Ductless Heating and Cooling Systems

A ductless split heating and cooling system gives you the freedom to control the temperature on a room-by-room basis.

For homes with no ductwork (using window air conditioners or no air conditioning), ductless splits (also known as mini-splits) offer a QUIET, energy-efficient alternative.

Imagine the potential energy savings when you can choose not to heat or cool unused rooms, such as guest bedrooms, while at the same time keeping bedrooms or the living room at the perfect temperature for comfort. A ductless split system is also a great option if you have a converted attic, new addition or finished basement.

These high-efficiency systems can also help you save money by helping to keep your most-used rooms optimally comfortable, so that even if you have ductwork, you can potentially spend less on heating and cooling costs for the rest of your home.

We are proud to offer the Lennox and Mitsubishi Electric wall-mounted ductless split systems, both of which are among the highest quality, most energy-efficient ductless split systems available. At Thornton & Grooms, we can help you pick the right system for your needs.

                     Benefits of a Ductless Split System

• Comfort without Compromise. Keep the rooms you use most at precise temperatures for comfort. Keep the kitchen a little cooler than the rest of the house, or maintain your garage at a comfortable temperature. Even difficult-to-maintain rooms are easily controlled with a multi-unit system, because each area has its own control unit. All this adds up to maximum comfort, maximum efficiency, and minimum utility bills.
   
• Cost Effective Choice. Ductless split systems are an easy solution to bring comfort to rooms without ductwork or with hot or cold spots. Installation of your new ductless mini split is minimally invasive with no patching or painting required. This makes a ductless system a much more cost-effective solution than adding ductwork or increasing the capacity of your home's current heating & air conditioning system. These high-efficiency HVAC systems can also help you save money by helping to keep your most-used rooms optimally comfortable, so that even if you have ductwork, you can potentially spend less on heating and cooling costs for the rest of your home.
   
• High Efficiency Systems. Lennox ductless systems have efficiencies up to 23 SEER and Mitsubishi Electric systems offer efficiencies up to 26 SEER. Both systems qualify as Energy Star rated.
   
• Wirelessly Control Each Space. Comfort is more than controlling heating and cooling. It’s being able to do it effortlessly. A wireless remote control option is another way a ductless mini-split offers personal comfort from every angle.
   
• New Technology revolutionizes the heat pump. Unlike older, inefficient heat pumps, with Mitsubishi Electric’s systems cold air delivery is eliminated. Larger coils heat faster, and the Hot Start™ system doesn’t activate the fan until the desired temperature is reached so it never blows cold air.
   
• Variable Speed, High Efficiency. More than just a comfort solution, Lennox Ductless Split systems are a high-efficiency alternative to other room-by-room products like window air conditioners. In these high-efficiency ductless HVAC systems, the dehumidification you gain in cooling mode is amplified because of Lennox's variable-speed technology, allowing the system to run longer cycles at lower fan speeds. This prolonged dehumidification can actually make you feel more comfortable at a higher temperature setting. Which is energy savings that stay in your wallet!
   
• Quiet Operation & Allergen Filtration. Mitsubishi Electric offers advanced multi-stage filtration systems that dramatically reduce allergens and help eliminate odors. And their indoor units operate with sound levels starting as low as 19dB; that’s even quieter than a human whisper.
