Benefits Of Owning A Ductless Mini-Split

Ductless mini-split systems offer an efficient and flexible way to heat and cool your home. They provide year-round comfort while giving you greater control over individual spaces and reducing energy waste associated with traditional ducted systems.

  • Year-Round Heating & Cooling. A single mini-split system provides both heating and cooling, keeping your home comfortable throughout every season.

  • Improved Energy Efficiency. Ductless systems eliminate energy loss through ductwork and use inverter technology to adjust output based on your comfort needs.

  • Individual Room Control. Set different temperatures in separate rooms or zones, allowing each area of your home to stay comfortable without conditioning unused spaces.

  • Ideal For Homes Without Ductwork. Mini-splits are an excellent solution for older homes, room additions, garages, finished basements, sunrooms, and other spaces where installing ductwork isn’t practical.

  • Quiet Operation. Indoor air handlers and outdoor units are designed to operate quietly, helping maintain a more comfortable living environment.

  • Improved Indoor Air Quality. Built-in filtration helps reduce dust and other airborne particles while providing consistent airflow and improved air quality throughout the conditioned space.

The Ductless Mini-Split Installation Process

Installing a ductless mini-split system requires careful planning to ensure reliable heating and cooling, efficient performance, and long-term system reliability. At Harris Plumbing, Heating, Air, & Electric, our technicians complete every installation according to manufacturer specifications and verify your new system is operating properly before the job is finished.

1. In-Home Evaluation & System Selection

Every installation begins with an evaluation of your home’s layout, comfort needs, and the spaces you want to heat and cool. Our technicians recommend the appropriate mini-split system, determine the ideal indoor and outdoor unit locations, and properly size the equipment for efficient performance.

2. Professional Mini-Split Installation

Once the installation plan is finalized, we securely mount the indoor air handler, install the outdoor unit, connect the refrigerant lines, electrical wiring, and condensate drain, and complete all required system connections. Every component is installed with attention to proper placement, appearance, and long-term reliability.

3. System Startup & Performance Testing

After installation is complete, we charge and test the system, verify refrigerant pressures, confirm proper airflow, and ensure the unit operates correctly in both heating and cooling modes. Before leaving, we show you how to operate your new mini-split system, adjust temperature settings, and understand its key features so you can enjoy dependable comfort from day one.

Had Harris out to do an assessment on my heater and the technician Chris found a dangerous situation with my heater exchanger that could have slowly put carbon monoxide into my house. I’m grateful that Lee was able to come to the house right away and provide me selections and options. I was able to get a new HVAC system the next day and my family can safely sleep in our home. Everyone from Mathew and Chris M to Lee and the install guys, Louis, Mike and Jhar were amazing and genuinely great people I would have in my home any time.

I was quite satisfied with meeting with Josh, yesterday. While I didn't care for the price, I had to expect things would be that high of a cost. Still, Josh's professional conduct while he was inspecting my tank made it that much easier to say, "yes," and go ahead with the installation request. I am not concerned, at this point, about the job itself. The heater installation, earlier this year was very nicely done and the unit is working great.

The technician first of all was polite, he put his booties on. And I appreciate that because I have hardwood floors original. The technician looked at the situation was able to fix the issue and showed me what can be another possible problem if not addressed.

Requested same day service in the AM and Scott was at the house by 3:00. He was very knowledgeable and professional, making sure that he understood what I wanted regarding the outdoor outlet and the line to it. He worked quickly and left the patio cleaner than when he arrived. I would highly recommend Harris for electrical work.
