Ductless HVAC Systems: The Reliable Heating & Cooling Choice in University City, MO

A ductless HVAC system provides an energy-efficient solution for homeowners and businesses looking to optimize their cooling and heating options. As the name suggests, they do not rely on traditional ducts to distribute warm or cool air throughout the home or business, making them an attractive option for both new constructions and older buildings. They are capable of providing targeted comfort within specific zones in your home or workplace, ensuring both efficacy and cost-efficiency.

Understanding Ductless Mini Split Systems

The concept behind a ductless mini-split system is quite straightforward. Unlike a traditional central HVAC system that uses a network of ducts, a mini-split heating and cooling unit functions independently. It consists of two main components: an outdoor compressor/condenser and an indoor air-handling unit, connected by a conduit. This simple yet effective system provides both heating and cooling services, working around the clock to keep the temperature in your spaces just how you like them.

Since its inception in 1972 by Ken and Marilyn Patterson, Reliable Heating & Cooling has been at the forefront of providing quality installation and service work in the residential and light commercial marketplace. The company incorporated in 1980 and has since consistently provided expert ductless mini-split installations in University City, MO.

Ductless Split Installation: A Reliable Solution

Opting for a ductless split installation offers a host of unique advantages. For starters, it allows for greater energy efficiency as heat loss typically associated with ductwork does not occur. Further, installation is less invasive and more flexible, with the indoor units able to be mounted in various locations, including on walls or in ceilings. This makes them particularly suited for older homes or buildings with strict architectural restrictions.

At Reliable Heating & Cooling Co., our credo has always been to create a comfortable and healthy living space for our clients.

Customer Reviews
What our customers are saying

Reliable has installed and maintained our last 2 furnaces and AC. Our experience with them has been great. Just yesterday we had an issue with our AC. I talked to Marty and he said he’d have someone out the next day. They even were able to accommodate us with an afternoon call. Derrick arrived promptly on time and had us up and going again in 15 minutes (bad capacitor on the condenser unit fan motor). With the prediction of high 90 temps, we were so thankful to have AC working again.

Keith Scherer

I had a system malfunction on Sunday evening December 12, 2022 on my Carrier Infinity ICS purchased in 2008.I am a first time caller to Reliable. Marty called me back and had his Tech dispatched at 8 AM the next day. The unit had failed and was dangerous to use. He had a new system by the next morning. They installed it and I was completely satisfied with their service and response time. I overwhelmingly recommend Reliable and will be using them from now on.


We had a emergency water leak problem with our AC unit in the basement of our recently purchased condo. Called Reliable and Derrick was there within a couple of hours. He was polite, knowledgeable, and friendly. Derrick quickly found the problem and repaired it. He also checked the system overall, pointed our some concerns and answered all my questions. I can’t say enough about how satisfied we were with Derrick and Reliable Heating & Cooling! We would definitely recommend them!!! Thanks again!!!!

Terry Mills

Have been with them for more than 10 years. They provide exceptional service…from the time they call to remind you about setting an appointment to the actual service day. Derek (and all their other technicians) are knowledgeable, professional, prompt, and open to listening to questions and pay attention to details. Never had a problem with anything. Thank you for a job well done. Good pricing.

Seema Chouhan

Had a small gas leak for a property I was helping a friend sell and we found out late last night. We reached out to Reliable H&C and Derrick was over first thing in the morning. He was friendly, professional and knowledgeable. He answered my questions with a smile. Derrick was a rock star. Will absolutely call him again. Bravo

Connor Kapp

We have used Reliable Heating and cooling for all of our heating and cooling needs. We needed some water heater work and Ralph came out and took care of it right away. Ralph was very professional and knowledgeable. He got the job done very quickly and everything is working great! I always recommend Reliable to family and friends. They truly are Reliable!
