Flexible Ductless AC Solutions for

Homes and Businesses

Efficient Comfort Without

the Ductwork

Not every space is suited for traditional central air conditioning, and not every project justifies the cost of installing new ductwork. If you're looking to cool a home addition, a garage, a sunroom, a bonus room, or a property that lacks existing duct systems, a ductless mini-split system may be the perfect solution. Star Heat & Air in Hendersonville, TN, specializes in ductless AC installation, repair, and maintenance for residential and commercial customers throughout Sumner, Davidson, and Robertson Counties.

With 40 years of family-owned HVAC experience, we'll help you select and install the right ductless system for your space and budget and keep it running efficiently for years to come.

Homeowners can get up to $800 in rebates in the form of a check simply by installing or replacing their high-efficiency ductless system.

What Is a Ductless Mini-Split System?

A ductless mini-split system is made up of two main components: a compact outdoor condenser unit and one or more indoor air-handling units that mount to the wall or ceiling inside your space. The two units are linked by refrigerant lines that pass through a small hole in the wall — no ductwork required. Most systems can be installed in a single day with minimal disruption to your home or business.

Many ductless models function as both air conditioners and heat pumps, providing efficient heating and cooling from the same unit year-round, making them an excellent choice for Tennessee's varied climate.

Ductless AC Installation

Whether you need to condition a single room or multiple zones throughout a larger property, Star Heat & Air will size and install the right ductless system for your application. We work with reliable, energy-efficient equipment and handle every aspect of the installation, from selecting the optimal placement for both indoor and outdoor units to final testing and commissioning.

Our ductless installation services include:

  • Single-zone systems for individual rooms or spaces
  • Multi-zone systems that connect multiple indoor units to one outdoor condenser
  • Heat pump models for year-round heating and cooling
  • Ceiling cassette and wall-mounted indoor unit options
  • Full electrical work and refrigerant line installation
  • System testing and walkthrough before we leave

A properly sized and installed ductless system will run more efficiently, last longer, and keep your space more comfortable, so we take the time to get it right.

Ductless AC Repair

Like any HVAC equipment, ductless systems can develop issues over time. Our technicians are experienced with all major ductless brands and can diagnose and repair problems quickly to restore your comfort. We service all makes and models.

Common signs your ductless system may need repair:

  • The unit is running but not cooling or heating effectively
  • Ice forming on the indoor or outdoor unit
  • Unusual noises such as rattling, grinding, or squealing
  • Water leaking from the indoor air handler
  • The system cycling on and off repeatedly
  • An unexplained increase in your energy bills
  • Error codes or warning lights on the control panel

Don't ignore early warning signs — catching issues early almost always means a simpler, less expensive repair.

Ductless AC Maintenance

Routine maintenance is essential for keeping your ductless system operating at peak performance and efficiency. Dirty filters, clogged drains, and neglected coils force the system to work harder, reducing comfort, raising energy costs, and shortening the system's lifespan.

Star Heat & Air offers professional ductless maintenance services to keep your equipment in top condition season after season. A standard maintenance visit includes:

  • Cleaning or replacing air filters in all indoor units
  • Inspecting and cleaning evaporator and condenser coils
  • Checking and clearing condensate drain lines
  • Inspecting refrigerant levels and checking for leaks
  • Testing electrical connections and system controls
  • Evaluating overall system performance and efficiency

We recommend scheduling maintenance at least once per year, ideally before the start of the cooling or heating season. Ask us about our maintenance plans for ongoing coverage and priority scheduling.

Is a Ductless System Right for Your Space?

Ductless mini-splits are an excellent solution for a wide range of applications:

  • Home additions, sunrooms, bonus rooms, or converted garages
  • Older homes built without a central duct system
  • Rooms that are consistently too hot or too cold even with central HVAC
  • Rental properties or detached structures such as workshops or in-law suites
  • New construction where duct installation isn't practical
  • Commercial spaces requiring independent zone control
  • Any space where running ductwork would be too costly or disruptive

Not sure if a ductless system is the right fit? Our technicians are happy to evaluate your space and walk you through your options at no obligation.
