KINGSPORT, TN – November 13, 2026 – PRESSADVANTAGE –
ATC Cooling & Heating, a Kingsport-based HVAC contractor specializing in ductless mini-split systems, has released guidance for homeowners facing persistent hot and cold spots as the region moves through the final weeks of summer. The information centers on how ductless mini-split systems can deliver targeted cooling to individual rooms and spaces where extending conventional ductwork is impractical or undesirable.
The guidance follows the company’s earlier material on ductless heat pumps for late-summer room cooling and expands the discussion toward zoned, room-by-room applications. According to the company, ductless systems are frequently installed in home additions, converted garages, finished attics, bonus rooms, and sunrooms where tying into an existing central system would require significant construction. Because each indoor unit operates independently, homeowners can condition a single space without cooling the entire home.
The company notes that uneven temperatures are among the more common comfort complaints in the Tri-Cities area, where the temperate four-season climate produces warm summers and mild winters. Rooms that sit far from a central air handler, spaces above garages, and additions built after original construction often warm more quickly than the rest of a residence. Ductless mini-split systems address these situations by placing a dedicated indoor unit in the affected area, connected to an outdoor unit without the need for extensive ductwork.
“Many of the calls we receive involve a single room that never seems to match the rest of the house,” said Nathan Schmitt of ATC Cooling & Heating. “A ductless mini-split lets a homeowner treat that one space directly rather than reworking an entire central system. It is often the most practical approach for additions and converted rooms where running new ducts simply does not make sense.”
ATC Cooling & Heating installs ductless systems from Mitsubishi and Daikin and provides installation, maintenance, and repair services across the region. The company also advises homeowners on available rebates and incentives associated with ductless heat pump systems. Each indoor unit can be set to its own temperature, allowing different areas of a home to be managed according to how they are used.
Schmitt added that the room-by-room design offers flexibility beyond a single installation. “A homeowner can start with one zone and add units over time as needs change,” he said. “That scalability is part of why ductless systems fit so many different households.”
The company profile reflects more than 50 years of experience serving residential and light commercial clients throughout the Tri-Cities, including Johnson City, Kingsport, Bristol, and surrounding communities from Abingdon, Virginia, to Limestone, Tennessee. New equipment installations include a 36-month labor warranty in addition to the manufacturer parts warranty, and the company offers yearly maintenance tune-ups to support long-term performance.
