Ductless Air Conditioning in Evansville & Louisville

Mini-splits, or ductless air conditioning, is an increasingly popular type of HVAC system. Like a heat pump, a ductless mini-split has an indoor and outdoor unit that heats and cools. However, ductless ACs directly transfer heat outdoors through a built-in air handler. Because they function independently, without air ducts, mini-splits provide zoned climate control when needed. You can save energy and money by only cooling the offices in use or not air conditioning the kids’ bedrooms while they’re away at college.

A+ Derr Heating and Cooling provides comprehensive mini-split services. We can install new ductless mini-splits and maintain or repair a ductless AC you already have.

Call A+ Derr Heating and Cooling or contact us online to discuss ductless mini-splits for your home or business in Louisville, Evansville, Henderson, Owensboro, or Newburgh!

Ductless Mini-Split Installation & Replacement

If you’re thinking about getting a new AC or replacing an old one for your home or office, consider going with a ductless AC unit. It’s efficient, affordable, and often the perfect solution. For instance, if you have a DIY sunroom and don’t want to pay to extend your ductwork, a ductless AC is ideal. Mini-splits are also fantastic for historic homes where you don’t want to disturb the structure to install air ducts or for new homes without ducts when you’re looking to save money.

Ductless mini-splits are quicker, easier, and less expensive to install than traditional AC systems that need ductwork. Unlike window ACs, they don’t block your views and allow you to open your windows for fresh air when you don’t need heating or cooling. Plus, one outdoor unit can support multiple indoor mini-splits, each with its own thermostat, saving energy and accommodating different temperature preferences.

Since they avoid the common issue of leaky ductwork, mini-splits are more efficient than other ACs. They’re an excellent choice for AC replacement because they’re affordable to install and run, and they can be tailored to fit all your comfort needs.

Ductless Mini-Split Repair

If your ductless air conditioning needs repair, call A+ Derr for a fast, lasting fix. We’re available 24/7, so you never have to choose between leaving and suffering if your mini-split has a breakdown.

Call us for ductless AC repair if you notice:

  • Increased energy bills
  • A broken thermostat or remote control
  • Your AC is struggling to achieve your preferred temperature
  • Your air conditioner continually running
  • Leaks
  • Strange smells or noises

Ductless Mini-Split Maintenance

Schedule ductless mini-split maintenance in the spring and the fall for peak heating and cooling, fewer service calls, and a longer life for your mini-split. A technician will:

  • Clean the pipes, condensing unit, and evaporator coils

  • Clean or replace air filters
  • Inspect the condensate drain
  • Fix minor issues before they grow into significant problems that could cause a breakdown

Jake came and did my spring service yesterday. Their service is very professional, they are always out to get the best deals for anything I may need. I purchased new units from them a couple years ago, and the savings has been so noticeable.
