Licensed HVAC contractor installing, repairing, and maintaining ductless mini-split systems for Germantown homes
Germantown’s older neighborhoods and its newest bonus rooms share the same problem: no ductwork to carry cooled air where it is actually needed. Since 2014, we at Infinity Heating and Air Conditioning have provided residential ductless AC services across Shelby County, giving homeowners a way to cool a sunroom, garage conversion, or room addition without opening up walls for new duct runs.

Mini-Split Installation: We size and install single-zone and multi-zone ductless systems for rooms that were never connected to central air, running the refrigerant line set through a closet, attic, or exterior wall with minimal disruption to your finished space. Every mini-split installation in Germantown starts with a Manual J load calculation so the equipment matches the room instead of a guess.
Room Addition and Bonus Room Cooling: Sunrooms, converted garages, and finished attic space often sit at the far end of a home’s duct run, if they connect to it at all. A dedicated ductless unit gives that room its own thermostat and steady temperature, without waiting on the rest of the house to catch up.
Multi-Zone Systems for Older Homes: Homes built before central air was standard sometimes have plaster walls or masonry that make traditional ductwork impractical to add. We install multi-zone ductless systems that connect several indoor units to one outdoor condenser, so different rooms run at different temperatures from the same energy-efficient equipment.
Mini-Split Repair: When a ductless unit loses cooling power, short cycles, or the outdoor condenser stops responding, our technicians check the refrigerant charge, the line set, and the electrical connections before recommending a fix. Most mini-split repair calls in Germantown are completed the same day.
Mini-Split Maintenance: The indoor head on a ductless system pulls air directly from the room, so its filter needs attention more often than a standard system’s filter. We handle filter service, coil cleaning, and condensate drain checks as part of every Infinity Plus Plan maintenance visit.
Garage and Workshop Cooling: Garages converted into workshops, home gyms, or home offices rarely have supply and return ducts. We install ductless systems sized for these spaces so they stay usable through Memphis area summers, without running new supply trunks through the main house.
Ductless System Replacement: When an aging mini-split can no longer keep up, we evaluate whether a repair, a like-for-like replacement, or an upgrade to a higher efficiency unit makes the most sense, and we can walk through financing options if the timing is tight.
Germantown and the surrounding Shelby County suburbs grew in waves, from older estate lot neighborhoods near the city center to decades of newer subdivisions further out. Not every square foot of every home was built with a duct run in mind. Sunrooms added after the fact, converted garages, bonus rooms finished over a garage, and older homes that predate central air all share the same gap: no ductwork to carry conditioned air where the homeowner actually needs it.
According to ENERGY STAR, the efficiency program jointly run by the EPA and the U.S. Department of Energy, mini-split heat pumps were designed specifically for this situation. Homes or sections of homes without existing ductwork, additions, and outbuildings where extending a duct run is difficult are among the most common reasons homeowners choose a ductless system over trying to stretch a central one.
The reason comes down to how forced air actually travels. Extending a duct trunk into a room that was never part of the original design means routing sheet metal through finished ceilings or exterior walls, often at the cost of the drywall a homeowner just finished paying for. A ductless system replaces that entire duct run with a single refrigerant line set, runs through a hole a few inches wide, and delivers comparable cooling capacity without the construction mess.
When we evaluate a Germantown home for ductless service, we start by identifying which rooms were never tied into the original system and which ones simply lost airflow as additions changed the house’s layout over the years. That assessment tells us whether a single-zone unit will close the gap or whether a multi-zone system makes more sense for the whole home.

When Anthony Brooks noticed a cooling problem shortly after a new installation, most homeowners would assume the HVAC crew had missed something. Instead, the Infinity team traced the issue back to work the roofers had done on the same project and corrected it without argument.
“The installers (Aspen, Clayton, Cameron, David, Wyatt) were outstanding. They ran a new line when it turned the problem was caused by roofers during March installation. The work was exceptional.”
This is the same troubleshooting standard we bring to every ductless install: tracing a problem to its actual cause before charging for a fix. Read Anthony’s full Google review.
Lawrence Wickham needed a full HVAC replacement covering two separate units, the kind of job that can stretch into a stressful week if communication breaks down along the way.
“Clayton and Caleb and team installed a new HVAC system that we are very pleased with. They worked two days to complete install of 2 complete units.”
Multi-unit jobs like this one are common in Germantown homes that need a dedicated ductless zone alongside a main system, and we keep homeowners informed at every stage the way Clayton and Caleb did here. Read Lawrence’s full Google review.

Whether you need a single-zone unit for a new sunroom or a multi-zone system for a home that never had central air, our team can walk through sizing, equipment, and cost before any work begins. Book online with Infinity Heating and Air Conditioning, check our Germantown service area coverage, or ask about the Infinity Plus Plan to keep a new system covered year round.
If a room runs noticeably warmer or colder than the rest of your home, or if it was added after your original central air system went in, it probably was never connected to your duct run in the first place. We check airflow and duct routing during a service call before recommending a ductless unit.
We start with a Manual J load calculation to size the equipment correctly, mount the indoor head unit, run the refrigerant line set through a small wall penetration, and connect the outdoor condenser. Most single-zone installations are completed in a single day.
Yes. Multi-zone ductless systems connect two or more indoor heads to a single outdoor condenser, which lets us cool a bonus room and a garage conversion, for example, without installing separate outdoor equipment for each space.
We look at the age of the system, the cost of the needed repair, and whether the refrigerant it uses is still widely available. A unit under warranty with a minor issue usually gets repaired, while an aging unit facing a major component failure is often better replaced.
Many Germantown homes have additions, converted garages, or finished attic space that was never tied into the original duct system, and some older homes predate central air entirely. Ductless systems were built for exactly this gap, according to ENERGY STAR guidance on homes without existing ductwork.
