Ductless mini-splits solve the problems central systems cannot: a converted garage, a bonus room over the garage, an addition with no duct run, or a house where one end is always ten degrees off. Air 911 Heating and Cooling LLC covers both mini-split repair and maintenance and mini-split installation.
Mini-splits are not simplified air conditioners. They run inverter-driven variable-speed compressors, communicating controls and, in multi-zone configurations, branch distribution that has to be diagnosed as a system rather than a single unit. That sophistication is exactly why they are efficient, and why they need technicians who understand them.
We install Samsung mini-split systems, including Wind-Free models, and service other ductless brands. Our technicians are NATE certified and licensed in Tennessee, Alabama and South Carolina.

Error Codes, Weak Output, Odors
Ductless equipment lives or dies on indoor unit cleanliness. Blower wheels and evaporator coils collect biofilm in our humidity, and that shows up as reduced output and musty air long before it shows up as a fault code. We deep clean both, and diagnose inverter and communication faults.
Mini-Split Repair & MaintenanceSingle Zone & Multi-Zone Systems
Line set routing, condensate drainage, indoor head placement and zone sizing all get planned before the first hole is drilled. A mini-split that is placed well disappears into the room; one that is not becomes something you notice every day.
Mini-Split InstallationNot sure where to start? Here is how we would think about it.
The efficiency advantage of a mini-split comes from how it modulates, not from the fact that it has no ducts. Understanding that explains both the savings and the service needs.

If you need reliable heating, cooling, or indoor air quality services, we’re your trusted local experts.
A mini-split pairs an outdoor compressor with one or more indoor units mounted directly in the rooms they serve, so there is no ductwork. Each indoor head has its own temperature control, which means you condition the rooms you are using rather than the whole house.
Yes. Mini-splits are heat pumps, so they reverse to provide heating as well as cooling. That makes them a practical year-round solution for additions, converted spaces and rooms that a central system never served well.
At least once a year, and the priority is the indoor unit. Blower wheels and evaporator coils collect buildup in Chattanooga's humidity, which reduces output and causes musty odors. Professional deep cleaning of the indoor unit is the core of ductless maintenance.
We install Samsung mini-split systems, including Wind-Free models with smart features and multi-zone options. We also service other major ductless brands.
If you have been closing a door on a room because it is unusable half the year, ductless is worth a conversation. Air 911 Heating and Cooling LLC will look at the space, tell you what a mini-split would and would not fix, and quote it honestly.
