Ductless Mini Split Installation

What Is a Ductless Mini-Split System?

A ductless mini-split is a heat pump system that provides both heating and cooling without relying on traditional ductwork. Each system includes an outdoor unit connected to one or more indoor air handlers, allowing for independent temperature control in individual rooms or zones.

Ductless mini-splits are ideal for:

Homes without existing ductwork
Additions, basements, garages, and ADUs
Older homes with uneven temperatures
Rooms that never feel comfortable
Supplemental heating and cooling alongside an existing system

Because they eliminate duct losses, mini-splits are often more energy-efficient and cost-effective than traditional HVAC systems.

Heating and Cooling All from One System

A common misconception is that mini-splits are primarily for air conditioning. In reality, modern ductless mini-splits provide reliable heating during Colorado’s cold winters.

Benefits of ductless heat pump systems include:

Year-round heating and cooling
Lower energy bills
Zoned comfort—only condition the spaces you use
Quiet, consistent operation
Improved indoor air quality
Minimal disruption during installation

Cold-climate ductless systems are specifically engineered to perform efficiently even when outdoor temperatures drop well below freezing—making them an excellent solution for South Denver homes.

 Trustindex verifies that the original source of the review is Google. Southwest Heating & Cooling actually CARES. They came out on exceedingly short notice today and quite literally helped save a real estate deal for me.

Mike was spot on with his diagnosis based on a text and pictures, and he made sure Joe arrived with the necessary part in hand and ready to install. Joe got the issue taken care of quickly, and what could have become a major last-minute problem was resolved.

As a Realtor, having vendors who are responsive, knowledgeable and willing to jump in when timing really matters is invaluable. Mike and Joe went above and beyond for me and my clients today, and I could not be more appreciative. Highly recommend Southwest Heating & Cooling.

 Trustindex verifies that the original source of the review is Google. I am selling a condo that the buyers used an inspector from hell.Southwest installed the system two years ago so I asked them to provide an inspection by an authorized technician. The buyers tortured me with stupid questions about various components of the system. I had to pester Joe my Technician and Lisa the office manager with picayune questions and details. They very patiently and professionally helped me every step of the way.

 Trustindex verifies that the original source of the review is Google. They didn’t change my filter which is what I thought was part of the maintenance cost. Now I gotta go buy one and do it myself. Attention to detail lacking.

Southwest Heating & cooling recently installed a new central A/C unit at mother’s home. She is 92 y/o with compromised health.
Mike & Lisa went above and beyond in securing the AC unit  & getting it installed promptly.

They were thorough and timely. They were extremely kind and gentle with Mom.

All communications were clear, concise and timely.

5 stars.  Best of the Best ⭐️⭐️⭐️⭐️⭐️

 Trustindex verifies that the original source of the review is Google. Jonas and Joey did a great job installing a heat pump with backup furnace. The installation took two full days, in part because we didn't already have an air conditioner. Throughout the process, they worked hard without breaks while being extremely courteous. They took the time to answer all my "stupid user" questions, and also answered many questions I didn't think to ask. My basement and garage are cleaner now than before they came.
