Mini Split Installation: Efficient Heating & Cooling Without Ductwork.
Not every home has ductwork. Not every room receives enough heating or cooling from the central system. Not every addition, garage conversion, or basement finish can tie into the existing HVAC system. And not every homeowner wants to tear open walls and ceilings to install new ductwork.
That's exactly what mini split systems were designed to solve.
A ductless mini split delivers precise heating and cooling exactly where you need it, without ductwork, without major renovation, and with efficiency that often surpasses traditional central systems.
Power Electrical, Heating & Cooling Services installs mini split systems for homeowners across the Denver metro area, including single-zone and multi-zone systems, new installations, and full replacements, all professionally installed and fully code compliant.
What Is a Mini Split System?
The Basics: Explained Simply
A ductless mini split system consists of two primary components: an outdoor condenser unit and one or more indoor air handlers mounted on the wall or ceiling of the spaces you want to condition.
The two components connect through a small conduit running through approximately a three-inch wall opening, carrying refrigerant lines, electrical wiring, and a condensate drain line.
There are no ducts. No major construction. No tearing open walls to run ductwork throughout your home.
The indoor air handler delivers heated or cooled air directly into the space, quietly, efficiently, and with precise temperature control using a dedicated remote or smart thermostat.
Each zone operates independently, allowing you to heat one room while cooling another, or simply turn off unused zones completely.
Mini splits are heat pumps, meaning they move heat rather than generate it.
In cooling mode, they remove heat from inside your home and move it outdoors. In heating mode, they reverse the process, extracting heat energy from outdoor air and moving it indoors.
This technology makes mini splits dramatically more efficient than electric resistance heating and effective across a much wider temperature range than most homeowners expect.

Is a Mini Split Right for Your Home?
These Are the Most Common Mini Split Applications We Install in Denver Metro
Many Denver metro homes built before the 1970s were constructed without central air conditioning and have no existing ductwork for cooling.
Adding traditional ductwork to these homes is expensive, invasive, and often impractical.
A mini split delivers targeted or whole-home comfort without tearing open walls to install ductwork.
When adding a room, sunroom, enclosed porch, or addition, tying into your existing HVAC system is often impractical because the original system was not sized for the additional load.
A mini split serves the addition independently, delivering the right amount of heating and cooling without straining the existing HVAC system.
One of the most popular mini split applications in the Denver metro area.
Whether you're converting a garage into living space, building a workshop, or simply making your garage comfortable year-round, a mini split is often the most practical and efficient solution.
No existing ductwork required. One dedicated electrical circuit powers the system.
Finished basements in Colorado commonly struggle with central HVAC balancing issues, too cold in winter and too warm in summer.
A mini split provides independent temperature control without fighting against the rest of the home's HVAC system.
If one room is always too hot or too cold regardless of thermostat settings, a mini split is often the simplest and most affordable solution.
Instead of rebalancing the entire HVAC system, you create dedicated comfort exactly where it's needed.
Mini splits are increasingly used in new additions, ADUs, accessory structures, and projects designed without traditional ductwork from the start.
Builders and architects frequently specify mini splits because of their flexibility, efficiency, and simplified installation.

Joey came out and did a fantastic job looking over and cleaning my system for the winter. I had someone come out earlier in the year, but it felt more like he was trying to get me to buy a new system than help with my existing. Joey looked over the system, gave a few small but very helpful suggestions, and cleaned it. Could not recommend these folks enough.

I had purchased an oven and needed an outlet swap as soon as possible. Lance came out right at the beginning of the service window, was very thorough during the estimate procedure and was extremely knowledgeable and answered a lot of questions I had about my circumstance. Couldn't be happier with the communication and service performed. I will definitely utilize this company again in the future.

Just moved into our new (2000 build) house and Joey came out to do winter maintenance on our furnace. This company was recommended from the former owner. Joey was professional, polite and very helpful - showing me how to change the furnace filter and the humidifier pad. He cleaned out the furnace, inspected the system, (which is newer) and told me everything was in good shape – didn’t try to sell me anything extra. I like them and will use them again.

The Mini Split Installation Services Professionals
Mini splits are among the most energy-efficient heating and cooling systems available.
Traditional electric resistance heating systems convert one unit of electricity into one unit of heat.
Mini split heat pumps move three to four units of heat for every unit of electricity consumed, making them dramatically more efficient by comparison.
For garages, additions, and older homes currently relying on electric baseboard heating, portable heaters, or window AC units, the efficiency difference can significantly reduce utility costs.
Federal tax credits and Xcel Energy rebates make the investment even more attractive financially.

Get comfort exactly where you need it.
1. What is a mini split system and how does it work?
A mini split, also called a ductless mini split or ductless heat pump, is a heating and cooling system consisting of an outdoor condenser connected to one or more indoor air handlers.
Unlike traditional HVAC systems, mini splits deliver conditioned air directly into the room instead of through ductwork.
Mini splits operate as heat pumps, moving heat rather than generating it, making them extremely energy efficient.
2. What is the difference between a single-zone and multi-zone mini split?
A single-zone system serves one room or space using one indoor air handler.
A multi-zone system uses multiple indoor air handlers connected to one outdoor condenser, allowing independent comfort control across multiple rooms.
The right configuration depends on how many spaces you need to condition and how you use your home.
3. Do mini splits work well in Colorado winters?
Yes.
Modern mini split systems are designed to operate efficiently in outdoor temperatures well below zero degrees Fahrenheit.
Denver metro winter temperatures fall within the operating range of properly selected mini split equipment.
The key is installing cold-climate-rated systems designed specifically for low outdoor temperatures.
4. What size mini split do I need for my room or garage?
Mini split sizing depends on square footage, insulation, ceiling height, windows, and sun exposure.
As a general guideline, a 12,000 BTU system commonly handles spaces around 400 to 600 square feet, but every installation requires proper load calculations.
Oversized systems short cycle. Undersized systems struggle to keep up.
We size every system properly based on the actual space.
5. Do mini splits require a dedicated electrical circuit?
Yes.
Most mini split systems require a dedicated 240V electrical circuit sized specifically for the equipment.
One advantage of working with Power Electrical, Heating & Cooling Services is that we handle both the HVAC installation and the electrical work during the same visit.
No separate electrician required.
6. Can a mini split heat and cool different rooms at the same time?
Yes, multi-zone systems can.
Each indoor air handler operates independently, allowing different rooms to maintain different comfort settings simultaneously.
This flexibility is one of the biggest advantages of ductless systems.
7. Are mini splits worth it in Colorado?
For many homes and applications, absolutely.
Colorado's climate, rising energy costs, home addition trends, and older housing stock make mini splits one of the most practical and efficient comfort solutions available.
For garages, additions, basements, and homes without ductwork, mini splits are often the best solution available at any price point.
