KINGSPORT, TN – October 30, 2026 – PRESSADVANTAGE –

ATC Cooling & Heating has released new guidance for Tri-Cities homeowners who struggle with uneven temperatures, explaining how ductless mini-split systems can target hot and cold spots on a room-by-room basis. The Kingsport-based contractor issued the information as part of an ongoing educational series covering ductless heat pump technology, following an earlier discussion of ductless cooling during the late-summer months.

The company reports that many homes contain spaces that conventional central systems cool unevenly, including room additions, finished attics, converted garages, sunrooms, and areas located far from existing ductwork. In these situations, extending traditional ducting can be difficult or impractical. Ductless systems address the problem by pairing an outdoor unit with one or more indoor units, each serving a specific zone and operating independently of the rest of the home.

According to ATC Cooling & Heating, this zoned approach allows temperatures to be adjusted by area rather than applying a single setting throughout the structure. The company notes that ductless mini splits are often used to supplement an existing HVAC system or to serve spaces that were never connected to central ductwork, giving homeowners a way to condition problem areas without major renovation.

“Many of the comfort complaints we hear come down to a single room that never feels right, whether that is an addition over a garage or a back bedroom that sits too far from the main system,” said Nathan Schmitt of ATC Cooling & Heating. “Ductless mini splits let a homeowner treat that specific space on its own terms instead of overcooling the entire house to compensate.”

The company serves residential and light commercial clients throughout the Tri-Cities area and works with ductless equipment from manufacturers including Mitsubishi and Daikin. Its services cover installation, maintenance, and repair of ductless heat pump and air conditioning systems, along with guidance on available rebates and incentives for qualifying installations.

Schmitt added that the room-by-room design of ductless technology makes it adaptable to a range of home layouts. “Because each indoor unit runs on its own, a homeowner can start with one trouble spot and expand later if other areas need attention,” he said. “That flexibility is part of why these systems fit so many older homes in this region.”

The information released through this listing reflects the company’s stated focus on matching equipment to the specific conditions of each home and the four-season climate of the Kingsport area, which combines warm summers with mild winters. ATC Cooling & Heating indicated that additional installments in the series will address zone control and the transition from late-summer cooling into fall heating.
