Heat Pumps & Ductless Mini-Splits in Colorado
Efficient heating and cooling for extensions, basements, garages and rooms ducting cannot reach.
The problem
What customers call us about
A converted basement, finished garage, sunroom or home office that the existing ducted system was never designed to condition.
How we handle it
Ductless mini-splits heat and cool a single room or zone without extending ductwork. We survey the space, calculate the load, position the indoor head and outdoor unit sensibly, and run line sets neatly rather than across the front of the property.

What the service includes
- Room-by-room load assessment before sizing
- Single-zone and multi-zone mini-split installation
- Cold-climate heat pump installation and changeover set-up
- Existing mini-split servicing, cleaning and repair
- Tidy line-set routing and condensate management
Who it suits
Basement conversions, garage workshops, additions, sunrooms and older properties without ductwork.
Why choose Cool Flow HVAC
- Heating and cooling from one unit, controlled room by room
- No ductwork to install, so far less disruption to the property
- Lower running costs than electric resistance heating in the same space

Do heat pumps work in Colorado winters?
Cold-climate models are rated to produce useful heat well below freezing. We size for your property's design temperature and discuss back-up heating where it makes sense.
How many indoor units do I need?
It depends on room sizes, layout and how you use the space. We work that out during the survey rather than quoting blind.
