Is a Ductless HVAC System Right for Your Home or Office?

If you’re considering solutions to better heat or cool a room or small area of your home or office, a ductless mini-split HVAC unit from Carrier can be a very efficient solution. Don’t confuse them with the old window units of yesteryear that were loud, dusty, and sucked down electricity like a sieve. Sleek new mini-split systems consist of a smaller outdoor condensing unit and a little indoor air handler which we call a head. The indoor unit is generally mounted high up on the wall (though other shapes/sizes are available). They are generally a highly efficient heat pump that generates warm air in the cooler months and cool air when it is blazing hot. You can get them with heat and air conditioning or just air conditioning only. Most models come with a remote control, too.

Ductless systems are infinitely flexible because they don’t have ducts to install. They are installed with a small hole on the outside wall to connect the indoor and outdoor unit and can be installed in a day or less in most situations. They are best used to efficiently heat or cool the following:

  • new additions,
  • upstairs rooms,
  • master suites,
  • children’s playrooms,
  • man caves,
  • sewing or craft rooms,
  • home offices,
  • employer conference rooms,
  • theater rooms,
  • guest rooms,
  • attic rooms,
  • garages, and
  • more.

If you have an older home with no space for ducts, they work very well and can help you avoid major construction. You can use them to help with creating comfort zones in your home so you can run your main thermostat a little lower. You can install them in rooms that are used more often and power down your home’s central air and heat so you are only using the air and heat that you need. We have also installed them in garages so that families can reclaim that space and be more comfortable. In the office, if you have co-workers bringing in contraband space heaters to stay warm, a ductless system in that one area might fix the comfort problem permanently.

Should a ductless system be used throughout a home or office?

In most cases, the answer is no. While you can link multiple ductless air handlers to one outside mini-split condensing unit, most situations we see involve just one or two ductless systems to address climate control in a specific area or room. Ductless systems are powered with electricity and are ultra efficient with this application. Depending on how large your home or office is, it is usually more cost effective to have a standard central air and heating HVAC unit to heat or cool an entire home or office. We would need an onsite review to give you the best advice about what might work best for your situation. In the Houston, Texas and Gulf Coast area, we generally have a milder climate so the amount of cooling and heat these units produce work very well for our hot, humid summers and cool winters.

What other advantages do ductless HVAC systems have?

Ductless systems are ultra energy efficient and all the models that Carrier makes are ENERGY STAR® qualified which makes them inexpensive to run year round. They are also very quiet and help maximize room space, since the indoor head hangs on the wall close to the ceiling. With proper maintenance, they can last 15-25 years which is a great investment. The only regular maintenance task is cleaning out the filters monthly, which can be run through a standard dishwasher.
