A room addition, converted garage, or older home without existing ductwork does not need a full duct system just to get cooled properly. Infinity Heating and Air Conditioning installs, repairs, and maintains ductless mini-split systems for homeowners throughout Collierville, giving individual rooms or additions their own cooling and heating without cutting new ducts through finished walls or ceilings.

We at Infinity Heating and Air Conditioning are licensed in the State of Tennessee and have installed and serviced ductless systems for Collierville homeowners for more than a decade. Every job starts with an on-site look at the space, not a quote based on square footage alone.
We work on ductless mini-split systems at every stage, including:
We start with an on-site visit to look at the specific room or addition, not just its square footage, since ceiling height, insulation, sun exposure, and window area all affect what capacity the space actually needs. From there, we recommend a single-zone or multi-zone configuration depending on how many rooms need coverage and whether they can share one outdoor unit. On installation day, our technicians mount the indoor unit, run the line set and drain to the outdoor condenser, and seal the wall penetration to keep the space weathertight. Where the job involves more than one indoor unit, we plan the line set routing and outdoor unit placement together before any mounting begins, so the finished installation looks intentional rather than improvised. We test the system for proper refrigerant charge and airflow before walking the homeowner through the remote or thermostat controls, and we clean up the work area fully before we consider the job done.

Collierville sits within Shelby County, a market with more than 400,000 housing units spanning a wide range of construction eras and price points, according to the U.S. Census Bureau’s American Community Survey. That range of construction eras is exactly why ductless systems come up so often in Collierville: a house built decades ago with a room addition tacked on afterward, or a garage converted into a home office or workout space, frequently has no ductwork running to that specific area at all.
Extending a central system’s ductwork into a space that was never designed for it usually means cutting into finished walls or ceilings, rerouting supply and return runs, and living with the disruption of that work inside an occupied home. A ductless mini-split solves the same comfort problem with a line set about as thick as a garden hose, run through a small wall penetration instead of a full duct run. That makes ductless the more practical option for additions, garages, sunrooms, and older homes in Collierville where the existing duct system was never built to reach the new space, and it is why we recommend it as often as we do for jobs exactly like these.
There is also an efficiency argument specific to this situation. A central system fighting to push conditioned air through a long new duct run tacked onto an existing system loses some of that capacity to the added distance and any leaks in the new ductwork. A ductless unit delivers air directly into the room it serves, with no duct run to lose efficiency along the way, which matters most in exactly the kind of retrofit and addition work that makes up a large share of our ductless calls in Collierville.
Every ductless job is priced after we see the space, but the variables that typically move the estimate include:
We walk through each of these during the on-site visit so the written estimate reflects your specific room, not a generic ductless price pulled from an average job.

Ductless systems are a strong fit for room additions, converted garages, sunrooms, and older homes where existing ductwork does not reach the space that needs cooling. They are also useful where extending traditional ductwork would mean cutting into finished walls or ceilings. An on-site visit is the best way to confirm whether ductless or a central system extension makes more sense for your specific room.
Yes. Modern ductless mini-splits are built to handle sustained summer heat and provide both cooling and, on heat pump models, heating for the space they serve. Capacity is selected based on the room’s size, insulation, and sun exposure during the on-site visit, not a generic sizing chart. A correctly sized unit keeps the space comfortable through the hottest stretches of the cooling season.
Cost depends on whether the job is a single-zone or multi-zone system, the capacity needed for the space, and how far the indoor and outdoor units sit from each other. We provide a written estimate after seeing the specific room or rooms involved, since a generic price would not reflect what your installation actually requires. Financing is available for qualifying installations.
Yes, this is one of the most common reasons Collierville homeowners contact us about ductless systems. A garage converted into livable space or a room addition built after the original ductwork was installed often has no practical way to tie into the existing duct system. A ductless unit gives that specific space its own cooling and heating without requiring changes to the rest of the home’s ductwork.
Most single-zone ductless installations in Collierville are completed in one day, including mounting the indoor unit, running the line set to the outdoor condenser, and testing the system. Multi-zone systems covering several rooms can take longer depending on how many indoor units are involved. We will give you a specific timeline as part of the written estimate.
Yes. Ductless systems benefit from periodic coil cleaning and refrigerant checks to keep them running at their rated efficiency, similar to a central system. Skipping maintenance can lead to reduced cooling performance and higher energy use over time. We offer routine maintenance service for ductless systems as part of our regular HVAC maintenance offerings.
