Ductless Mini-Split Services in Cincinnati & Blue Ash, OH

Ductless mini split system mounted on a yellow wallA ductless mini-split eliminates the need to install ducts throughout your home, as is traditional with central heating and air conditioning systems. With a mini-split, the unit is installed outside and connected to an inside unit through wires. The inside unit then blows the air into the room, making it comfortable with maximum precision.

As you look for a way to make your home more comfortable throughout a Cincinnati summer, consider installing a ductless AC system.

National Heating and Air Conditioning’s experienced and certified HVAC team can help install a new ductless mini-split system, repair an existing system, and provide maintenance services for your mini-split system!

Ductless Mini-Split Installation & Replacement

Temperatures in the Cincinnati area can be extreme. You may already have a heating system but would like to add air conditioning to your home without installing ducts. Some homes cannot handle a duct system for one reason or another.

By installing a ductless mini-split, you can enjoy air conditioning without putting in a lot of work or relying on unsightly window units. The mini-split is adaptable and allows you to focus on one or several rooms from one outdoor unit.

Consider installing a ductless mini-split in one of the following areas of your home:

  • Finished basements
  • Guest houses
  • Pool houses
  • Garages
  • Workshops
  • Sunrooms
  • Home additions

Benefits of a New Ductless Air Conditioner

Eliminating the need for ducts isn’t the only benefit of opting for a ductless mini-split. Here are several more to help you in making your new ductless AC replacement or installation decision.

  • Enhanced Flexibility: Whether it’s one room or several, the mini-split allows you to determine where you need more heating or cooling. Concentrating on only the required areas is reflected in lower energy bills.
  • Quick installation: Without the need to install new ductwork in your home, ductless mini-splits are quick to install, so they are up and running in no time.
  • Personalized comfort: Ductless mini-splits allow for zoned temperature control, providing personalized comfort in any room where one is installed.
  • Improved energy efficiency: You can turn mini-splits on and off since they are specific to a particular area of your home. Because of this, these systems are not constantly running and cooling unoccupied rooms. This also helps to reduce your utility bills.
  • Better indoor air quality: Since there’s no ductwork with these systems, there is nowhere for dirt and dust to collect and be redistributed into your home. Ductless mini-splits also have better filtration and act as dehumidifiers.

Benefits of Ductless HVAC Maintenance

Scheduling ductless HVAC maintenance provides much more than some cleaning and parts checks. When you keep up with maintenance, you earn many substantial benefits, including:

  • Higher heating and cooling performance: When your system is appropriately calibrated and cared for, you can expect more comfort, power, even temperatures, and effective humidity control.
  • Reduced energy costs: A properly functioning ductless system boasts maximum energy efficiency, helping to reduce your energy bills throughout the season.
  • A lower risk of breakdowns: More than half of the ductless HVAC repairs our teams perform are caused by a lack of maintenance. Taking care of your system means fewer repair bills and substantially lower upkeep costs overall.
  • Better indoor air quality: The cleaning component of a professional maintenance service clears out gunk and dust that can clog up your indoor units, freeing them and your home from air pollutants.
  • Longer equipment lifespans: Ductless systems can last for years — up to 10 or even 15 if you ensure the system is maintained frequently.

Ductless Mini-Split FAQs

Ductless systems have become exceedingly energy-efficient in recent years. The average air conditioner loses a quarter of its energy through its ductwork. If you have leaky ducts, you can push that number up to 30%, so you’ll find your mini-split electricity bills pleasantly low. One ductless unit with a BTU of 36,000 can cool 1,500 square feet of space at a SEER rating of 20 or more.

SEER stands for “seasonal energy efficiency ratio (or rating)” and is an efficiency rating for your heating or cooling system. A SEER of 14 or higher is considered a good rating. A higher SEER system allows the system to run more efficiently, providing your home with better comfort for a lower cost.

You do not need to outfit every room with a mini-split. Most homes get by with one outdoor unit in the primary living areas. They can attach to several indoor mounts covering three rooms at a time. If you want perfect zone control, a multi-split AC will provide it. Your installation team will assess your household layout and shared walls before arriving at the ideal setup for your ductless units.

Your mini-split filter is easy to clean with a little warm water and a vacuum cleaner. To enjoy unrestricted airflow, you’ll need to keep your system free of clutter with routine wiping with a damp cloth. You can leave the rest of your annual service duties to the professionals. Your technician will inspect each part, address excess moisture, and ensure unimpeded drainage. Fortunately, you don’t need to worry about ductwork maintenance or cleaning, so your maintenance bills will be impressively low.

Each type of home comfort system you have requires one maintenance service per season. This goes for heating, cooling, and air quality systems. If your ductless split system is AC only, one service a year is sufficient. If you have a ductless heat pump that provides heating and cooling, you’ll need the unit serviced twice a year — ideally once before summer and once in the fall.

What Our Clients Are Saying

Brandon of National Heating did an excellent job servicing my AC. He is very thorough, knowledgeable, and professional. He discovered that the low outside temperature sensor had not been set up on my Evolution Connex Control and took care of it. I appreciated his top-notch service!

Thomas S.

Great company that I trust. Very thorough. I just had my air conditioner annual service. I used Help in the past. They always tried to upsell every opportunity they had. National Heating and A/C is the real deal from booking the appointment to the actual work. Every person I have dealt with is kind, knowledgeable, and…

Paul M.

I can highly recommend National (previously Nelson Comfort) Heating and Air especially if Sanjay is the company representative. He was beyond good in that he completely cleaned the outside unit and was very thorough with the ac equipment inside the house. He even destroyed a wasp nest that I had not noticed. Five stars for this…

Susan S.

Excellent experience all around. Communication from the company was timely and complete. My service technician Chad Wilson was very knowledgeable, efficient and helpful. I had a lot of questions, having just moved into a house with systems that were unfamiliar to me (geothermal, radiant heat). Chad answered all my questions and spent extra time helping me…

Mary C.

My family has been using this company for years. They've always provided us with honest feedback on pricing for repairs and maintenance. This means a lot to a family on a tight budget. We never feel like we are charged for unnecessary items. All charges are explained and examined in great detail before being followed through.…
