quality in the room.

The service does not include electrical panel upgrades or drywall repair beyond the small penetration required for the refrigerant line, but the technician will confirm your home has the electrical capacity to support the system before starting. Ductless systems are flexible, efficient, and ideal for spaces that do not connect to your main HVAC system.

A lot of people wonder how these actually work

Homeowners in Detroit who are considering ductless mini splits usually want to know how they compare to central air, how much they cost to run, and whether they can heat as well as they cool.

What rooms are best for ductless systems?
Ductless systems work well in room additions, finished basements, garages, sunrooms, and older homes without existing ductwork. They are also a good fit for spaces that are difficult to heat or cool with your main HVAC system.
How efficient are mini split systems?
Mini splits are highly efficient because they use inverter technology to adjust compressor speed based on demand, and they only condition the rooms you are using. This typically results in lower energy costs compared to heating or cooling your entire home.
Can a mini split heat my home in winter?
Yes, ductless mini splits provide both heating and cooling, and they work efficiently in cold weather down to temperatures well below freezing. Alteam HVAC installs units that are designed to handle Michigan winters.
How loud are ductless systems?
Indoor units operate very quietly, usually around the noise level of a refrigerator. The outdoor compressor is also quieter than traditional central air condensers.
What kind of maintenance do they need?
You should clean or replace the air filter in the indoor unit every few weeks, and schedule annual maintenance with Alteam HVAC to inspect refrigerant levels, clean the coils, and test system performance.
