Looking for a more efficient way to heat or cool your home without the hassle of ductwork? A ductless mini split could be the solution. These systems offer precise temperature control for individual rooms, are quick to install, and require no major remodeling or construction. Whether you're upgrading an older home, finishing a garage, or adding comfort to a room that never stays quite right, ductless systems deliver flexibility and energy savings.
Our team of HVAC professionals is experienced in installing, repairing, and maintaining ductless mini split systems of all types. If you’re considering a ductless option, we’re here to help you find the perfect fit.
How Do Ductless Mini Splits Work?
Unlike traditional HVAC systems that rely on a network of air ducts, ductless mini splits consist of two primary components: an outdoor compressor/condenser unit and one or more indoor air-handling units. These components are connected by a small conduit that houses the refrigerant line, power cable, and drainage tubing.
During operation, the system uses refrigerant to transfer heat. In heating mode, heat is drawn from outside and moved into the home. In cooling mode, the process reverses, removing heat from the indoor air and releasing it outside. Because this is a closed-loop system and no ductwork is involved, energy loss is minimal, making it a highly efficient way to control indoor temperature.
Benefits of a Ductless Heat Pump
While ductless air conditioning systems are available for those solely looking for a cooling solution, we frequently recommend ductless heat pumps to our customers because they provide both heat and air conditioning.
Today’s ductless mini-split systems boast a huge amount of heating and cooling capacity in a small, easy-to-maintain package. Installation is easy (usually all you need is one small hole cut in your wall), and you only need one outdoor compressor to support multiple units.
Here are some of the benefits ductless heat pumps provide:
- Individual control: You can set the temperature in each room, so no more arguing over the thermostat!
- Only use what you need: Since you can turn off the air in rooms you’re not using, you’ll use only a tiny fraction of the energy you would use with a standard central AC system.
- Customizable: Ductless heat pumps can be installed in almost any room in your home, including attics, garages, and more.
- Low maintenance: Annual ductless heating maintenance is all you need to keep your heating and cooling system in great shape.
- Affordable: Installing ductless HVAC units in your home usually costs about the same or less as installing new central air conditioning.
We offer a number of ductless split system models to suit every household and budget. Whatever your goals are for your HVAC system, our team can assist you in finding the best option for your home.

Ductless Mini Split Maintenance
Preventive maintenance is key to keeping your ductless mini split efficient and reliable. Regular service helps improve performance, reduce energy costs, and extend the system’s lifespan.
Our maintenance visits include:
- Cleaning filters and indoor coils
- Checking refrigerant levels and system pressure
- Inspecting electrical connections and safety controls
- Flushing the drain line and confirming proper condensate flow
- Verifying that your unit responds accurately to the thermostat or remote
We recommend scheduling service once a year, ideally before the heating or cooling season begins.
Neglecting regular maintenance can lead to reduced system efficiency, premature wear, and unexpected breakdowns, especially during the peak of winter or summer.
